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 on original research of R. E. Tulloss. | ||||||||
pileus | ?? mm wide, Cream Color at first, rounded conic at first; context white, with Vinaceous Russet staining in larval tunnels, ?? mm thick above stipe; margin nonappendiculate, ??; universal veil as friable warts, yellow to strongly yellow (recorded in materials annotated as juvenile as well as full maturity material), becoming Walnut Brown. | ||||||||
stipe | ?? mm, white at first, bruising Vinaceous Russet, sometimes becoming shaggy; bulb only apparent as slight basal swelling of stipe, ??; context ??, white, bruising as in pileus; partial veil ??, membranous, skirt-like, sometimes entirely white, ??, sometimes with underside yellow and remaining so in mature specimen, ??; universal veil ??. | ||||||||
odor/taste | Odor lacking. Taste not recorded. | ||||||||
macrochemical tests |
none recorded. | ||||||||
subhymenium | pseudoparenchymatous (cellular); ??. | ||||||||
basidia | ??; clamps not observed. | ||||||||
lamella edge tissue | sterile. | ||||||||
basidiospores | RET: [40/2/2] (6.8-) 7.8 - 9.5 (-11.6) × (5.0-) 5.6 - 6.6 (-7.2) μm, (L = 8.2 - 9.0 μm; L' = 8.6 μm; W = 5.8 - 6.0 μm; W' = 5.9 μm; Q = (1.27-) 1.31 - 1.69 (-1.78); Q = 1.37 - 1.56; Q' = 1.46), colorless, hyaline, thin-walled, smooth, inamyloid, ellipsoid to elongate, rarely broadly ellipsoid, usually adaxially flattened; apiculus sublateral, cylindric, small; contents granular or mono- or occasionally multiguttulate with or without additional small granules; color in deposit not recorded. | ||||||||
ecology | Solitary. New Jersey: In typical Quercus-Pinus rigida barrens or in mixed deciduous forest (including Acer, Betula, Carpinus caroliniana, Carya ovata, Fagus grandifolia, Liquidambar styraciflua, and Quercus spp.). Rhode Island: In sandy soil of forest dominated by Pinus spp. and scrub Quercus spp. | ||||||||

discussion |
This species has strongly yellow universal veil
material in young specimens and, at least sometimes,
at maturity. Sometimes, the underside of the
partial veil is yellow. Another somewhat
similar taxon with yellow on the partial veil is
A.
aureosubucula. At the moment, this taxon is segregated solely by its nrITS and nrLSU sequences. In eastern North America, compare A. flavorubens, A. rubescens var. alba, Amanita submaculata, A. aureosubucula, A. sp-amerirubescens02, and A. sp-N47. The taxa with temporary code names of the form "sp-amerirubescens0X" (where "X" is an integer) were originally treated on this site as a single taxon "Amanita amerirubescens." The latter taxon page is maintained on the site and references collections still not divided among the temporary code names. | ||||||||

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.
