Nectria hauturu Dingley 1951

Collections Examined

Carmichaelia sp.

Auckland, Little Barrier Isl., December 1947, J.M.D. type collection.

Description

Perithecia scattered or aggregated into groups of 2-10 seated on a poorly developed erumpent stroma, globose 0-3-0-5mm. coral or salmon pink, collapsing when dry, ostiole umbilicate ; perithecial wall pseudoparenchymatous 120, thick, outer cells 10-20, diameter, walls lightly thickened and pigmented, subhymenial cells 3-4,ri. diameter, walls thickened and pigmented. Asci elavate or cylindrical 50-90 x 8-10A, 4-8 spored, biseriate; pseudoparaphyses filamentous, branched. Spores one-septate, sometimes unequally divided by septa, fusiform, elliptical or oval, occasionally allantoid, rarely spherical, 9-26 x 4-8µm smooth, hyaline.

Distribution

New Zealand.

Habitat

Carmichaelia sp.

Latin

Perithecia libere sparsa vel gregaria, in stromate parvo et erumpenti, globosa 0 - 3-0 - 5mm. diameter, corallina, corruentia ; ostiolo umbilicato ; pariete perithecii pseudoparenchymato 120, crasso ; cellulis densatis et leviter tinctis. Asci cylindrici vel clavati 50-90 x 8-10,u; 4-8 sporis biseriatis; pseudoparaphysibus. Sporae uniseptatae, fusiformes, ellipticae vel ovatae, 9-26 x 4-8,t, leves, hyalinae.

Notes

Similar to N. cinnabarina differing in that Perithecia are lighter coloured and spores irregular in shape and size. Perithecia collapse when dry. They are aggregated into clusters of 3 to 10 on a small erumpent stroma.

Bionectria ralfsii (Berk. & Broome) Schroers & Samuels 2001

Description

Type: Corticolous Fungi; Description: Ascomata stromatic, perithecial, scattered or aggregated in groups of 2–10, flattened globose, orange-yellow to salmon pink, finely warted, 0.3–0.5 mm in diameter, ostiole papillate, superficial, on a poorly-developed erumpent stroma; on bark on stems. Asci clavate, 50–95 × 8–15 μm. Ascospores elongate elliptical, 1-septate, 15–25 × 4–8 μm, smooth, hyaline. Conidia lemon-shaped, 0-septate, 10–18 × 7–9 μm, smooth, hyaline at first but becoming thick walled and greenish.

Distribution

Distribution: Auckland, Northland, Coromandel, Wanganui, Nelson.; 1st Record: Dingley (1951: as Nectria hauturu).

Nectria ralfsii Berk. & Broome 1854

Collections Examined

On dead branches of Macropiper excelsa Auckland Prov., Whangapoua Saddle, Coromandel Peninsula, 5,1X.1963, J.M.D., DAOM 109379.

Description

Conidia limoniform, 12.5-17(-18.5) X 8-9µm.

Notes

Dingley (1956) indicated that her Nectria hauturu described from Little Barrier L, should be regarded as a synonym of N. ralfsii; she remarked that the conidial state is present on the New Zealand collections which she had seen. Ellis (1971) included the conidial state as Myrothecium but Tulloch (1972) excluded it.
