3. A. submaculata - Jamesburg Park, NJ RET
After more than 30 years of collecting in the eastern United States, RET has found only one entity
that could correspond to Peck's description of A. submaculata. Nevertheless,
because of the limited description of the present species (provided below), the
identification has not been formally published. The candidate has simply
been called "Amanita sp. 18" (Tulloss et al., 1995)
among other temporary designations.
The cap is 48 - 192 mm wide, grayish-brown to dark brown over the center, grayish brown to brownish or umbrinous gray to
umbrinous elsewhere, sometimes pallid at the margin, with appearance of having
brown or gray-brown innate fibrils, often with depigmented small spots
or short radial lines (hence Peck's epithet), at first often irregularly
rounded conic to irregularly convex to plano-convex to plane, with a
broad umbo, subshiny to shiny when dry, tacky to waxy when moist, with a
nonappendiculate and nonstriate margin (slightly striate, to 15% of the
radius with age), incurved at first, then down curved, finally straight.. The volva is absent
or present as irregular warts of varying size or filamentous thin
squamules, white or off-white or pallid becoming grayish or grayish
brown or brown, often over the center only, pulverulent, friable and
detersile.. The flesh is white, grayish at the center, 4 - 5 mm thick, thinning evenly to the margin,
and then membranous to the margin.
The gills are free to very narrowly adnate, subcrowded to crowded,
off-white to white to pale cream to cream, staining red brick, rounded
on the outer end, 4 - 8.5 mm broad, with or without a decurrent line on
the stipe apex.. The short gills are truncate to subtruncate to rounded truncate to
subattenuate to attenuate in steps, rather narrow, of diverse lengths,
some free from both the stem and margin.
The stem is (38-) 105 - 198 × (5.5-) 11.5 - 26 mm, slightly narrowing upward, flaring at the top, satiny white to
whitish to pale ground to blackish to brownish, pale orange-brown with
handling, sometimes with vertical red-brown dashes of staining on lower
stipe and upper bulb, sometimes sinuous, sparsely pulverulent above the
ring, satiny or fibrillose (sometimes coarsely squamulose) below partial
veil, with fibrils white or pallid in the topmost quarter of stem, brown
to gray brown below, with some fibrils becoming darker from handling,
with faintly longitudinally striations at maturity.. The bulb is (13-) 36 - 45 × (13-) 24 - 44 mm,
irregularly ovoid to fusiform to napiform to subnapiform, sometimes very small and
slender, staining brick red in old insect damage or staining with
red-brown marks.. The stem flesh is whitish to pale grayish cream, staining as in
other tissues, and solid.. The ring is white, sometimes brownish with age or staining brick red,
subapical to apical, superior, membranous, skirt-like (often suggesting
a broad, mid-19th Cent. ball gown), copious, striate
above, eventually collapsing on stipe, and tearing.. The volva is absent
or present as one or two thin whitish to gray rings around the top of the stipe's bulb
or as a loose limb against stipe or as loose patches easily overlooked
in the substrate, more membranous and more likely to be collected attached
to the specimen than in the case (for example) of Amanita
flavoconia G. F. Atk.
The species has a distinctive range of odors varying from fruit-like to anise-like, sometimes with both
elements present, sometimes with a chlorine-like addition.
The spores measure (6.3-) 7.0 - 9.8 (-13.3) × (4.5-) 4.9 - 6.6 (-8.4) µm and are broadly ellipsoid to
ellipsoid to elongate (rarely cylindric) and amyloid. Basidia lack clamps.
Originally collected in North Carolina where it was reported to occur scattered or clustered in "thin woods" and
"open places." In New Jersey it is often collected in Pine-Oak (Pinus-Quercus) barrens on sandy soil of the Atlantic Coastal Plain.
This species is often misidentified in North America. RET has been told that A. excelsa (Fr. : Fr.) Bertillon in Dechambre
has a fruity odor in North America, which is not true so far as we know. This error
is probably due to the confusion of A. submaculata, A.
morrisii Peck, and other often fruity-smelling taxa from the Americas, with the European species.
The information below is derived from the original description (Peck, 1900)
supplemented by the description of the type by Jenkins (1978).
The cap of Amanita submaculata is 70 - 90 mm wide, convex or somewhat bell-shaped, dark brown, more or less marked by whitish stripes or spots, and shiny when dry. The volval remnants are present as a single, floccose patch.
The gills are free, subdistant, white, and thin.
The stem is approximately 70 - 90 × 6 - 12mm, cylindric, white, and solid. The ring is large, white, flaring, very thin, persistent, and membranous. An ovoid bulb is present at the stem base without volval remnants.
In the original description, Peck says the specimen he was sent "yielded no spores." According to Jenkins' type study, the spores measure 7.0 - 8.6 × 4.7 - 6.4 µm and are broadly ellipsoid to ellipsoid to elongate and amyloid. Clamps are absent at bases of basidia.

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.
