Taxonomic Literature: Taxonomic notes: +conidiophores foot-cells curved or somewhat flexuous, followed by 0-2 shorter cells;+ascocarp outer wall cells irregularly polygonal, ca. 8-25 µm diam.;. Braun U., Beih. Nova Hedwigia 89: 1-700 [192-193] (1987).

Biogeography: Continent: Asia-Temperate, Northern America (northeastern and central states of the USA; Canada), and Asia-Tropical. Region(s): Far Eastern Asia and China. Country or state(s): Japan; India; Florida (USA) and North Carolina (USA).

Ecology: Biotroph; phytopathogenic; growing on leaves, amphigenous. Host or Phorophyte Taxonomy: Glycine sp.; Glycine, Leguminosae-Papilionoideae.

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Cleistothecioid, orbicular, forming independently from the host thallus or mycelium, scattered, (.075)-.085-.13-(.15) mm in diam.. Margin: External filaments present (well developed, slender); interlaced with each other or interwoven with surrounding mycelium (often forming a dense web), mycelioid, straight, .5-5 µm long, (2)-3-6-(7) µm in diameter, hyaline or pigmented (yellowish, but never brown), mostly numerous (mostly), growing all across the lower half of the ascocarp, flexuose, smooth or rough, thin, not ramified or ramified, not branched (rarely) or irregular, septate.

Asci: 4-10 asci per ascocarp, not stipitate or indistinctly stipitate, (40)-50-65-(80) µm long, (25)-30-45-(50) µm wide; dehiscence unitunicate.

Ascospores: c. 4 (mostly 4-6 spores) or c. 8 per ascus, spores (3)-4-7-(8) per ascus, ellipsoid or ovoid, 16-25-(30) µm long, 9.5-15-(18) µm wide; septa absent.

Conidiomata: Present; hyphomycetous (conidiophores erect, foot cells curved or somewhat flexuouse, followed by 0-2 shorter cells).

Conidiophores: Pseudoidium-type; not branched; basal cells 19-52 µm long, 7-9 µm wide. Conidium Formation: Conidiogenous cells single. Conidia: Ellipsoid, ovoid, or cylindrical (to barrel-shaped); macroconidial, not branched, 25-50 µm long, 13-25 µm wide; aseptate.
