Käyttäjän ethancrenson tunnistukset

On a broken Red maple limb (Acer rubrum). Reddish stromata, with yellow matrix showing in the cross section. KOH pigments bright yellow to orange. I think I found one conidiospore, so I'm guessing that this is an anamorph. The spore was 1-septate.

growing in decorticated branch. Mostly Pinus strobus around

Ascospores:
(16.7) 16.72 - 17.9 (19.7) × (6.8) 6.9 - 8.7 (8.9) µm
Q = (1.9) 2 - 2.49 (2.5) ; N = 8
Me = 17.6 × 8 µm ; Qe = 2.2

Me = 62.8 × 15.8 µm ; Qe = 4

On Ostrya virginiana stump bitunicate pyrenomycete with yellow-green perithecia.
Asci 8-spored, croziers(+).
Ascospores with 1-septum and with gelatinous sheath, measured
