Capronia
Enrique Rubio, 28-07-2025 12:34
Enrique RubioHi to everybody.

I would appreciate any ideas about this small Capronia with small pseudothecia measuring 250-300 microns in diameter, with walls that are barely rough due to the presence of dark, poorly developed protruding cells. Developed hairs are barely present or are very few in number.
The ascospores are always tri-septate, olive-coloured and generate conidia at maturity and after their expulsion from the asci.
These ascomata grew in small groups on Fagus sylvatica wood in the vicinity of Claussenomyces prasinulus apothecia, but not on them. No other fungi have been seen in the vicinity.

Many thanks in advance for your help.

Re : Capronia
I see some similarities with  Berlese's slide of Melanomma (Capronia) commonsii, but my fungus was not on any pyrenomycete at all.

Re : Capronia
Hi, Enrique!

Purely based on morphology and ecology, I think that your collection belongs in the vicinity of C. pilosella. There are various authors who report very similar ascospore measurements, and the development of the setae is known to vary. See, for example, this quote by Untereiner (1997): "ascomata occasionally bearing only dark, protruding cells or entirely lacking setae."

Best wishes,
Gernot

Re : Capronia
Dear Gernot

I believe that spores of pilosella spores are quite different, generally wider, with a higher Q and less curved. But this may just be my personal opinion.Thank you very much for your help.
It is a difficult genus!

Re : Capronia
Yes, definitely in need of a proper revision...
