context_page_description: Amanita ravenelii, commonly known as the pinecone Lepidella, is a species of fungus in the family Amanitaceae. The fruit bodies are medium to large, with caps up to 17 cm wide, and a stem up to 25 cm long and 3 cm thick. The warts on the whitish cap surface are large—up to 6 mm wide and 4 mm high. The stem has a large bulb at its base, covered with whitish to brownish scales, that may root several centimeters into the soil. The ring on the stem is thick and cotton- or felt-like. It is widely distributed in mixed and deciduous forests of the southeastern United States, where it grows solitarily or in groups on the ground in late summer and autumn. The mushrooms have a unique odor resembling bleaching powder.
context_section_description: The fruit bodies of A. ravenelii are distinguished from A. chlorinosma by the presence of pale yellow to brownish orange, large, conical to truncate-conical warts on the cap surface and a large basal bulb. The mushroom A. polypyramis is pure white, and lacks the pale yellow to brownish-orange large conical warts typical of A. ravenelii. The North American species A. armillariiformis has a similar areolate cap surface, but unlike A. ravenelii, does not have a distinct basal bulb, and it is found in semi-arid areas associated with aspen and old growth Douglas fir. Also from North America, A. mutabilis has pink tones on the cap and stem, and will turn pink when its flesh is cut; it smells of anise.
caption: The basal bulb is characteristic of A. ravenelii.
