Colpoma or Lophodermium -like on Rubus idaeus
Michel Hairaud, 11-09-2019 18:33
Michel Hairaud

Bonjour,  


J'ai récolté cette espèce sur Rubus idaeus en zone alpine pour laquelle je ne trouve pas l'identité . Asques 155_160 x 12-13  Spores 70-75 x 3 µm , paraphyses enroulées x 2µm


Merci de votre aide


Amitiés. Michel

Hi Michel
assuming that your spores go up to 100 µm, I checked my database with 50-100 x 2-3.5 µm and found nothing on Rubus, except for Stictis firabilis and S. sulfurea (= S. firabilis), which is certainly not the fungus you found.

Hallo Martin

Interesting, but I would exclude this species because of the "exceedingly slender" spores of hardly 0.75 µm width, small and narrow asci (60-70 x 4) and occurrence in Alabama.

Merci Martin and Zotto.


So would I, Zotto,  as in Tehon's description for his recombination into Dermascia rubiicola not only spores are that thin (up to 1 µm) but both ends are acute , which is not the case here.


 Is there someone studying particularly this group at the moment ?

I am not aware of anybody. Anyway, please correct the spore length in your posting.

yes it was a quick (and short) shot...
