B ShelbourneCudoniella tenuispora: Distinctive macro and habit
I'm an amateur mushroom hunter. I like fungi. Sometimes I try to identify the fungi...
I know about the fungi:
Substrate: oak (probably Quercus robur). The white fruit body diameter is between 1 and 5 mm. The cups have a small stick. The fruit is dried yellow.
Spore 7.5-10,8 x 1.8-3,1 ascus 45-63 x 3.7-5.7, KI3 +, there are hairs.
Where do I look for the solution? What is your idea?
Thank you in advance.
Substrate and habit of your collection could fit Dasyscyphella nivea, a common species on this substrate but I cannot be sure from your pictures whether hairs are soft or not in the last cells.

good photos!
my first idea was also D. nivea but I think it is Lachnum brevipilosum, for two reasons:
- the asci are without croziers (well figured!)
- the hairs are rather short and I see them granulated and not narrowed above .
The last hair photo is very good, it shows them in the living state. i suggest to use onyl exceptionally staining reagents, because in L. brevipilosum characteristic strongly refractive vacuolar (VBs) guttules are typical, which are very sensitive to pressure or chemicals.
You should do photos of living paraphyses and also look for more hairs whether these drops occur in the lower part of the hairs. These VBs are responsible for reddening of the apothecia when senescent.

Thank you very much for your help and suggestions!
Sorry, Asco terms sometimes also cause problems of me. It is difficult to understand the answers as a beginner. I just heard about croziers, VBs... I have a small backlog :-)
I'm trying to find the living hair and paraphyses better. I hope to find fresh fruitbodies in the woods.
Thanks again!
best regards
Zsolt
Thanks . I had overlooked the hair tips thickness and did think there were croziers , especially in image 13.

Zotto
Thank you!
Now I know what the VB-guttules looks like, so it will be easier to look. I did not know exactly what to look for. (I'm completely new to the track..)
Zotto, you still think this mushroom can be a Lachnum brevipilosum?
Thanks again!
best regards
Zsolt
You can compare on my homepage the folder of that species:
go https://invivoveritas.de/ascomycetes-illustrations/
Then select 7f Helotiales, 8f Lachnaceae, then go to Lachnum and find brevipilosum.
Zotto
Yes, I found it in Hungary, more specifically in Debrecen (Place name: Debrecen Nagyerdö).
I have not found Hungarian data yet.
Thank you for everything: information, advice, suggestions, links!
beast regards, Zsolt
