Bonjour à tous, Marcel LECOMTE président de L'A
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.
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 ?
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.
