    Recent collections of bird's nest fungi (i.e. Crucibulum, Cyathus, Mycocalia, Nidula, and Nidularia species) in northern Thailand resulted in the discovery of a new species of Cyathus, herein described as C. subglobisporus. This species is distinct by a combination of ivory-coloured fruiting bodies covered with shaggy hairs, plications on the inner surface of the peridium and subglobose basidiospores. Phylogenetic analyses based on ITS and LSU ribosomal DNA sequences using neighbour-joining, maximum likelihood and weighted maximum parsimony support Cyathus subglobisporus as a distinct species and sister to a clade containing C. annulatus, C. renweii and C. stercoreus in the Striatum group. © 2008 Nationaal Herbarium Nederland Centraalbureau voor Schimmelcultures.

    Phylogenetic relationships within the genus Cyathus (bird's nest fungi) were investigated with neighbor joining, maximum likelihood, weighted maximum parsimony and MrBayes analyses of ITS and LSU ribosomal DNA sequences datasets. Twenty-two taxa of Cyathus were used in the analyses based primarily on type and authentic specimens. The current infrageneric classification system of Brodie recognizes seven infrageneric groups based on morphological characters, including peridium plications and variations in peridium hair anatomy, peridiole structure and fruit-body color. These groups are not supported by molecular data. Instead the ITS and LSU datasets support recognition of three infrageneric groups herein named the ollum, pallidum and striatum groups. Morphological characters useful in distinguishing these groups include basidiospore size, fruit-body coloration and peridium anatomy. Cyathus africanus var. latisporus is considered a synonym of Cyathus jiayuguanensis, and a new combination Cyathus lanatus (Brodie) R.L. Zhao is proposed based on morphological and molecular data. © 2007 by The Mycological Society of America.

    Proposed synonyms in Cyathus

    Based on the morphological analyses of 48 taxa of Cyathus, including 30 type specimens, three Cyathus species were found to represent synonyms of existing species. Cyathus cheliensis, C. gansuensis and C. megasporus are herein accepted as synonyms of C. limbatus, C. pygmaeus and C. poeppigii, respectively. The latter three species are redescribed and illustrated.
