Colacogloea: a new genus in the auricularioid Heterobasidiomycetes

摘要

A new genus,Colacogloea, is described in the auricularioid Heterobasidiomycetes having simple septal pores. The genus is based onPlatygloea peniophorae, a mycoparasite of some Aphyllophorales species. It is a segregate from the heterogeneousPlatygloeas.l. The most important distinguishing features ofColacogloeaare (i) the frequently simultaneous presence of basidial and conidial stages, (ii) a dimorphic life cycle including a yeast phase, (iii) mycoparasitism by colacosomes, (iv) simple septal pores with rounded margins, but without associated electron-opaque bandings and globules, and (v) aseptate basidiospores.Key words: Heterobasidiomycetes,Platygloea,Colacogloea peniophorae, mycoparasitism, colacosomes.
