Type species – Stilbospora macrosperma Pers.

Notes – The type species Stilbospora macrosperma was epitypified by Voglmayr & Jaklitsch (2014). Prosthecium (the asexual morph) includes opportunistic and moderately phytopathogenic taxa, which are responsible for the branch dieback or twig blight in several overwintered plants (Voglmayr & Jaklitsch 2008). Some species of Prosthecium were also recorded from corticated and dead branches of the same plants (Voglmayr & Jaklitsch 2014). In this entry, we illustrated the sexual morph of Stilbospora macrosperma.
