Additional specimen examined: New Zealand: AUCKLAND: Waitakere Ranges, Centennial Track, on Astelia solandri, 12 Oct. 1982, P.R. Johnston R102 (PDD 43267).

Infected areas on dead leaves, paler than surrounding leaf tissue, not associated with zone lines, containing scattered ascomata, conidiomata not seen. Ascomata 0.5-0.8 x 0.3-0.4 mm, elliptical to oblong in outline, ends rounded, wall black with poorly-defined paler zone alone, future line of opening, single, longitudinal opening slit with black flattened zone along either side. Ascomatal insertion subepidermal. Ascomatal structure typical of Terriera (see p. 37). Paraphyses 1-2 µm diam., ± undifferentiated at apex, extending 15-20 µm beyond asci. Asci 75-105 x 8-10.5 µm, cylindrical, apex broadly-truncate with undifferentiated wall, 8-spored, short, broad basal stalk with spores extending almost to base. Ascospores 45-70 x 2-2.5 µm, tapering slightly to ends and slightly constricted near centre, non- or 1 -septate, gently curved on release, with no gelatinous sheath.

JOHNSTON (1989b, figs 1, 20, as Lophodermium asteliae).

Terriera asteliae is characterized within the genus by its broad asci with a broad-truncate apex. Terriera fuegiana, described on Rostkovia from Tierra del Fuego, has similar-sized asci and ascospores. Although the only material of T fuegiana available is in poor condition, the asci appear to be broadly rounded at the apex, and illustrations by SPEGAZZINI included in the packet clearly show asci of this shape. Structures resembling conidiomata of Rhytismataceae were associated with the ascomata, but conidiogenous cells and conidia were not seen.

Additional specimens examined: New Zealand: AUCKLAND: Marguerite Track, on Gahnia, 15 Oct. 1975, G.J. Samuels s. num. (PDD 47493); Waitakere Ranges, Karamatura Stream, on Gahnia, 3 Sep. 1976, G.J. & C. Samuels. s. num.. (PDD 37127); COROMANDEL: Little Barrier 1, Shag Track, on Uncinia, 15 Jun. 1984, P.R. Johnston LB29 (PDD 46121); Port Charles, between wharf and Big Sandy Bay, on Carex, 29 Dec. 1993, P.R. Johnston s. num. (PDD 62551).

Infected areas on dead leaves, no paler than surrounding leaf tissue, not associated with zone lines, containing scattered ascomata, conidiomata not seen. Ascomata on Uncinia 0.6-1-2 x 0.2-0.3 mm, oblong-elliptical in outline, ends rounded, on Gahnia 1-5 x 0.2-0.4 mm, often sublinear, in unopened ascomata wall black with paler zone along future line of opening, in opened ascomata wall black, oriented at high angle to surrounding host tissue, single, longitudinal opening slit with narrow, black, shelf-like zone along either side. Ascomatal insertion subepidermal. Ascomatal structure typical of Terriera (see p. 37). Paraphyses 1-2 µm diam., undifferentiated to slightly swollen at apex, unbranched, embedded in thick gel, extending as compact epithecium 10-15 µm beyond asci. Asci 110-135 (-160) x 6-7 µm, cylindrical, tapering gradually to rounded apex with slightly thickened wall, 8-spored, narrow basal stalk with spores extending 80-90 µm from ascus apex. Ascospores (55-) 60-75 x 1.5-2 µm, tapering slightly to ends, non- or 1-septate, gently curved or sigmoid on release, with no gelatinous sheath.

New Zealand: Campbell 1, on Uncinia hookeri, s. dat., coll. nec num. (K!, holotype).

Infected areas on dead leaves, slightly paler than surrounding host tissue, associated with partial zone lines, containing ascomata and conidiomata. Ascomata 0.7-1-7 x 0.2-0-3 mm, elliptical to sublinear in outline, unopened ascomata wall black, with pale areas near both ends, and with faint pale zone along future line of opening, single longitudinal opening slit with black shelf-like zone along either side. Ascomatal insertion subepidermal, sometimes also beneath scattered host fibre bundles. Ascomatal structure typical of Terriera, but with darkened lower wall very well developed. Paraphyses 1-1 5 µm diam., undifferentiated at apex, embedded in gel, extending c. 20 µm beyond asci. Asci 70-80 x 5-6.5 µm, subclavate, tapering slightly to truncate apex with slightly thickened wall and small central pore, 8-spored, well-developed basal stalk with spores confined to upper 40-50 µm. Ascospores 30-35 x 1 µm, tapering slightly to ends, gently curved or sigmoid on release, 1-septate, gelatinous sheath lacking. Conidiomata 0.3 mm diam., round in outline, wall pale brown with darker line around outside edge, in vertical section upper and lower walls comprising one to three rows of brown to pale brown cells and lined with one or two rows of thin-walled, hyaline cells on which conidiogenous cells are held. Conidiogenous cells 8-12 x 1.5-2.5 µm, solitary, tapering to apex, proliferation sympodial, often with 2 developing conidia held at apex. Conidia 3-4 x 1 µm, oblong-elliptical with ends rounded, non-septate, hyaline.

Terriera nematoidea is distinguished by its short, broad asci with a truncate apex and short ascospores. Unusually for a species of Terriera, the epithecium is poorly developed.
