Ciri dan struktur
The cap is 3 to 10 cm in diameter and gray to grayish-brown in color; initially the cap is oval, then as it matures it becomes progressively conical, convex, and eventually flattened, sometimes with a small umbo (a rounded elevation in the center of the cap). The gills are white, free (not attached to the stem) to narrowly attached, moderately crowded together, and sometimes have a grayish tint; the lamellulae (small gills that run from the edge of the cap towards the stem) are truncate. The flesh is white and thin, and does not change color upon bruising. The stem is 8 to 22 cm long and 1 to 2 cm thick. Unlike many other Amanitas with stems that are swollen at the base (bulbous), the thickness of the stem is about the same at both ends. The stem surface is covered with a finely powdered bloom (pruinose), especially near the top; faint longitudinal lines may be seen. The variant A. vaginata var. alba is pure white, and has a volva that is either absent, or not constricted around the base of the stem. The spores are roughly spherical, 8–12 μm in diameter, thin-walled, and nonamyloid (that is, not absorbing iodine stain in Melzer's reagent). The pileipellis (cap cuticle) is composed of filamentous interwoven hyphae, 2–7 μm diameter, gelatinized. The spore-bearing cells, the basidia, are 36–52 by 4–13 μm, 4–sterigmate, without clamps. The volva is largely made of filamentous hyphae, 2–8 μm diameter, inflated cells broadly elliptic, elliptical, fusiform, to clavate, 40–85 by 10–35 μm, mostly terminal. The stem tissue is made up of filamentous hyphae with diameters of 2–6 μm; the inflated cells are terminal, club-shaped, longitudinally oriented, with dimensions of up to 289 by 31 μm.
Habitat dan peran ekologis
Spesies ini tersebar luas di Amerika Utara. Ia juga ditemukan di Azores, Australia, Iran and Skotlandia. A mycorrhizal species, A. vaginata grows singly or numerous in both coniferous and hardwood forests. Hal ini juga telah dicatat sering terjadi di daerah rumput di tepi hutan, rumput yang tidak dijaga, dan daerah pinggiran kota di mana tanah baru-baru ini terganggu. Spesies yang tersebar luas dan umum, bermunculan dari musim semi sampai musim gugur. Spesies ini telah tercatat sebagai makanan terkadang dari orang dewasa kumbang menggemparkan Tritoma biguttata biguttata, T.erythrocephala dan T.humeralis (yang mungkin bersifat konspesif), dan T.mimetica. One field panduan mencatat bahwa sapi menikmati makan jamur ini.
