Scientific name: Laetiporus cincinnatus (Morgan)
Burdsall, Banik & T. J. Volk
Derivation of name: Laet- means "pleasing" or "bright";
por- means "pores;" cincinnatus refers to Cincinnati, Ohio,
the city near where the type specimen was
Synonymy: Polyporus cincinnatus Morgan; Polyporus
sulphureus var. semialbinus Peck; Polyporus sulphureus
var. overholtsii H.R. Rosen
Occurrence on wood substrate: Parasitic; rosettes form
on the ground (attached to roots)
at the base of
trees, particularly oak (Quercus);
Dimensions: Individual caps 3-25 cm wide, clustered to
form rosettes up to 45 (60) cm in diameter.
Upper surface: Pinkish-orange to pinkish-brown; radially
wrinkled; velvety to densely matted; dry.
Pore surface: Whitish.
Edibility: Edible, considered choice.
Comments: Unlike Laetiporus sulphureus, this species
grows on the ground in rosette-like clusters and has white
pores. Utilizing molecular techniques and mating
incompatibility studies, Burdsall and Banik (2001) recognize
L. cincinnatus as one of six species of Laetiporus in North
America, three of which occur in
