| 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 derived from (Wood
1997),
collection annotations and photographs of L.
Albertella, molecular studies of L. V. Kudzma, and
other original research of R. E. Tulloss. |
| pileus |
Wood (1997):
up to 80 mm wide, pallid gray to
mouse-gray, sometimes gray-brown (13-15A-B1-3,
10YR/4-5/1-2), hemispheric then convex to planar,
finally slightly concave, smooth, dry;
context not described; margin
pellucid-striate; universal veil as large
flat scale(s), white to pale gray (paler than
pileipellis).
RET: 118 mm wide, light
grayish brown to grayish brown, virgate, dry, smooth;
context white except for gray for
up to 2.5 mm below pileipellis, 6 mm thick above
stipe; margin tuberculate striate
(0.2-0.4R), nonappendiculate;
universal veil as
irregularly dispersed patches, grayish white,
moderately thick,
submembranous, with irregular outlines, detersile
at first, later bonded to pileipellis. |
| lamellae |
Wood (1997):
free, crowded, white to cream to grayish
cream, "thin," with edge distinctly gray and
"somewhat punctate"; lamellulae in "one
series."
RET: free to receding, crowded, grayish white in mass, white
toward pileus context and pale gray toward edge
in side view, 14 mm broad, broadest at ca.
two-thirds gill length from stipe,
having edge decorated with irregularly spaced
bits of black floccose-fibrillose
material; lamellulae predominantly truncate,
also ??, common
(not between every pair of lamellae), of diverse
lengths. [Note: Some bits of gill edge
material are left in vertical rows on the stem
forming the "punctation" reported by Wood.
See below.—ed.] |
| stipe |
Wood (1997):
up to 170 × 10 mm, pale gray-cream,
with "plentiful fine short hairs in small bundles
vaguely irregularly arranged but not in irregular
zones, rarely showing some degree of zones"[
??]; exannulate; universal veil
as saccate volva, proportionately large,
membranous, persisting,
usually distinctly colored in shades of gray,
rarely white.
RET: 77 × 16 mm, with white or
very nearly white ground, narrowing upward, not
flaring at apex, densely decorated with
fine vertical rows of gill edge material (pale gray
with occasional black flecks), with surface
decoration apparently becoming
blackish gray and some bits of lamella edge
material
becoming black (resulting in apparent punctation)
when handled ; context white,
stuffed with loosely interwoven white cottony
fibrils, with central cylinder
9 mm wide; exannulate;
universal veil as persistent saccate volva,
at first with upper part flaring widely (with
multiples subtriangular lobes),
at first white on outer surface and gray on inner
surface, remaining white on exterior of
lower portion, with upper portion becoming gray
on outer surface and weakening-collapsing
with age, with limbus internus not described. |

| discussion |
Apparently, the edge material of the lamellae
(including both tissue remaining on the gill edge and
material remaining on the stipe) is liable to
darkening/blackening after the expansion of the
basidiome separates the gill edges from the
stipe. The most(?) damaged bits of tissue
are blackest and in marked constrast to their
surroundings—yielding the apparent
"punctations" that were misinterpreted by
Wood (1997).
The present species seems to be distinguishable
from
A. cheelii
(≡A. punctata Clel. & Cheel) by spore
size.
The present species was briefly known on this site as "A. sp-AUS05." |
