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. | ||||||||||||||||

inflated hyphal segments;
clamps not observed. RET: 56 - 73 × 14.9 - 16.2 μm, dominantly 4-sterigmate (infrequently 3-), with sterigmata up to ?? μm long, arising from ??; clamps not observed. | ||||||||||||||||
universal veil |

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." | ||||||||||||||||

Information to support the viewer in reading the content of "technical" tabs can be found here.
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.
