ADDITIONAL SPECIMENS EXAMINED: 6 collections were examined in addition to the holotype. All were from New Zealand, and included: AUCKLAND: Waitakere Ra., Chateau-Mosquito Track, on Cyathea dealbata, P. R. Johnston, 29 Apr 1982 (PDD 41874). WAIKATO: Mt Pirongia, on Cyathea dealbata, P. R. Johnston, G. J. Samuels, M. E. Lanigan, 25 Jun 1980 (PDD 41157).

Ascocarps deeply immersed, urceolate, 0.5-1.5 x 0.3-0.5 mm, opening narrow, remaining slit-like in appearance; crystalline margin resembling 2 lips along the sides. Margin in cross-section 30-70 µm wide, splitting away from hymenium when dry. Crystals forming a prominent, 30-50 µm wide layer extending to base of hymenium. Wall layer 10-25 µm wide, extending from near host surface and under subhymenium, comprising hyaline, short-celled, gelatinous, 4-7 µm diam. hyphae. Periphyses 10-25 x 3-4 µm, not branching, sparse. Paraphyses 1.5 µm diam., undifferentiated at tips, amyloid. Asci 70-105 x 4-6 µm, cap 2-5 µm thick with an indistinct, central pore, 8-spored. Spores fusiform, 13-20 x 3-4 µm, 3-septate, becoming slightly constricted at septa, hyaline.
Anamorph in vivo: Has not been found.
Characteristics in culture: Spores germinating on agar plates within 3 days. Colonies growing very slowly, pustulate, yellow or orange in colour, no aerial mycelium, sterile.

Habitat: Dead fronds of Cyathea dealbata.

Ascocarpi immersi, profunde cupulati, 0.5-1.5 x 0.3-0.5 mm, margine longitudinali, albo, in sectione transversali 30-70 µm crasso, siccus ab hymenio se abrumpens. Stratum crystallinum 30-50 µm crassum. Stratum parietis 10-25 µm crassum, hypharis 4-7 µm diam., achromis. Periphysoidea 10-25 x 3-4 µm, non ramosa. Paraphyses filiformes, simplices, in iodo caerulescentes. Asci 70-105 x 4-6 µm, apice 2-5 µm crassi, 8-spori. Sporae fusiformae, 13-20 x 3-4 µm, 3-septatae.
