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 is based on molecular studies by L. V. Kudzma with other orginal research by R. E. Tulloss. | ||||||||||||||||
pileus | 45± mm wide, brown (ca. 2.5YR 4/2 or less red than 7E4), paler over disc, unchanging, ovoid at first then subcampanulate, dull, tacky; context very pale brownish, unchanging when cut or bruised, 1.5± mm thick over stipe, thinning evenly for two-thirds radius, then membranous to margin; margin striate (0.2 - 0.25R in young material), nonappendiculate; universal veil absent. | ||||||||||||||||
lamellae | free, lacking decurrent line on stipe apex, crowded, off-white in mass, very pale brownish white in side view, unchanging when cut or bruised, 2 - 3.5 mm broad; lamellulae truncate. | ||||||||||||||||
stipe | 42 × 7 mm, white, unchanging, narrowing upward, not flaring at apex, bearing fine white pulverulence; context very pale brownish white, unchanging, hollow, with central cylinder 2.5 mm wide, with insect tunnels concolorous to slightly browner; exannulate; universal veil saccate, with two main lobes, firmly membranous, with dry egg-shell texture on exterior, exterior white and having some brown stains and becoming more tannish with age, with edges of limbs soon gray and appearing to crumble, with interior surface browner from outset, with small limbus internus at line of attachment of stipe and volval limb. | ||||||||||||||||
odor/taste | Odor lacking. Taste not recorded. | ||||||||||||||||
macrochemical tests |
none recorded. | ||||||||||||||||
lamella edge tissue | sterile. | ||||||||||||||||
basidiospores | [20/1/1] (8.4-) 9.1 - 11.2 (-14.3) × (8.4-) 9.1 - 10.8 (-13.3) μm, (L = 10.4 μm; W = 9.9 μm; Q = 1.0 - 1.10 (-1.14); Q = 1.04), thin-walled, smooth, inamyloid, globose to subglobose, ??, with giant spores sometimes present; apiculus sublateral, cylindric; contents ??; color in deposit not recorded. | ||||||||||||||||
ecology | Solitary. In sandy loam or in sandy Pinus-Quercus barrens. | ||||||||||||||||

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.
