The spores of the present species measure 9.1 - 11.9
(-12.9) × (8.0-) 9.1 - 11.2 (-11.5) μm and are
globose to subglobose to broadly ellipsoid and
inamyloid. Clamps are not present at bases of
This species is known from a single collection found
in sandy clay under Loblolly Pine
(Pinus taeda) in Alabama.—R. E. Tulloss

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 derived from original
research by R. E. Tulloss.
67 - 101 mm wide, 5D4, 5C-D3, some with dark band over
inner ends of marginal striations, unchanging when
cut or bruised, convex to
plano-convex, umbonate, tacky; context
pale grayish brown under pileipellis in disc,
unchanging when cut or bruised, 4.5 - 10
mm thick, thinning evenly to margin; margin
nonappendiculate, striate (0.15 - 0.3% R);
universal veil usually absent, sometimes as
whitish soft thick patch with verruculose surface,
unchanging when cut or bruised.
free to narrowly adnate and infrequently with
line on stipe apex, crowded, whitish in mass and
white in side view; lamellulae truncate to
attenuate after a step,
125 - 168 × 8 - 12 mm, whitish to pallid,
faintly browning from handling, occasionally sinuate
in portion inserted in substrate, narrowing
flaring at apex, decorated with white pulverulence
above, with fine to coarse recurved scales below;
context hollow below, stuffed above, off-white
to faintly brownish, unchanging when cut or bruised,
larva tunnels not observed, with central cylinder 3.5
- 7.0 mm wide (0.45 - 0.6% of stipe width);
exannulate; universal veil as soft
fleshy white soft membranous saccate volva, sightly
flaring and filled with subsrate,
with distance from stipe
base to highest point on volval limb 22 - 34 mm, ca.
3 mm thick at mid-height, with small limbus internus
at point of connection of stipe and volval limb.
Odor faint or none. Taste
Paracresol spot test for tyrosinase - entire
cross-section of basidiome orange-brown (positive)
in 1 min. Syringaldazine spot test for
laccase - context of
universal veil and stipe base and base of stuffed
central cylinder of stipe strong lavender (positive)
after 13 mins. Test voucher:
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.
