Hi,

Yes was thinking of that genus, but was not sure.

the whole fruit body have setae.
there is a key i see, but is it many species who has moss as substrate?

Re : Asco on racomitrium

Hello Robin,


maybe C. ligniaria?


The moss is fully bleached - maybe this has a reason. Perhaps manure or urine of an animal?


Coniochaeta-species usually grow on dung or wood, as nutrient-loving saprobes. Moss as substrate is unusual, but as the species are quite polyphageous perhaps not a wonder - and for me it is unlikely that there are species of this genus that are (exclusively) bryophilous.


Best, Lothar
