Re : Crocicreas
Hallo Elisabeth
ich denke das ist eine Rutstroemia. Schau mal unter R. venusta. Substrat dort Petasites- und Rosaceae-Blätter. War das gestern vom Steingletscher?

Re : Crocicreas
Merci Zotto, ja der ist von gestern.

Einverstanden, sieht eher danach aus. Gibt es von dieser Art eine Beschreibung?

Re : Crocicreas
es steht ja "aff." dabei und es ist ein schwieriges Terrain.


Rutstroemia venusta Svr?ek, ?eská Mykol. 20(1): 16 (1966)

ich habe nur eine Papierkopie. Muss die mal rausholen.

Re : Crocicreas
Hello Elisabeth and Zotto,

the article can be downloaded here. The most striking character is purple pigmentation on receptaculum and stipe. It seems to be present here aswell.


Its in Czech, Google translator handles it well, but I can transcribe it to English if necessary, also latin descr. is at the end of the article.

Re : Crocicreas
Ah, actually I had the article but with worse quality.
Surely this is not the correct name because the spores have double size. (13-20 x 5.5-7.5)

Re : Crocicreas
Curious that Enriques`s sample on Petasites? has similar homopolar but even smaller spores.

And all are montaneous collections. Maybe the substrate matters here. A pretty fungus!

Re : Crocicreas
I am not sure if all these recent samples are the same species. I believe spore size is varying among them.
