''Trichophilus'' consists of prostrate filaments of cells. Filaments are one or multiple cells wide, dividing irregularly to form short branches, and are crowded and parenchyma-like (pseudoparenchymatous). Cells have thick walls and each contains a parietal chloroplast with an obscured pyrenoid. ''Trichophilus'' reproduces via zoospores of two sizes, each with four flagella.<ref name=John2014>{{cite book |editor-first1=John D.|editor-last1=Wehr|editor-first2=Robert G.|editor-last2=Sheath|editor-first3=J.
