I don’t know much about micro

but with that hairs length and white hairs I’m inclined to L. resinaria var. ?, but the asci of this is longer a bit. Of course, we can’t be sure.

I tried to go through my keys to European species of Lachnellula

but came to no conclusion. It is impossible without spore size. You can exclude the dark colored species and the round spored species only. This has to remain a Lachnellula spec.

It is a long-stemmed Lachnellula. Unfortunately, I was not able to see any mature asci or spores, so it may be difficult to determine the species. I made preparations from two largest mushrooms and the best I was able to see about spores was that they are elliptic and biseriate (middle of the picture 4). Picture 1 shows hairs, septate and encrusted, their size about 50 × 3 microns. In picture 2, you have paraphyses (~50 × 2) and some immature asci. An isolated paraphysis and an ascus are in pictures 3 and 5 respectively. The ascus size is 60 × 6 microns.

The dried mushrooms look orange, with white underside; even the flesh is bright orange. (In my Observation 130244, there cups remained yellow after drying.)

Hairs point to Lachnellula.

Now we would need measurements and a clearer visible image of the spores. There are good keys for Lachnellula available.

Well there, Sava!

Thanks to the kindness and gentleness of Sava, it was possible to present this microscopy and thus beyond me, also the MO won with this. Thank you very much, Sava!

Let’s see if we can get a name to this.
