AGLAOTHAMNION WESTBROOKIAE SP. NOV. (RHODOPHYTA), A SPECIES PREVIOUSLY CONFUSED UNDER THE NAME CALLITHAMNION BYSSOIDES1

We propose the name Aglaothamnion westbrookiae sp. nov. for the alga referred to as Callithamnion byssoides Arnott ex Harvey in Hooker by Edwards and others from the eastern coast of North America. A. westbrookiae differs from the European A. byssoides (Arnott ex Harvey in Hooker) L'Hardy-Halos et Rueness (= C. byssoides, type locality Cornwall, England) by having fronds branched pinnately, not spirally as in A. byssoides. The gonimolobes in A. westbrookiae are rounded, not conical and lobed as in A. byssoides. The spermatangia are in dense hemispherical clusters whereas in A. byssoides the equivalent structure is elongated. The two taxa are sexually incompatible. Aglaothamnion westbrookiae also differs in morphological features and is not interfertile with A. pseudobyssoides from France. We suggest that A. westbrookiae and A. feldmanniae Halos from Europe are similar in most features, including the involucral branches subtending carposporophytes. However, cross-ability tests demonstrated that they are not interfertile, and differences in vegetative structure suggest that they should be treated as two different species.     

CRYPTOPERIDINIOPSIS BRODYI GEN. ET SP. NOV. (DINOPHYCEAE), A SMALL LIGHTLY ARMORED DINOFLAGELLATE IN THE PFIESTERIACEAE1

A new genus and species of heterotrophic dinoflagellate, Cryptoperidiniopsis brodyi gen. et sp. nov., are described. This new species commonly occurs in estuaries from Florida to Maryland, and is often associated with Pfiesteria piscicida Steidinger et Burkholder, Pseudopfiesteria shumwayae (Glasgow et Burkholder) Litaker et al., and Karlodinium veneficum (Ballantine) J. Larsen, as well as other small (<20 μm) heterotrophic and mixotrophic dinoflagellates. C. brodyi gen. et sp. nov. feeds myzocytotically on pigmented microalgae and other microorganisms. The genus and species have the enhanced Kofoidian plate formula of Po, cp, X, 5′, 0a, 6″, 6c, PC, 5+s, 5″′, 0p, and 2″″ and are assigned to the order Peridiniales and the family Pfiesteriaceae. Because the Pfiesteriaceae comprise small species and are difficult to differentiate by light microscopy, C. brodyi gen. et sp. nov. can be easily misidentified.     

ON THE IDENTITY OF KARLODINIUM VENEFICUM AND DESCRIPTION OF KARLODINIUM ARMIGER SP. NOV. (DINOPHYCEAE), BASED ON LIGHT AND ELECTRON MICROSCOPY,NUCLEAR‐ENCODED LSU RDNA,AND PIGMENT COMPOSITION1

An undescribed species of the dinoflagellate genus Karlodinium J. Larsen (viz. K. armiger sp. nov.) is described from Alfacs Bay (Spain), using light and electron microscopy, pigment composition, and partial large subunit (LSU) rDNA sequence. The new species differs from the type species of Karlodinium (K. micrum (Leadbeater et Dodge) J. Larsen) by lacking rows of amphiesmal plugs, a feature presently considered to be a characteristic of Karlodinium. In K. armiger, an outer membrane is underlain by a complex system of cisternae and vacuoles. The pigment profile of K. armiger revealed the presence of chlorophylls a and c, with fucoxanthin as the major carotenoid. Phylogenetic analysis confirmed K. armiger to be related to other species of Karlodinium; thus forming a monophyletic genus, which, in the LSU tree, occupies a sister group position to Takayama de Salas, Bolch, Botes et Hallegraeff. The culture used by Ballantine to describe Gymnodinium veneficum Ballantine (Plymouth 103) was examined by light and electron microscopy and by partial LSU rDNA. Ultrastructurally, it proved identical to K. micrum (cultures Plymouth 207 and K. Tangen KT‐77D, the latter also known as K‐0522), and in LSU sequence, differed in only 0.3% of 1438 bp. We consider the two taxa to belong to the same species. This necessitates a change of name for the most widely found species, K. micrum, to K. veneficum. The three genera Karlodinium, Takayama, and Karenia constitute a separate evolutionary lineage, for which the new family Kareniaceae fam. nov. is suggested.     

STRUCTURALLY PRESERVED PLANTS FROM SOUTHEASTERN KENTUCKY: STAUROPTERIS BISERIATA SP. NOV.

Several axes of the coenopterid fern Stauropteris are described from permineralized peat associated with Lower-Middle Pennsylvanian coal deposits of southeastern Kentucky. This represents the first documented report of the genus in North America. The specimens are regarded as representatives of a new species—S. biseriata—based on the distinctive branching habit. Three branch orders are described, and in each case, branches are singular and distichous, arranged in a two-ranked pattern. This is in contrast to other species of Stauropteris in which the branches are paired and form a quadriseriate pattern. A pair of vascularized aphlebiae subtend each branch through all branching orders. Aphlebiae associated with first- and second-order branches are three-parted at the point of insertion; those that subtend third-order branches are singular. Stauropteris and a number of Devonian fern-like plants are compared on the basis of certain morphological similarities.     

辽宁西部早三叠世苏铁植物一新属--Mediocycas gen. nov.及其演化意义

报道苏铁植物大孢子叶化石一新属———中间苏铁属(Mediocycasgen.nov.)。标本采集于辽宁省西部,喀左县杨树沟煤矿后山的早三叠世红砬组。这些标本以前曾被处理为疑问化石(Problematicum)。因当时资料不足,所以没有确定属种名称。但鉴于这些化石在苏铁类早期起源与演化研究中具有重要意义,故对它们作了重新研究。文中除了以喀左中间苏铁(Mediocycaskazuoensisgen.etsp.nov.)为典型种进行描述以外,还对新属、种在苏铁类起源与演化方面的意义作了较为详细的讨论。     

DEUCALION GEN. NOV. AND ANISOSCHIZUS GEN. NOV. (CERAMIACEAE,CERAMIALES), TWO NEW PROPAGULE-FORMING RED ALGAE FROM SOUTHERN AUSTRALIA1

Two new propagule-farming red algae from southern Australia, Deucalion levringii (Lindauer) gen. et comb. nov. and Anisoschizus propaguli gen. et sp. nov., are described and defined largely on their development in laboratory culture. Deucalion is included in the tribe Compsothamnieae on the basis of its subapical procarp and alternate distichous branching. It differs from the other genera included in that tribe in that it produces 3-celled propagules, polysporangia, a subapical cell of the fertile axis which bears 3 pericentral cells, and an apparently post-fertilization involucre which develops from the hypogenous and sub-hypogenous cells of the fertile axis. Its gametophyte morphology has been elucidated in culture, as only sporophytes are known from the field. Gametophytes do not appear to produce propagules. Anisoschizus is provisionally included in the tribe Spermothamnieae on the basis of its subdichotomous branching, possession of a prostrate system and the production of polysporangia. It differs from the other genera of the tribe in the production of 2-celled propagules. Observations on the germination of the “monosporangia” of Mazoyerella arachnoidea and Monosporus spp. indicate that they are analagous to the propagules of Deucalion and Anisoschizus. The nature of these propagules and their role in recycling the parent plant are discussed and contrasted with true monosporangia. It is recommended that Monosporus be maintained as a form genus containing representatives from more than one tribe, as exemplified by plants from Lord Howe I. provisionally identified as M. indicus Boergesen which have both prostrate and erect, as opposed to only erect, axes.     

DIAPHORODENDRACEAE,FAM. NOV. (LYCOPSIDA: CARBONIFEROUS): SYSTEMATICS AND EVOLUTIONARY RELATIONSHIPS OF DIAPHORODENDRON AND SYNCHYSIDENDRON,GEN. NOV.

Synchysidendron, gen. nov., is segregated from Diaphorodendron DiMichele emend. Both genera are determinate, rhizomorphic, arborescent lycopsids that share identical reproductive organs but differ radically in growth architecture and consequently in the timing of reproduction. Cones in Synchysidendron (two species) are borne on late-formed crown branches; in Diaphorodendron (three species) cones are borne on deciduous lateral branches, produced over much of the life of the tree. The two genera also differ in several characteristics of the stele and periderm. We hypothesize that Diaphorodendron gave rise to Synchysidendron within their shared Late Carboniferous coal-swamp habitat, by heterochronic suppression of lateral branching during ontogeny. Together, these genera form a highly apomorphic clade, here recognized as the new family Diaphorodendraceae, that is distinguished primarily by siphonostelic axes, a bifacial periderm, distinctive megasporangia, and gulate megaspores.     

中国弯颈霉新种及产环孢菌素的研究

对云南省迪庆藏族自治州产的冬虫夏草 Cordyceps sinensis(Berk.)Sacc.进行分离获一纯种,经培养鉴定确为弯颈霉属 Tolypocladium w.Gams 一新种,命名为中国弯颈霉 To-lypocladium sinense c.L.Li sp.nov.。它在几种琼脂培养基上生长形成瓶梗及瓶梗孢于,瓶梗基部呈球形或椭圆形膨大,瓶颈细长而弯曲,瓶梗孢子球形至卵形。其形态特征及生活习性与弯颈霉属其它种类显然不同,故定为一新种。它在蛋白胨葡萄糖培养液中,温度26℃,pH5.2,摇瓶振荡培养12天。发酵液用乙酸乙酯萃取,减压蒸馏,从每升发酵液中获50—80mg 环孢菌素粗品。对几种半知真菌显示了明显的拮抗作用。     

ULTRASTRUCTURE AND 18S RRNA GENE SEQUENCE FOR PELAGOMONAS CALCEOLATA GEN. ET SP. NOV. AND THE DESCRIPTION OF A NEW ALGAL CLASS,THE PELAGOPHYCEAE CLASSIS NOV.1

Pelagomonas calceolata gen. et sp. nov., an ultra-planktonic marine alga, is described using electron microscopy and the cytoplasmic small subunit (18S) ribosomal RNA (rRNA) gene sequence. Cells are uniflagellate, about 1.5 × 3 μm in size. The flagellium has two rows of bipartite hairs, the paraxonemal rod has a dentate appearance, and a two-gyred transitional helix is present between two transitional plates. Microtubular roots, striated roots, and a second basal body are absent. A thin organic theca surrounds most of the cell. There is a single chloroplast with a girdle lamella and a single, dense mitochondrion with tubular cristae. A single Golgi body with swelled cisternae lies beneath the flagellum, and each cell has an ejectile organelle that putatwely releases a cylindrical structure. A vacuole, or cluster of vacuoles, contains the putative carbohydrate storage product. The 18S rRNA gene was sequenced completely in both directions, excluding three primer regions. When compared to the same gene sequence from other organisms, Pelagomonas calceolata gen. et sp. nov. occupies an unresolved position among other chromophyte algae and is distinct from members of any of these classes. Based on morphological, ultrastructural, and molecular data, we describe this alga as a new species, and we place this highly unusual new species in a new genus, family, order, and class.     

Regulated, but not constitutive, secretory proteins bind porcine chymotrypsinogen.

Endocrine and exocrine cells exhibit both a constitutive and a regulated secretory pathway. In the latter pathway, secretory proteins are stored at a high concentration in secretory granules and are released by exocytosis in response to appropriate external stimuli. Sorting between the two secretory pathways is believed to take place in the trans-Golgi tubular network. To account for experimental data, it has been proposed that sorting receptors exist which bind a variety of regulated secretory proteins, including foreign secretory proteins introduced into the cells by transfection. In support of the sorting receptor hypothesis Chung et al. (Chung, K.-N., Walter, P., Aponte, G. W., and Moore, H.-P.H. (1989) Science 243, 192-197) isolated a group of 25-kDa canine pancreatic "hormone-binding proteins" that bound regulated but not constitutive secretory proteins. To determine if similar proteins are present in other species and tissues, we have screened porcine pancreas, parathyroid, adrenal medulla, and pituitary glands. A 31-kDa protein, similar to that identified by Chung et al. (1989), which binds to regulated but not to constitutive secretory proteins was identified in porcine pancreas. This protein was not detected in the parathyroid, adrenal medulla, or pituitary glands, however, which argues against it serving as a general sorting receptor. NH2-terminal sequencing, immunoreactivity, and proteolytic activity data indicate that the porcine 31-kDa protein is similar if not identical to porcine chymotrypsinogen A or B.     

T4 gene 32 protein trypsin-generated fragments. Fluorescence measurement of DNA-binding parameters.

The intrinsic fluorescence of the T4 helix-destabilizing protein specified by gene 32 (32P) is not altered by the proteolytic removal of either the 6200-dalton COOH-terminal "A" region (32P*-A) or both the A and the 2300-dalton NH2-terminal "B" region (32P*-(A + B)). The intrinsic fluorescence of 32P, 32P*-A, and 32P*-(A + B) is decreased 23% by the addition of d(pT)8 and 34% by the addition of poly(dT). Saturation binding curves of the percentage of change in protein fluorescence as a function of nucleotide concentration show that the intact 32P as well as the two proteolysis-generated fragments all have association constants of approximately 10(6) M-1 for d(pT)8. This demonstrates that the DNA binding site is not contained within either the A or B regions of 32P. Both 32P and 32P*-A bind cooperatively to poly(dT) as evidenced by a 400- to 1000-fold increase in association constant for poly(dT) compared to d(pT)8. Since within the limits of our measurements 32P and 32P*-A bind equally well to poly(dT) (Kassoc approximately 5 . 10(8) M-1), the enhanced helix-destabilizing properties previously reported for 32P*-A cannot be accounted for by a significant increase in binding affinity of 32P*-A for single-stranded DNA. The binding constant for the 32P*-(A + B):poly(dT) complex is only 3-fold higher than that for the 32P*-(A + B):d(pT)8 complex, which confirms our proposal that the B region is essential for cooperative 32P:32P protein interactions.     

PROPOSAL OF THE EUPTILOTEAE HOMMERSAND ET FREDERICQ,TRIB. NOV. AND TRANSFER OF SOME SOUTHERN HEMISPHERE PTILOTEAE TO THE CALLITHAMNIEAE (CERAMIACEAE,RHODOPHYTA)1

Morphological and molecular studies demonstrate that the tribe Ptiloteae (Ceramiaceae, Ceramiales) is polyphyletic. The Ptiloteae, sensu stricto, occur only in the Northern Hemisphere and all Southern Hemisphere representatives belong in other tribes. Three genera (Euptilota, Seirospora, and Sciurothamnion) are transferred to the Euptiloteae Hommersand et Fredericq, trib. nov., and the Callithamnieae is revised to include three Ptilota‐like genera, Georgiella, Falklandiella, and Diapse, and two new genera. Heteroptilon Hommersand, gen. nov. is erected to receive Euptilota pappeana Kützing 1849 and Aglaothamnion rigidulum De Clerck, Bolton, Anderson et Coppejans 2004 from South Africa, and Aristoptilon Hommersand et W. A. Nelson, gen. nov. is established to receive Euptilota mooreana Lindauer 1949 from New Zealand. The principal difference between the Euptiloteae and the Callithamnieae is seen in the earliest stages after fertilization. The fertilized carpogonium enlarges and forms a pair of tube‐like protuberances directed toward the auxiliary cells that are cut off as connecting cells in the Euptiloteae, whereas in the Callithamnieae the carpogonium usually divides into two cells, each of which cuts off a small connecting cell that fuses with an adjacent enlarging auxiliary cell. Nuclei are terminal in spermatangia of the Euptiloteae, subtended by mucilaginous vesicles, and are medial in the Callithamnieae situated between apical and basal vesicles. The Euptiloteae and Callithamnieae (including the Ptilota‐like members) are each strongly supported in maximum‐likelihood tree topologies resulting from analyses of combined 18S rDNA, 28S rDNA, 16S rDNA, and rbcL data sets. Their sister relationship is also well supported.

青藏高原小麦白秆病病原菌——小麦壳月孢的研究

五十年代以来,小麦白秆病先后发生于我国的四川、青海和西藏的高寒地区。由于是一种摧毁性病害,很快受到有关方面的研究,测定出有效的防治措施并推广,从而限制了该病的扩展和危害。但在病原菌方面,过去国内一些研究者虽先后几经研究,不仅未能获得统一的学名且有错误的鉴定。因此,有必要再研究,以便正确地识别此菌的分类位置。作者据川、青、藏高原收集到的该菌标本及培养物切片和染色进行镜检,观察到小麦白秆病菌的产孢结构是瓶梗型的,确实应隶属于壳月孢属(Selenophoma)内,并以此菌的形态特征也不同于壳月孢属内的其它种,因而认为是一新种——小麦壳月孢(Selenophoma tritici sp.nov.),文中对新种作了形态特征的汉文和拉丁文描述和附图。此外,还阐明了现代半知菌类分类中产孢细胞的特征的重要性。模式标本存放于中国科学院微生物研究所真菌标本室(HMAS)。     

NOTE. NEW EUENDOLITHIC CYANOBACTERIA FROM THE BAHAMA BANK AND THE ARABIAN GULF: HYELLA RACEMUS SP. NOV.1

A new species of endolithic cyanobacteria, Hyella racemus sp. nov. (order Pleurocapsales), penetrates ooid grains in actively shoaling sands in shallow (0.5–5 m) waters of the Bahama carbonate platform and the Arabian Gulf. Hyella racemus is characterized by prolific branching, resulting in dense grape-like cell clusters that penetrate the carbonate substrate. The clusters radiate inward and form deep, isodiametric pits. Resin casts of these pits are framboid (raspberry-like) in shape. The borehole morphology conforms with the shape of the endolith body and can be identified in resin-cast preparations. Cell division is by cleavage with regular alternation of division planes. The sheath is tight, layered, and colorless or yellow-brown when under strong illumination. The new species is one of the most common endoliths in ooids of the Bahamas and the Arabian Gulf It differs from other members of this endolithic genus by its branching pattern and less prominent apical cells.     

MUMMPIKIA GEN. NOV. AND THE ORIGIN OF CALCITIC-SHELLED BRACHIOPODS

Abstract:  Phosphatised limestone-hosted and shale-hosted specimens of the obolellid Mummpikia nuda gen. et comb. nov. and two further unidentified obolellids from the Early Cambrian Mural Formation (Jasper National Park, Canadian Rocky Mountains) provide novel insights into the shell microstructure of obolellids and the nature of their pedicle. The shell was penetrated by abundant canals of a sub- μ m diameter and the anterior tip of the delthyrium forms a projection into the body cavity that is penetrated by a thin canal. It is argued that both shell microstructure and posterior margin are linguliformean characters and that obolellids hold a position basal in the rhynchonelliform stem-group.

MOLECULAR PHYLOGENY,ULTRASTRUCTURE, AND TAXONOMIC REVISION OF CHLOROGONIUM (CHLOROPHYTA): EMENDATION OF CHLOROGONIUM AND DESCRIPTION OF GUNGNIR GEN. NOV. AND RUSALKA GEN. NOV.1

We examined the molecular phylogeny and ultrastructure of Chlorogonium and related species to establish the natural taxonomy at the generic level. Phylogenetic analyses of 18S rRNA and RUBISCO LSU (rbcL) gene sequences revealed two separate clades of Chlorogonium from which Chlorogonium (Cg.) fusiforme Matv. was robustly separated. One clade comprised Cg. neglectum Pascher and Cg. kasakii Nozaki, whereas the other clade included the type species Cg. euchlorum (Ehrenb.) Ehrenb., Cg. elongatum (P. A. Dang.) Francé, and Cg. capillatum Nozaki, M. Watanabe et Aizawa. On the basis of unique ultrastructural characteristics, we described Gungnir Nakada gen. nov. comprising three species: G. neglectum (Pascher) Nakada comb. nov., G. mantoniae (H. Ettl) Nakada comb. nov., and G. kasakii (Nozaki) Nakada comb. nov. We also emended Chlorogonium as a monophyletic genus composed of Cg. euchlorum, Cg. elongatum, and Cg. capillatum. Because Cg. fusiforme was distinguished from the redefined Chlorogonium and Gungnir by the structure of its starch plate, which is associated with pyrenoids, we reclassified this species as Rusalka fusiformis (Matv.) Nakada gen. et comb. nov.
