Ripartites tricholoma, commonly known as the bearded seamine, is a species of fungus in the family Tricholomataceae.

It was first described scientifically as Agaricus tricholoma by Albertini and Lewis David von Schweinitz in 1805,[1] and later transferred into the genus Ripartites by Petter Karsten in 1879.

[2] It is found in North America and Europe,[3] and has also been collected in Costa Rica.

[4] This fungus is reminiscent of a Clitocybe, but the spore powder is light brown instead of white, and when young the cap rim is surrounded by spine-like hairs, which quickly disappear.

The gills are off-white and they are somewhat decurrent down the brownish stem, which has a white frosting ("pruina") when fresh.
