Trichosphaeria notabilis on Clematis vitalba, from Mycologues Associes.

Belongs within: Diaporthomycetidae.

The Trichosphaeriaceae are a family of saprobic fungi most commonly found on wood and bark (Cannon & Kirk 2007).

Characters (from Cannon & Kirk 2007): Stromata absent, or reduced to a hyphal subiculum. Ascomata perithecial, superficial, often aggregated, ± globose, black, often thick-walled, usually setose, the ostiole papillate, periphysate; peridium composed of thick-walled angular cells, sometimes larger and more strongly pigmented towards the apex. Interascal tissue of narrow, persistent, thin-walled, true paraphyses formed from a basal meristem. Asci cylindrical, persistent, thin-walled, not fissitunicate, usually with a small J- apical ring. Ascospores variously shaped, hyaline to versicoloured, usually septate and rarely muriform, sometimes fragmenting at the septa, without germ pores, sometimes with a sheath. Anamorphs varied, hyphomycetous, with simple pigmented conidiophores and often with complex conidia.
