≡Amanita vaginata var. elongata Kärcher. 1988. Doc. Mycol. 19(74): 53, fig. (on p. 55).
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.
Due to delays in data processing at GenBank, some accession numbers may lead to dead pages.
These pages will eventually be made live, so try again later.

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 material is derived from the protolog of the present taxon.
from protolog: 50 - 80 (-100) mm wide, gray-brown to brownish ochre to brownish hazel often becoming paler with time, ovoid-hemispheric at first becoming campanulate-conic with distinct umbo, later more or less broadly convex, shiny or viscid, more or less pruinose, sometimes rugulose; context white; margin long-striate-sulcate; universal veil absent.
from protolog: separation from stipe not described, crowded, white, rather broad, with edge concolorous and more or less crenulate; lamellulae not described.
from protolog: 150 - 230 × 10 - 20 (-25) mm, white, more or less silky, sometimes slightly grayish above, more or less flocculose below, deeply inserted in substrate (often difficult to extract without ruining stipe and/or universal veil); context at first stuffed, then quickly hollow in broad central cylinder; exannulate (per figure); universal veil as saccate volva, up to 50 mm high, moderately (ca. 3 mm) thick, membranous (per figure), bilobate, with obconic base, smooth, with exterior tinted more or less brownish ochraceous.
from protolog: Odor and taste not distinctive.
from protolog: Phenol - on context, reddish brown after 5 min.
from protolog: 4-sterigmate.
from protolog: On stipe base, "exterior" layer: filamentous hyphae 2 -3 μm wide, irregularly entangled; inflated cells infrequent, scattered, langeniform or pyriform or elongate-clavate, 40 - 60 (-80) × 15 - 30 (-40) μm always isolated.
from protolog: [-/-/-] 10 - 14 (-15.5) × 10 - 14 (-15.5) μm wide, (Q = 1.0 - 1.05), smooth, inamyloid, "absolutely spherical"; apiculus well-developed; contents "without inclusions"; white in deposit. [Note: If a value of 1.05 was obtained for Q of one or more spores, then it is not the case that spores are always isodiametric. Hence, we have chosen to present the spore measurements with equal ranges of length and width to generate an approximate sporograph.—ed.]
from protolog: On clayey soil, "associated with Casatanea sativa and probably related trees (Fagus, Quercus)."
from protolog: GERMANY: HESSE—ca. Frankfurt-am-Maine, Taunus Mtns., ?18.vii.1981 R. Kärcher 18-07-81 (holotype, in herb. R. Kärcher => FR F200).
Kärcher and Contu (1999): AUSTRIA: Karnten, ca. St. Veit, s.d. R. Kärcher s.n. (in herb. Kärcher => FR F210). GERMANY: HESSE—Hochtaunus - ca. Kronberg, s.d. R. Kärcher s.n. (in herb. Kärcher => FR F201). RHEINLAND-PFALZ—Vulkaneifel - "Nerother Kopf," s.d. R. Kärcher s.n. (in herb. Kärcher => FR F202). THURINGEN—Ilm - ca. Arnstadt NSG "Hain," s.d. R. Kärcher s.n. (in herb. Kärcher => FR F203).
SPAIN: CATALUÑA—Girona - Alt Empordà (Ampurdan), ca. La Vajol, s.d. R. Kärcher s.n. (in herb. Kärcher => FR F211). ITALY: SARDINIA—Prov. Sassari - S. Bachisio, Baldo, Tempio Pausania to Oschiri rd., 15.x.1998 M. Contu s.n. (?in herb. Contu), 8.xi.1998 G. Fancellu & A. Galbusera s.n. (?in herb. Contu).
While no collections other than the holotype are cited in the protolog, other stations are provided in which what is assumed to be the same species have been observed—in Austria, Germany, and Spain. Collections from these countries and from Sardinia are listed in (Kärcher and Contu 1999). Because the latter authors persisted in the idea that the species collected was related to A. malleata (under diverse names), we cannot be sure whether the non-type material is all contaxic. Revision is necessary.
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.
