Pileus resupinate, dimidiate or cap-like, rarely volvate or annulate, fleshy, 

 leathery or woody, exceptionally waxy or gelatinous; hymenium concrete with the 

 hymenophore or readily separable from it, consisting of pores arranged regularly 

 or irregularly, sometimes lamelloid, very rarely rudimentary and reticulate; cystidia 

 often present, multiform; spores typically 1-celled, hyaline or colored.
