摘要
A new coelomycetous genus, Pustulomyces, inhabiting decaying bamboo, is introduced based on morpho-molecular studies. Pustulomyces is characterized by immersed, pustule-like, acervular conidiomata, with dark ostiolar necks, enteroblastic, phialidic conidiogenous cells with a small collarette and fusiform, sigmoid, aseptate, guttulate conidia. In morphology it is similar with Bambusicola (Bambusicolaceae), but maximum-likelihood and Bayesian analyses of the combined LSU and TEF-1 alpha sequence data set shows Pustulomyces belongs in Diaporthaceae, Diaporthales. The new fungus is compared with other morphologically and phylogenetically similar genera.
