Index Fungorum number: IF 807748; Faces of fungi number: FoF 00064.

Saprobic on dead leaves of Syzygium cumini. Conidiomata acervulus, 140–175 ( = 152) μm diam., superficial to semi-immersed, separate, dark olivaceous to black; wall 3–7 layered, 30–44 ( = 36) μm wide, pale to moderately dark brown, with a well-developed pseudoparenchymatous layer of cells of textura angularis at the base that becomes thinner at the margin of conidiomata. Conidiophores 24–44 × 3–4 ( = 33 × 4) μm, septate, branched, compactly arranged above the pseudoparenchymatous tissue layer, hyaline, cylindrical, tapered towards the apex, smooth. Conidiogenous cells enteroblastic, phialidic with a flared, conspicuous collarette with a serrate margin, rarely percurrently proliferating, discrete or integrated, cylindrical to vase-like, tapered towards the apex. Conidia fusiform to oval or obovoid, with a rounded apex and narrowly truncate to pointed base, 9–15 × 5–6 (x = 11 × 5) μm, length/width ratio 2.2:1, light brown to olivaceous-brown, thick-walled, smooth-walled, with one-to-many oil droplets.

Colony characters – Colonies on PDA medium to dark brown from above and reverse, with medium to dense surface mycelium, flat, irregular to rhizoidal, with undulate to lobate margin, attaining a diam. of 25 mm in 7 days at 27 ̊C, sporulating after 14 days.

Material examined – Thailand, Chiang Rai: Mae Fah Luang University campus, on dead leaves of Syzygium cumini, 21 March 2012, leg. N.Tangthirasunun (MFLU 13-0255, holotype, PDD 105206, isotype); ex-type living culture = MFLUCC 12-0298 = NTCL 052-1 =ICMP 20057

GenBank accession numbers – ITS = KJ021933, nuLSU = KJ021935, nuSSU = KJ021934, TUB = KJ021936.

Notes – Differs from G. uvicola by its smaller conidiomata and larger conidia and in its nuLSU gene sequence.
