Additional specimen examined: New Zealand: AUCKLAND: Waitakere Ra., Piha, Kitekite Track, on Astelia trinervia, P. R. Johnston, 16 Jun 1982 (PDD 42781).

Ascocarps deeply immersed, urceolate, not erumpent, 0.3-0.6 mm diam., round; crystalline margin entire, white, eroding, with the surrounding host surface becoming covered with scattered, loose crystals. Margin in cross-section 80-120 µm wide. Crystals forming a 50-80 µm wide layer extending most of way down ascocarp margin. Wall layer up to 40-45 µm wide, extending under the subhymenium, comprising brown, thin-walled, 1.5-3 µm diam. hyphae. Wall hyphae near top of ascocarp margin pale brown to hyaline, amyloid. Periphyses 30-40 x 2-3.5 µm, mostly unbranching. Subhymenium amyloid. Paraphyses 1.5-2 µm diam., not differentiated at tips, amyloid. Asci 230-330 x 8-12 µm, cap 6.5-8 µm thick with a broad central pore, 8-spored. Spores almost as long as asci, coiling tightly on release from asci, 3-5 µm wide, cells 2-3.5 µm long.
Anamorph in vivo: Has not been found.
Characteristics in culture: Ascospores germinating on agar plates in 4 days, forming colonies on OA 3-4 cm diam. after 8 weeks. Aerial mycelium dense, cottony, white with pink tinge. Pycnidia forming on agar surface near centre of colony, globose, 180-300 µm diam., dark walled, opening by an irregular split in wall. Pycnidial wall 15-25 µm thick, comprising dark-walled pseudoparenchymatous or hyphal cells, 2-3.5 µm diam. Conidiogenous cells arising from inner wall layers, cylindric, 7-12 x 1.5-2.2 µm, hyaline, phialidic, thickened collarette, solitary or rarely on short, unbranching conidiophores with apical and lateral apertures. Conidia cylindric with rounded ends, 6.2-10(-12) x 1.8-2(-2.2) µm, hyaline, nonseptate.

Habitat: Found on dead leaves of Astelia trinervia.

Ascocarpi immersi, profunde cupulati, 0.3-0.6 mm diam., margine integro, albo, in sectione transversali 80-120 µm crasso. Stratum crystallinum 50-80 µm crassum. Stratum parietis 40-50 µm crassum, hypharis 1.5-3 µm diam., brunneis. Periphysoidea 30-40 x 2-3.5 µm, non ramosa. Paraphyses filiformes, simplices, in iodo caerulescentes. Asci 230-330 x 8-12 µm, apice 6.5-8 µm crassi, 8-spori. Sporae 3-5 µm diam., cellulis 2-3.5 µm longis.
Holotypus: PDD 42782 ex Astelia trinervia Kirk.

Notes: S. trinervia and S. asteliae are both dark-walled Stictis species found on Astelia leaves. They differ in several respects. S. asteliae has a stromatic layer at the outside of the margin, has nonamyloid paraphyses, has longer and narrower asci, and has larger, semi-erumpent ascocarps with a thick, cushion-shaped margin. S. trinervia is non-stromatic, has amyloid paraphyses, shorter and wider asci, and a non-erumpent ascocarp with a crystalline margin becoming eroded, with crystals being scattered on the surrounding host tissue. The anamorph conidia of S. asteliae are slightly narrower than those of S. trinervia.
Etymology: trinervia; refers to host plant.

Holotype: New Zealand: NORTHLAND: Waipoua State Forest, Yakas Track, on Astelia trinervia, P. R. Johnston, G. J. Samuels, 30 May 1982 (PDD 42782).
