Other specimens examined: New Zealand: AUCKLAND: Waitakere Ra., Cascades Track, on Brachyglottis repanda J. R. et G. Forst, P. R. Johnston, G. J. Samuels, 16Jul 1980, (PDD 41050); Waitakere Ranges, Cascades Track, on Geniostoma ligustrifolium, P. R. Johnston, 10 Feb 1981 (PDD 41866); Hunua Ra., on Pittosporum sp., P. R. Johnston, G. J. Samuels, H. D. Thiers, 3 Apr 1981 (PDD 41867).
Ascocarps immersed, urceolate, round to elongate, 0.2-0.4 mm diam., crystalline margin entire or lacerate. Margin in cross-section 60-90 µm wide. Crystals forming a 50-80 µm wide, wedge-shaped layer in top half of margin. Wall layer poorly developed, 5-10 µm wide, extending only half way up the margin, and not under the subhymenium, comprising hyaline, 1.5-2 µm diam. hyphae. Periphyses sparse, 10-15 x 1-2 µm, unbranching. Paraphyses swollen at tips, 2-2.5 µm diam., not branching, nonamyloid. Paraphyses may be faintly amyloid in some collections. Asci 70-95 x 7-11 µm, cap 3.5-5 µm thick, 8-spored. Ascospores 40-56 x 3-4.5(-6) µm, 10-15 septate, sometimes disarticulating into irregular-sized spore pieces.
Anamorph in vivo: Has not been found.
Characteristics in culture: Ascospores from one collection germinating on agar plates within 4 days. Colonies slow growing, pustulate, pale yellow to orange in colour, lacking aerial mycelium, sterile.
Habitat: Dead twigs of woody plants.
Ascocarpi immersi, profunde cupulati, 0.2-0.4 mm diam., margine integro vel lacerato, albo, in sectione transversali 60-90 µm crasso. Stratum crystallinum 50-80 µm crassum. Stratum parietis 5-10 µm crassum, hypharis 1.5-2 µm diam., achromis. Periphysoidea 10-15 x 1-2 µm, non ramosa. Paraphyses filiformes, simplices, apice ad 2-2.5 µm incrassatae, in iodo non caerulescentes. Asci 70-95 x 7-11 µm, apice 3.5-5 µm crassi, 8-spori. Sporae 40-56 x 3-4.5(-6) µm, 10-15 septatae.
Holotypus: PDD 41868 ex lignum.
Notes: S. paucula differs from the other Stictis species with swollen paraphyses in ascospore shape and size. S. dumontii has similar sized spores, but has 4-spored asci, and propoloid paraphyses.
Etymology: paucula = few; refers to the few, scattered ascocarps in all the collections.
Holotype: New Zealand: AUCKLAND: Waitakere Ra., Kitekite Track, on dead wood, P. R. Johnston, G. J. Samuels, M. E. Lanigan, 3 Sep 1980 (PDD 41868).
