Abstract This study aimed to fully utilize Ganoderma lucidum (called lingzhi in China, reishi in Japan) residues as raw materials and a sizing agent in the papermaking industry to alleviate their environmental pollution and the shortage of papermaking resources. The refined Ganoderma lucidum residues can be used to replace 30 % of the plant pulps. Moreover, the prepared papers had better physical properties than pure plant fiber papers. After polysaccharide extracting, the tear index and folding endurance increased by 26 % and 34 %, respectively. In addition, the Ganoderma lucidum residues-based resin as a sizing agent achieved a similar effect of alkyl ketene dimer (AKD). The Cobb index reduced from 84.1 g m − 2 84.1\hspace{0.1667em}\text{g}\hspace{0.1667em}{\text{m}^{-2}} to 72.5 g m − 2 72.5\hspace{0.1667em}\text{g}\hspace{0.1667em}{\text{m}^{-2}}.
