| intro |
Upon first encountering this species in the field in Texas and in Connecticut it was noted to (often, but not always) have a darker cap than collections of Amanita sp-V03 and the taxon now called A. rhacopus. It was given a separate code number on the basis of the darker cap and what appeared to be larger spores. Since that time we have learned the the cap color is variable in these species and may not serve to separate them. For the moment, please see the technical tab of this page for more information that has not yet been digested for the brief tab. |
| cap | The tan to brown to grayish olive brown to dark gray brown cap is 76 - 100 mm wide. The cap edge is sometimes pale cream. The cap is cone-shaped at first, and becomes flattened with age; it is sometimes depressed over the center. The cap is tacky and dull to dry and shiny. The cap's flesh is 5 - 7 mm thick above the stem and white except for a pale brown to gray region below the cap's skin (about 1 - 2 mm thick). The flesh does not stain or bruise. The cap edge is grooved for a short distance. |
| gills | The off-white to pale gray gills are free to almost crowded and 6 - 9 mm broad. There may be a descending line on the upper stem. Infrequently a gill may fork toward the stem. The short gilss are unevenly distributed, end abruptly, and may have a tooth-like extension along the the underside of the cap. Short gills are plentiful and of varying lengths. They may be attached at the stem or the cap edge, or neither. |
| stem |
The stem has a white to pale ground color and is 99 - 146 x 10.5 - 15.0 mm. The stem may be white at its base and becomes pale brown with handling. The stem narrows upward and flares at its top and is often decorated with pale gray to brownish gray fibrils. The stem has three areas of surface decoration. The top most half of the stem is covered with white to pale gray powder, the middle area has lengthwise dense surface fibrils that become brown or gray with handling, the lowest area is white and sometimes has curving scales. The mostly hollow stem's flesh is white to pale tan. The volva is soft, smooth, and sack-like with a white exterior at first. The tissue of the upper part of the sack becomes gray to black and breaks into plaques and warts. The base of the sac tends to remain as a white cup enclosing the stem base. The latter is often separated from the dark volva fragments by a vertically grooved region often described as "strangulate." The uppermost point of the fragmented part of the volval is found 28 - 56 mm from the base of the stem. |
| odor/taste | The odor of this mushroom is minimal to slightly "fungoid unpleasant." |
| spores | The spores measure (9.8-) 10.0 - 12.0 (-13.1) × (9.1-) 9.5 - 11.5 (-12.9) µm, are globose to subglobose and inamyloid. Clamps are not to be found at bases of basidia. |
| discussion |
This species has been found growing alone or in small
groups. In Connecticut it was described in
moist sandy loam or loam of a coniferous or mixed
forest. In Texas it was found in a mixed
pine-hardwood forest or among native grasses in an
area with Pine, Sweetgum (Liquidambar
styraciflua), and Juniper. This species is similar to Amanita rhacopus. Connecticut material of this taxa was originally referred to the temporary code "sp-N34," which is no longer in use in these pages.—R. E. Tulloss, D. P. Lewis, and N. R. Goodman |

| 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 cited as the work of another researcher is based on the notes and photographs of collectors, molecular studies of Dr. L. V. Kudzma, and other original research by R. E. Tulloss and David P. Lewis. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

For sporograph comparisons with other A. rhacopus-like taxa from eastern North America, see the techtab of A. sp-V03. Multiple collections originally designated as "Amanita "sp. N34" or "sp. N45" have produced nrITS and/or nrLSU sequences that match sequences of the same loci derived from Texas material of A. texasorora. The original morphological concepts of both the Texas and Connecticut material involved a darker than usual cap in comparison to similar taxa such as A. sp-V03. However, the cap colors present on specimens of the present species have turned out to be quite variable—as in the case of A. rhacopus. Collections on this page are grouped by their nrITS and/or nrLSU sequences. This page contains material previously assigned to temporary code "A. sp-T01. Despite the great similarity between the nrITS of this species and that of A. sp-V03, they differ within the 5' 5.8S motif in one of the known variable characters. Since this is a rather conserved point in a nrITS sequence, this is unusual within a single species. Hence, we keep the two names as indicating separate taxa for the time being although phylogenetic separation is not strongly supported. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Spore data sets and their composite
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.
