Nectriaceous on Polypore

Charles Aron, 22-04-2020 11:36

Hi All,

I've just noticed Ibai's post on on an asco growing on a Tyromyces. I think I found something very similar on the BMS Cornwall foray in 2018 on Tyromyces (agg.).

Perithecia were globose, minute (c100) and pallid ( no pink tints seen). Ascospores were subglobose, c4x3, 1-septate. Asci 35-40x5.

I think my specimens were a bit more mature which might account for the larger ascospores and asci.

Best wishes,

Charles.

Re : Nectriaceous on Polypore

Hi Charles,

definitely, it looks the same. Some perithecia were pallid in my collection too - I interpreted them to be young.

I will try to upload more pictures with more details.

Nice to know that someone else found this tiny fungus.

Cheers,

Ibai.

Re : Nectriaceous on Polypore

Yes, I can't have seen it in the field but must have scanned the polypore afterwards on the off chanceof finding some microfungi!

Charles.
