Hymenoscyphus species
Nicolas VAN VOOREN, 26-11-2014 18:26
Nicolas VAN VOORENAnother collection from Corsica, on dead root of a bush (a sort of Genista). This belongs to the genus Hymenoscyphus but no idea of the species.
Apothecia Ø 1-3 mm, stipitate.
Ectal excipulum of textura prismatica, with hyphae 5–13 µm wide. Medullary excipulum of t. intricata. Asci 140–170 × 14-15 µm, with crozier, 8-spored, pars spor. ~80 µm, apical ring IKI + (bb). Paraphyses Ø 4-5 µm, with numerous but low refractive VBs. Spores fusoid, sometimes inequilateral, more rarely shoe-shaped, 21-26 (28.5) × (6) 7-8.5 (9) µm, OCI=4.5, rarely with a central septum (but not in asci).

Any suggestion?

Re : Hymenoscyphus species
Hi Nicolas 

you don't have a photo of  the apical ring in IKI?

I have no idea indeed. Do you think the spores are heteropolar? Is it possible to say for every spore which is the upper end?
