Paraphaeosphaeria schoenoplecti sp. nov. from senescent culms of Schoenoplectus litoralis in Hong Kong

Abstract

Paraphaeosphaeria schoenoplecti sp. nov. is described and illustrated, based on collections of senescent Schoenoplectus litoralis from Hong Kong. Ascospores are 3-celled, with the central cell markedly shorter than the two end cells. The ascospores are comparatively longer than those of all other species in the genus with 3-celled ascospores and these are surrounded by a wide spreading mucilaginous sheath. Paraphaeosphaeria schoenoplecti is compared with P. concentrica, P. michotii, and P. microspora, which also consistently possess 3-celled ascospores.link_to_OA_fulltex
