≡Amanitopsis vaginata var. punctata (Cleland & Cheel) E.-J. Gilbert
1. Amanita punctata, monochrome copy of a Cleland plate, South Australia, Australia.
The information below is based on the original publication of Amanitopsis punctata and orginal research of RET.
cheelii is up to 87 mm wide, at first globose, then
convex, sometimes gibbous, then planar to slightly
depressed, smooth, slightly sticky when moist,
nonappendiculate, with a markedly striate to sulcate and
rather short margin. The cap is very dark gray to grayish
brown to smoke gray, and is darkest over the disc. The
volva is present as occasional patches (especially in
young material), with most of them near the margin.
The gills are just free, with
rather long decurrent lines on the stem apex, close,
grayish white to very pale smoke gray, with edge darker,
and finely decorated. Short gills are apparently absent.
The stem is 100 - 130 × 13±
mm, ground color, slightly narrowing upward, finely
striate, finely spotted with grayish fibrous squamules,
exannulate, with hollow flesh. The saccate volva is
sheathing, ample, and grayish lead color. According to
the illustration in the original description, the
discoloring of the volval sac is dominate in the upper
part of the free limb (see above).
Odor and taste were not recorded.
The spores measure (10.5-) 11.7 -
15.6 (-21) × (9.9-) 11.4 - 14.7 (-20) µm and are globose
to subglobose and inamyloid. Clamps were unobservable at
bases of basidia in the lectotype and all paratype
The species was described from the
state of South Australia, Australia. In numerous modern
references to A. cheelii, a species with a brown
or red-brown cap (not gray) is depicted and significantly
smaller spores are reported. It is very likely that such
taxa or such a taxon depicted in east Asian and
Australian works under the name "A. punctata"
is not the present species. The species presented under the
present name by Wood (1997) with a pallid gray to mouse gray to
occasionally gray-brown cap, with large white (not lead colored)
patches of volva on the cap, and strongly globose spores for the most
part less than12 µm long involves a misapplication of the present
name (Note: the spores depicted in Wood's illustrations are not all
globose. Indeed, some are broadly ellipsoid.).
The graying gills and volva suggest
a relationship with species such as the group similar to A. submembranacea (Bon) Gröger, not infrequent in the Northern Hemisphere.

The following text may make multiple use of each data field.
The field may contain magenta text representing a type study
The same field may also contain black text, which will represent a revision of the
species by Tulloss. 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 poor to very poor condition of the material examined probably means that the cited upper limit of the size range of some elements (particularly acrophysalides) may be too low. The best preserved syntype found is Cleland 174 (BPI). The macroscopic description of the protolog is expanded by inclusion of information from Cleland’s notes deposited with his collections.
The following is based upon original research by R. E. Tulloss.
type study of RET: up to 87 mm wide, very dark gray to grayish brown (or smoky brown) to smoke gray (pl 363, Ton 3 or 4) or lead colored, darkest over disc, at first globose, then convex, sometimes gibbous, then planar to slightly depressed, smooth, slightly sticky when moist; context not recorded; margin markedly striate to sulcate and rather short (0.2R - 0.3R in exsiccata), nonappendiculate; universal veil as occasional patches (especially in young material), most often near margin.
type study of RET: just free with rather long decurrent lines on stipe apex (observable in exsiccatum), close, grayish white to very pale smoke gray, with edge darker (observable without magnification in exsiccatum of Cleland 174) and finely serrate; lamellulae apparently absent (Cleland 174).
type study of RET: 100 - 130 × 13± mm, ground color mentioned in protolog (gray per note with Cleland 9259), slightly narrowing upward, finely striate, finely spotted with grayish [smoke gray (pl. 363, Ton 4)] fibrous squamules, becoming longitudinally oriented below ("striae" per protolog) or with fine dark cobweb-like fibrils; context hollow, with some "pith" (latter not evident in cross section of pileus and stipe apex on pl. 28 in protolog); exannulate; universal veil as saccate volva, sheathing, ample, grayish lead color (pl. 363, Ton 1).
type study of RET: gelatinized just at surface or with shallow suprapellis 10 - 25 µm thick of largely gelatinized colorless hyphae, with ungelatinized region (i.e., subpellis when suprapellis developed) 55 - 70 µm thick of ungelatinized hyphae, yellow-brown to orange-brown; filamentous, undifferentiated hyphae 1.5 - 9.5 µm wide, branching, in fascicles or singly, in somewhat open criss-cross weave; vascular hyphae 4.0 - 19.0 µm wide, branching, rather common, sinuous, with lumpy outline.
type study of RET: filamentous, undifferentiated hyphae 2.0 - 10.5 µm wide, branching, plentiful, singly and in fascicles in open lattice structure; acrophysalides plentiful, thin-walled, clavate to narrowly clavate, up to 156 × 53 µm; vascular hyphae 3.8 - 15.0 µm wide, branching, scattered.
type study of RET: bilateral, almost entirely collapsed with central stratum not clearly distinguishable (Cleland 174); subhymenial base not distinguishable; filamentous, undifferentiated hyphae 3.0 - 8.8 µm wide, branching; terminal, inflated cells not observed (but tissues in bad condition); vascular hyphae not observed.
type study of RET: nearly completely destroyed by mold but possibly with basidia arising from uninflated hyphal segments in some regions in Cleland 174.
type study of RET: (41?-) 51 - 75 × 12.0 - 16.5 µm, dominantly 4-sterigmate, also occasionally 2- or 1-sterigmate, with sterigmata up to 9.0 × 2.8 µm; clamps unobservable due to state of tissue.
type study of RET: On pileus: absent on material examined. On stipe base, exterior surface: thin layer of filamentous, undifferentiated hyphae 1.2 - 4.0 µm wide, collapsed and partially gelatinized, branching, in fascicles, colorless near very base of stipe, orangish brown (and more gelatinized) higher on limb; vascular hyphae not observed. On stipe base, interior: filamentous, undifferentiated hyphae 2.0 - 5.8 µm wide, branching, in fascicles or singly, plentiful, forming very open lattice around inflated cells; inflated cells plentiful to dominant, colorless very near stipe base, pale gray to pale brownish gray higher in limb, terminal, thin-walled, subglobose to pyriform to ellipsoid to clavate, up to 52 × 28 µm; vascular hyphae not observed. On stipe base, inner surface: like interior, but slightly more gelatinized
type study of RET: longitudinally acrophysalidic; filamentous, undifferentiated hyphae 3.5 - 15.0 µm wide, branching, plentiful to dominant; acrophysalides plentiful, thin-walled, up to 165 × 38 µm; vascular hyphae not observed.
lamella edge tissue
type study of RET: yellow to yellow-orange, strongly contrasting with face of lamella, all elements partially gelatinized and collapsing; filamentous, undifferentiated hyphae plentiful, with periclinal orientation, intertwined; inflated cells in two to three layers, apparently terminal, up to 29 × 22 µm.
type study of RET: Usually solitary, occasionally in twos or threes. Type collected after heavy rain.
type study of RET: AUSTRALIA: NEW SOUTH WALES—Mosman 7.iv.1918 J. B. Cleland s.n. (syntype, ADW 9576 => AD 3283, marked "type" in Cleland’s hand); Sydney, s.d. J. B. Cleland 174 p.p. (syntype, BPI 751249, mixed collection marked "co-type" in Cleland’s hand); Sydney, Bradley Head, 6.v.1917 J. B. Cleland s.n. (lectotype, ADW 9259 => AD, marked "co-type" in Cleland’s hand), 31.iii.1919 J. B. Cleland s.n. (syntype, ADW 9578 => AD 3284, marked "type" in Cleland’s hand), 12.iv.1919 J. B. Cleland s.n. (syntype, ADW 9575 => AD 3280); Sydney, Neutral Bay, Athol Gardens, 7.iii.1916 J. B. Cleland s.n. (syntype, ADW 9577 => AD 3285).
The plate in the protolog shows (on a mature basidiome) a cracking volval limb that is much darker in its upper portion than at the stipe base.
Smaller spored collections assigned to this species by Reid (1980: 51), Young (1986 & 1994), and Wood (1997) may not be contaxic with the New South Wales material collected by Cleland. Fuhrer (1985: 19) depicted a species with a volva that does not appear to be very gray and is constricted below and flaring above in the manner typical of numerous taxa of section Vaginatae [e.g., A. supravolvata Lanne (Tulloss, 1994)]. Ridley (1991) reported that Fuhrer had agreed with him that the depicted fungus was not assignable to A. cheelii. My spore data agree well with the protolog, where it is stated that the spores are "thick-walled, 10.4 to 14 µm, occasionally 17 or 18 µm."
Reid (1980) designated the lectotype without any explanation as to why the particular syntype was chosen. It would have been helpful to do so because a single collection (J. B. Cleland 165 with watercolor by D. I. C[larke?]. numbered 62) apparently preserved in formalin is specifically listed (without qualification as type) in the protolog and must be considered an implicit holotype (ICBN §7.3) if it can be located. This collection and/or the water color are mentioned on slips of paper in Cleland’s hand in the packets of AD 3283 and AD 3285 in context suggesting that Cleland 165 and the watercolor were considered as the foundation of his concept of the present species. Reid does not state whether Cleland 165 still exists. Searches at my request at AD, ADW, K, and PC did not uncover this collection. It may have been lost.
Cleland 174 is a mixed collection. The portion at BPI includes one half of a longitudinally sectioned basidiome of A. cheelii and portions of two very small basidiomes that apparently belong in the Russulaceae.
Cleland and Cheel (1919) designated the color “smoke-grey” to be equivalent to "pl. 313, Ton 4" of Dauthenay (1905). This is a typographical error. That color is a dark ocher labeled "nuance observée sur la Polyporus sulfureus." "Smoke grey" is the name applied to the colors of pl. 363. On slips of paper bearing descriptions of the fresh material of AD 3280 and AD 3283, Cleland records the color as "363-4" and "363 Ton 3 or 4" respectively. The color of pl. 363, Ton 4 is close to 5E3; but the Methuen color chip does not have quite strong enough a red component. 5E4 is more yellow than pl. 363, Ton 4.
The material of AD 3283 is in very bad condition because of the attack of a mold. In the one mount attempted, I could not find sufficient undamaged spores to justify inclusion of their measurements in the data presented above.
The name of the present species is commonly misapplied to one or more species with, among other things, smaller spores.
There appears to be a prior homonym for this name—Amanita puncata Lam. (1783).—R. E. Tulloss

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.
