Descriptions
Perithecia caespitose on a small pulvinate pseudoparenchymatous stroma, up to 2 mm diameter. Perithecia globose, tuberculate, 250-350 µ in diameter, salmon or ochraceous, ostiole not papillate; perithecial wall pseudoparenchymatous, 40 µ thick, tubercles 30-10 µ high, cells hyaline, 10-15 µ pigment granules present within the cells, subhymenial layer 20-25 µ, walls pale salmon and thickened. Asci clavate. 50-80 x 6-12 µ, 8 spored, biseriate or obliquely uniseriate arranged in ascus. Spores one septate, elliptical or oval, 12-20 x 5-6 µ, hyaline, verrucose, sometimes constricted at septa.
Conidial stage: conidiophores more or less compacted to form a pulvinate stroma to 2 mm diam., verticillately branched. Conidia broadly elliptical, but sometimes allantoid, 5-8.5 x 2-3.5 µ, smooth hyaline.
Conidial stage: conidiophores more or less compacted to form a pulvinate stroma to 2 mm diam., verticillately branched. Conidia broadly elliptical, but sometimes allantoid, 5-8.5 x 2-3.5 µ, smooth hyaline.
Perithecia caespitosa in parvo pulvinato pseudoparenchymato stromate ad 2 mm diam. globosa, tuberculata 250-350 µ diam., salmonea vel ochracea, ostiolo non papillato, pariete pseudoparenchymato, 40 µ crasso, tuberculis 30-40 µ cellulis hyalinis 10-15 µ, granulis tinctis in cellulis et inter eas, regione subhymenii 20-25 µ, parietibus cellularum leviter tinctis et densatis. Asci clavati 50-80 µ x 6-12 µ, 8 sporis biseratis vel oblique uniseratis. Sporae uniseptatae, ellipticae vel ovales 12-20 x 5-6 µ, hyalinae verrucosae, interdum in septis constrictae. Status conidialis: conidiophora compacta in stromata pulvinato ad 2 mm diam. verticillate rimosa. Conidia catenulate ex sterigmatis terminalibus 15-20 x 2-3 µ. Conidia late elliptica, allantoidia 5-8.5 x 2-3.5 µ laevia, hyalina.
The type collection was first included under N. quisquilaris Cke. ; but further collections have shown the species to differ in its tuberculate perithecia and verrucose spores, 12-20 x 5-6 µ in size.
Type collection: on Edwardsia microphylla (Ait.) Salisb., Auckland, Piha, Aug. 1953 (12800).
Type: Corticolous Fungi; Description: Ascomata stromatic, perithecial, aggregated in clusters, globose, salmon pink, 0.2–0.3 mm in diameter ostiole non-papillate, superficial, on a pulvinate stroma up to 2 mm in diameter; on bark on stems. Asci clavate, 50–80 × 6–12 μm. Ascospores elliptical to oval, 1-septate, 12–20 × 5–6 μm, verrucose, hyaline. Conidia elliptical, 0-septate, 8–15 × 2–4 μm, smooth, hyaline.
Distribution: Auckland, Bay of Plenty.; 1st Record: Dingley (1951: as Nectria kowhai).
Significance: None.; Host(s): Corynocarpus laevigatus, Pseudopanax sp., Sophora microphylla.
