context_page_description: Amanita flavoconia, commonly known as yellow patches, yellow wart, orange Amanita, or yellow-dust Amanita, is a species of mushroom in the family Amanitaceae. It has an orangish-yellow cap with yellowish-orange patches or warts, a yellowish-orange annulus, and a white to orange stem. Common and widespread throughout eastern North America, Amanita flavoconia grows on the ground in broad-leaved and mixed forests, especially in mycorrhizal association with hemlock.
context_section_description: The cap is initially ovoid in shape, but in maturity becomes convex and eventually flattened. Orange to bright yellow-orange in color, it reaches diameters of 3 to 9 cm (1.2 to 3.5 in). Young specimens are covered with chrome yellow warts that may be easily rubbed off or washed away with rain.
  The cap surface is smooth and sticky (viscid) beneath the warts; the edge of the cap is striate, reflecting the arrangement of the gills underneath. The flesh is white. The gills are barely free from the stem, and packed close together. They are white or tinged yellow on the edges, and initially covered with a yellowish partial veil. The stem is typically 5.5 to 11.5 cm (2.2 to 4.5 in) long by 0.7 to 1.4 cm (0.3 to 0.6 in) thick, equal or slightly tapered upward from a small rounded bulb at the base. Its color may range from white to yellowish orange, and the surface may be smooth, or covered with small flakes. The base of the stem usually has chrome yellow flakes of universal veil material adhering loosely to the bulb, or in the soil around the base. The partial veil leaves a skirt-like ring, (annulus) on the upper stem. The spore print of A. flavoconia is white.
  Campbell and Petersen published a detailed description of the characteristics of A. flavoconia grown in culture. In the era prior to the commonplace use of DNA analysis and phylogenetics, cultural characters were often used to help provide additional taxonomic information; they found considerable variability between different isolates.
  Two variants have been reported from Colombia, collected from Quercus humboldtii forests: A. flavoconia var. sinapicolor and var. inquinata.
  As the edibility of this species is unknown, it should not be consumed.
