≡Amanita pantherina var. pantherinoides (Murrill) Dav. T. Jenkins |
intro | The following description is based on Jenkins (1977), notes found with holotype, and data on recent collections. |
cap | The cap of Amanita pantherinoides is 30 - 100 mm wide, globose to hemispherical, becoming planar, honey-colored to dirty-cream colored with brown to chestnut to honey-tan in the center, viscid when wet, glabrous, with a faintly striate to nonstriate margin. The volval remnants are present as soft, small, white, floccose-fibrillose patches and warts, numerous and randomly distributed until falling away. The flesh is thin. |
gills | Gills are white, narrowly adnexed to free, when free, connected to the stem by an extremely heavy, floccose line, crowded; the short gills are truncate. |
stem | Its stem is 20 - 110 × 5 - 11 mm, tapering upward, often slightly expanded at the top, white to whitish, and stuffed to hollow, glabrous. The basal bulb is ovoid, white, smooth to minutely floccose. The ring is relatively large, white, superior, not apical, and persistent. The volva is present as a submembranous, short, thin limb around the stem base and/or as floccose material on the upper part of the bulb. |
odor/taste | No information is available about the odor or taste of this mushroom. |
spores | RET measured spores from three collections of this species including Murrill's type. The spores measure (8.1-) 8.5 - 11.2 (-12.2) × (6.0-) 6.3 - 7.7 (-8.5) µm and are mostly ellipsoid (with about 5% elongate and 5% broadly ellipsoid) and are inamyloid. Clamps are rarely present at bases of basidia. |
discussion |
Originally described from the state of Washington, USA under the two names cited at the top of the page. The synonymy was proposed by Jenkins (1977). This species was originally found under conifers and hardwoods in wet, coastal forests. Jenkins emphasizes the possibility of a close relationship between the present taxon and A. pantherina (DC. : Fr.) Krombh. The present taxon seems more gemmatoid than pantherinoid given the limbate volval remnants on the bulb and occasional clamp connections on basidia. I don't see a reason for it to be considered to be a variety of pantherina at the moment; however, I have not yet studied material of the present species in detail.—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 not directly from the protolog of the present taxon and not cited as the work of Dr. David T. Jenkins or another researcher is based on original research by R. E. Tulloss. | ||||||||

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.
