| 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 based upon original research by R. E. Tulloss. | ||||||||||||||||||||
| pileus | 91 mm wide, deep brown with reddish tints, faintly to strongly virgate, planoconvex with broad umbo, dull; context white, slightly sordid in thin region below pileipellis, unchanging when cut or bruised, 8 mm thick at stipe, thinning evenly until 7 - 8 mm from margin, then membranous; margin striate (0.25R), nonappendiculate; universal veil absent. | ||||||||||||||||||||
| lamellae | free, without decurrent line on stipe apex, close to subcrowded, dirty cream in mass, cream in side view, unchanging when bruised or cut, 7 mm broad; lamellulae subtruncate, plentiful, of greatly varying length, irregularly distributed, some not attached to either margin or stipe. | ||||||||||||||||||||
| stipe | 181 × 16.5 mm, ground color pallid, with orange-brown to red-brown fibrils in chevron-like pattern below, grading into stippling toward the apex, narrowing upward, flaring slightly at apex, almost abruptly squared off at base, not staining or bruising; context pale off-white, unchanging when cut or bruised, concolorous in larva tunnels, hollow to stuffed, with some white cottony material in central cylinder that has diameter of 7.5 mm; exannulate; universal veil in submembranous gray patches distributed over lower one-third to one-half of stipe and often in two narrow rings with strangulate regions between them, with the lower of the rings very close to stipe base. | ||||||||||||||||||||
| odor/taste | Odorless. Taste not recorded. | ||||||||||||||||||||

| basidia | 47 - 66 × 13.2 - 19.2 µm, ?? | ||||||||||||||||||||
| basidiospores | [80/3/2] (8.2-) 9.0 - 14.0 (-15.5) × (8.0-) 8.5 - 13.5 (-15.0) µm, (L = 9.9 - 12.5 µm; L’ = 10.7 µm; W = 9.4 - 11.9 µm; W’ = 10.2 µm; Q = 1.0 - 1.10 (-1.22); Q = 1.05 - 1.06; Q’ = 1.05), hyaline, colorless, smooth, thin-walled, inamyloid, globose to subglobose, rarely broadly ellipsoid, often at least slightly adaxially flattened; apiculus sublateral, truncate-conic to narrowly truncate-conic; contents dominantly monoguttulate, occasionally granular; slightly off-white in deposit. | ||||||||||||||||||||

| discussion |
The values of L, W, L', and W' provided above for sp-N24 indicate that the set of spores for at least one collection was dominated by spores much larger than the spores measured from the other collections. Two different taxa could be involved or the data set may not be representative of typical spores in a mature fruiting body. These two collections should be individually compared with A. sp-N29 and A. sp-N32 in a thorough manner. 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.
