me mandan el material seco de Galicia (España)
Again with a specimen of Helvella, which I believe as much in common with Helvella atra, mainly the stem. The cap however is a bit distinct from what I'm used to observe, not only because of the three saddles, but also because of the colour and texture. Is there any other species with these features?
Thanks in advance,

(17.9) 18.6 - 21.07 (21.1) × (11.1) 11.2 - 13.6 (13.7) µm
Q = (1.5) 1.52 - 1.7 ; N = 20
Me = 19.8 × 12.3 µm ; Qe = 1.6

try any key to this genus, for example: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5832953/

thanks for your suggestion and link.
However, I have a problem while trying to appy the key, as follows:
I think that is easy to reach the point 54 of the key; For clearliness I repeat the steps below. After that there are only a few taxa remaining:
H. bicolor, H. fistulosa, H. levis, H. monachella,
none of which can be selected as direct application of the key, in my opinion. The one which "seems" closer (looking at photos available in the internet) is H. monachella, but the spores of are much bigger than those of my specimen. So, what to do?
Can anyone help?
Thanks, zaca

for giving me your opinion.
Looking back to the starting point, from the title of the topic, that was my understanding, but then I decided to question to get more confidence and this now happen.
Regards from Portugal,

for increasing the percentage level of confidence. That's always nice to hearing from you and seeing some of your inexhaustible stock of beautiful photos.
Kind regards,
zaca
P.S.: Maybe, I became confused by the trilobed cap.
Quote:
"Apothecia stipitate-capitate, saddle-shaped or irregularly lobed,
1–4 cm broad, 3–12 cm high, cap margin adnate and attached
to stipe at 3–4 points; hymenium and stipe blackish with a dark
violet brown tinge (10-12F-H7-8), even or wrinkled; receptacle
surface greyish brown to black, smooth, with inconspicuous
ribs on outer surface; stipe 0.5–2.5 cm broad, naked, with 4–7
sharp-edged, partly double-edged ribs, attached at 3–4 points
to the reflexed apothecial margin greyish brown to black, paler
towards base, ribs prominent, sharp, partly anastomosing and
double-edged, with 'holes' (lacunae) between ribs, stipe chambered
inside. "
