Cyptotrama asprata (alternatively spelled aspratum), commonly known as the golden-scruffy collybia[2] or spiny woodknight [3] is a saprobic species of mushroom in the family Physalacriaceae.

Widely distributed in tropical regions of the world, it is characterized by the bright orange to yellow cap that in young specimens is covered with tufts of fibrils resembling small spikes.

This species is differentiated from several other similar members of genus Cyptotrama by variations in cap color, and spore size and shape.

This species was first described from Ceylon by English naturalist Miles Joseph Berkeley in 1847;[4] soon after (1852), specimens were collected from South Carolina USA.

[10] As Canadian mycologists Redhead and Ginns explain in a 1980 article on the species, since its original 1847 description, C. asprata has been given 28 names, and placed in 14 different genera.

[14] It has been collected from Australia,[15] southeastern Canada,[16] China,[13][14] Costa Rica,[17] India,[18] Hawaii,[19] New Zealand,[20] Japan,[21] and the Russian Far East.
