Additional specimen examined: New Zealand: GISBORNE: Lake Waikaremoana, Black Beech Track, on Coriaria arborea Lindsay, P. R. Johnston, 2 Jun 1981 (PDD 41841).

Ascocarps deeply immersed, urceolate, 0.7-1.5 mm diam., opening widely, becoming semi-erumpent, crystalline margin entire to lacerate, white. Hymenium yellowish, splitting away from margin when dry. Margin in cross-section 110-120 µm wide. Crystals forming a 50-100 µm wide cap in top half of margin. Wall layer 5-20 µm wide, not extending under subhymenium, comprising hyaline, 1.5-3 µm diam. hyphae. Periphyses 25-60 x 1-1.5 µm, branching, forming an extensive, well developed layer. Paraphyses 0.8-1 µm diam., circinate with some small side branches, amyloid. Asci 180-250 x 7-9 µm, cap 3.5-4.5 µm thick, 8-spored. Spores filiform, not tapering, but coiling tightly on release from asci, slightly shorter than asci, 3-3.5 µm wide, cells 3-4.5 µm long, sometimes irregularly disarticulating at septa.
Anamorph in vivo: Has not been found.
Characteristics in culture: Spores germinating on agar plates after 4 days, slowly growing, forming colonies on OA 5 mm diam. after 5-8 weeks. Colonies pustulate with white, cottony mycelium, sterile.

Habitat: Found on dead wood.

Ascocarpi immersi, profunde cupulati, 0.7- 1.5 mm diam., margine integro, albo, in sectione transversali 110-120 µm crasso. Stratum crystallinum 50-100 µm crassum. Stratum parietis 5-20 µm crassum, hypharis 1.5-3 µm diam., achromis. Periphysoidea 25-60 x 1-1.5 µm, ramosa. Paraphyses filiformes, circinatae, in iodo caerulescentes. Asci 180-250 x 7-9 µm, apice 3.5-4.5 µm crassi, 8-spori. Sporae 3-3.5 µm diam., cellulis 3-4.5 µm longis.
Holotypus: PDD 42783 ex decorticated wood.

Notes: S. tortilis is similar in external appearance to S. prominens, which is also found on dead wood. S. tortilis has wider and shorter asci and ascospores, and has ascospores coiling on release from asci. Growth in culture also differs, with S. tortilis growing much more slowly than S. prominens.
Etymology: tortilis = twisted; refers to appearance of released ascospores.

Holotype: New Zealand: NELSON: Motueka, vic. Pokororo, Graham River Valley, on wood, G. J. Samuels, P. R. Johnston, R. Peterson, 14 May 1982 (PDD 42783).
