New species and new records of smut fungi from China

This paper deals with six species of smut fungi which were collected in the provinces Yunnan and Gansu in China. Among them, Anthracoidea yunnanensis and Entorrhiza guttiformis are new species. Sporisorium andropogonis-annulati, which is a new combination, Sporisorium montaniensis, Urocystis pseudoanemones, and Ustilago griffithsii are new records for China.     

Ustilago aldabrensis, a new species from Seychelles, and two other smut fungi on Dactyloctenium

A new smut fungus Ustilago aldabrensis on the grass Dactyloctenium ctenoides is described and illustrated from Aldabra Island in the Seychelles archipelago. It is compared with similar species known on the genus Dactyloctenium. A further two smut fungi infecting this host plant genus, U. dactyloctenii-gigantei and U. idonea are discussed. U. dactyloctenii-gigantei is reported for the first time from Nigeria on a new host plant, D. aegyptium. U. idonea is redescribed, and its nomenclature and geographical distribution are clarified. A key to smut fungi infecting species of Dactyloctenium is provided.     

Three new species of Neosporidesmium from Hainan, China

Three species of the anamorphic fungus Neosporidesmium were collected from tropical forests in Hainan province, China. N. malloti sp. nov., N. xanthophylli sp. nov. and N. antidesmae sp. nov., and occurring, respectively, on dead branches of Mallotus hookerianus, Xanthophyllum hainanense and Antidesma ghaesembilla, are described and illustrated. A key to Neosporidesmium species is provided.     

A new species of Fomitiporia (Hymenochaetaceae, Basidiomycota) from China based on morphological and molecular characters

Fomitiporia punicata sp. nov., collected from Shaanxi Province, northern China, and so far exclusively on Punica granatum (Punicaceae), is described and illustrated, and its preliminary phylogenetic relationships are inferred based on sequence data from the ribosomal ITS-5.8S regions. Fomitiporia punicata belongs to the F. robusta–F. punctata complex, but is characterized by an effused–reflexed to pileate basidioma with triquetrous to ungulate pilei, pale yellowish brown to cinnamon brown pore surface, moderately thick-walled skeletal hyphae in the context, which are partly collapsed on drying, lack of setae, presence of fusoid to subulate cystidioles, and growth on Punica. It also forms a distinct clade within Fomitiporia, and is related to some species from the temperate or Mediterranean zone of the northern hemisphere. An identification key to the species of Fomitiporia recorded in China is provided. Fomitiporia tibetica is transferred to Pseudoinonotus.     

Mnesithea thailandica a new species of Poaceae from Thailand

Mnesithea thailandica, a new species of Poaceae subtribe Rottboelliinae from Thailand, is described and illustrated.
