    Two new Ophiocordyceps species from Thailand, which belong to Ophiocordyceps nutans species complex and attack adult and nymph of stink bugs, are described: Ophiocordyceps asiana and O. tessaratomidarum. Molecular phylogenetic analyses of ITS and a combined sequence data of LSU, RPB1 and TEF1 revealed that these two new species are distinct from other known species in Ophiocordyceps nutans species complex. Based on the findings on morphological studies, they further support the naming of these two novel species. Ophiocordyceps asiana is parasitic on adult and nymph stink bugs, members of Coreidae and Pentatomidae which were recorded from China, Japan and Thailand, while O. tessaratomidarum is reported from Thailand for the first time and is only found as a parasite on adult stink bug, Tessaratoma papillosa (Tessaratomidae, Hemiptera). The fertile heads of O. asiana are shorter than reported for O. tessaratomidarum, and the colours of fertile heads producing teleomorph of these two species differs from each other by having strong reddish orange or light yellowish pink in O. asiana and pale yellow in O. tessaratomidarum.

    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.
