           5. Stipe well-developed (up to 15 cm long, 4 cm thick) and densely coated with
               coarse white hairs, especially toward base....................................................... Lentinus levis

           5. Stipe absent or much smaller (up to 4 cm long), cap and stalk densely hairy
               and velvety, pinkish tan to reddish brown with violet tints, becoming pale
               ochraceous or tan with age ............................................................................Lentinus strigosus

1. Cap typically smooth, without conspicuous hairy or velvety areas although tufts of fibers, matted hairs, small
