Phaeohelotium??
William Slosse, 09-09-2021 20:11
William SlosseHello everyone,
on 04/09/21 I found the following asco growing on chestnut husks and surrounding litter in the Galgenbossen in Elverdinge, Belgium.
I suspect a Phaeohelotium sp..
Traces: Av 15.31x4.38µm (N=17); some tracks septated.
Asci: J-; with croziers
Paraphyses: multiseptated; sometimes forked, with (sparing) oil drops.
Possible to adjust this determination?
Regards,
William

Re : Phaeohelotium??
Maybe monticola.

Re : Phaeohelotium??
Yes, I agree.  The excipulum must be of thin-walled angularis at the flanks.

Re : Phaeohelotium??
Thx for your responce Enrique and Zotto.
Here are some pictures of the excipulum: angularis I suppose?

Yes, this is good. isodiametric thin-walled cells.

Re : Phaeohelotium??
Phaeohelotium monticola has been classified under Hymenoscyphus since 2005. Right?

Re : Phaeohelotium??
This is true, but in a paper about Phaeohelotium terrestre and related species we decided to accept Phaeohelotium (type P. monticola) as a separate genus:

Baral, H.O.; Galán, R.; Platas, G.; Tena, R. (2013). Phaeohelotium undulatum comb. nov. and Phaeoh. succineoguttulatum sp. nov., two segregates of the Discinella terrestris aggregate found under Eucalyptus in Spain: taxonomy, molecular biology, ecology and distributiom. – Mycosystema 32 (3): 386–428.
