Microglossum rufescens?

Karl Soler Kinnerbäck, 09-11-2022 15:11

Spores 14-15(-16) x 3,5-5. With 2-4 guttules. Asci 70-90 x (6-)7-8. Ascocarps first pale-olivaceous, later brown-olivaceous. Rather long-stemmed. Turning black when dried.

I used the key to green Microglossum species by Kucera et.al 2017 and thought that M. rufescens was the closest, also after reading the description in Sylviane & Moingeon 2004.

Anyone with experience of this species who can confirm or reject?

Found in central Sweden, on unfertilized, calcerous grassland close to the Baltic sea shore, 2022-09-22.
