Additional specimens examined: 9 collections were examined in addition to the holotype. All were from New Zealand, and included: AUCKLAND: Waitakere Ra., Sharps Bush, on Dracophyllum latifolium A. Cunn., P. R. Johnston, G. J. Samuels, 3 Mar 1980 (PDD 41892); Waitakere Ra., Karamatura Stream, on Cyathea medullaris, P. R. Johnston, E. Horak, B. Segedin, 24 Jun 1981 (PDD 41896). WAIKATO: Ngaruawahia, Hakarimata Reserve, on unidentified herbaceous host, P. R. Johnston, G. J. Samuels, J. M. Dingley, 28 Jan 1981 (PDD 41898).

Ascocarps deeply immersed, urceolate, round, 0.4-0.8 mm diam., semi-erumpent, crystalline margin entire, greyish; surrounded by subiculum comprising fine, orange-brown coloured hyphae. Margin in cross-section 60-100 µm wide. Crystals forming a 40-75 µm wide layer at top of margin. Wall layer 5-10 µm wide, extending from top of margin and under subhymenium, comprising pale brown, thin walled, 1.5-3 µm diam. hyphae. Wall surrounded by 20-50 µm wide stromatic layer, comprising dark brown, thick walled, irregularly oriented hyphae. Periphyses 30-60 x 2-2.5 µm, branching. Subhymenium faintly amyloid. Paraphyses not differentiated at tips, 1.5-2 µm diam., nonamyloid. Asci 420-520 x 5-7 µm, cap 5-7.5 µm thick, 8-spored. Spores 350-600(-800) x 1.5-2.5 µm, cells 4-6 µm long, sometimes showing an indistinct, gelatinous sheath.
Anamorph in vivo: Pycnidia globose, 60-100 µm diam., immersed, appearing to open by an irregular split in wall layer. Walls 25-30 µm thick, com rising dark brown, thin-walled, tangled hyphae, forming a more or less pseudoparenchymatous tissue. Conidiogenous cells arising from inner wall layers, cylindric, 4-10 x 1.5-2 µm, hyaline, phialidic, solitary or rarely on short, unbranching conidiophores, apertures apical, or lateral and immediately below transverse septa. Conidia acropleurogenous, cylindric, 5.5-10 x 0.8-1 µm, ends rounded, nonseptate, hyaline.
Characteristics in culture: Ascospores germinating on agar plates within 24 h, forming colonies on OA 3-4 cm diam. after 8 weeks. Aerial mycelium dense, cottony, white. Pycnidia globose, 150-280 µm diam., separate, scattered over agar surface, dark walled, opening by an irregular split in wall. Walls 30-50 µm thick, comprising partly gelatinised, tangled, 1.5-3 µm diam. hyphae. Inner few layers of cells hyaline, outer layers with dark brown walls, although they are often paler in lower half of pycnidium. Conidiogenous layer is the same as that found in vivo, but the conidiogenous cells are more often held on the short, unbranching conidiophores.

Habitat: Common on the dead leaves of plants with large, tough, strap-like leaves. Also found rarely on Cyathea medullaris.

Ascocarpi immersi, profunde cupulati, 0.4-0.8 mm diam., margine integro, griseo, in sectione transversali 60-100 µm crasso. Stratum crystallinum 40-75 µm crassum. Stratum parietis et stroma 30-60 µm crassa, hypharis 1.5-3 µm diam., brunneis. Periphysoidea 30-60 x 2-2.5 µm, non ramosa. Subhymenium in iodo caerulescentes. Paraphyses filiformes, simplices, in iodo caerulescentes. Asci 420-520 x 5-7 µm, apice 5-7.5 µm crassi, 8-spori. Sporae 350-600(-800) x 1.5-2.5 µm, cellulis 4-6 µm longis. Status conidialis: Coleophoma-similis.
Holotypus: PDD 41899 ex Freycinetia baueriana Endlicher ssp. banksii (A. Cunn.) B. C. Stone.

Notes: See notes under S. asteliae.
Etymology: subiculata; refers to fine subiculum surrouding ascocarp.

Holotype: New Zealand: AUCKLAND: Waitakere Ra., Cascades Track, on Freycinetia baueriana ssp. banksii, P. R. Johnston, G. J. Samuels, 9 Mar 1981 (PDD 41899).
