Ptomaphagus

Ptomaphagus er en slekt av mycelbiller som særlig finnes knyttet til sopp og åtsler.


== Utseende ==
Små  (2-4 millimeter), halvmatte, mørkbrunlige mycelbiller, kroppsformen nærmest dråpeformet med lange bein. Antennene er litt kølleformede og 11-leddete. De fem ytterste leddene danner en avlang klubbe, men det åttende leddet er mye mindre enn de andre og er vanligvis forkortet til en liten skive. Hodet er oftest kraftig innskåret bak fasettøynene, med en smal hals, men dette kan være vanskelig å se da billene gjerne trekker hodet inn under brystskjoldet. Hannen har utvidete føtter på forbeina.


== Levevis ==
Artene kan finnes på små åtsler, mellom råtnende plantemateriale og av og til i musereir.
