Chén Rényù 陳仁玉
Mid-Southern-Sòng pǔlù author, self-styled Shānrén 山人 (“Mountain Man”). Native of Xiānjū 仙居 in Tāizhōu 台州 (modern Zhèjiāng) — identified from the geographical references in his self-preface to Jūnpǔ 菌譜 (“Xiānjū lies between the great Tāikuò ranges, entering the immortal-spirit’s palace, where strange mushrooms grow”). His official career, family background, and exact lifedates are not documented in other sources; CBDB has no entry.
His one surviving work, the Jūnpǔ 菌譜 (KR3i0042) — the world’s first systematic mushroom-monograph — is dated by self-preface to Chúnyòu yǐsì (1245). It catalogs eleven edible mushroom species from his native Tāizhōu region, with a concluding section on antidotes to mushroom-poisoning. Composition during the high Lǐzōng period suggests Chén was active c. 1230s–1250s.
