Phaeohelotium on Fagus grandifolia leaves

Khomenko IgorHi,

I was unable to identify this ?Phaeohelotium sp. on Fagus grandifolia dead leaves on the ground that I found in late fall near Ottawa, ON, Canada. Apothecia are 1-2mm.
Ascospores
(10.7) 12.2 - 14.8 (15.1) × (3.6) 3.8 - 4.38 (4.4) µm
Q = (2.8) 3.1 - 3.6 (3.9) ; N = 31
Me = 13.6 × 4.1 µm ; Qe = 3.3
Overmatured spores with one septum.
8-spored asci, croziers(+), IKI+b, measure
(73.7) 76.9 - 84.9 (85.1) × (7.7) 8.3 - 9 (9.5) µm ; N = 6
Me = 79.5 × 8.7 µm ;

Thanks for your help,

Re : Phaeohelotium on Fagus grandifolia leaves
Hi Igor

this reminds me a bit of your find on spruce needles, 1.X.2020, Greenbelt, but the excipulum is very different and the stalk longer there. (my "lutescens-like" folder in monticola group).

Maybe when sreening the drawings of White's good papers around 1944 one could find something.
