Hymenoscyphus vitigenus?
Hello!
Specimens growing on indeterminate leaves in a mixed forest of Quercus robur, Alnus sp., Populus sp., and other riparian vegetation.
Positive reaction of the asci apex in Lugol's iodine.
I haven't obtained any free spore print, but I believe I observed mature spores, crusted in the center, with a septum.
(15.2) 16.3 - 20.3 (21.5) × (4.3) 4.8 - 5.7 (6.2) µm
Q = (2.9) 3 - 4 (4.5) ; N = 19
Me = 18.5 × 5.2 µm ; Qe = 3.6

Re : ID Help Hymenoscyphus
My guess is H. caudatus. The spores are only faintly scutuloid which is possible in this variable species. H. vitigenus is unclarified, it is heterogeneous in the type of the perhaps identical H. hyalopes (see my paper on H. menthae (2015, Ascomycete.org, 7 (6) : 255-287).

Re : ID Help Hymenoscyphus
At first I thought it was H. caudatus, but I followed a key that led me to H. vitigenus, and now I have my doubts. Thank you very much for your help.
