Hymenoscyphus fructigenus on Acer?
Juuso Äikäs, 08-09-2020 21:52
I have previously found H. fructigenus growing on an old acorn and read it grows on Corylus nuts as well. But can it also grow on samaras of Acer platanoides? The apos are pretty tough and redden on bruising. 

Spores:

(18.8) 19.6 - 23.3 (23.9) × (3.9) 4.1 - 4.5 (4.6) µm
Q = (4.3) 4.5 - 5.2 (5.3) ; N = 10
Me = 21.3 × 4.3 µm ; Qe = 4.9

Yes of course it can. But nobody knows if it is genetically all the same. At least on Carpinus seeds occurs a different species.

Re : Hymenoscyphus fructigenus on Acer?
Ok then, good to know. It has a wider range of hosts than I previously thought.

Re : Hymenoscyphus fructigenus on Acer?
I noticed I have a folder for Acer with some drawings. There are now also your pics.

The variation within Quercus is high, I have there a collection that is surely not conspecific with others on Quercus because of the broad spores with low lipid content.
