HI,

I have here an anamorph which I find quite often on dead, decorticated wood. I were not able to find a name for it so I would be very happy if you could help me.
The anamorph is closed when dry (looking like a pyrenomycet) and opens when it is wet (looking like a discomycet). It has brown hairs and small conidia (4-5 x 1,5-2 µm) with tiny appendages (indicated by arrows).

Best wishes,

Gernot

I think you found rare Coelomycete - Dinemasporium sp.

Re:anamorph
Thank you very much, Alex! Dinemasporium seems to fit very well. With the key in the paper I come to D. affine but unfortunately the differences of D. neottiosporioides are not mentioned, except for the slightly bigger conidia.

Best wishes,

Gernot

Re:anamorph
Dear Gernot
According Mycobank - see http://www.mycobank.org/MycoTaxo.aspx - about 70 species of Dinemasporium exist. I think, you need to use additional sources. Some useful references you can find on Mycobank site:
1. open page about genus Dinemasporium using Mycobank search (first link)
2. click "more info"
3. type "Dinemasporium" in the field "Enter value to search"

I think it can help you.

Re:anamorph
Hi Alex,

you are right, there are approx. 13 names more listed by MycoBank than mentioned by Duan et. al. Unfortunately, the literature about Dinemasporium is often difficult to obtain so I think I can live with Dinemasporium sp. for the moment. Thanks again!

Best wishes,

Gernot
