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 on collectors' notes and photographs, molecular studies by Dr. L. V. Kudzma and other original research of R. E. Tulloss. | ||||||||||||||||||||||||||||||||||||||||||||||||
pileus | 72± mm wide, pale brown over margin, brown to dark brown over central umbo; context white, 7 mm thick over stipe, thinning evenly for two-thirds of cap radius, then membranous to margin: margin non-appendiculate, striate (0.3-0.35R); universal veil absent. | ||||||||||||||||||||||||||||||||||||||||||||||||
lamellae | free, crowded, off-white in mass, off-white to pale cream in side view, unchanging when bruised or cut, 6.5 mm broad, broadest at ca. 60% of length from stipe to margin; lamellulae truncate, of diverse lengths, plentiful, unevenly distributed. | ||||||||||||||||||||||||||||||||||||||||||||||||
stipe | 85 × 12.5 mm, pale gray in upper two-thirds, white below, narrowing upward, striate at apex; context stuffed, white, unchanging when cut or bruised, with central cylinder 4.5 mm wide, ??; exannulate; universal veil as white membranous-fleshy saccate volva, persistent, 33 × 20 mm, with free limb up to 1.5 mm thick and 23 mm long. | ||||||||||||||||||||||||||||||||||||||||||||||||
odor/taste | neither recorded. | ||||||||||||||||||||||||||||||||||||||||||||||||
macrochemical tests |
none recorded. | ||||||||||||||||||||||||||||||||||||||||||||||||
partial veil | absent. | ||||||||||||||||||||||||||||||||||||||||||||||||

discussion |
The three collections examined are quite consistent
with regard to nrITS and nrLSU sequences. In the field, this species was considered to be similar to A. penetratrix; however, the two taxa are genetically distinct. Among other things, the 5' terminal motif of nrLSU in the present species is the common one seen in nearly all species of Amanita, which is not the case in A. penetratrix. This page was formerly called "Amanita sp-N64." | ||||||||||||||||||||||||||||||||||||||||||||||||

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.
