name status | nomen acceptum |
author | A. E. Wood |
english name | "Wood's Graying Lepidella" |
intro |
The following is largely based on the original description (Wood 1997). |
cap |
The cap of Amanita cinerascens is up to 80 mm wide, convex then plane, smooth, dry, sometimes slightly viscid, pallid cream to cream-buff or buff-gray, with a nonstriate margin [possibly appendiculate?]. Volval remains are present as rather fine but prominent, pyramidal warts, less distinct on the outer parts of the cap, usually a little paler than the cap color. |
gills |
The gills are free, thin, crowded, white to pale cream, occasionally with some pink tint, with a mostly white edge. The short gills are present in at least two series. |
stem |
The stem is up to 100 × 10 mm, white above and more or less cream below, smooth above, slightly finely fibrillose below. The ring is large, submembranous, white to cream to somewhat gray, skirt-like, striate above, occasionally sufficiently fragile to break up and fall away. The bulb is top-shaped to turnip-shaped, white, with sparse, usually grayish, irregular zones and scales of volval material on the upper part. |
spores |
The spores measure (7.8-) 9.6 - 12.3 × (5.2-) 6.0 - 8.1 (-9.0) µm and are ellipsoid to elongate and amyloid. Clamps are plentiful at bases of basidia. |
discussion |
Wood describes the mushroom as occurring in sclerophyll forests from the state of New South Wales, Australia. A sclerophyll forest in the Australian bush is a forest of hard-leaved plants including Eucalyptus in the overstory (wikipedia). This species is placed in section Validae by Wood, however, it belongs in section Lepidella by the same argument given in the case of Amanita elongatispora A. E. Wood. According to Wood's description and the key of Bas (1969) the most probable placement for Amanita cinerascens is in stirps Daucipes.—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 of this species, which does not meet contemporary standards for Amanita taxonomy. | ||||||||

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.
