The taxonomie and ecological characterisation of the clinically important heterobasiodiomycete Fugomyces cyanescens and its association with bark beetles

摘要

Anamorphic heterobasidiomycete, taxonomically highly related or identical with Fugomyces cyanescens (Basidiomycota: Microstromatales), formerly known mostly from the clinical material, was frequently found in association with nine phloemophagous barkbeetles at eleven localities in Hungary, Bulgaria and in the Mediterranean. The isolates were identified using morphological characteristics, its physiological profile and rDNA sequences and compared with the ex-type strain. The phylog-eny was studied based on LSU and ITS-rDNA analysis. The morphology and ecology of the species is discussed in relation to related taxa which occur primarily on plants (phylloplane saprobes, parasitism), but sporadically also on clinical material obtained mostly from immuno-compromised patients.
