Carmen EchavarriHello, this is the first time I participate in the
Hello together,two weeks ago i found a hyphomycete which i can't identifie, so hopefully someone has an idea.
The fungus was growing on a lying dead culm of Bamboo in the zoo in Duisburg.
The colonies are about 3-5 mm in diameter and appear as black, "tousled" arrangements of hyphae.
Under the microscope i couldn't find any conidiophores, just dark brown, septated hyphae with warts or some kind of exudate.
The spores are brown, citriform and contain some oil droplets. The spore sizes are 9,5 - 11 x 7,5 - 9 µM.
Has anybody an idea? I checked Ellis & Ellis (microfungi on land plants) but couldn't find any match.
Best regards,
Florian
those 'conidia' look rather like the ascospores of some Chaetomium species - is it possible there are some evanescent ("vergänglich") perithecia hiding in the tousled hyphae?
best wishes
Chris
I think, that you show an interesting, not often seen species!
I agree with Chris in the genus Chaetomium.
The asci are evanescent, so that you can see them only in young stage.
With branched hairs and the spore size this should be Chaetomium elatum, a species often growing on decaying vegetable materials.
I know it from rotting straw.

Norbert
great, thank you very much! When i saw those spores for the first time i thought it might be the rest of a basiodiomycete, but the hairy colonies didn't fit to this theory. But Chaetomium with the evanescent asci fits very well!
Best Regards and have a nice day,
Florian
