name | Amanita pyramidifera |
name status | nomen acceptum |
author | D. A. Reid |
english name | "Pyramid Builder Lepidella" |
intro |
The following description is based on Reid (1980). |
cap |
The cap of Amanita pyramidifera is 20 - 30 mm wide, plano-convex, grayish-buff, with a smooth margin. The cap is ornamented with very conspicuous, acutely conical or pyramidal warts up to 5 mm. |
gills |
The gills are white. |
stem |
The stem is 35 - 65 × 6 mm, whitish with a floccose covering below the ring disrupting into bands of tiny scales. The basal bulb is immarginate and up to 10 mm wide. The ring is distinct, cottony, and poorly developed. No volval remnants are present. |
spores |
The spores measure 8.0 - 13.5 × 7.0 - 9.0 µm and are broadly ellipsoid to ellipsoid and amyloid. Clamps are plentiful at bases of basidia. |
discussion |
This species was originally described from the state of Victoria, Australia. No ecological information was provided. Reid mentions possible confusion with Amanita farinacea (Cooke & Massee) Cleland & Cheel. Amanita farinacea differs in the structure of its volva and its having shorter spores and was placed in Bas' stirps Grossa, a group comprising entirely Australian taxa. Amanita pyramidifera does not fit precisely in any of the stirpes in the system of Bas (1969). The greatest similarity is possibly to stirps Virginea (see A. virginea Massee); however, the spores of species in this group are smaller and rounder than those of A. pyramidifera.—R. E. Tulloss |

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 material is derived from the protolog and from (Reid, 1980). | ||||||||
pileus | from protolog: 20 - 30 mm wide, grayish buff, plano-convex; context not described; margin "smooth and naked"; universal veil as very conspicuous, acutely conic or pyramidal warts up to 5 mm high, with faceted sides. | ||||||||
lamellae | from protolog: white. | ||||||||
stipe | from protolog: 35 - 65 × 6 mm, whitish, with floccose covering below partial veil disrupting into bands of tiny scales; bulb marginate, up to 10 mm wide; context not described; partial veil "poorly developed but distinct and cottony": universal veil "none." | ||||||||

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.
