Features include nearly spherical to short-cylindric thick-walled nest with coarsely tomentose lid, exterior yellowish to tawny or cinnamon brown becoming whiter or darker, and velvety becoming smooth, interior whitish to grayish or pale brown and shiny smooth, eggs whitish to light brownish, attached by a papilla to a cord which is joined to the inside of the cup, and growth on sticks, plant debris or sometimes dung.
Eggs: 0.1-0.2cm across, several, circular but flattened (lens-like or disc-like), “usually attached to nest by long thin cords”; “whitish to buff or with a very slight brownish tinge”, (Arora), 0.04cm thick, frequently 0.14cm across, occasionally 0.16-0.20cm across, variable in size, even in the same cup, attached to cup by cord which attaches to a nipple-like protuberance on egg; pale ochraceous, later becoming white, (Brodie), 0.15cm across, white, attached to cup by long thin cord, (Phillips), 5-12 per cup, lens-shaped, attached by short thread; ocher, (Courtecuisse), attached by coiled cords, (Lincoff(2)), eggs develop and stay for some time in a gelatinous liquid, (Lincoff(1))
Outer Surface: yellowish or tawny to cinnamon brown, often darker or whiter when old; velvety or shaggy, becoming nearly smooth when old, (Arora), alutaceous-yellow, tawny-yellow, becoming white when old; velvety, becoming smooth when old, (Brodie), yellow ocher to tawny brown; velvety, (Phillips), yellowish gray-brown; +/- fibrillose, (Courtecuisse)
