Ciri dan struktur

The cap is 3-13 cm wide and, depending on its age, ranges in shape from egg-shaped to convex to somewhat flattened. The cap surface is smooth and white, sometimes with a pale tan- or cream-colored tint in the center. The surface is either dry or, when the environment is moist, slightly sticky. The flesh is thin and white, and does not change color when bruised. The volva is up to 3.8 cm in height (measured from the base of the bulb), and is about 2 mm thick midway between the top and the base attachment. The mushroom's odor has been described as "pleasant to somewhat nauseous", becoming more cloying as the fruit body ages. The cap flesh turns yellow when a solution of potassium hydroxide (KOH, 5–10%) is applied (a common chemical test used in mushroom identification). This characteristic chemical reaction is shared with A. ocreata and A. virosa, although some authors have expressed doubt about the identity of North American A. virosa, suggesting those collections may represent four-spored A. bisporigera. Tulloss suggests that reports of A. bisporigera that do not turn yellow with KOH were actually based on white forms of A. phalloides. Findings from the Chiricahua Mountains of Arizona and in central Mexico, although "nearly identical" to A. bisporigera, do not stain yellow with KOH; their taxonomic status has not been investigated in detail. The spore print of A. bisporigera, like most Amanita, is white. The spores are roughly spherical, thin-walled, hyaline (translucent), amyloid, and measure 7.8–9.6 by 7.0–9.0 μm. The cap cuticle is made of partially gelatinized, filamentous interwoven hyphae, 2–6 μm in diameter.

Ringkasan sumber

The mushroom has a smooth white cap that can reach up to 10 cm across and a stipe up to 14 cm tall with a white skirt-like ring near the top. The bulbous stipe base is covered with a membranous sac-like volva. The white gills are free from attachment to the stalk and crowded closely together. As the species name suggests, A. bisporigera typically bears two spores on the basidia, although this characteristic is not immutable. A. bisporigera closely resembles a few other white amanitas, including the equally deadly A. virosa and A. verna.
