ADDITIONAL SPECIMENS EXAMINED: New Zealand: AUCKLAND: Waitakere Ra., Parau Dam, on Dicksonia squarrosa, P. R. Johnston, 21 Sep 1981 (PDD 41876). NORTHLAND: Omahuta State Forest, Picnic area, on Dicksonia squarrosa, P. R. Johnston, G. J. Samuels, R. Peterson, A. Hawthorne, 1 Jun 1982 (PDD 42774).

Ascocarps immersed, 0.3-0.5 x 0.1-0.3 mm, margin comprising 2 or more flaps of host tissue folding back, and lined with crystals, opening elliptical in shape. Margin in cross-section 40 µm wide. Crystals 25-30 µm wide, extending to bottom of margin. Wall 10-20 µm wide, extending from host surface and under subhymenium, comprising hyaline, gelatinised, 1-2 µm diam, hyphae. Periphyses 10-20 x 1-2 µm, unbranching, sparse. Paraphyses 1 µm diam., propoloid, nonamyloid. Asci 57-90 x 6-8 µm, cap 3-4.5 µm thick, 8-spored. Spores 40-80 x 2-2.5 µm, 15-20 septate, slightly tapering to one end.
Anamorph in vivo: Has not been found.
Characteristics in culture: Ascospores germinating on agar plates within 2-4 days, forming colonies 1 cm diam. after 6 weeks. Colonies pustulate, yellow or orange in colour, undulate surface, lacking aerial mycelium, sterile.

habitat: Dead fronds of tree ferns.

Ascocarpi immersi, 0.3-0.5 x 0.1-0.3 mm, margine lacerato, albo, in sectione transversali 40 µm crasso. Stratum crystallinum 25-30 µm crassum. Stratum parietis 10-20 µm crassum, hypharis 1-2 µm diam., achromis. Periphysoidea 10-20 x 1-2 µm, non ramosa. Paraphyses filiformes, ramosae, in iodo non caerulescentes. Asci 57-90 x 6-8 µm, apice 3-4.5 µm crassi, 8-spori. Sporae 40-80 x 2-2.5 µm, 15-20 septatae. Holotypus: PDD 41877 ex Cyathea dealbata (Forst. f.) Schwartz.

Notes: S. laciniata is similar to S. javanica Sherwood (Mycotaxon 5: 197). The New Zealand species differs in having longer, narrower, more closely septate ascospores, and in being found on a different sort of host. It differs from S. dumontii in having 8-spored asci and narrower ascospores.
Etymology: laciniata = flap; refers to appearance of ascocarp, with surrounding host tissue folding back in small flaps.

Holotype: New Zealand: AUCKLAND: Waitakere Ra., Chateau-Mosquito Track, on Cyathea dealbata, P. R. Johnston, 19 Jan 1982 (PDD 41877).
