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

H. immutabilis deviates in croziers and absent VBs in paraphyses.

H. phyllogenus has much narrower spores.

no idea.
