White, dark-haired on Pinus
Juuso Äikäs, 01-07-2020 16:26
Looking at a sample I took from a thin, dead and standing Pinus sylvestris trunk, I noticed small (ca. 0.4 mm) hairy ascos that I didn't see in the field. 

Initially I thought they might be Venturiocistella pini but that doesn't seem to fit. These don't have two distinct types of hairs and there was a negative iodine reaction (IKI) with the ascus pores. Also the spores are too wide. 

Spores:
(11.7) 11.9 - 14.3 (15.4) × (2.4) 2.6 - 3.1 (3.4) µm
Q = (3.8) 4.5 - 4.8 (5.4) ; N = 10
Me = 13.1 × 2.9 µm ; Qe = 4.6

Could this still maybe be something close to that?

Re : White, dark-haired on Pinus
Yes, and all hairs are smooth, unlike Venturiocistella.

An undescribed genus and species that I know for long, with an article almost finished. At the moment the folder is called Laevipila (Hyaloscyphaceae).

Coincidentally, I got today another report of that species.

Also here I would like to note the collection data.

Re : White, dark-haired on Pinus
Thank you, that's quite interesting! I checked the folder and this certainly seems to fit. I'll mail you the data a bit later.
