Hymenoscyphus aff fucatus? H-
Viktorie Halasu, 10-10-2020 18:05
Viktorie HalasuHello,

can I call this H. fucatus H-, or are the spores still too short? Only one spore had 2 very short setulae, others without. VBs medium refractive. On Rubus fruticosus stem. 
edit: host is R. caesius

Thank you in advance.

Re : Hymenoscyphus aff fucatus? H-
Very difficult to answer! I would still consider H. scutula, despite the absence of long setulae. A difficult case, particularly since we know almost nothing about genetics in H. scutula.

Oh, I must correct myself, I had a wrong remembering, here is an ITS tree showing the true scutula in green and some other genotypes.

Dear Zotto,
thank you very much. Is this collection different enough that it would be useful to sequence it?
