| 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 (Pegler and Shah-Smith 1997). | ||||||||||||||||||||
| pileus | Pegler and Shah-Smith (1997): 55 - 65 mm wide, whitish to pale brown. broadly convex to applanate, depressed over disc, viscid; context not described; margin striate, undulate; universal veil as indefinite, concolorous squamules, becoming smaller and more fibrillose toward margin | ||||||||||||||||||||
| lamellae | Pegler and Shah-Smith (1997): free, crowded, white, drying brown, up to 6 mm broad, with denticulate edge; lamellulae "of three lengths." | ||||||||||||||||||||
| stipe | Pegler and Shah-Smith (1997): 60 - 65 (-90) × 7 - 10 mm, white, unchanging, cylindric or narrowing slightly upward, with withish to very pale brown to yellowish brown fibrillosed squamule; bulb lacking; context hollow; partial veil ephemeral, soon lost, reduced to faint annular zone on upper stipe; universal veil as saccate volva, fleshy-membranous, white, attached to stipe only at very base (per figure). | ||||||||||||||||||||
| odor/taste | Pegler and Shah-Smith (1997): Odor metallic. Taste not recorded. | ||||||||||||||||||||
| macrochemical tests |
not described. | ||||||||||||||||||||
| pileipellis | Pegler and Shah-Smith (1997): filamenous hyphae 4 - 5 μm wide, hyaline, thin-walled, "not agglutinated." | ||||||||||||||||||||
| pileus context | Pegler and Shah-Smith (1997): filamentous hyphae 2 - 6 μm wide; acrophysalides fusoid, up to 35 μm wide; clamps lacking. | ||||||||||||||||||||
| lamella trama | Pegler and Shah-Smith (1997): bilateral; filamentous hyphae of subhymenial base3 - 6 μm wide, with inflated elements up to 25 μm wide; clamps lacking. [Note: Inflated elements are not described as either intercalarly or terminal.—ed.] | ||||||||||||||||||||
| subhymenium | Pegler and Shah-Smith (1997): pseudoparenchymatous, 22 - 30 μm thick. | ||||||||||||||||||||
| basidia | Pegler and Shah-Smith (1997): 35 - 50 × 10 - 12 μm, 4-sterigmate; clamps not mentioned. | ||||||||||||||||||||
| universal veil | Pegler and Shah-Smith (1997): On pileus: present, but not described. On stipe base: filamentous hyphae 4 - 9 μm wide, interwoven; inflated cells absent. [Note: The description does not mention layering in the tissue. It should be rechecked for the presence of inflated elements.—ed.] | ||||||||||||||||||||
| stipe context | not described. | ||||||||||||||||||||
| partial veil | absent. | ||||||||||||||||||||
| lamella edge tissue | Pegler and Shah-Smith (1997): sterile. | ||||||||||||||||||||
| basidiospores | Pegler and Shah-Smith (1997): [-/-/1] 9.5 - 12 × 5 - 6 μm, (L' = 10.7 ± 0.9 μm; W' = 5.7 ± 0.32 μm; est. Q = 1.80 - 2.0; Q' = 1.89), hyaline, thin-walled, smooth (per figure), strongly amyloid, adaxially flattened (per figure); apiculus sublateral (per figure); contents refractive, monoguttulate (per figures), possibly with additional fine granules (per figures); white in deposit. [Note: A conservative range for Q is estimated because, without a range for Q, a sporograph cannot be generated.—ed.] | ||||||||||||||||||||

| discussion |
From the spore drawings of Gilbert (1940), one would expect the spore data for A. subviscosa to be the following: [8/1/1] 7.1 - 9.1 × 3.5 - 4.2 μm, (L = 8.2 μm; W = 3.9 μm; Q = 1.98 - 2.39; Q = 2.13). The length and width ranges are completely disjunct from the corresponding ranges provided for the present taxon. The following diagram provides a sporograph comparison of the two taxa. more t.b.d. | ||||||||||||||||||||

Spore data sets and their composite
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.
