Very small global ascomycete, hyalin, smooth spores. Any ideas?
S. Rebecca, 22-08-2021 15:19
I found this tiny ascomycete in a bank of earth close to a stream in the Austrian Alps where I live (1200m). I have been asking around, but do not have any good leads yet. I was able to collect about 8 specimens and they do have a smell but hard to describe. Maybe a little like metal? I hope someone recognizes something.

Due to the spores being translucent, I thought maybe Orbilia, but someone said absolutely not Orbilia. Possibly something related to hypogae?

The specimens have a hole in them.
J- (Lugol)
Spore size 18-22µm
Ascus = 8 spores
Each spore has a hull or sack and you can see them split.

I can add microscopic features if you tell me what to look for. 
Thanks, -Rebecca

Dear Rebecca,

as I have posted in a different forum a short while ago, this looks like Stephensia (Hydnocystis) bombycina (compare to https://www.nahuby.sk/obrazok_detail.php?obrazok_id=588562).

Best wishes,
Gernot

Hi Gernot, Rebecca

Some time has passed since that find. I now think, I might have not identified it correctly.

Stephensia colomboi might be better name for our collections. S./H. bombycina is a larger, hypogeic species, whereas colomboi is smaller, often only partially buried. Both seem to have an unpleasant odour.

Re : Very small global ascomycete, hyalin, smooth spores. Any ideas?
Thanks for this hint, Adam. I don't have the original description of S. colomboi but I compared with Sarasini et al. (Funghi Ipogei Lariani), where it is mentioned that S. colomboi should have an "insignificant" odour, wheres S. bombycina is said to smell much more intensely (like fried onions or boiled cabbage). Macroscopically this collection shows more similarities with S. colomboi, so I concur with you that this is likely the better name.

Best wishes,
Gernot
