Hymenoscyphus on Prunus cerasus old leaves
Enrique Rubio, 13-11-2012 17:09
Enrique RubioHi to all:

We have collected these fully white ascomata, very shortly stipitate, with no conspicous blackened base, up to 2 mm in diam. on petioles and veins of old Prunus cerasus leaves at 800 m of altitude.
The spores are 1-nucleate. The paraphyses have some very little refractive Vb's, The asci HAVE NOT CROZIERS and the ectal excipulum have an angularis to very broadly prismatical textura.

I think our finding is close to Hymenoscyphus immutabilis, but this species seems to be croziers at the base of the asci.

Can you help us?
Many thanks again

Re : Hymenoscyphus on Prunus cerasus old leaves
H. immutabilis deviates in croziers and absent VBs in paraphyses.

H. phyllogenus has much narrower spores.

no idea.
