Hello, I'm new at this forum and like to ask you of you can help me. On hare dung I found a black asco  who was very hairy. Ik looked at the book of Doveri and think it can be a chaetomium? In the Doveri are a cpuple of them but not with the kind of sporen I found. At the end of the spores there are Appendices. Maybe I'm thinking wrong and that's why I hope you can help me with it.

Dinemasporium on dung
Dear Hannie Wijers,

this is not a species of the genus Chaetomium.

The limited information are more likely to the genus Dinemasporium, maybe Dinemasporium fimeti Plowr. & W. Phillips 1876.

Dinemasporium is the anamorphic stage of the genus Phomatospora. Phomatospora coprophila Richardson 1972 is coprophilous and probably the best known species of dung.

I do not know whether the two taxa are genetically connected. Likewise gramincole species are possible.

The size and number of septa of the conidia should add here yet.

Yan

The genus Phomatospora and its anamorph stages are not yet sufficiently investigated and verified genetically. Standard literature, for example, Sutton and Ellis & Ellis give only a rough outline, but no further help. In addition, we need new studies to see whether the species Pseudolachnea has a permission. Collections on manure, such as those of you who are often found. I know a lot of samples on the dung of rabbits and hares. If you want to work seriously and accept the above reasons, would be the correct name of your collection: "Dinemasporium-like".

Re : chaetomium
Hi Hannie,

this is no Chaetomium, but maybe Pseudolachnea hispidula.

Re : chaetomium
Wow, what a quick answer this is. I didnt' measure the length of the conidis. I'll look one of these days if there is new material in the dung. I'll look for thes suggestions bothe of you said. Does any of you know if thers is some lecture about these genus?
Yan and Norbert thanks a lot.

Re : chaetomium
Thank you. I took a quick look at this moment, tomorrow I want to look further on the web.

Re : chaetomium

I could find one asco on the dung, the last on. I took some pictures. Ik hope I took the right ones. I think the The size of the conidia is 9,9-13,2*2,4-3,3 µm and number of septa is 1.
