ELEGANTIMYCES SPORIDESMIOPSIS GEN. ET SP. NOV. ON SUBMERGED WOOD FROMHONG-KONG

A new dematiaceous hyphomycete, Elegantimyces sporidesmiopsis gen. et sp. nov., is described from decaying wood submerged in a stream in Hon g Kong. It produces predominantly 3-septate, obclavate, versicoloured, solitary conidia at the apex of the sympodially regenerating conidiop hores. The apical cell of the conidia is unique in becoming a sympodia lly proliferating conidiogenous cell producing an Idriella-like synana morph. Conidial secession in this fungus is rhexolytic. Elegantimyces is compared with Sporidesmium bifasciatum, S. tropicale and S. urceola tum which also produce Idriella-like synanamorphs.
