Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Cleistothecioid, orbicular, not emerging (in the mycelial felt), .08-.115 mm in diam.. Margin: External filaments present; not interlaced, mycelioid, straight, .5-1.5 µm long, 3-8 µm in diameter, pigmented (brown throughout or somewhat paler towards the apex), few or numerous, growing all across the lower half of the ascocarp, flexuose, smooth, thin, not ramified, aseptate or septate.

Asci: 3-6 asci per ascocarp, clavate (saccate), distinctly stipitate, 50-80 µm long, 30-40 µm wide; dehiscence unitunicate.

Ascospores: 1–2 to c. 4 per ascus, spores 2-4 per ascus, broadly ellipsoid or ovoid, (15)-18-25-(30) µm long, 12-17 µm wide; septa absent; wall remaining hyaline, hyaline.

Conidiomata: Present; hyphomycetous.

Conidiophores: Euoidium-type; not branched (erect, foot-cells subcylindrical, followed by 1-2 shorter cells); conidiophore cells up to 100 µm long, basal cells 30-70 µm long, 10-12 µm wide. Conidium Formation: Conidiogenous cells in chains. Conidia: Ellipsoid (primary conidia broadly cylindrical to obovoid, with rounded apex and subtruncate apex and base, secondary conidia ellipsoid-doliiform, subcylindrical, with truncate or subtruncate apex and base), obovoid, doliiform, or cylindrical; macroconidial (length/width ratio for both kinds of conidia 1.6-2.8), not branched, 20-45 µm long, 10-20 µm wide; aseptate; without distinct fibrosin body fibrosin bodies.
