intro	The following data is from the description of Yang (1997).
cap	The fruiting bodies of A. lignitincta are small to medium-sized. Its undecorated cap is 40 - 60 mm wide, convex to plano-convex, and woody-brown to leather-brown, with the darkest region in the center. The center of the cap is often slightly depressed. The cap's margin is tuberculate-striate (extending 30% to 50% of the cap radius), and non-appendiculate, with a darker colored ring-like zone at the inner ends of the marginal striations. The cap's flesh is white and thin.
gills	The gills of this species are free, crowded to moderately crowded, and white. The short gills are squarely cut-off or nearly so.
stem	The ringless stem is 80 - 100 × 6 - 10 mm, nearly cylindric, grayish to dirty white, undecorated or bearing small fibrils, and hollow. Its flesh is white, no basal bulb is present on the stem. The volva is saccate, membranous, 20 - 35 mm high, 10 - 15 mm wide, and has both inner and outer surfaces white.
odor/taste	The odor is indistinct.
spores	The spores of this species measure (9.5-) 10.0 - 13.0 (-13.5) × (8.5-) 9.0 - 12.0 (-13.0) µm and are globose to subglobose and inamyloid. Clamps are not present at the bases of basidia.
discussion	Amanita lignitincta was tentatively described from Yunnan Province, China. It is not yet a well-known species; consequently, the name remains provisional.—Z.-L. Yang [Note: The reader may wish to compare the present species with A. umbrinolutea, the range of which is believe to extend from Europe into Himalayan India.—ed.]
