Material examined. NEW ZEALAND, North Island, Manawatu Region, Manawatu Gorge Scenic Reserve, on dead leaves of Freycinetia banksii, 30 Apr. 1997, S.R. Whitton (HKU(M) 5008, holotype).
Ascomata immersed, visible as a small, blackened, circular zone, with a central, blackened, raised papilla, dark-brown, coriaceous, clustered or mostly solitary (Fig. a); in vertical section 150-254 µm diam., 172-260 µm high, globose (Fig. b). Clypeus 125-225 µm diam., comprising a small amount of dark-brown, intracellular hyphae and host cells directly surrounding the erumpent papilla (Fig. b). Peridium 20-36 µm wide, comprising 6-8 layers of compressed cells, walls hyaline at the inside, and blackish-brown and thick-walled towards the outside (Fig. b). Paraphyses filamentous, flexuose, hyaline, numerous, septate and embedded in a gelatinous matrix (Fig. c). Asci 92-114 x 12-16 µm ( = 98.6 ´ 14.7 µm, n = 15), 8-spored, cylindrical, unitunicate, short-pedicellate, apically rounded, lacking any visible apical apparatus (Figs. c, d). Ascospores 11.5-18 x 9-12 ´ 7.5-9 µm (14.3 x 10.2 x 7.8 µm, n = 25), uniseriate to overlapping uniseriate, broadly ellipsoidal, with both ends rounded, narrower in side view, pale-brown at immature, dark-brown at mature, unicellular, lacking a mucilaginous sheath, germ slit straight, 6-8.2 µm long (Figs. e-i).
Known distribution: New Zealand.
Known host: Freycinetia (Pandanaceae).
Ascomata 150-254 µm diam., 172-260 µm alta, immersa, globosa, ostiolata, clypeata. Asci 92-114 x 12-16 µm, deficio apicali apparatu. Ascosporae 11.5-18 x 9-12 x 7.5-9 µm, late ellipsoideae, fissura germinativa directa, abbreviata.
Etymology: manawatua refers to the type locality, Manawatu, New Zealand.
Ascospores of Anthostomella manawatua are similar in shape to those of A. dilatata (Berk. and Broome) Petch, but ascospores of A. manawatua are smaller and narrower (11.5-18 x 9-12 x 7.5-9 µm, vs 15.5-22.5 x 12.5-16.5 x 8-9 µm). In addition, the germ slit of A. manawatua is shorter than the length of the ascospores, while those of A. dilatata are full-length.
