White Asco on Solidago

Thorben Hülsewig, 11-10-2021 18:21

Hi there,

yesterday i found this ascomycet on dead stem of Solidago.
In Lugol the asci react red. The spores are mature 1-septated and produce little conidia (5-5,5 x 1,5-2 micrometer).
Any idea what this could be ?

best regards,
Thorben

Edit: Find it >>Calycina subherbarum
