Maren KamkeHello,

I found a pyrenomycete on alnus sp. (maybe some other angiospermae).


The diameter is up to 0,2 mm. Spores 18-22 x 3,5 – 4,5 µm hyalin, with many guttules, 1-septate. Asci 8 spores without iodine porus reaktion, 95 x 8 µm.

Re : Pyreno on alnus sp.
Hi Maren,

quite looks like Chaetosphaeria, did you also see 3-septated spores (at maturity)? And conidia? This is important for determination.

regards,

Re : Pyreno on alnus sp.
Hi Björn,
thank you. In majority the spores are only 1-septate. I found only one bigger (33x5 µm) which was 2-septate. Conidia are hyalin (5x2 µm). The spores have appendixes at maturity.
regards
Maren

Re : Pyreno on alnus sp.
Hello again,
I suppose, I have identified this one, I found similar fruitbodies yesterday. It might be Zignoella (Chaetospharia) ovoidea.
