A Helvella from Iran
Reza Shaian, 24-01-2013 10:12
Dear friends, I collected a Helvella specimen that is similar to H. ephippium, but is greater and stipe is white to cream. H. compressa also is similar but it is a N. Ameircan species. Waht is your idea?

Cap up to 2 cm, irregularly lobed; inrolled; free from stipe, upper surface brown, undersurface cream to pale brown, pubescent,

Stipe up to 5 cm long, up to 1 cm wide, white to cream.


Spores 19-22 x 11.5-14.5, elliptical, smooth; with one large oil droplet.


Paraphyses with subclavate to clavate apices

Re : A Helvella from Iran
Hello.
Difficult to say something with only one specimen... Three species could be investigated: Helvella latispora, H. albella and H. elastica (although the latter is less obvious).
More data about the cells on the outer surface will be useful, and also on the ecology.
Is there a brown pigment into the paraphyses?

Re : A Helvella from Iran
I agree with Nicolas, we need more data to help you. I would add another species, Helvella stevensii. If it is pubescent (i.e., hyphal fascicles more than 50 micrometers), I do not think it is H. elastica, and by the apothecium colour it could not be H. albella or H. compressa (the latter endemic to the west coast of North America ). So I think it could be between H. latispora and H. stevensii ... I recommend also check if it have dextrinoid tissues...

Best,
Fidel

Re : A Helvella from Iran
Nicolas have right, it is in Sectio Elasticae, and Fidel correctly excluded H. elastica for the pubescent undersurface. I add that the margin in some points seems slightly inrolled (this should be much more evident in the young ascomata), excluding once again H. elastica.
If we believe in the spore size given by Boudier when describing H. latispora, your collection should be H. stevensii, as far as we consider separated these last two.
