This species, wdiich may be largo and heavy and can only be dislodged from 
trunks with ditficultv, is (juite common. It is a destiucti\e paiasite of foiest 
trees. Microscopic, '^examination for spores and setae is usually necessary to 
distinguish F. robustus (white spores and setae few or none) from F. setulosus 
(white spores, setae numerous) and F. rimosus (brown s])ores, no setae).
