intro |
The following description is based on Ridley (1991). |
cap |
The cap of Amanita pareparina is 40 - 115 mm wide, convex to plano-convex, or flattened-conic, pale yellowish-ochraceous, occasionally with slight rosy buff tinge, dry, possibly subviscid when wet, with an appendiculate and decurved margin. The cap tends to split into large, fleshy squamules, conical to broadly conical warts that become smaller, subfelted crumbs towards the margin; these volval remnants are pale yellowish to ochraceous at the tip. The flesh is white to very pale buff and unchanging. |
gills |
Gills are crowded, free, smooth to slightly floccose, very pale buff; the short gills are attenuate. |
stem |
Its stem is 50 - 120 × 10 - 18 mm, solid; flushed rosy buff, floccose, and striate above the ring, pale yellowish, fibrillose, and becoming finely scaled below the ring. The bulbous base is 28 - 42 mm wide. Upwards pointed scales becoming larger towards the stem base. These scales suggest a palisade which gives the species its latinized Maori name. The ring is membranous, striate, tearing unevenly, pale yellowish. The flesh is white to very pale buff and unchanging. |
spores |
The spores measure 8 - 12 × (6.5-) 8 - 10.5 µm and are globose to broadly ellipsoid infrequently ellipsoid and are amyloid. Clamps are absent at bases of the basidia. |
discussion |
Originally described from New Zealand, associated with Southern Beech (Nothofagus). It is known from the southern part of the North Island and the Northern part of the South Island. Ridley reports that he was unable to place A. pareparina within Bas' system. It is curious that the colors yellow and rosy buff appear on this mushroom as well as on A. mumura G. S. Ridl.—R. E.

intro |
The following text may make multiple use of each data field. The field may contain magenta text presenting data from a type study and/or revision of other original material cited in the protolog of the present taxon. Macroscopic descriptions in magenta are a combination of data from the protolog and additional observations made on the exiccata during revision of the cited original material. The same field may also contain black text, which is data from a revision of the present taxon (including non-type material and/or material not cited in the protolog). Paragraphs of black text will be labeled if further subdivision of this text is appropriate. Olive text indicates a specimen that has not been thoroughly examined (for example, for microscopic details) and marks other places in the text where data is missing or uncertain. The following is based entirely on the protolog of the present species. Basidiocarps small to large. | ||||||||
pileus | 40 - 115 mm, pale luteous ochreous, occasionally with slight rosy buff tinge, dry, possibly subviscid when wet, tending to split into large, fleshy squamules, convex to plano-convex, or plano-conical; context unchanging, white to very pale buff; margin inflexed, appendiculate (less so in older specimens); universal veil on disc as conical to broadly conical warts, becoming smaller subfelted crumbs towards margin, becoming pale luteous, to ochraceous at tip. | ||||||||
lamellae | free, crowded very pale buff, 7 - 12 mm broad, with margin smooth to slightly floccose; lamellulae gradually attenuate. | ||||||||
stipe | 50 - 120 × 10 - 18 mm, surface above annulus floccose, striate, flushed rosy buff, below annulus fibrillose, pale luteous, becoming finely scaled towards base, with scales becoming larger at base, there slightly recurved, and palisade-like, usually flushed rosy buff; bulb 28 - 42 mm wide; context unchanging, white to very pale buff solid; partial veil membranous, striate, tearing unevenly, pale luteous; universal veil not described separately from stipe and bulb. | ||||||||
pileipellis | 85 - 140 µm thick, with slightly gelatinized suprapellis and dense, non-gelatinized subpellis. | ||||||||
basidia | 46 - 86 × 9 - 16 um, 4-spored; clamps not present. | ||||||||
universal veil | with elements having anticlinal orientation; filamentous hyphae abundant, branching, 5 - 17 µm wide; inflated cells ellipsoid to clavate, 8.5 - 159 × 8.5 - 68 µm, hyaline, becoming smaller towards tip of wart; clamps absent. | ||||||||
lamella edge tissue | inflated cells numerous, 18.5 - 48 × 14.5 - 32 µm, globose, clavate, sphaeropedunculate, hyaline. | ||||||||
basidiospores | From protolog (Ridley 1991): [85/8/-] 8 - 12 × (6.5-) 8 - 10.5 µm, (Q = 1.00 - 1.25 (-1.38); Q' = 1.09), hyaline, amyloid, globose to broadly ellipsoid (to ellipsoid); apiculus not described; contents not described; white in deposit. | ||||||||
ecology | From protolog (Ridley 1991): Solitary to subgregarious. Under Nothofagus menziesii, N. solandri var. solandri and N. truncata. Known from the southern North Island, and the northern South Island of New Zealand. | ||||||||

discussion | From protolog (Ridley 1991): Amanita pareparina is a member of subsection Solitariae of section and subgenus Lepidella as it lacks a membranous volva. Although clampless, attempts were made to key it out in both clamped and unclamped stirps (Bas 1969) without success. The species is distinctive with its pale luteous ochreous pileus, rosy-buff tinged stipe, firmly attached warts on the pileus, pileus flesh which cracks deeply to lift in to large, irregular fleshy scales, straight to slightly curved scales at the base of the stipe and a persistent annulus. | ||||||||

Each spore data set is intended to comprise a set of measurements from a single specimen made by a single observer; and explanations prepared for this site talk about specimen-observer pairs associated with each data set. Combining more data into a single data set is non-optimal because it obscures observer differences (which may be valuable for instructional purposes, for example) and may obscure instances in which a single collection inadvertently contains a mixture of taxa.
