Re : Hymenoscyphus on branch of malus
Hi ismail

All elements except for two spores (e.g. the lower right) are dead, so I cannot easily give a name.

Hymenoscyphus seems correct. Perhaps you need to compare H. conscriptus which is typically on Salix wood/bark, although the spores sound a bit too wide.


How is the apothecium diameter? Did you look for the ascus base (croziers)?

Re : Hymenoscyphus on branch of malus
O.k., croziers are clearly absent, which excludes H. conscriptus and also H. calyculus and H. subferrugineus which all have croziers.

The only idea I have is H, vitigenus, but a clear idea of this I also do not have.

Did you gain a sequence of this sample?
