摘要

A new anamorphic fungus is described based on four isolates from ascospores of Orbilia aft. luteorubella. This fungus differs from previously known Orbilia anamorphs in producing inversely pyramidal, unicellular conidia with several protuberances at their distal end. Conidia produce 1-7 prominent denticles that emerge from a node at the conidiophore apex. Conidiogenesis is holoblastic. Because phylogenetic analysis indicated greater than 90% ITS sequence similarities among the four isolates they are treated here as a single species. In the sequence analysis of the internal transcribed spacer region (ITS) these isolates and other sequences identified as O. aff. luteorubella were nested within Orbilia and formed a clade with 99% bootstrap support. This clade is separated from nematode-trapping species of Orbilia. Based on both morphological and molecular analyses, we propose a new genus, Pseudotripoconidium.
