Doratomyces spec.
Jan-Arne Mentken, 09-03-2017 14:40
Hello everyone,

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.

Best regards,
Jan-Arne
