4. Amanita velatipes, Thompson Pond Preserve, Pine Plains, Dutchess Co., New York, U.S.A.
Amanita velatipes is a rather large species of the northeastern U.S.A. and southeastern Canada.
Its cap colors are often close to yellowish cream. The volva is usually distributed on the 80 - 120 mm wide cap as white warts.
The gills are free, crowded, and white to pale cream.
The stipe is up to 170 × 20 mm, has an interesting (often submedian) annulus that is pulled up into a funnel shape by the expansion of the mushroom, and has a volva that leaves a robust rolled rim around the top of the basal bulb.
According to Jenkins (1986) the spores measure 7.9 - 13.2 × 6.3 - 7.9 µm and are broadly ellipsoid to ellipsoid to elongate and inamyloid. Clamps are rarely found at bases of basidia.
Fruiting bodies of this species can be quite large—the larger of the "buttons" in the accompanying illustration was nearly as big as RET's fist.
The species is associated primarily with Oaks (Quercus) and conifers.
It appears to be restricted in range to eastern North America. Compare with A. multisquamosa Peck.—R. E. Tulloss

The editors of this site owe a great debt to Dr. Cornelis Bas
whose famous cigar box files of Amanita nomenclatural information
gathered over three or more decades were made available to RET for computerization
and make up the lion's share of the nomenclatural information presented on this site.
The following text may make multiple use of each data field.
The field may contain magenta text presenting data from a type study
and/or revision of other original material cited in the protolog of the present taxon.
Macroscopic descriptions in magenta are a combination of data from the protolog and
additional observations made on the exiccata during revision of the cited original
The same field may also contain black text, which is data from a revision of the present
taxon (including non-type material and/or material not cited in the protolog).
Paragraphs of black text will be labeled if further subdivision of
this text is appropriate.
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 macroscopic description is largely based on the protolog and the annotation deposited with the Bills collection at BPI. Microscopic detail comes from cited sources or (where citation is lacking) from original research of R. E. Tulloss.

up to 170 × 10 - 20, white to cream, with brownish yellow stains in age, longitudinally striate, fibrous to floccose-scaly, cylindric or narrowing upward slightly; bulb globose to napiform; context ?, stuffed at first with loose cottony fibrils, becoming hollow; partial veil membranous, skirt-like, often opening upward at first, submedian to inferior; universal veil ocreate, with limb well separated from stipe, thick, white, at top of bulb, occasionally with additional ring of material on stipe above limb.

The smallest (and narrowest) spores were encountered in Tulloss 7-10-90-H, which was immature when dried—even in the 20% of the gill length closest to the stipe, basidia were predominantly sterile.
In evaluating the collection in RET's herbarium as a group, a set of collections from Cumberland Co., Maine, U.S.A. stood out because of their unusually broad spores. These differed so greatly from the spores of the other material reviewed that we have segregated them for the moment—data from these collections is not included in the description above. The set of segregated collections is as follows:
MAINE—Cumberland Co. - Cumberland Center, 22.vii.1984 S. S. Ristich 7-22-84-SSRA (RET 113-7); Cumberland Center, Rte. 9, 25.vii.1984 S. S. Ristich 7-25-84-SSRA (RET 207-1), 28.vii.1984 S. S. Ristich 7-28-84-SSRA (RET 207-2); North Yarmouth, 5.viii.1990 S. S. Ristich s.n. [Tulloss 8-5-90-SSR1] (RET 477-5).
Spore data for the excluded collections is as follows:
We note that spore length hardly differs on average from spore length seen in the material determined with greater confidence to be A. velatipes. The sample size is small in both groupings. Also, neither group has been thoroughly evaluated anatomically.

can be found here.
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.
