Type study of Japanese Dacrymycetes described by Yosio Kobayasi: Redescriptions of five species and a new name proposal

The Japanese mycologist, Yosio Kobayasi, described 16 species of Japanese Dacrymycetes. Almost all of the type specimens were thought to have been destroyed during World War II. In this study, Kobayasi's specimens were surveyed, and holotypes of six species, Dacrymyces adpressus Kobayasi, D. applanatus, D. pezizoides, D. puniceus, D. subalpinus, and Dacryopinax imazekiana, were found and recognized as distinct species. Dacrymyces adpressus Kobayasi, a later homonym of D. adpressus Grognot, was redescribed with a new name, D. kobayasii. The mycoflora of Japanese Dacrymycetes has been updated to 44 species in nine genera.
