Abstract

We surveyed some major fungal herbaria in Japan to find collections of "extinct" mushroom species. The presence of voucher collections was confirmed for a total of 21 out of 26 "extinct" mushroom species listed in a Red Data Book of Japan. We then assessed the type status and quality of these specimens based on collection data on collection labels and physical appearance of fruit bodies. The majority of voucher collections of "extinct" species were demonstrated to be the type (holotype, isotype or syntype) with various degrees of quality. Some were heavily contaminated by mold or highly fragmented into small pieces. In future, attempts will be made to obtain high quality DNA sequences from these “extinct” species to clarify their biological entity.
