Atheniella flavoalba, which has the recommended name of ivory bonnet in the UK, is a species of agaric in the family Cyphellaceae. The cap is initially conical, before becoming convex and then flat; it may reach up to 1.5 cm (0.6 in) across. The cap is ivory-white to yellowish white, sometimes more yellowish at the center. The tubular stems are up to 8 cm (3.1 in) long and 2.5 mm (0.10 in) thick, and have long, coarse white hairs at their bases. Atheniella flavoalba is found in Europe, the Middle East, and North America, where it grows scattered in pastures or in dense groups under conifers and on humus in oak woods.
