A new species of <Emphasis Type="Italic">Phellinus</Emphasis> sensu stricto associated with esca on grapevine in South Africa

A new species of Phellinus sensu stricto was isolated from diseased Vitis vinifera in the Northern Cape and Limpopo provinces of South Africa. Phellinus resupinatus is described here based on fruit body morphology, internal transcribed spacer (ITS) and large subunit (LSU) phylogenies. Phellinus resupinatus forms a well-supported clade closely related to Phellinus bicuspidatus, a species associated with white rot in oak trees in the United States. Morphologically, P. resupinatus is characterised by its resupinate fruit body shape, straight, ventricose hymenial setae and broadly ellipsoid hyaline basidiospores. It has been isolated from esca-diseased grapevines in the summer rainfall regions of South Africa and is found on the uppermost trunks of declining vines showing symptoms of white rot.     

Phellinus caribaeo-quercicolus sp. nov., parasitic on Quercus cubana: taxonomy and preliminary phylogenetic relationships

Phellinus caribaeo-quercicolus sp. nov. is described from several collections made in western Cuba, so far exclusively on Quercus cubana. The species is characterized by a perennial, resupinate basidiomes, cushion-shaped to nodulose and multi-layered when old, apically hooked to hamate hymenial setae, and ellipsoid to broadly ellipsoid, thin- to thick-walled, hyaline to faintly yellowish basidiospores, 4.5-5.5 x 3.5-4.5 microm. The species is compared to other Phellinus species with hooked setae, especially Phellinus undulatus, also recorded in Cuba. The preliminary phylogenetic relationships of Ph. caribaeo-quercicolus within the poroid Hymenochaetales complex of genera is presented and discussed here.     

Two new setae-lessPhellinus species with large coloured spores (Fungi,Hymenochaetaceae)

Two new species ofPhellinus rimosus complex are described, viz.Phellinus coffeatoporus Kotl. etPouz. from Florida (U.S.A.) characterized by globose spores andPhellinus resinaceus Kotl. etPouz. from Papua-New Guinea and Australia which is distinguished by a very thick and faintly yellowish tinted spore wall.     

Phellinus setifer sp. nov. andP. acontextus, two noteworthy polypores from temperate areas of Japan, with notes on their allies

Type examination ofTrametes gilvoides revealed that it is distinct from the fungus hitherto known asPhellinus gilvoides in Japan.Phellinus setifer sp. nov. is described for the Japanese materials. This species is characterized by effusedreflexed basidiocarps with strigose pileus surface, often dentate dissepiments, subulate setae, and cylindrical basidiospores.Phellinus acontextus, known only from the type material collected in Nepal, is newly reported from Japan. This species is characterized by sessile and often pendent basidiocarps with multisulcate pileus surface, very thin context, lack of setae, and dark-colored basidiospores. Cultural characters of the two species are also described.Phellinus acifer comb. nov. is proposed.Phellinus contiguus andP. ferreus are newly reported from Japan.     

Three new species of Inonotus (Basidiomycota, Hymenochaetaceae) from China

Three new species of Inonotus are described and illustrated. Inonotus acutus sp. nov. is characterized by having small, thin basidiocarps with a strongly contracted base, a sharp and undulate pileus margin, ventricose hymenial setae, and ellipsoid, yellowish to yellow-brown, slightly thick-walled basidiospores. Inonotus chrysomarginatus sp. nov. differs in having an annual to perennial growth habit, pileate basidiocarps with a distinctly yellowish buff to golden-yellow margin, distinct setal hyphae and hooked hymenial setae, and broadly ellipsoid to subglobose, pale yellowish, slightly thick-walled and weakly cyanophilous basidiospores. Inonotus rigidus sp. nov. is distinguished by its resupinate and hard rigid basidiocarps, the honey-yellow pore surface, and smaller pores; microscopically, it has ellipsoid, yellowish brown and thick-walled basidiospores, and lacks both setal hyphae and hymenial setae. An identification key to the Chinese species of Inonotus sensu stricto is provided.

Coltriciella minuscula sp. nov., a new species of poroid fungus on Pinus merkusii from an Indonesian tropical forest

Coltriciella minuscula sp. nov. is described and illustrated from a specimen collected on Pinus merkusii from Bogor, Indonesia. This species is characterized by the size of its basidiocarp up to 4 mm in diam, with long hair on the stipe and with ornamented spores. Both morphological distinctiveness and phylogenetic separation based upon analyses of nrDNA ITS sequences support the establishment of this new species. Morphological dissimilarities between C. minuscula and closely related species are discussed.     

New foliicolous lichens from New Zealand 1

Three species and one genus of theTrichotheliaceae are described as new and illustrated.Polycornum rubrofuscum gen. and sp. nov. is related to the generaPorina andTrichothelium, but differs in having complex horn-like appendages growing from the entire surface of its perithecia, giving them a tomentose appearance.Trichothelium rubellum is characterized by red or brown perithecia and 5–7 white membranaceous setae arranged in a star pattern around the ostiole.Trichothelium nanum is characterized by 3-septate spores, small black perithecia, and white setae.     

HYALOPYRENIA JAPONICA,A PECULIAR NEW PYRENOCARPOUS LICHEN GENUS FROM JAPAN

Hyalopyrenia japonicaHarada (lichenized Ascomycotina) is described as a new genus on the basis of a specimen from friable rock in forests in Chiba-ken, central Japan. It is characterized by a poorly developed crustose thallus, aTrentepohliaphycobiont, immersed perithecia with hyaline walls, simple paraphyses and periphyses, non-amyloid bitunicate asci with an ocular chamber, and transversely septate hyaline spores.Hyalopyreniais monotypic, and its taxonomic position is uncertain.     

Description ofAvesicladiella gen. nov. (hyphomycetes) for two undescribed leaf litter microfungi

The new hyphomycete genusAvesicladiella with two species,A. britannica sp. nov., type species, andA. microsperma sp. nov., is described and illustrated. Both species are leaf litter microfungi. The genus closely resemblesVesicladiella, Circinotrichum, Gyrothrix, Ceratocladium andVermiculariopsiella, several hyphomycete genera with comparable characters such as superficial hyphal networks; production of setae; absence of conidiophores; lageniform or ampulliform conidiogenous cells; and hyaline aseptate conidia produced in clusters around the apices of conidiogenous cells. The new genus differs from these by its hyaline, septate setae, typical ‘phialidic’ conidiogenous cells, and hyaline, aseptate cylindrical conidia.     

Phellinus castanopsidis sp. nov. (Hymenochaetaceae) from southern China, with preliminary phylogeny based on rDNA sequences

Phellinus castanopsidis sp. nov. is described and illustrated from southern China. This species is characterized by resupinate, annual basidiomata, a dimitic hyphal system, hooked hymenial setae, and ovoid to broadly ellipsoid basidiospores that are colorless, thick-walled, weakly dextrinoid, and moderately cyanophilous. Most of these morphological features are shared by Fomitiporia ellipsoidea, P. gabonensis, and P. caribaeo-quercicolus, although in the two latter species, the basidiospores are not dextrinoid. In a phylogenetic perspective, parsimony inferences based on LSU and ITS DNA sequence data show that these four species are closely related, forming a monophyletic clade. Furthermore, this clade is more closely related to the Phellinus ignarius clade (Phellinus s.s.) than to the Fomitiporia clade. Hence, F. ellipsoidea is transferred to Phellinus, and a new combination P. ellipsoideus is proposed also.     

A fossil earthstar (Geasteraceae; Gasteromycetes) from the Late Cenozoic of Puebla,Mexico

The compressed basidiocarp of a fungus belonging to Geasteraceae (Lycoperdales; Gasteromycetes) was recovered from the plant-bearing Cenozoic strata of the Pié de Vaca Formation, Puebla, Mexico. The fossil specimen consists of an open exoperidium with ten triangular rays, and a central, circular endoperidium with an eccentrical ostiole and irregular surface relief. Scanning electron microscopy revealed a delicate reticulum on the surface of rays and on samples of the endoperidium. An acetolyzed fragment of the endoperidium yielded a few fungal spores, and similar spores were also obtained from an acetolyzed rock fragment adjacent to the fossil specimen. The fossil fungus exhibits the characteristics of extant earthstars; morphological comparison between the extant and the fossil earthstar and the type of spores obtained from the endoperidium of the latter indicate its affinity with Geastrum, although uncertainty in diagnostic characters preclude its assignment to a living species. The report of a complete basidiocarp of Geastrum from the Cenozoic of Puebla may contribute greatly to the knowledge about the spatial distribution and evolutionary history of Geasteraceae and Lycoperdales.     

Global diversity of two widespread,colony‐forming diatoms of the marine plankton,Chaetoceros socialis (syn. C. radians) and Chaetoceros gelidus sp. nov.

Marine phytoplankton samples containing diatoms of the Chaetoceros socialis group were collected from Thailand, China, Denmark, and Greenland, and cells were isolated into culture for light and electron microscopy and DNA sequencing of D1–D3 of the LSU rDNA. Species of this lineage are characterized by three short and one long setae extending from each cell, the long setae from several cells joining into a common center to form large colonies, which are sometimes visible with the naked eye. Phylogenetic analyses including sequences from other parts of the world revealed segregation into three groups. Most sequences fell into two large clades, one comprising material from cold waters, whereas the other contained material from warmer waters. Strain CCMP 172 from the Strait of Georgia, Washington State, USA, formed a separate group. The warm‐water species included Chinese and Thai material and therefore probably also material from the type locality of C. socialis, Hong Kong. It is characterized by all setae being covered by spines and the setae extending from the valve at some distance from the margin. In the resting spores, both valves are ornamented with spines. The cold‐water material is characterized by three spiny and one mostly smooth long setae, and the setae extend from the valve near the margin. Both valves of the resting spore are smooth. This material is described as C. gelidus sp. nov. C. radians, described from the Baltic in 1894, is considered a synonym of C. socialis. CCMP172 is in many ways intermediate and probably constitutes a separate species. The published evidence on this globally distributed and sometimes bloom‐forming group of species indicates higher species diversity than presently thought.     

Fomitiporia tenuis and Fomitiporia aethiopica (Basidiomycetes, Hymenochaetales), two undescribed species from the Ethiopian highlands: taxonomy and phylogeny

Fomitiporia tenuis sp. nov. and Fomitiporia aethiopica sp. nov. from the Ethiopian highlands are described. Both are characterized by a resupinate habit, globose, dextrinoid basidiospores, cystidioles, and respectively scarcity or absence of hymenial setae. Fomitiporia pseudopunctata and F. robusta are reported also in the same area. The preliminary phylogenetic relationships of F. tenuis, F. aethiopica and F. pseudopunctata are inferred from parsimony analysis based on partial nuclear ribosomal large subunit (nrLSU). A preliminary key to the poroid Hymenochaetales with dextrinoid basidiospores (Fomitiporia, Phellinus s.l., Pseudoinonotus) is proposed.     

Ambispora granatensis, a new arbuscular mycorrhizal fungus, associated with Asparagus officinalis in Andalucia (Spain)

A new dimorphic fungal species in the arbuscular mycorrhiza-forming Glomeromycota, Ambispora granatensis, was isolated from an agricultural site in the province of Granada (Andalucía, Spain) growing in the rhizosphere of Asparagus officinalis. It was propagated in pot cultures with Trifolium pratense and Sorghum vulgare. The fungus also colonized Ri T-DNA transformed Daucus carota roots but did not form spores in these root organ cultures. The spores of the acaulosporoid morph are 90-150 μm diam and hyaline to white to pale yellow. They have three walls and a papillae-like rough irregular surface on the outer surface of the outer wall. The irregular surface might become difficult to detect within a few hours in lactic acid-based mountings but are clearly visible in water. The structural central wall layer of the outer wall is only 0.8-1.5 μm thick. The glomoid spores are formed singly or in small, loose spore clusters of 2-10 spores. They are hyaline to pale yellow, (25)40-70 μm diam and have a bilayered spore wall without ornamentation. Nearly full length sequences of the 18S and the ITS regions of the ribosomal gene place the new fungus in a separate clade next to Ambispora fennica and Ambispora gerdemannii. The acaulosporoid spores of the new fungus can be distinguished easily from all other spores in genus Ambispora by the conspicuous thin outer wall.     

Redescriptions of Phallodrilus parthenopaeus Pierantoni and P. obscurus Cook (Oligochaeta, Tubificidae)

The type species of Phallodrilus Pierantoni, 1902, P. parthenopaeus Pierantoni, 1902; is redescribed on the basis of new material from W Scotland. The species is characterized by its specific spermathecal and penial setae, its very slender atria, and its long spermathecal ducts. Sexually fully mature specimens of P. obscurus Cook, 1969 are described for the first time, on the basis of material from New Jersey (E USA). The new material shows that this species possesses 5 to 9 penial setae in each ventral bundle of segment XI, and that its atria are coated with a relatively thick musculature.     

The Architectonics of Colonies of Bacillus subtilis 2335

Colonies grown from vegetative Bacillus subtilis 2335 cells had a standard structure, with bacillar cells occupying the whole colony volume. At the same time, the colonies of this bacterium grown from germinated spores had an abnormal structure characterized by the location of cells in a surface layer 100–200 m thick at the colony boundary with the air. The glycocalyx of the colonies grown from spores was characterized by a wetting angle _e of 120°–160°, whereas that of the colonies grown from vegetative cells had an angle _eas low as 5°–30°. It is suggested that spores and vegetative cells follow different strategies of substrate colonization and that the architectonics of bacterial colonies is determined by the physicochemical properties of the glycocalyx.
