Hymenoscyphus on cone of Alnus
Stefan Jakobsson, 07-08-2022 01:57
A light-coloured Hymenoscyphus growing on a cone of Alnus incana in moist sand gives me a light headache. The disc is up to 2,2 mm wide. The scutuloid spores are (15.0)15.5-18.0(19.7) × (3.7)4.0-4.6(4.8) µm, without setulae, and the asci 95-110 × 8.2-11.4 µm. It seems to have croziers, so H. fructigenus does not look right. Also, I did not find seeds when digging for them, so not either H. seminis-alni.

Are there better alternatives?


Thanks in advance,


Stefan

Re : Hymenoscyphus on cone of Alnus
Indeed clearly with croziers. I do not remember a species fitting this. The substrate is nt recognizable from your photos, is the cone entire or broken?

Re : Hymenoscyphus on cone of Alnus
The cone is entire.
