Found this asco on Racomitrium, the moss was dead or nearly so.Spores with a germslit, and it seems like it have a thin gealcoating.
14x8
13x9
11x7,5
12x7,5
12x8
11x8

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
