Teratospermopsis gen. nov. for Chaetendophragmia protuberata, with a taxonomic review of Teratosperma

Abstract

Teratospermopsis is proposed as a new genus for Chaetendophragmia protuberata [= Teratosperma microsporum]. The genus has acrogenous, solitary, euseptate conidia seceding schizolytically from monoblastic, integrated, terminal, annellidic conidiogenous cells. The conidia are obclavate, smooth, and with an apical cell with a filiform appendage and a basal cell with a lateral appendage. A key and a synoptic table to six accepted Teratosperma species accompany comments on four rejected or dubious species, including T. macrosporum [= Endophragmiella macrospora comb. nov.].
