Lentinellus ursinus is a species of fungus belonging to the family Auriscalpiaceae. ^[1]

The caps are 2–10 centimetres (1–4 in) wide, ^[2] often separated into lobes. They are brown in the center, fading to white at the margin. The spore print is white. ^[3]

It may require microscopy to distinguish from L. angustifolius. Lookalikes from other genera include Pleurotus ostreatus . ^[3]

It can be found in North America from October–March on the West Coast and July–October elsewhere. ^[3]

Like all species in its genus, it is inedible due to its bitterness. ^[4]
