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 derived from original research of R. E. Tulloss. | ||||||||
pileus | ?? - 84 mm wide, warm brown (7.5YR 3/4) over disc, elsewhere light to moderate orange-brown to orange-tan, planar, with pronounced umbo, dry, matte, somewhat like kid leather; context pale brown under pileipellis, else pale cream, unchanging when cut or bruised, 4.5 mm thick at stipe, thinning evenly to margin; margin striate (0.1R), nonappendiculate; universal veil absent. | ||||||||
lamellae | free with faint decurrent line on stipe, ??, tan with orange tint in mass, cream and partially watersoaked in side view, unchanging when cut or bruised, 7 mm broad, marginate here and there (apparently with margin concolorous with pileus); lamellulae truncate, unevenly distributed, of diverse lengths, plentiful, attached at stipe as well as at margin. | ||||||||
stipe | ?? - 115 × ?? - 10 mm, dingy cream, becoming brownish from handling, narrowing upward, not flaring at apex (even in age), finely fibrillose (10× lens), with fibrils concolorous with ground color, striatulate below; context pale cream to whitish, with grayish tints in stipe base, hollow above, stuffed in base with white cottony fibrils, with larva tunnels orange-brown (only noted as damage in upper central cylinder), with central cylinder 4 mm wide and running from pileus context to very base of stipe; exannulate; universal veil as saccate volva, membranous, white on exterior, with inner surface concolorous with pileus, with orange-rusty stains on exterior, moderately smooth, ?? × ?? mm, less than 1 mm thick; limbus internus not discerned in revised material (old). | ||||||||
odor/taste | Odor and taste not recorded. | ||||||||
macrochemical tests |
none recorded. | ||||||||
basidiospores | [20/1/1] 9.8 - 11.6 (-11.9) × (8.4-) 8.8 - 10.5 (-11.6) µm, (L = 10.7 µm; L’ = 10.7 µm; W = 9.8 µm; W’ = 9.8 µm; Q = (1.03-) 1.07 - 1.19 (-1.21); Q = 1.10; Q’ = ??), hyaline, colorless, thin-walled, smooth, inamyloid, subglobose to broadly ellipsoid, infrequently globose; apiculus sublateral, cylindric to truncate-conic; contents dominantly monoguttulate, with or without additional small granules; ?? in deposit. | ||||||||
ecology | Connecticut: Solitary. In dark loam and leaf litter of mixed woods including Quercus, Acer, Tsuga canadensis, and Pinus. | ||||||||

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.
