Spores: narrowly ellipsoid spores, 6.5--9 x 3--4.5 µm
Conservation Status: Not of concern
Edibility: Not edible
L. semitale is similar in color to the common brown forms of L. decastes, but is somewhat smaller, grows singly, in groups, or small clusters, and turns black in age or when bruised, although often the change is slow. It also has larger, narrowly ellipsoid spores, 6.5--9 x 3--4.5 µm. L. infumatum (Bresadola) Kühner is very similar with larger spores (9--11 x 5--6 µm) and white, instead of cream to grayish, gills. L. semitale is widely distributed in conifer forests and generally considered inedible.
