Orbilia crenatomarginata

Species developing on wet, decaying decorticated wood, with sessile disc- or saucer-shaped apothecia 0.4–1.3 mm in diameter, translucent, whitish with greyish tones and slight violaceous or pinkish tints, and a crenulate margin.

Medullary and ectal excipula of textura globulosa (typical of the genus Orbilia), composed of hyaline, moderately thick-walled cells.

Asci cylindrical, 8-spored, measuring 23–37 µm long by 3–4 µm wide, with irregular spore arrangement, surrounded by a congophilic gel sheath over their entire surface.

Paraphyses sparse, filiform, only slightly widened at the apex, non-septate, 2–3 µm wide.

Ascospores sigmoid to helicoid, smooth, hyaline, very thin-walled, measuring 6–9 µm long by 0.6–1 µm wide, with homogeneous contents, lacking oil droplets.
