On bur oak - Quercus macrocarpa overwintered leaf tiny green fungi. Fruitbodies cylindrical 0.2-0.24x0.13-0.15mm.
Under a microscope they look like cup fungi.
Asci cylindrical, 8-spored, ?IKI+b, 130-163x6-8um.
Ascospores filiform, very long, probably with 7-septa, measured
*(125.5) 127.6 - 130 (133.7) × (1.6) 1.8 - 1.9 (2) µm
Q = (65.1) 65.8 - 76.3 (78.2) ; N = 6
Me = 129.1 × 1.8 µm ; Qe = 70.9

Paraphyses enlarge at the apex, spatulate with highly refracting VBs, 3.6-6.1um at the apex.
Ass. Ophiognomonia setacea.
