PARATYPES - NEW ZEALAND, North Island, Auckland District: Titirangi, Nov. 1931, col. M. Hodgkins, PDD 29714; Titirangi, Atkinson Park, 3 July 1966, col. R. F. R. McNabb, PDD 29710. South Island, Westland District, Longford, Buller Gorge, March 1931, col. M. Bowland, PDD 29711.
Ascocarps hypogeous to subhypogeous, as dried up to 3.5 cm in diam, subglobose to lobed. Peridium verrucose with subangular warts 0.2-0.4 x 0.2-1.0mm, small pubescent patches scattered among the warts, the thin epicutis brown and the thick subcutisyellowish white. Gleba yellowish white, with labyrinthine chambers 0.2-1 mm broad and completely stuffed with asci and spores from adpressed hymenia.Spores ellipsoid, smooth in youth, 19-26 x 15-18 µm excluding ornamentation, 32-38 x 20-28 µm including ornamentation at maturity of a vinaceous brown, amorphous epispore 1-3 µm thick with rounded knobs and ridges 4-12 x 2-5 µm, the knobs on spore ends frequently larger than those on the sides. Spore walls strongly cyanophilic, at maturity the epispore cyanophilic but strongly so only on the outer sides of the knobs and ridges. Asci cylindric, mostly 230-280 x 25-30 µm, mostly with 8 uniseriate spores, hyaline, nonamyloid, thin-walled, tapered to a broadly croziered base, indehiscent, persistent, borne among paraphyses in the hymenia. Paraphyses ± 2 µm in diam, hyaline, thin-walled, frequently septate, straight, round-tipped, equaling or shorter than the asci. Peridial tissue with an epicutis 50-150 µm thick, of ± isodiametric cells 10-25(-30) µm in diam, with yellowish brown walls 2-3 µm thick, grading to the subcutis of interwoven, hyaline hyphae 4-6 µ m in diam. Glebal tissue similar to that of subcutis. Subhymenium, of interwoven, hyaline, thin-walled hyphae 4-8 µm in diam with occasional cells inflated to 10-12 µm.
Known only from North and South Islands, New Zealand.
Ascocarpia exsiccata usque ad 3.5 cm in diam, subglobosa vel lobata. Peridium verrucosum, fragmentulis pubescentibus, brunneum. Gleba loculis labyrinthinis, hymeniis limitatis, sporis et ascis farctis. Asci cylindrici, pro parte maxima octospori, inamyloidei. Sporae ellipsoideae, 19-26 x 15-18 µm sine ornamentis; episporis 1-3 µm incrassatis, amorphis, brunneo-vinosis, nodosis et porcatis. Paraphyses ± 2µm in diam, aequales vel inferiores quam asci Holotypus: PDD29712.
Etymology: In honor of New Zealand mycologist Joan M. Dingley, who recognized the novelty of this species; Latin, verrucosus (warty).
