Anthostomella okatina Whitton, K.D. Hyde & McKenzie 2000

Material examined: NEW ZEALAND, North Island, Rotorua region, in forest surrounding Lake Okatina, on decaying leaves of Freycinetia banksii, 25 May 1996, S.R. Whitton (HKU(M) 5013, holotype).
Ascomata immersed, visible as small, blackened, raised, circular papilla, 75-105 µm diam., brown, coriaceous (Fig. a); in vertical section 114-136 µm diam., 130-144 µm high, globose to broadly obclavate, basal part often almost flat (Fig. b). Peridium 14-22 µm wide, comprising several layers of flattened to elongated cells, walls hyaline and thin-walled at the inside, and pale-brown and thick-walled towards the outside (Fig. b). Paraphyses 1-2.5 µm wide, filamentous, hyaline, flexuose, numerous, septate, tapering at the apex. Asci 70 - 90 x 7 - 9.5 µm ( = 82.5 x 7.8 µm, n = 20), 8-spored, cylindrical, unitunicate, short-pedicellate, lacking any visible apical apparatus (Figs. c-g). Ascospores 12-15 x 4.5-6 µm (mean = 13.6 x 5.2 µm, n = 25), overlapping uniseriate or partly biseriate, inequilaterally ellipsoidal, palebrown to brown, unicellular, smooth-walled, lacking a mucilaginous sheath, germ slit spiral (Figs. h-m).
Known distribution: New Zealand.
Known host: Freycinetia (Pandanaceae).
Ascomata 114-136 µm diam., 130-144 µm alta, immersa, globosa vel late obclavata, ostiolate, clypeata. Asci 70-90 x 7-9.5 µm, deficio apicali apparatu. Ascosporae 12-15 x 4.5-6 µm, inaequilaterales ellipsoideae, vel fusoida, fissura germinativa helicoideo praeditae.

Etymology: okatina refers to the type locality, in forest surrounding Lake Okatina, Rotorua, New Zealand.

Ascospores of A. okatina are similar in shape to those of A. spiralis K.D. Hyde and B.S. Lu, but differ as ascospores of A. okatina lack a mucilaginous sheath and asci lack any visible apical apparatus.
