Original article


A new hyphomycetous fungus, Micronematobotrys verrucosus, isolated as an endophyte from Quercus liaotungensis and Ulmus macrocarpa in the Dongling Mountain of Beijing is described as a new monotypic genus represented by M. verrucosus. This new species differs morphologically from Botrytis-like fungi and other similar genera in possessing micronematous conidiophores and colored verrucose conidia. The phylogenetic relationships of Micronematobotrys among sexual ascomycetes are examined based on 18S and 28S rDNA sequence data using maximum parsimony and Bayesian methods. The phylogenetic analyses suggest that M. verrucosus is a member of Pyronemataceae in Pezizales.
