Amanita australis G. Stev. 1962

Basidiocarps very small to medium, solitary or rarely gregarious. Pileus 20-90 mm wide, convex to piano-convex, then piano-depressed, margin occasionally splitting and rolling back to give a ragged appearance, disc dark buff, honey or isabelline, paling to buff at the margin, viscid when young or wet, drying with age, volva remnants forming conical to pyramidal warts aggregated on disc, becoming sparse and low towards the margin, at first white then greyish sepia or isabelline with white to buff tips. Lamellae crowded, free, 6-10 mm wide, white, margin entire; lamellulae truncate. Stipe 37-90 mm high, 6-26 mm diameter, narrowest at centre, hollow, from sub-bulbous to abruptly bulbous base, 14-38 mm diameter, surface above annulus white, floccose, below annulus white with white, buff or sordid transverse, striate bands, base with or without a rim of pulverulent, sordid buff to greyish sepia volva remnants. Annulus membranous, striate, white to buff, pendulous then adhering to stipe. Context of pileus white, occasionally pale isabelline under disc, rarely a grey line above lamellae, stipe white.

Spore print white. Basidiospores (367/31), (8-)9-12(-13-14.5) x (7-)8-10.5 µm, Qm 1.10, Q 1.00-1.33(-1.60), globose to ellipsoid, thin-walled, hyaline, amyloid. Basidia 43.5-76.5 x 10.5-17 µm, mostly 4-spored, clamped. Lamella margin cells numerous, 16-39.5 x 10.5-27.5 µm, globose, elliptic or clavate, hyaline. Pileipellis consisting of 220-270 µm wide, gelatinised suprapellis and non-gelatinised subpellis. Volva remnants on pileus consisting of abundant globose, clavate, napiform cells, 10-86 x 9-85 µm, pale umber to umber, in chains perpendicular to the pileus surface, becoming smaller and paler at tip of wart, subtended by moderately abundant hyphae, 4-10 µm wide, clamp connections abundant.

Holotype: New Zealand, Wellington region. Day's Bay, 41°17'S, 174°54'E (map 52), 7.VI.l952, under Nothofagus, G. Stevenson 860 (K).
Basidiospores (15/1), 9.5-10.5 x 8.5-9.5 µm, Qm 1.09, Q 1.05-1.1 l(-l.17), subglobose to broadly ellipsoid, hyaline, amyloid. Basidia 47-53 x 11.5-16.5 µm, 4-spored, with clamp connections. Lamella margin cells present but failed to reinflate. Acrophysalides present.
This specimen was badly decomposed when it was dried and little microscopic detail has survived. The size, shape and amyloid reaction of the spores, the dimensions of the basidia, the presence of clamp connections and lamella margin cells indicate that this is Amanita australis Stevenson and easily fits into the concept of this taxon (Ridley 1992). Macroscopically the specimen lacks the typical pronounced basal bulb to the stipe and volva remnants on the pileus; however, it is not an unknown condition in this taxon. All the evidence indicates that A. macrospora Stev. is a synonym of A. australis Stev.

Amanita australis G. Stev. 1962

Pileus 6-9 cm. diam., buff coloured, darker at centre, moist, smooth, thickly dotted with brownish-buff warts. Gills free, creamy-white, fairly crowded. Stipe 1-2 x 4-9 cm. white, satiny, or with some cottony fibrils, hollow; ring conspicuous, membranous; volva fused to a strongly bulbous base. Spores amyloid, subglobose, 8 x 10-9 x 12um. Faint acid smell.
rooting in Nothofagus litter at Lake Rotoiti, Nelson, 5.3.1955, Stevenson.
Pileus 6-9 cm. diam., luteofuscus centro tenebrosior, humidus, laevis, verrucis brunneis vel luteofuscis dense maculatus. Lamellae liberae, luteo- albae, mediocriter confertae. Stipes 1-2 x 4-9 cm., albus, nitidus vel fibrillis laneis, cavus; annulus conspicuus, membranaceus; volva basi valde bul- bosae juncta. Sporae amyloideae, subglobosae, 8 x 10- 9 x 12um. Odor exigue acidus
This species is near to A. citrina but differs in having larger spores, and also in having more concrete numerous warts on the cap, rather than a few soft pieces of residual membrane
Stevenson 970
Pileus 6-9 cm. diam., pale-fawn, moist, smooth, pellicle peeling; flesh white. Gills free, white, becoming pale yellow in older specimens, moderately crowded, long and short intercalated. Stipe 1-2 x 10-14 cm., pale fawn, floccose above ring, fibrillose below; ring of residual fibrils; veil of continuous cobwebby strands from cap edge to all lower parts of stipe. Spores arnyloid, globose, 7-8 x 8-~op. Pellicle of gelatinized hyphae. Strong sour smell.
under Nothofagus at Day's Bay, Wellington, 7.6.1952, Stevenson.
Pileus 6-9 cm. diam., pallide-hinnuleus, humidus, laevis; pellicula desquamans; car0 alba. Lamellae liberae, albae demum pallido-luteae, mediocriter confertae, longae et breves intercalatae. Stipes 1-2 x 10-14 cms., pallido-hinnuleus, super annulum floccosus, infra fibrillosus; annulus ex fibrillis residuis: velum e filis continuis tenuissimis a margine pilei ad omnes partes inferiores stipitis decurrentibus. Sporae amyloideae, globosae, 7-8 x 8-~op. Pellicula ex hyphis glutinosis. Odor valde acerbus.
The spores, amyloid in reaction and larger in size, distinguish this species from any of the previously described Limacellae
Stevenson 860.
