Here is a Lachnum found on dead branches of Erica sp.
I would like too your opinion on it.
Altier (48800) - Mont Lozère - Alt.=1400m - 27/11/2024
Apos diameter = 2-2,5 cm
Asques IKI+ croziers+
Spores hyaline with very small gutulles, 9,9 - 11,9 × 2,8 - 3,7 µm
Q = 2,8 - 3,9 ; N = 35
Q = 2,8 - 3,9 ; N = 35
Marginal hairs 100-500µm long.
Any suggestion ?

Re : Lachnum sp.
What is the apo diameter? sorry, I overlooked, but I correct to 2-2.5 mm.
500 µm long hairs is impossible, I would believe 100-150.
This sounds like Lachnum callunae which I am going to describe. See my folder.
Any photos of the hairs?
Are the twigs corticated? I would appreciate coordinates.
The species is lnown from planar regions in the north, a bit different from yours.

My Answers to Zotto in PM.
Of course apos diameter is 2-2,5 mm and Hairs are 100-150 µm long.

Re : Lachnum sp.
This is fine, looks like in L. virgineum. The difference to that species is mainly in spore width.
