    1. Amanita agglutinata, mid-Appalachian Mtns., Kentucky, U.S.A.

    • cap The cap of Amanita agglutinata is up to 40 mm wide, globose at first, finally plano-convex, viscid, pallid, pale yellow, nonappendiculate, and with a short striate margin. The volval remnants are off-white, rather prominent chunky warts that are easily removed when the cap is moist.
    gills Gills are crowded, free, white, broad, ventricose, and rounded near the stipe; the short gills are truncate.
    stem Its stem is 10 - 35 × 3 - 7 mm, tapering slightly upward, slightly expanded at the top of the stem, stuffed, and with a subfibrillose surface. The volva is appressed against the base of the stem.
    spores The spores measure 8.5 - 11 (-14.8) × (5.5-) 6.0 - 7.2 (-7.5) µm and are ellipsoid to elongate and are inamyloid.  The basidia lack clamps at their bases.
    discussion I have found this species only once and have merged the description with Jenkins'' description of the type collection.  The species is known from the southeastern U.S.  Apparently, it is rare or is rarely recognized.  The single collection of mine was made in an open forest with plentiful oaks.

    Descriptions of various mycologists that place the present species in section Amidella are in error because of the inamyloid spores of A. agglutinata.  Those who would place this species in section Vaginatae are in error because of the presence of a bulb at the stipe base.—R. E. Tulloss
