Rutstoremia sur Alnus glutinosa
Patrice TANCHAUD, 28-01-2010 13:54
Bonjour,

voici un Rutstroemia que j'aurais nommé R. firma s'il n'avait pas été sur Alnus glutinosa, mais je vois l'existence de R. alni dans le DVD de Zotto, et j'ai de la peine à voir où sont les différences.
Un avis ?
Merci d'avance.

Hi Patrice

Clearly R. alni. Is this find from lowland? Now collected? Because I know it only from high altitude during autumn.

Do you have my article in SZP? I can send you a scan.

R. firma s.str. has narrower spores which are often curved, and is only on Quercus, as far as I see.

Bonjour Zotto,
es würde mich freuen, wenn ich auch einen Scan Ihres Artikels aus der SZfM bekommen könnte..
Vielen Dank, J.Trimbach. Ich finde den Pilz jedes Jahr im Alnusbusch.

Re:Rutstoremia sur Alnus glutinosa
Hello,
I've found fungi like this many times on dedicious trees, birk for instance. The species is quite common here, but the genus Quercus is very, very rare so up north, that I live.
Rustroemia firma has been my candidad for the species, because i've not found other sensible alternative ;) Lacking litterature?

Greetings from Marja
Ps. the temperature is raising here: now only -13. Yesterday morning: -27.
