Type speciesFuscostagonospora sasae Kaz. Tanaka & K. Hiray.

Notes – Tanaka et al. (2015) introduced Fuscostagonospora to accommodate the bambusicolous taxon, F. sasae. Morphologically, Fuscostagonospora closely resembles Bambusicola by its narrowly fusiform ascospores and pigmented septate conidia, as well as host preferences (Dai et al. 2012, 2017). However, Fuscostagonospora is different from Bambusicola in having prominent clypeus ascomata. Phylogenetic analyses indicated that Fuscostagonospora formed as a distinct family within Pleosporales (Tanaka et al. 2015, our study). Thus, Tanaka et al. (2015) established Fuscostagonosporaceae to accomodate this genus. Fuscostagonospora is also similar to Stilbospora in having pigmented phragmosporous conidia, however Stilbospora differs from Fuscostagonospora in having acervular conidiomata filled with paraphyses and phylogenetically groups within the Diaporthales in the Sordariomycetes (Tanaka et al. 2015).
