Notes – Members of the genus are saprobes or mild pathogens in overwintered plants such as Acer sp. (Senanayake et al. 2018). The genus has both sexual and asexual morphs and Stegonsporium shows a high similarity with Stilbospora (Voglmayr & Jaklitsch 2008). Stegonsporium has pyriform conidia which bear 2–7 transverse and 1–3 longitudinal distosepta. In addition the ascospores of the genus are distoseptate. These two significant characters separate Stegonsporium from Stilbospora (Voglmayr & Jaklitsch 2008).

 

Type species: Stegonsporium pyriforme (Hoffm.) Corda.

Other accepted species: Species Fungorum – search Stegonsporium.
