etymology |
In honor of the extraordinary collector, Connie
Borodenko. At NEMF, NAMA, COMA, and other forays she has an extraordinary eye for novel and rare species of Amanita. She has contributed many fine specimens to the Roosevelt herbarium. She was an early collector of Amanita penetratrix and made the first (life size) drawings of the species. Her care in extracting the entire stem and volva of her specimen (of which the stipe extended 20 cm in to the ground) was remarkable—especially since the species was unknown and, consequently, she had no idea of the task ahead when she began to dig. | ||||||||

intro |
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 upon original research by R. E. Tulloss. | ||||||||
basidiospores | [75/4/3] (8.4-) 9.2 - 11.5 (-12.8) × (5.9-) 6.2 - 7.2 (-7.3) μm, (L = 9.9 - 10.6 μm; L' = 10.2 μm; W = 6.6 - 6.8 μm; W' = 6.6 μm; Q = (1.30-) 1.38 - 1.70 (-1.82); Q = 1.47 - 1.61; Q' = 1.54), hyaline, colorless, smooth, thin-walled, inamyloid, ellipsoid to elongate, ??; apiculus sublateral, truncate-conic to cylindric; contents monoguttulate; ?? in deposit. | ||||||||

discussion |
One of the means of distinguishing this entity from the Amanita jacksonii-like taxa of the eastern U.S.A. is the lack of an umbo on the pileus. It also appears that the cap color is more strongly orange than in A. banningiana, which, however, has spore size and shape similar to those of the present species. Also instructive is the comparison of sporographs is provided below. Some preliminary DNA work indicated that this species was distinct from A. banningiana; however, the results were apparently not retained by the lab doing the work. Fresh material of this taxon is greatly desired by the editors and their colleagues. The present species was formerly known as Amanita sp-N12 in these pages. | ||||||||

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.
