| 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. |

| 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." |
