Brunnipila fuscescens and long spore Brunnipila?
YI-SIOU CHEN, 09-10-2024 05:41
YI-SIOU CHENHello,

I found two species of Brunnipila in Taiwan. The sequence and morphological characteristics of PD2303_23 are similar to Brunnipila fuscescens, but the ascospores are sometimes shorter. PD2303_23 failed to identify the substrate.
According to the morphology of the apothecium and hairs of NT2405_09, it was identified as Brunnipila sp., but no Brunnipila species with filiform ascospores was found.
Detailed information and photos are organized in PDF.


Thanks for your help.


CHEN,YI-SIOU

Re : Brunnipila fuscescens and long spore Brunnipila?
Wonderful documentation! I must say that Brunnipila is a well-defined genus but inside it is very difficult. Morphological separation is more according to the substrate than to morphology which shows only slight deviations. But ITS is a good marker.

A pity that you could not identify the tree from the leaves. I attach here two ITS ML-trees.

The first is on Brunnipila, the other on Erioscyphella.

Actually, when you blast ITS of your long-spored species you will get purely Erioscyphella.

I am unaware of brown-haired members of that genus but it seems to be a similar case as in Lachnellula.

Thank you very much for the ML tree.
Placing NT2405_09 in the genus Erioscyphella seems to be a better choice. It also has the characteristics of long spores.

Re : Brunnipila fuscescens and long spore Brunnipila?
Yes, but I am not sure if there exists a species that fits. One must compare e.g. the long-spored species of Lachnum treated by Haines & Dumont: Mycotaxon 19: 1-39 (1984), though this article treats only wood-inhabiting taxa.
