| intro |
Tulloss believes that a case can be made that Wood (1997) combined two different taxa under the name A egregia. The single collection on which Wood based all his illustrations of the microscopic anatomy of A. egregia sensu A. E. Wodd and his illustration of a basidiome is USNW 84/305. Because of its status as the better documented of the two cited collections and because the illustrated spores are easily differentiated from the proportionately broader spores of A. egregia, this collection is chosen to represent Wood's concept. For the moment, please, refer to the technical tab. |

| intro |
Olive text indicates a specimen that has not beenthoroughly examined (for example, for microscopic details) and marks other places in the text where data is missing or uncertain. The following material selectively draws from the description for A. egregia by Wood (1997) and from original research by R. E. Tulloss. | ||||||||
| pileus | from Wood (1997): cream to somewhat dull cream, convex then flattened convex; context not described; margin striate "on outer quarter," decurved; universal veil as irregular white patches. | ||||||||
| lamellae | from Wood (1997): free, crowded, white, thin, with concolorous margin; lamellulae said to be absent. | ||||||||
| stipe | from Wood (1997): white, having scattered fine fibrils on surface; context not described; partial veil small, white, membranous, persistent, skirt-like, superior, slightly striate above; universal veil as saccate volva, proportionately rather short, white, membranous, possibly becoming fragile with age. [Note: incorrectly described as having a basal bulb on the stem.] | ||||||||
| odor/taste | neither recorded. | ||||||||
| macrochemical tests |
none recorded. | ||||||||
| basidiospores |
from measurements made on illustrations of properly aligned spores in (Wood, 1997: fig. 16d): [3/1/1] 10.1 - 11.4 × 6.8 - 8.2 μm, (Q = 1.38 - 1.50; Q = 1.44), ellipsoid, inamyloid; apiculus (per illustrations) sublateral, cylindric, proportionately robust; contents not reported; color in deposit not reported. [Note: It was assumed that all the spore drawings come from a single specimen of the collection, the size of which is not yet known to the ed.] Note: [The description of spores in the text (Wood, 1997: 756) does not match measurements made on the illustrated spores (Wood, 1997: fig. 16d).] Composite of data from all material revised by RET: [21/1/1] 9.2 - 12.6 (-13.0) × 6.6 - 9.4 (-9.6) μm, (L = 10.7 μm; W = 7.7 μm; Q = 1.28 - 1.52; Q = 1.39), ??, smooth, thin-walled, inamyloid, ellipsoid, occasionally broadly ellipsoid, often adaxially flattened; apiculus sublateral, cylindric, proportionately robust; contents ??; ?? 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.
