Amanita luteolovelata
D. A. Reid
Technical Description. (t.b.d.) BRIEF DESCRIPTION: The following is based on the original description of Reid (1980). The cap of A. luteolovelata is up to 50 mm wide, pale gray-brown, at first strongly convex, becoming flattened with a smooth margin. The cap is entirely covered with a pale yellowish, thin, felty-pulverulent layer of volval tissue which tends to form indistinct, cobwebby scales towards the center. The flesh is white. The gills are white. The stem is up to 40 x 10 mm, clavate, 15 mm at the base, white above, and creamy yellow below the ring. The ring is membranous, faintly striate, creamy yellow, and skirt-like. No volva is present at the stipe base. The flesh is white. The spores measure 7.0 - 9.2 x 5.0 - 7.2 µm and are broadly ellipsoid to ellipsoid and amyloid. Clamps are absent at base of basidia. Wood (1997) provides the following measurements: 7.5 - 10.5 x (5.6-) 6.0 - 7.8 µm (broadly ellipsoid to ellipsoid). Originally collected in Victoria, Australia. The taxon is also reported from New South Wales. Wood (1997) rejected Reid's reduction in rank of the present taxon, and I am in agreement on this point, although, since he may have misapplied the name A. grisella, our reasoning is somewhat different. The average spore of A. grisella E. J. Gilbert & Cleland is subglobose to broadly ellipsoid according to data presented by Reid as well as by my measurements of Gilbert's spore drawings. The spore width is proportionately smaller in A. grisella. It is odd that Reid did not make note of the difference in cap color between A. luteolovelata and A. grisella. Also, since the volva color in var. grisella is unknown, creating a variety based on volval color is unusual. -- R. E. Tulloss Return to Section Validae page. Last changed 27 December 2006. |
