OTHER SPECIMEN EXAMINED: NORTH ISLAND: GISBORNE: Urewera National Park, Lake Waikaremoana, Ngamoko Track, on wood of ?Weinmannia racemosa, 21 May 1981, G. J. Samuels, P. R. Johnston, E. Horak, A. P. Hawthorne, & R. H. Petersen, PDD 41978.

Stromata (750)867 ± 69(1000) µm high, (750)920 ± 105(1125) µm wide (n = 10), erumpent through the wood, covered with white or brown remnants of host epidermis, subglobose, conical to cupulate, dark brown to black, with rugose to slightly cracked surface, solitary in small groups. Ostioles coarsely papillate. Ectostroma 75-100 µm thick, black. Entostroma below perithecia white to cream. Perithecia detached and collapsed in mature material. Ascus apical rings 5.7-6.7 µm high, upper width 6.7-8.6 µm, lower width 4.8-6.7 µm (n = 10), almost rectangular, without bulge at upper margin, upper end blurred, J+, pale blue. Ascospores (29.7)32.7 ± 1.6(37.4) µm long, (14.4)16.7 ± 1(18.2) µm wide (n = 60), broadly ellipsoidal, dark brown, with spiral germ slit over one and a quarter turn, with a basal, up to 3 3 µm large, semiglobose, cellular appendage.
Cultures on CMD after 36 days at 15-18°C under diffused daylight 0.7 cm diam., scant aerial mycelium, dense, opaque, salmon-coloured with scattered, salmon-coloured sporodochial aggregates, sterile. On PDA under same conditions 1 cm diam., salmon-coloured, felty, dense, opaque, sterile.

HOSTS: Beilschmiedia tawa, ?Weinmannia racemosa.
MATRIX: Decorticated, heavily decomposed wood.

Stromata e ligno erumpentia, albis vel brunneis hospitis epidermidis partibus tecta, (750)867 ± 69(1000) µm alta, (750)920 ± 105(1125) µm lata, subglobosa, conica ad cupulata, brunnea ad nigra, superficie rugosa ad rimulosa, singularia, gregaria. Ostiola grosse papillata. Ectostroma 75-100 µm crassum, nigrum. Annulus apicalis asci 5.7-6.7 µm altus, parte superiore 6.7-8.6 µm et inferiori 4.8- 6.7 µm latus, paene rectangularis, margine superiore non protuberanti, parte finali superiore indistincta, iodo pallide coerulescenti. Ascosporae (29.7)32.7 ± 1.6(37.4) µm longae, (14.4)16.7 ± 1(18.2) µm latae, late ellipsoideae, atrobrunneae, fissura germinativa spiraliter sporam una circumferentiae et quarta parte recurrenti, appendice semiglobosa, ad 3 x 3 µm dimensione, cellulari praeditae.

ETYMOLOGY: After the province Gisborne, where both specimens were collected.
NOTES: Helicogermslita gisbornia is characterised by its large, wide, dark brown ascospores with a spiral germ slit encircling them more than one time and with a cellular appendage.
