The cheilocystidia ( cystidia on the gill edge ) have dimensions of 18 26 by 6 9 ?m, and a shape ranging from ventricose-rostrate ( broad in the middle and tapering to a beaklike neck ) to mucronate ( ending abruptly in a short sharp point ).

Spores are roughly elliptical to somewhat cylindrical, hyaline ( translucent ), and measure 5.5 10.5 by 3.5 4.5 utriform ( like a wineskin bottle ), to ventricose-rostrate ( where the basal and middle portions are swollen and the apex extends into a beak-like protrusion ).

Several genera exhibit unusual modifications to male antennae ( especially " Cryptolestes ", " Dysmerus ", and " Microbrontes " ), with the scape expanded into hook-like or blade-like structures Several other genera ( " Rhinomalus ", " Rhinophloeus ", and " Metaxyphloeus " ) related to " Laemophloeus " are atypical in that the adults are rostrate to varying degrees Photographs of most world genera are available at, and most North American species are pictured at,
