Gnomonia chamaemori

Gnomonia chamaemori (Gnomoniopsis chamaemori)

This species is usual inhabitant of cloudberry leaves, especially it likes petioles and leaf veins. It fruits in june, and my august collections were almost lacking of contents, since there is no detailed microstructures description (i had only pictures of them done in june earlier).


Perithecia immersed in leaf tissues, about 200 mk in diameter, with prominent neck to  100 mk long, 50 mk thick. Asci fusiform, about 30 x 9; spores fusoid, 2-celled, hyaline, near 15 x 3, some with small appendages.

Re : Gnomonia chamaemori
Dear Nina,
Nice finding !
It's the type species, you know.
You have perhaps read in Sogonov (2008) that apenndages are lacking in G. chamaemori. We can see them on yours. Is it an important feature ther ? I don't know.
Have you found it on Rubus chamaemorus or on another Rubus like idaeus ?

Re : Gnomonia chamaemori
Hi Alain,

it is from Rubus chamaemorus. Yes, i learned from Sogonov that the apendages are absent. My specimens now are lacking any hymenial structures, and i can't check this clearly now, but will look at them in june. I noticed that Monod (1983) drowing of spores with some appendages. In my pictures they were similar, but to know clear more collection is needed.
