Pseudowintera colorada (Raoul) Dandy. Otago, Lower Hollyford, January 1950, J.M.D. (2 col. one being type).
Perithecia gregarious in erumpent clusters of 10 or more, stroma absent; globose 0.2-0.4mm. diameter, scarlet, fading to ferruginous, wrinkled occasionally with irregular tubercles, ostiole distinct, papillate and surrounded by a disc of smooth tissue; perithecial wall pseudoparenchymatons 40-501, thick, cells 5-15 x 5-101, rectangular or cuboid, pigmented and thickened. Asci elliptical or clavate, 74-110 x 10-14p,, 8 spored, spores biseriate, occasionally uniseriate at base, pseudoparaphyses filamentous, branched. Spores one-septate, elliptical, filiform 15-22 x 4-5-6'x, smooth, hyaline. Conidial stage; conidiophores stout, compacted to form a pale salmon stroma,. Conidia globose or elliptical 3-7 x 3-4 µm Tubercalaria sp.

Pseudowintera colorada. (Raoul) Dandy.

Perithecia rearia in corona erumpenti, globosa 0-2-0-4min. diam., miniata ad colorem ferrugirienrn pallescentia; ostiolo papillato; pariete perithecii pseudoparenchymato 40-50p, crasso; cellulis 5-151, diam., parietibus densatis et tinctis. Asci clavati vel elliptici; 8 spores biseriatis. Sporae uniseptatae, ellipticae, filiformes,. 15-22 x 4-5-61, leves, hyalinae. Status conidialis. Conidia globosa vel elliptica, 3-7 x 3-4µm.
