Amanita ravenelii
''Amanita ravenelii'', commonly known as the pinecone Lepidella, is a species of fungus in the Amanitaceae family. The fruit bodies are medium to large, with caps up to wide, and a stem up to long and thick. The warts on the whitish cap surface are large—up to wide and 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, which have an odor resembling bleaching powder, are not recommended for consumption.
