Capitotricha sur poaceae
Andgelo Mombert, 31-07-2018 19:34
Andgelo MombertBonsoir,

Sur feuilles mortes de poacées, en zone subalpine (1700 m d'alt.).

Ascospores : 14-19 x 2-2,5 µm, fusoïdes, courbées, contenant des gouttelettes, hyalines, lisses.
Asques : 50-60 x 5,5-6,5 µm, cylindriques, inoperculés, à sommet amyloïde, avec crochets, contenant huit spores bisériées.
Paraphyses : de 2,5-3 µm de large, lancéolées, dépassant les asques de 15 µm, hyalines.
Poils : larges de 4-5 µm, capités, septées, verruqueux, à sommet couvert de cristaux.

On est proche de Capitotricha brevipila mais les spores sont grandes...

Les cellules semblent mortes (?).

Merci d'avance !

Andgelo

Re : Capitotricha sur poaceae
This is extremely interesting. Have you an idea which grass it coudl be?

Indeed I also doubt that it is C. phragmiticola/brevipila (ined.) which I want to describe since a long time.  There might actually exist more species. Regrettably I do not have a sequence of phragmiticola, but yours seems not sparse and should be tested. Would you mind sending me your sample? I would have a look as well as sending a portion to UNITE for DNA.

Dear Andgelo
I just saw that the pics I downloaded are very small. If you could send them to me in larger size I would much appreciate this. There is no scale for them?

Could you please find out coordinates or otherwise tell me the place? you wrote 1800 m on the label but 1700 m in the forum.
