Hi there,
yesterday i found on ground this strange asco with stem.
The spores are 1-3 spetated and produce conidia.
I hope you can help me with the determination.

thanks in advance,
Thorben

Any chestnuts around? Clearly a Rutstroemia and obviously R. echinophila (curved spofes budding conidia). The ascus apical ring is of the Sclerotinia-type.

Hallo Zotto,
es waren Fruchtschalen von Castanea sativa vorhanden, auch mit Fruchtkörpern, aber ich hätte nicht gedacht das dieser gezeigte Asco dazu gehört. Damit dürfte das meine erste Mikroskopierte Rutstroemia sein.
Vielen dank für deine Bestimmung :)

Viele Grüße
Thorben
