Limacella macrospora G. Stev. 1962
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.
Limacella macrospora G. Stev. 1962
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.
