Helvella?
Filip Filip Fuljer, 09-05-2019 20:49
Filip Filip FuljerHello everyone,

we found one strange species from the genus Helvella, but IDK which species that should be.
Please can someone type me some ideas?
Data: 4.5.2019, alt.420mnm., Slovakia

Description:
Cup-shaped, edge of the apothecium was pubescent. Stem strongly ribbed. Whole fruitbodies were with greyish tinges.
On the same locality grew Helvella corium and Morchella esculenta, too. 
Habitat was old overgrown clay tenis court covered by young trees (Salix sp, Rhamnus frangula, Larix decidua and Betula pendula).
Microscopic features:
Spores - 15,1-17,2x10-11,5µm, elipsoid, only with one oil drop
Paraphyses - enlarged above to 4,87-6,7µm
Asci - 8-spored, uniseriate

I will be thankful for any comment or idea.

Re : Helvella?
Hello,
this is Helvella corium, even if the stipes are somewhat more robust and lacunose, and the hymenium not black (maybe covered by dead leaves?).
Check the ascus base, should be without croziers and rather slender.
Regards
Mario
