Additional material.—New Zealand,: South Island: Nelson, Lake Rotoiti, under Nothofagus fusca, N. menziesii and N. solandri var. cliffortioides, 30.IV.1968, leg. Horak (ZT 68/324).—Southland: Te Anau Downs, Denton Creek, under Nothofagus solandri var. cliffortioides, 1.IV.1969, leg. Horak (ZT 69/214).

Two well developed collections of H. coacta McNabb have been made in New Zealand. All macro- and microcharacters observed indicate that this fungus is conspecific with H. aurantiaca (Fr.) a wide spread species both in the northern hemisphere (Bigelow 1975: 63) and in temperate South America (Singer 1964: 98). According to Corner (1966: 132) H. aurantiaca (Fr.) is already reported from Australia and for that reason the New Zealand records extend the area of distribution in Australasia.

New Zealand: Maungaroa, leg. Berggren, 138 (holotype, K).  South Island: Nelson, Lake Rotoiti, Mt. Robert under Nothofagus fusca, leg. Horak (ZT 68/342).

Pileus -65 mm, centre depressed, umbilicate or funnel-shaped from the beginning, margin strongly inrolled; dark brown to soot brown; velutinous to felty all over, surface cracking in aged specimens dry, margin not striate, veil remnants absent. Lamellae moderately crowded, decurrent, 4 dichotomously forked; whitish to cream becoming pale argillaceous with age; edge rounded, concolorous. Stipe –50 x -6 mm, cylindric or tapering towards base, occasionally fusoid, central; pale brown, villous base white; glabrous, dry, solid, cespitose or single in groups. Context pale brown. Odour and taste not distinctive. Chemical reactions unknown. Spore print white. Spores 5.5 - 7.5(-8) x 3 - 4.5 µm, hyaline, membrane thinwalled, smooth, strongly dextrinoid. Basidia 30 – 45 x 5 - 7 µm, 4-spored. Cystidia absent. Cuticle a palisade of clavate to fusoid cells 35 – 80 x 5—15 µ), membrane thin-walled, not gelatinized, with dark brown vacuolar and plasmatic pigment. Clamp connections present.

On soil among litter under Nothofagus spp. — New Zealand.

McNabb’s description of this characteristic species of Hygrophoropsis was drawn from the rather short original diagnosis supplemented by microscopic data observed on the poorly preserved type material (compare also Corner 1966: 75). Under these circumstances my description of H. umbriceps (taken from fresh and well preserved fruitingbodies) is presented:

BAKER (ZT 68/219).  -Craigieburn, near Base Camp, 1000 m, under Nothofagus solandri var. cliffortioides, 19.IV.1968, leg.

The elliptic spores distinctly separate P. nothofagi from the two other native New Zealand species of Paxillus. Size and shape of the spores remind of those in P. involutus (Fr.) which, however, is readily distinguished by the presence of large cystidia.

NEW ZEALAND: South Island: Nelson, Lake Rotoiti, Mt. Robert, under Nothofagi solandri var. cliffortioides, 3. V. 1968, leg. HORAK (ZT 68/356).

This species is closely related to P. statuum (SPEGAZZINI) HORAK, a very common fungus in the Nothofagus forests of Chile and Argentina (HORAK 1980).

New Zealand: Fjordland: Lake Te Anau, Mt. Luxmore, 9.IV.1969, leg. Horak (ZT 69/330).

Pileus —20 mm, convex at first soon umbonate-expanded, papillate centre sometimes depressed, margin inrolled in young specimens later becoming incurved and conspicuously notched, margin not striate; whitish to pale argillaceous; dry, smooth to appressedly fibrillose veil remnants absent. Lamellae 1-16 (-3) moderately crowded broadly adnate to subdecurrent, up to 3 mm wide; argillaceous to cinnamon; edge concolorous, even. Stipe –30 x -2.5 mm, cylindric to subclavate, central; at apex concolorous with pileus, reddish brown towards base, basal tomentum absent; glabrous or minutely fibrillose, dry, fistulose, shingle in groups. Context whitish. Odour and taste not distinctive. Chemical reactions on pileus: KOH negative. Spore print pale brown. Spores 4 - 5.5x3.5 (-4) µm, subglobose to ovoid, pale brown, densely covered with hemispheric warts or short cylindric projections, membrane thin-walled, inamyloid.

On soil among moss under Nothofagus solandri var. cliffortioides and N. menziesii.—New Zealand.

This species was well described by Métrod (1946: 74) and Huijsman (1960: 335), and the New Zealand collection agrees in all taxonomically important details with European specimens. The following description is taken from fresh carpophores collected in New Zealand:
