I suggest Helvella fusca Gillet with such color.
cheers

François, thanks for your version!

Tomás, this discomycetes grown in mixed forest with Querqus, Acer, Sambucus and Corylus.

Hi to everybody
I suggest youngs Helvella crispa

in Helvella fusca normally, the hymenium is exposed (outside) and saddle-shaped (expecially when young); the sterile surface is traversed by large veins; finally is exclusive of Populus in spring often with Helvella leucopus.


Best, Carlo

Hi Masha!

Of course it is H. crispa! I agree with Carlo. I would like to add Carlo's comments with few more info: The hymenial colour in these two (H. crispa and H. fusca) is also constantly different. H. crispa always has whitish to creamy((greyish)) hymenia, while H. fusca has fulvous-yellow to foxy-ochre to fuscous hym. from beginning. This is because H. fusca has paraphyses that contain yellowish pigments. H. crispa's paraphyses are hyaline - like in your microphoto. :-) Also, pileal margin when fruitbody is fully mature is still inrolled to almost even in H. crispa, while H. fusca has exrolled margin when fully ripe.

Average appearance of H. fusca in SE Europe is attached below

Ecology is also sharply different as Carlo already mentioned.

However, outside Europe, there is few superficially very similar Helvellas that could be very probably distingushed from H. crispa at specific level (e.g. in North America and China/Central Asia).

Masha, can you tell me just roughly geographical position of your collection?

Cheers,
Neven

Sans aucun doute H. crispa

Salutations

Neven, many thanks for your full answer about my Helvella.

My material was collected in north-western part of Ukraine near the Polish border in Shatski NNP.

René, Thank you!

Masha

 

You're welcome Maša!

Yes, such area should be really free from Helvella crispa like surprises as far as I know!

Cordially,
Neven
