some days ago I found a Doratomyces on dead wood, which shows both verrucose and smooth spores. At first I thought the verrucose spores would be the Echinobotryum state, so it would have been Doratomyces stemonitis, but they are way too small (6-7,5 x 4-4,5 µm instead of 9-14 x 5-8 µm) and also look a bit different. So the question is: Are the smooth spores young conidia, which will get verrucose as well later on (-> Doratomyces nanus) or what else can it be? Thanks for any help!
Kind regards,
Jan-Arne

Re : Doratomyces spec.
Hello Jan.
I am not a great specialist of these mushrooms, but I think it is a Cephalotrichum (Doratomyces). I had the opportunity to find Cephalotrichum stemonitis with the Echinobotryum state but the spores measurements are more important. Your fungus is probably another species.
Michel.

Re : Doratomyces spec.
Hi Michel,
thanks for your response. I guess you are right. The Echinobotryum State looks really different in size and shape. So D. nanus is the best option so far, though the smooth spores are still irritating.
