A new name for Torula glutinosa in Heteroconium

Torula glutinosa, a sooty mold on living leaves and stems of Eriodictyon spp. from California is illustrated and described. It shares, with the type species of Heteroconium, H. citharexyli, acropetal conidiogenesis of chains of conidia of variable length and acropetal transseptation. An unnamed synanamorph is recognized and described.     

The fine structure of conidial development in the genus Torula. II. T. caligans (Batista and Upadhyay) M. B. Ellis and T. terrestris Mistra.

Conidia of Torula caligans (Batista & Upadhyay) M. B. Ellis comb.nov. and T. terrestris Misra were examined by transmission- and scanning-electron microscopy. Torula caligans produced four-celled conidia in which the central cells were distinctly larger than the basal and apical cells. Conidia of T. terrestris were 4- to 7-celled long and ellipsoidal in shape. Conidiogenous cells in both species developed melanin only within the lowermost part of the lateral walls while the other cells of the conidium were uniformly melanized around the circumference of the cell; melanin in these cells being deposited within, at least, half the width of the cell wall. In both species new conidia arose from evagination of the hyaline apex of the conidiogenous cell and are therefore blastoconidia. The systematic relationships between T. caligans and T. terrestris and other species of the genus Torula are discussed.     

SULCOPYRENULA,A NEW PYRENOCARPOUS LICHEN GENUS (PYRENULACEAE,LICHENIZED ASCOMYCOTA)

Sulcopyrenula H. Harada gen. nov. is described. It differs from other genera ofPyrenulaceae by having longitudinally sulcate spores. The genus is represented by two species: S. canellae-albae (Fée) H. Harada comb. nov. and S. staurospora (Tuck.) H. Harada comb. nov. Both species have been previously reported from N. and S. America, and the latter species is now reported from Asia.

A new species of Pseudorobillarda, an endophyte from Thuja occidentalis in Canada, and a key to the species

Pseudorobillarda monica sp. nov. is described and illustrated. The endophyte was isolated from living leaves and bark of twigs of a Thuja occidentalis bonsai (>90 years old) at the Montréal Botanical Garden and ornamental trees in Montréal urban plantations. This pycnidial fungus is typical of the genus in morphology but clearly differs from other species in Pseudorobillarda by the distinct size of the conidiomata and the shape and size of conidia and paraphyses. Its taxonomic placement is discussed and a key to the species of Pseudorobillarda is provided.     

Synonymy of Etiennea Matile-Ferrero with Hemilecanium Newstead (Hemiptera: Coccidae), based on morphology of adult females, adult males and first-instar nymphs, and description of a new potential pest species from the Ryukyu Archipelago, Japan

The genus Etiennea Matile‐Ferrero is synonymized with Hemilecanium Newstead (Hemiptera: Coccidae). We base this decision on a morphological comparative study of adult females, adult males and first‐instar nymphs (crawlers), including a phylogenetic analysis. We recovered a sister group relationship between the type species of the two genera, Etiennea villiersi Matile‐Ferrero and Hemilecanium theobromae Newstead; that is, each was more closely related to the other than either was to other species in their respective genera. All species hitherto included in Etiennea are transferred to Hemilecanium: H. bursera (Hodgson & Kondo) comb. nov., H. cacao (Hodgson) comb. nov., H. candelabra (Hodgson) comb. nov., H. capensis (Hodgson) comb. nov., H. carpenteri (Newstead) comb. nov., H. cephalomeatus (Hodgson) comb. nov., H. combreti (Hodgson) comb. nov., H. ferina (De Lotto) comb. nov., H. ferox (Newstead) comb. nov., H. gouligouli (Hodgson) comb. nov., H. halli (Hodgson) comb. nov., H. kellyi (Brain) comb. nov., H. madagascariensis (Hodgson) comb. nov., H. montrichardiae (Newstead) comb. nov., H. multituberculum (Hodgson) comb. nov., H. petasus (Hodgson) comb. nov., H. sinetuberculum (Hodgson) comb. nov., H. tafoensis (Hodgson) comb. nov., H. ulcusculum (Hodgson) comb. nov., and H. villiersi (Matile‐Ferrero) comb. nov. Keys to the adult females of all 26 species and known adult males and first‐instar nymphs are provided. The adult males and first‐instar nymphs of H. theobromae Newstead and E. villiersi Matile‐Ferrero are for the first time fully described and illustrated. One new potential pest species of Hemilecanium, H. uesatoi Kondo & Hardy sp. nov., which was collected on three islands of the Ryukyu Archipelago, Japan, is described and illustrated based on the adult female, adult male and first‐instar nymph. We discuss evidence that H. uesatoi is a new introduction to the Ryukyu Archipelago. The first‐instar nymphs of Hemilecanium can be divided into two distinct morphological groups, the petasus group and the theobromae group.     

The genusBrachydesmiella from submerged wood in the tropics, including a new species and a new combination

During studies of fungi occurring on wood submerged in freshwater streams in the tropics, five species ofBrachydesmiella, namely,B. anthostomelloidea, B. biseptata, B. caudata, B. orientalis comb. nov., andB. verrucosa sp. nov., were collected. There are described and illustrated from natural substrata, wooden test blocks, and from pure culture, based mainly on collections made in Thailand.Brachydesmiella verrucosa differs from the other four species in having 3-celled, coarsely verrucose, ampoule-shaped conidia, with a long, thin, cylindrical, verruculose apical cell. A key toBrachydesmiella species is provided.

绿僵菌属的三个新种

作者从广东、贵州、北京等地收集的虫生真菌中,发现在我国具有绿僵菌属特征的真菌可分为四个种。根据菌落颜色、分生孢子团块大小、紧密和牢固程度、孢子链连接方式、分生孢子形状等,将我们收集的属于本属的菌株分为四个种。本文报道绿僵菌属三个新种的描述。金龟子绿僵菌Metarhizium anisopliae(Metsch.)Sorokin为最常见的甘蔗金龟子致病菌,是本属的模式种。平沙绿僵菌Metarhizium pingshaense Chen et Guo sp.nov.、柱孢绿僵菌Metarhizium cylindrosporae Chen et Guo sp.nov.和贵州绿僵菌Metarhizium guizhouense Chen et Guo sp.nov.是三个新种。     

Two new species of Botryosphaeria with brown, 1-septate ascospores and Dothiorella anamorphs

Botryosphaeria sarmentorum sp. nov. and B. iberica sp. nov. are described and illustrated. These two species are unusual in this genus because of their brown, 1-septate ascospores. Phylogenetic analysis based on ITS and EF1-alpha sequences place them within the clade containing species with Fusicoccum anamorphs. The brown, 1-septate conidia, however, do not conform to Fusicoccum. Therefore phylogenetically and morphologically the anamorphs of these two species belong in a genus distinct from any of the currently accepted anamorph genera assigned to Botryosphaeria. Through a study of the type species of Dothiorella this genus is resurrected to accommodate anamorphs of Botryosphaeria with brown, 1-septate conidia. Botryosphaeria sarmentorum is shown to be the teleomorph of Diplodia sarmentorum, which in turn is transferred to Dothiorella. Otthia quercus is transferred to Botryosphaeria as B. quercicola nom. nov.

Morphological and Molecular Characterization of Some Peritrichs (Ciliophora: Peritrichida) from Tank Bromeliads, Including Two New Genera: Orborhabdostyla and Vorticellides

Using standard methods, we studied the morphology and 18S rDNA sequence of some peritrich ciliates from tank bromeliads of Costa Rica, Jamaica, and Ecuador. The new genus Orborhabdostyla differs from Rhabdostyla by the discoidal macronucleus. Two species from the literature and a new species from Ecuadoran tank bromeliads are combined with the new genus: O. previpes (Claparède and Lachmann, 1857) nov. comb., O. kahli (Nenninger, 1948) nov. comb., and O. bromelicola nov. spec. Orborhabdostyla bromelicola is a slender species with stalk-like narrowed posterior half and operculariid/epistylidid oral apparatus. An epistylidid relationship is also suggested by the gene sequence. Vorticella gracilis, described by Dujardin (1841) from French freshwater, belongs to the V. convallaria complex but differs by the yellowish colour and the number of silverlines. The classification as a distinct species is supported by the 18S rDNA, which differs nearly 10% from that of V. convallaria s. str. Based on the new data, especially the very stable yellowish colour, we neotypify V. gracilis with the Austrian population studied by Foissner (1979). Vorticella gracilis forms a strongly supported phyloclade together with V. campanula, V. fusca and V. convallaria, while Vorticellides astyliformis and Vorticella microstoma branch in a separate, fully-supported clade that includes Astylozoon and Opisthonecta. The new genus Vorticellides comprises five small (usually < 60 μm), barrel-shaped species with two epistomial membranes: V. aquadulcis (Stokes, 1887) nov. comb., V. astyliformis (Foissner, 1981) nov. comb., V. platysoma (Stokes, 1887) nov. comb., V. infusionum (Dujardin, 1841) nov. comb., and V. (Spinivorticellides) echini (King, 1931) nov. comb. Two of these species are redescribed in the present study: V. astyliformis and V. aquadulcis, which is neotypified with a Costa Rican population. Pseudovorticella bromelicola nov. spec. differs from the congeners by the location of the two contractile vacuoles and the number of silverlines.     

Phialomyces fusiformis sp. nov. from soil in Singapore is identified and described

Phialomyces fusiformis sp. nov., isolated from soil in Singapore, is described and illustrated. The species is similar to P. macrosporus-type species of the genus but differs in that it has longer, more ellipsoid-limoniform, fusiform and more coarsely ornamented conidia.     

Phylogenetic characterization of two novel <Emphasis Type="Italic">Kamalomyces</Emphasis> species in Tubeufiaceae (Tubeufiales)

Two novel species of bambusicolous fungi in the genus Kamalomyces, collected from northern Thailand, are described and illustrated herein. Kamalomyces bambusicola and K. thailandicus spp. nov. are typical of the genus Kamalomyces (Tubeufiaceae, Tubeufiales) and are morphologically distinct from known species with respect to their size of ascomata, asci and ascospores, ascospore septation and peridium structure, including the subiculum comprising hyphae on the host surface. Morphological examination reveals that the asexual morph of K. bambusicola is associated with its sexual morph in a subiculum forming dictyochlamydosporous conidia, which are similar to the asexual morph of Chlamydotubeufia. Phylogenetic analyses of combined LSU, ITS and TEF1-α sequence data also support these two species as distinct and confirm their phylogenetic affinities within the Tubeufiaceae. In particular, Kamalomyces shares a close phylogenetic relationship to Helicoma.     

Reevaluating the classification of Halobacteroides and Haloanaerobacter species based on sequence comparisons of the 16S ribosomal RNA gene

Abstract The 16S rRNA gene (rDNA) sequence analysis of four halophilic anaerobes: Halobacteroides halobius, H. lacunaris, Haloanaerobacter (Hb.) chitinovorans and H. acetoethylicus confirmed that they were all members of the family Haloanaerobiaceae. H. lacunaris and H. halobius were found to be more closely related to each other and were distantly related to Sporohalobacter lortetti and the members of the genera Haloanaerobium and Halothermothrix . These data are in agreement with their assignment to the genus Halobacteroides . Further analysis indicated that Hb. chitinovorans was closely affiliated to members of the genus Halobacteroides , and therefore we propose to transfer it to the genus Halobacteroides as H. chitinovorans comb. nov. This transfer would invalidate the genus Haloanaerobacter , as Hb. chitinovorans is the only member of this genus. The 16S rDNA sequence analysis of H. acetoethylicum indicated that it was very closely related to members of the genus Haloanaerobium , viz. Haloanaerobium (Ha.) praevalens, Ha. salsugo , and Ha. alcaliphilum , and hence we propose to transfer it to the genus Haloanaerobium as Ha. acetoethylicus comb. nov.     

Orbilia blumenaviensis and its Arthrobotrys anamorph

A member of the nematophagous anamorph genus Arthrobotrys was isolated from its teleomorph Orbilia blumenaviensis comb. nov. (= Orbilia fici), a species closely related to O. auricolor but deviating in having lanceolate paraphyses. In the presence of nematodes, the anamorph forms three-dimensional adhesive networks. A trimorphism in its conidia was observed which vary in shape and number of septa. In the first isolate, two types of heteropolar conidia were obtained. These differ markedly from the type strain of A. vermicola, which forms mainly homopolar (fusoid) conidia. In a further ascospore isolate of O. blumenaviensis, however, mainly fusoid conidia referable to A. vermicola occurred. Combining morphological and phylogenetic analysis, we conclude that these isolates with differently shaped conidia and/or differences in the ITS rDNA (ca. 2–4%) belong to a single anamorph species, A. vermicola. Both teleomorph and anamorph are illustrated and described.

Diversity of acaropathogenic fungi in Poland and other European countries

The occurrence, species diversity and some aspects of taxonomical affinity and host selectivity of acaropathogenic fungi associated with phytophagous, saprotrophic and predacious mites in Poland and other European countries were investigated on wild and cultivated plants, in insect feeding sites under the bark and in decayed wood. From among 33 species of fungi affecting mites only five species of Entomophthorales were separated and the most numerous were Neozygites floridana mostly on Tetranychus urticae, N. abacaridis on a few eriophyid species, and Conidiobolus coronatus attacking gamasid mites most frequently of the genus Dendrolaelaps. The most frequent mite pathogens occurring in mite communities on plants and in wood infested by insects were of the genus Hirsutella. Until now 13 of their form-species have been recognized in these habitats, but only H. kirchneri, H. necatrix and H. thompsonii (including its variety synnematosa) can be treated as exclusive oligophagous pathogens of phytophagous mites, though their potential host range seems to embrace only selected eriophyid or tarsonemid mites. Taxonomical differentiation of fungal strains was based on close morphological observations and molecular analysis of ITS region sequences. Two new species of acaropathogenic fungi were described in these studies. Hirsutella danubiensis sp. nov. was found in the tetranychid T. urticae, whereas H. vandergeesti sp. nov. affected phytoseiid mites of the genera Amblyseius, Neoseiulus, Seiulus and Typhlodromus, and the tarsonemid Tarsonemus lacustris.
