Conidiogenous cells holoblastic, hyaline, cylindrical to ellipsoidal, smooth. Conidia hyaline, aseptate, cylindrical to cylindro-clavate, thin-walled.

Notes: Botryobambusa is introduced as a monotypic genus for B. fusicoccum which is characterized by multiloculate ascostromata, clavate, short pedicellate, fissitunicate asci and velvety, selleckchem thick-walled, hyaline, aseptate, sheathed ascospores. It is so far only known from bamboo. The see more ascomata are tightly clustered under the bamboo host surface and can be considered as ascostromatic in a broad sense. This is obvious in culture where the pycnidia are clearly stromatic. The genus can be distinguished from the closely similar Botryosphaeria by its smaller asci, aseptate, velvety, hyaline, sheathed ascospores and Fusicoccum-like asexual stage with large conidia. Phylogenetically, these two genera are markedly distinguished. Generic type: Botryobambusa fusicoccum R. Phookamsak, J.K. Liu & K.D. Hyde Botryobambusa fusicoccum R. Phookamsak, J.K. Liu & K.D.
