Taxonomic Literature: Taxonomic notes: This variety differs from var. cichoracearum by the conidial size and by small subglobose ascospores, see below.+ascomata outer wall cells irregularly shaped, ca. 8-25 µm diam., occasionally 30 µm;+appressoria nipple-shaped, sometimes with crenulate surface, rarely somewhat lobed, one appressorium per cell or opposite or several in a series;. Braun U., Beih. Nova Hedwigia 89: 1-700 [248-252] (1987).

Biogeography: Continent: Asia-Tropical. Country or state(s): India (endemic).

Ecology: Biotroph; phytopathogenic; growing on stems or leaves, amphigenous. Host or Phorophyte Taxonomy: Goniocaulon glabrum Cass.; Goniocaulon, Compositae.

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Cleistothecioid, orbicular (small,subglobose), forming independently from the host thallus or mycelium, scattered or gregarious. Margin: External filaments present; interlaced with each other or interwoven with surrounding mycelium, mycelioid, straight, .5-2-(4) µm long, (3)-4-9-(12) µm in diameter, hyaline or pigmented (later, pale to deep brown throughout, sometimes faintly coloured or brown in the basal half and paler or hyaline in the upper half), numerous, growing all across the lower half of the ascocarp or on the upper half of the ascocarp (rarely some), smooth, thin, not ramified (mostly), septate.

Asci: 5-25 asci per ascocarp, not stipitate or distinctly stipitate (mostly), (35)-50-80-(90) µm long, (20)-25-45-(55) µm wide; dehiscence unitunicate.

Ascospores: 1–2 to c. 8 per ascus, spores 2-3-(4) per ascus, subglobose; septa absent.

Conidiomata: Present; hyphomycetous.

Conidiophores: Euoidium-type; not branched. Conidium Formation: Conidiogenous cells in chains. Conidia: Ellipsoid, ovoid, doliiform, or cylindrical; macroconidial, not branched, 24-29 µm long, 12.5-14 µm wide; aseptate.
