, veil grey to grey-brown, all tissues grey in KOH.
This was the best match from Champions du Suisse tome 5, and it looks fairly good there. That source mentions the grey veil. I couldn’t get an id with Funga Nordica (couldn’t find my way through the Telamonia keys there), but this species is listed there. After going back to it with this species name, they have a split there, with C. bovinus having an off-white veil and fairly smooth cap, and a C. fuscobovinus that has a fibrillose cap, and the grey veil. From there it seems that C. fuscobovinus is a better name for these. But I’m going to default to the more local source the for the id for now (until I find the other C. bovinus…).
The micro-shot is of spores from the veil at 1000x in KOH. The spores are ellipsoid, brown, warted. The apr. size is 10 × 7 um.
The spores actually work better in Funga Nordica with C. fuscobovinus, where they are wider than C. bovinus. But this is only a 0.5 um different, so not a big thing.
The spores size listed in Champions du Suisse for C. bovinus is much smaller than this, but in the notes there is mentioned large spored variations. Not sure, perhaps some of these variations are separated as C. fuscobovinus.
