Dear Gernot,

thank you very much, that looks very promising!
May be Jacques can confirm this :-)

best regards,
Andreas

Hallo Gernot,

wieso kennst Du diese Art eigentlich?
Ich wollte mal etwas darüber recherchieren, aber die Art ist noch nicht mal in unserem TaxRef-Liste für Deutschland enthalten - scheint also neu für Deutschland zu sein?!

beste Grüße,
Andreas

Hi Andreas and Gernot,
this would be my guess too, around H. stuppea.If you read the Mycologia paper you will see that the delimitation of these species is not fully resolved.
Good luck!
Jacques

Dear Jacques,

thanks a lot!
Not fully resolved means, that it is not certain that the european collections are identical to the american ones. But the european collections are identical one to each other, isn't it?

Is this a rare species? I don't find anything in german language on that species ....

best regards,
Andreas

It is basically an American taxon, rarely recorded. The few European collections are very similar to the type but exhibit some variations between them especially as to ascospore morphology and also slightly deviate from the American material. A situation we are unfortunately familiar with!

Hi Andreas,

just a few weeks ago we had a collection of a "typical" H. stuppea, i.e. one that fits the description in the Mycologia article quite well. Unfortunately I won't have access to the photos of this collection until next week so I can't show them right now.

And a few years back I found a species that came close to H. stuppea but had deviating ascospores. That was the collection that intruduced me to this intricate group. :-)

Best wishes,
Gernot
