Peninsula, where it was collected on decaying plant debris, seemingly on sandy soil. Its thallus appears whitish (but may have been discoloured by age) and encrusts the substrate by forming coalescing irregular granules.

Excipular hyphae are moderately gelatinized and have narrowly to widely ellipsoidal cell lumina that become up to c. 20 μm long and are strongly constricted at the septa. The hypothecium and medulla are poorly differentiated and form a strongly developed cushion of hyphae. The hymenium is 35–40 μm thick, containing clavate, stout (3–4 μm wide at half their length), unbranched paraphyses with apices up to 6 μm wide and clavate asci with 8 or more helically arranged ascospores (possibly 12 or 16, difficult to count; our highest count is 14 clearly visible ascospores). Ascospores are acicular 27–41 × 2.0–2.5 μm (28–41 × 2.0 μm according to
