name status | nomen acceptum |
author | A. E. Wood |
english name | "Shadow of a Straw Lepidella" |
intro | The following is largely based on the original description (Wood 1997). |
cap | The cap of Amanita allostraminea is up to 120 mm wide, white to ivory, convex to plane, smooth, dry, with a nonstriate and not clearly appendiculate margin. The cap is decorated with small, flat, low, membranous scales on the outer part; the scales are concolorous with the cap. |
gills | The gills are free, thick, subdistant, deep cream, with a concolorous margin. Short gills are present in at least one series. |
stem | The stem is up to 140 × 20 mm, equal, smooth, and white to off-white. The ring is prominent, persistent, membranous, skirt-like, cream, and not striate on the upper surface. The base is bulbous to slightly top-shaped, white with scattered concentric rings of volval remains. Wood states it also bears "scattered buff marks." |
odor/taste | Odor and taste were not described for this species. |
spores | The spores measure 9.9 - 11.4 (-13.5) × 8.4 - 10.5 (-11.1) µm and are subglobose to broadly ellipsoid and amyloid. Clamps are sparse to rare at bases of basidia. |
discussion |
Wood describes this species from New South Wales, Australia as occurring in association with Allocasuarina. So far as we know, this species is known only from the type specimen. As Wood states, more material of this species is necessary to truly understand the microscopic anatomy and proper systematic placement. One curiosity is his description of the volva as having an upper layer dominated by inflated cells and a lower level dominated by hyphae. This form of volva is not typical of stirps Grossa, and, if confirmed for this species, suggests possible placement in either stirps Ravenelii, or stirps Solitaria.—R. E. Tulloss and L. Possiel |

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 based entirely on the protolog. | ||||||||

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.
