Mollisia on polypore?
Juuso Äikäs, 23-09-2021 09:01
A couple days ago I found some Mollisia(?)s growing on a dead polypore (possibly Inonotus radiatus on Alnus incana).

Asci with croziers, IKI+(bb), paraphyses with a long VB. The spores measure 10.1 - 11.4 × 3.8 - 4 µm, some (overmature?) with a septum. KOH negative.

Any ideas what this is?

Re : Mollisia on polypore?
Hmm, this requires more data. The excipulum is entirely hyaline? The VBs I do not clearly see but I assume they are there. Are the septa at the base of paraphyses numerous, i.e. the cells much shorter than the terminal cell?

I guess Leptodontidium trabinellum (Leptodontidiaceae, but still in my Pezizellaceae folder).

Re : Mollisia on polypore?
Thanks for the answer!

I'm pretty sure the excipulum is entirely hyaline. I actually found L. trabinellum last year, also on Alnus. I quickly glanced at a sample collected the same day as this at a different location, and it seemed to be the same species (on Alnus once again).


So, over all I'm fairly sure your suggestion is correct.

Re : Mollisia on polypore?
Indeed, that was at 16.IX.2020, from Porvoo. The present sample is from the another spot? I would place it in my folder ig you tell me also the collection date.
Juuso Äikäs, 24-09-2021 16:57
Re : Mollisia on polypore?
Yes, this is from another location, about 2 km from the previous one. The collection date is the same as in the first pic (21.9.2021).

Re : Mollisia on polypore?
Ah I overlooked. If you have coordinates I would paste them there.
