Nectria ruapehu Dingley 1951
Coprosma pseudocuneata Oliver. Wellington, Mangatoratoru Stream, Mt. Ruapehu, March 1948, J.M.D. type collection; Whakapapa-iti Stream; October 1949, J.M.D.
Perithecia gregarious or caespitose on or immersed in a poorly developed pseudoparenchymatous stroma, globose 0-2-0-5mm. diameter, coral coloured darker when mature, translucent, ostiole small, indistinct, perithecial wall pseudoparenchymatoas 55-60pt thick, cells 8-1O µm, diameter, outer cells thick walled but hyaline, inner cells pigmented. Asci cylindrical 45-65 x 6p,, 8 spored, obliquely uniseriate ; pseudoparaphyses diffluent. Spores one-septate, broadly elliptical constricted at septa 8-11 x 5-6p,, sometimes non-septate, globose, 6-8p, diameter, verrucose, yellow, thick walled.

Coprosma pseudocuneata Oliver.
Perithecia gregaria vel caespitosa in strornate parvo et pseudoparenchymato; globosa, 0-2-0-5 µm. diam., corallina, translucida; ostiolo obscuro ; pariete perithecii pseudoparenchymato 55-60p, crasso ; cellalis exterioribus hyalinis; cellulis interioribus leviter tinctis. Asci cylindrici 45-65 x 6t k; parientibus tenuibus; 8 sporis, oblique uniseriatis; pseudoparaphysibus absentibus. Sporae uni-septatae, late ellipticae, S-11 x 5-6p., verrncosae, pallide luteae.
Perithecia appear in small clusters of 3-10 often on an old leaf scar at the base of a lateral branch. Spores are broader than those of N. hauturu, and perithecia are immersed in the stroma similar to a Hypocrea. The perithecial wall consists of thick walled, almost hyaline cells.
LOCALITY: Mangatorutoru Stream, Mt. Ruapehu.
