Hemitrichia is a genus of slime molds, of the family Trichiaceae, found within the order Trichiida. It was first described by Josef Rostafinski in 1873 and remains a well-defined genus of the slime molds. Hemitrichia species exhibit either plasmodiocarp or sporangium fruiting bodies, both of which are well-known and recognizable slime molds seen on multiple continents. This genus includes species such as H. serpula (known as the pretzel slime mold) and H. decipiens (known as salmon-eggs), both of which are widespread.
