MycoBank number: MB 830172; Index Fungorum number: IF 830172; Facesoffungi number: FoF14506
Etymology. Named after the host in Thai language, chringrid, meaning cricket.
Typus. THAILAND, Nakhon Si Thammarat Province, Khao Luang National Park, on Gryllidae, on the underside of leaves, 26 Jan. 2016, K. Tasanathai, S. Mongkolsamrit, D. Thanakitpipattana, W. Noisripoom, R. Promharn, P. Srikitikulchai & S. Wongkanoun (holotype BBH 41240, ex-type culture BCC80733).
Asexual morph. Unknown. Scant mycelium covering the host body, flattened, tomentose, white to cream. Perithecia superficial, pale cream (OAC900), ovoid to obclavate, (220 –)226 – 261(– 280) × (130 –)145 –167.5 (–170) μm. Asci cylindrical with thickened ascus apex, 8-spored, (125 –)134 –162.5 × (9.5 –)10 –12.5(–15) μm. Ascus cap rounded. Ascospores filiform, multiseptate, not disarticulating into part- spores, (68 –)70 – 83.5(– 87.5) × 4 – 5 μm.
Culture characteristics (from germinating ascospores) — Colonies on PDA slow-growing, attaining c. 1.2 cm diam after 30 d at 20 °C. Colony white cream (OAC795), cottony with high mycelial density, pigmented around the colony. Colony reverse cream yellow (OAC813). Colony on PDA did not produce any conidiogenous structures after 1 mo. Chlamydospores observed on PDA after 1 mo. Colonies on PSA slow-growing, attaining c. 0.8 cm diam after 30 d at 20 °C. Colony white cream (OAC816) with a brown clear zone at the colony edges. Colony reverse yellow brown (OAC799). Colony on PSA did not produce any conidiogenous structures after 1 mo. Chlamydospores observed after 1 mo. Colonies on SDAY/4 slow-growing, attaining c. 1.4 cm diam after 30 d at 20 °C. Colony cream (OAC815), cottony with high mycelial density. Colony reverse yellow cream (OAC814) with a brown clear zone at the colony edges. Similar to the colonies on PDA and PSA, it did not produce any conidiogenous structures after 1 mo. Chlamydospores observed after 1 mo.
