Material examined: NEW ZEALAND, North Island, Kapiti Coast, north of Paraparaumu, Kikau Researve, on decaying leaves of Freycinetia banksii, 1 May 1997, S.R. Whitton (HKU(M) 5007, holotype); ibid., 2 Jun. 1996, S.R. Whitton (HKU(M) 5019); North Island, Wellington Region, in forest alongside Akatarawa Hill Road, on decaying leaves of Freycinetia banksii, 1 May 1997, S.R. Whitton (HKU(M) 14068).

Ascomata immersed, no raised papilla but still clearly visible on the host surface, dark-brown, coriaceous, mostly clustered or solitary (Fig. f); in vertical section 260-280 µm diam., 180-200 µm high, ellipsoidal, with a central ostiole (Fig. g). Clypeus very reduced to almost non-existent, comprising a small amount of hyphal growth around the neck of the ostiole (Fig. g). Peridium 18-28 µm wide, comprising 5-7 layers of elongated cells, walls light-brown and thin-walled at the inside, and dark-brown and thickwalled towards the outside. Paraphyses 1.5-3 µm wide, filamentous, flexuos, numerous and septate. Asci 92-138 x 15-20 µm (mean = 115.4 x 18.3 µm, n = 10), 8-spored, cylindrical, unitunicate, short-pedicellate, apically rounded, with a faint, J+, wedge-shaped, subapical ring, 4-6 µm (= 4.8 µm, n = 10) diam., 36 µm (= 5.2 µm, n = 10) high (Figs. h-l). Ascospores 17-23 x 10-12.5 (= 18.7 x 11.5 µm, n = 25), uniseriate, broadly inequilaterally ellipsoid fusoid, both ends broadly rounded, brown to dark-brown, unicellular, smooth and thick-walled, germ slit straight, extending over the full-length (Figs. a-e).

Known distribution: New Zealand.

Known host: Freycinetia (Pandanaceae).

Ascomata 260-280 µm diam., 180-200 µm alta, immersa, ostiolata, clypeata. Asci 92-138 x 15-20 µm, apparatus apicali iodo coerulescente. Ascosporae 17-23 x 10-12.5 µm, late fusoidea vellate inequilaterales ellipsoideae.

Etymology: kapitiae refers to the type locality, the Kapiti Coast, New Zealand. Ascospores of Anthostomella kapitiae are similar in shape to those of A. dilatata (Berk. and Broome) Petch, but asci in A. dilatata lack any visible apical apparatus. Anthostomella kapitiae differs from A. tenacis (Cooke) Sacc. as ascospores of A. tenacis are much smaller (7.5-12.5 x 5-6.5 x 2.5-4 µm).
