In this list of Amanita species, there are now 131? taxa of which 54? appear to be undescribed in the literature. Among the remaining 77? taxa there remains two (2) European names that are undoubtedly based on incorrect determinations found in older literature. We hope to purge incorrect determinations from the list eventually. At present, the names of concern are as follows (in the order in which they appear in the checklist): A. gemmata and A. spissa. At the moment, however, we retain them as a goad to reach for greater clarity.
With regard to supraspecific taxa, this document follows (Corner and Bas, 1962) and (Bas, 1969).
Many good collections probably representing material that should be added to this list are among the collections of A. H. Smith in MICH. This list does not yet include taxa from Texas recorded in A. H. Smith's Ms. treatment of Amanita in the US--another problem that needs to be rectified.
Symbol key: A ”+” after a taxon name indicates it was collected at the 10th Texas Mycological Society foray in the Big Thicket National Preserve (October, 1986). An "@" in a similar position means the taxon was collected at the July, 1987 NAMA Gulf Coast Foray in southern Louisiana and Mississippi. An "H" in a similar position means the taxon was collected at the December, 1989 Harrison (MS) foray of the Gulf Coast Mycological Society. A "!" in a similar position means that the taxon was collected at the June, 2000 NAMA foray.

The Thicket of Diversity project (Big Thicket All-Taxa Biodiversity Inventory) was initiated in 2007 by the Big Thicket Association. DPL is presently leader of the Fungus Taxonomic Working Group (TWIG) for this ATBI. Throughout this checklist, collecting site acronyms associated with the Thicket of Diversity project are in bold face type.

A number of collections sent to RET under this name in the past have proven to be A.

be as clearly understood as was thought in the recent past. Spores: [957/48/37] (7.5-) 9.0 - 12.8 (-

Colls.: RET 12-2-89-A, -B, -C
Locs.: M-HARC, M-HARS
Lit.: LMC81, JE86, TMS86
Apparently, the dominant muscarioid taxon of the southeastern USA.
In the northern limit of its known range, this
species overlaps with the range of the yellow muscarioid taxon of
northeastern North America presently
known as A. muscaria var.
guessowii. Very large collections (thousands of basidiomes) are
known from Harrison, MS site.
Spores: [327/16/11] (8.0-) 9.4 - 13.0 (-18.0) × (5.5-) 6.5 - 8.6 (-11.1)
µm, (L = (9.8-) 10.0 - 12.1 (-13.0) µm; L’ = 11.0 µm; W =

Spores: [40/2/1] (9.3-) 9.5 - 11.5 (- 12.0) × (6.5-) 6.8 - 8.0 (-9.3) ) µm, (L = 10.0 - 10.7 µm;
L' = 10.4 µm; W = 7.4 - 7.6 µm; W' = 7.5 µm; Q = (1.28-) 1.31 - 1.50 (-1.53);
Q = 1.37 - 1.41; Q' = 1.39). Dried material, photos, and information from Dr. Clark L.
Ovrebo (CSU) indicate that this taxon is present in eastern Oklahoma. Coker's collections were from
North Carolina. Jenkins [JE77] considered Schweinitz's name (A. pubescens) a nomen
dubium. Nevertheless, Coker supplies a very clear macroscopic description of the fungus to which he
applied Schweinitz's name. [ image ]

Pileus 42 mm wide, yellow to brownish yellow over disc, with white margin, not umbonate; margin striate

maryaliceae Tulloss nom. prov. !
Colls.: DPL 8075, RET 6-10-00-N
Locs.: MILC, RELS
Lit.: -
Pileus 50 - 90 mm wide, entirely white, unstaining, sometimes appear almost translucent,
5 - 6.5 mm thick over stipe, with universal veil as easily removed white warts, becoming grayish with
age.
Lamellae free to narrowly adnate, white in mass (sometimes slightly pinkish at first), white in side view,
3 - 7 mm broad;
lamellulae truncate to rounded truncate subtruncate to subattenuate to attenuate, sometimes adjacent to
stipe
rather than pileus margin, unevenly distributed, of diverse lengths, plentiful.
Stipe 57 - 135 × 5 - 12 mm, white, unchanging when cut or bruised, with bulb 22 - 42 × 14.5 - 21 mm,
subnapiform to subradicating,
partial veil apical to subapical, white; universal veil not evident or as detersile patch(es) easily left
in soil or in broken collars or irregular rows
(sometimes faint and sometimes suggesting the “collars” seen in A. muscaria), off-white to very pale
grayish, darkening in age.
Spores: [99/5/5] (6.3-) 7.0 - 9.0 (-9.5) µm, (L = 7.3 - 8.1 µm; L' = 7.8 µm; W = 5.3 -
5.7 µm; W' = 5.5 µm;
Q = (1.19-) 1.25 - 1.62 (-1.71); Q = 1.35 - 1.50; Q' = 1.42).
This undescribed species is known from as far
north as western Massachusetts and may occur as far south as the neovolcanic region of central
Mexico.
