Description
Kurosaki and Hosaka report, in 2026, the rediscovery of Resupinatus merulioides at its type locality in Nikko, Tochigi Prefecture, Japan. It comes four decades after its 1987 description by Redhead and Nagasawa, with no records from that locality since. The species is odd for its wrinkled, maze-like spore surface rather than gills. The authors collected specimens at Nikko and elsewhere, compared anatomy, and sequenced DNA.
The collections matched the description, though some bodies varied in coloration, and phylogenetic analysis grouped them into one clade distinct from other genus members. Specimens filed under the same name from New Zealand formed a sister clade, distinct and probably a different species wearing the wrong label. Because the new material adds characters and DNA the holotype lacked, the authors designate one Nikko collection as an epitype, a specimen anchoring the name. It was grown and extracted using standard media such as 2 percent extract broth.
