An investigation of the severe destruction of wood ear mushroom (Auricularia auricula-judae), which were commercially cultivated in a plastic house in Hwabuk-myeon, Jeju-si, South Korea from April to August 2021, revealed a tenebrionid beetle subsequently identified as Platydema takeii Nakane, 1956 (Coleoptera: Tenebrionidae: Diaperinae). To the best of our knowledge, this is the first report of a tenebrionid species infesting commercially cultivated mushrooms in South Korea. The damage symptoms and diagnosable characteristics of adults and larvae of P. takeii are provided in this study.

We conducted field and laboratory observations of the life histories and fungal hosts of the darkling beetle, Platydema nigroaeneum Motschulsky. P. nigroaeneum, a fungivorous tenebrionid beetle, was a widespread inhabitant of fungi on deciduous trees (Quercus, Salix, Alnus and Carpinus etc.) in Korea. Development from egg to adulthood took $4\sim11$ months in nature and about 66 days in the laboratory at $25.5{\sim}26.1^{\circ}C$ and $63.5\sim64.5%$ relative humidity. Both larvae and adults overwintered in their host fungi or beneath the bark of the host tree near the host fungi. Sporophores of Coriolus $Qu{\acute{e}}let$, Bjerkandera Karst., Daedaleopsis Schroet. and Merulius were common feeding and breeding sites in Korea.
