Hymenoscyphus?
Zuidland Peter, 13-11-2022 07:04
Hello all,
Can I get some assistance towards the ID of what I think is a Hymenoscyphus on wood, possibly eucalyptus in SE Victoria, Australia.
Asci; faint Lugol +ve in the pore, Crosier +ve
Spores: 30.3-36.1 x 5.2-5.9um, many 1 septate, occasional 2 septate, budding
Paraphyces: some are capitate at the apex, many aren't

Many thanks
Peter

Re : Hymenoscyphus?
My guess is that the spores are ejected when non-septate.  I only remember Phaeohelotium geogenum with these characters, but the exciple is more prismatic (perhaps sometimes tending to angularis) and the typical geogenus is without croziers. You can also compare lasiopodium and adlasiopodium (in my folder geogenus-like, in folder "Hymenosc Cudoniella").

Re : Hymenoscyphus?
Many thanks Hans-Otto, that gives me a good direction to look at and do more work if needed.

Re : Hymenoscyphus?
Here is another look at the excipulum looking more prismatic.
I've had a look at the information in the file you suggested; P.lasiopodium is the only one that also grows on wood, I see no spores with 3 septa, otherwise it is the best fit, the others grow on leaves or grass.

Many thanks
Peter

Re : Hymenoscyphus?
Hmm, this is not really prismatic, I would say angularis, which is quite unlike H. lasiopodius. Spore septa could be a matter of overmaturity.

Re : Hymenoscyphus?
Thanks for the clarification, I will have to leave it at genus level I think.

Cheers
