The ancestors of fungi are believed to be simple aquatic forms with flagellated spores, similar to members of the extant phylum Chytridiomycota (chytrids). Current classifications assume that chytrids form an early-diverging clade within the kingdom Fungi and imply a single loss of the spore flagellum, leading to the diversification of terrestrial fungi.(More)
We reassessed the circumscription of the cantharelloid clade and identified monophyletic groups by using nLSU, nSSU, mtSSU and RPB2 sequence data. Results agreed with earlier studies that placed the genera Cantharellus, Craterellus, Hydnum, Clavulina, Membranomyces, Multiclavula, Sistotrema, Botryobasidium and the family Ceratobasidiaceae in that clade.(More)
A phylogeny of the fungal phylum Basidiomycota is presented based on a survey of 160 taxa and five nuclear genes. Two genes, rpb2, and tef1, are presented in detail. The rpb2 gene is more variable than tef1 and recovers well-supported clades at shallow and deep taxonomic levels. The tef1 gene recovers some deep and ordinal-level relationships but with(More)
The hymenochaetoid clade is dominated by wood-decaying species previously classified in the artificial families Corticiaceae, Polyporaceae and Stereaceae. The majority of these species cause a white rot. The polypore Bridgeoporus and several corticicoid species with inconspicuous basidiomata live in association with brown-rotted wood, but their nutritional(More)
Notes on 113 fungal taxa are compiled in this paper, including 11 new genera, 89 new species, one new subspecies, three new combinations and seven reference specimens. A wide geographic and taxonomic range of fungal taxa are detailed. In the Ascomycota the new genera Angustospora (Testudinaceae), Camporesia (Xylariaceae), Clematidis, Crassiparies(More)
The current paper represents the third contribution in the Genera of Fungi series, linking the type species of fungal genera to their morphology and DNA sequence data, and, where possible, ecology. In this issue, we have focused on six genera, including macro- and microfungi, four of which the type species is epitypified. In addition, two new families(More)
A new species Ganoderma carocalcareus (Basidiomycota, Ganodermataceae) was collected on living trunk and dead stumps of Anthocleista nobilis (Gentianaceae) in waterlogged swamps in the Mbalmayo Forest Reserve, Cameroon, and identified on the basis of morphology and phylogenetic analyses inferred from mitochondrial small subunit (mtSSU) and internal(More)
One new species of Hyphodontia s.s. (Basidiomycota) is described. Hyphodontia borbonica was found on the tropical island La Réunion of the Mascarene archipelago in the Indian Ocean. It is characterized by a poroid hymenophore, a pseudodimitic hyphal system and lagenocystidia, which is a new combination in this genus. The phylogenetic analyses with ITS(More)
A new corticioid species is recognized in the genus Phanerochaete based on the material collected from the Changbaishan Nature Reserve in NE China. Phanerochaete aurantiobadia sp. nov. is characterized by an orange to reddish brown, resupinate basidiome turning coccine red upon contact with potassium hydroxide (KOH), lack of rhizomorphs and cystidia, and(More)
