摘要

Vuilleminia is a corticioid genus common in Europe whose species inhabit decaying and dead attached wood of angio-sperms. To examine the circumscription of the genus and the phylogenetic relationships among its species, we analyzed nuclear ribosomal sequence data from the ITS region and the LSU gene with maximum parsimony and Bayesian methods and also studied morphological characters. Our results challenge the notion that spore size and host specificity are critically important factors in delimiting species of Vuilleminia. A taxonomic summary of the accepted species in Vuilleminia is provided. Vuilleminia species described from the South America and Africa are demonstrated to be distinct from those of the north temperate region. Australovuilleminia coccinea gen. & sp. nov. is proposed for the taxon previously reported as V. comedens from New Zealand. Punctu-lariopsis gen. nov. is proposed for V. subglobispora described from Argentina (= Punctulariopsis subglobispora) and V.obducens from Ethiopia (= Punctulariopsis obducens). Vuilleminia is shown to be a monophyletic genus, apparently north hemispheric, and currently comprises six species. Vuilleminia together with the closely related genera Cytidia and Australovuilleminia form a well-supported clade clade) and the family name Vuilleminiaceae is resurrected to recognize this clade. Vuilleminia quercina (= Corticium quercicola) is not closely related to the other Vuilleminia species and is instead nested in a completely different clade (Corticium clade). A new genus Marchandiopsis is erected for this taxon.
