| 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 text is based on original research by R. E. Tulloss. | ||||||||||||||||||||
| pileus | 60 - 75 mm wide, pale grayish brown to pale brownish gray with or without a faint band between inner ends of striations and disc or paler over striae or somewhat umbrinous over disc and otherwise gray, rounded conic, then planoconvex with low and broad umbo, lubricious to tacky, dull, disc faintly pubescent with drying; context white, sometimes faintly gray under pileipellis in disk, 4 mm thick at stipe, thinning evenly for one half to three-quarters of radius, then membranous to margin; margin striate (0.4R), sometimes striations becoming slightly tuberculate, nonappendiculate; universal veil absent or as scattered rather large white, membranous patches. | ||||||||||||||||||||
| lamellae | free, with or without faint and short decurrent line on upper stipe (lens), subcrowded, off white to pale cream to sordid cream in mass, white to pale cream in side view, drying pale orangish, 5.5 - 8 mm broad; lamellulae subtruncate to subattenuate (longer ones), unevenly distributed, sometimes in only two short ranks, sometimes rather sparse. | ||||||||||||||||||||
| stipe | 110 - 145 × 7 - 11 mm, white to chalky white, slightly darkening from handling, sometimes later becoming dark gray, finely pulverulent or satiny above and satiny and/or becoming fibrillose in lower two-thirds, fibrils becoming brownish gray, finely longitudinally striate, narrowing upward, flaring at apex; context white or whitish, unchanging or becoming slightly brownish when cut or bruised, with stuffed central cylinder sometimes watersoaked, becoming hollow with few remaining white fibrils, 2 - 3.5 mm wide; exannulate; universal veil as saccate volva, white, submembranous to membranous, smooth, soft, collapsed on stipe, tearing or cracking and breaking up into large patches, white, 35 - 55 mm from base of stipe to highest point of limb, 1± thick at midpoint between highest point of limb and point of limb separation from stipe, with limbus internus not described. | ||||||||||||||||||||
| odor/taste | Odor indistinct to faintly fungoid. Taste not recorded. | ||||||||||||||||||||
| basidiospores | [80/3/3] (7.2-) 8.5 - 11.2 (-12.2) × (6.0-) 7.5 - 10.0 (-11.2) µm, (L = 9.6 - 10.3 µm; L’ = 9.9 µm; W = 8.5 - 9.0 µm; W’ = 8.7 µm; Q = (1.02-) 1.07 - 1.22 (-1.26); Q = 1.13 - 1.14; Q’ = 1.14), hyaline, colorless, smooth, thin-walled, inamyloid, globose to subglobose to broadly ellipsoid, somewhat to distinctly adaxially flattened; apiculus sublateral, cylindrical to narrowly truncate conic; contents monoguttulate with or without small additional granules; white in deposit. | ||||||||||||||||||||

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.
