ツチダンゴ属 Elaphomyces は 1820 年にT. Nees により設立された、外生菌根性の地下生菌からなる子嚢菌の属である。本属のタイプ種であるツチダンゴE. granulatus およびアミメツチダンゴ E. muricatus は、1829 年に Elias Magnus Fries によって認可された、本属で最も広く知られている種である。これら2 種は本属が設立される遥か以前から知られており、様々な学名が与えられていた。本稿では E. granulatus および E. muricatus を主軸に、ツチダンゴ属の主要な分類学史を紹介し、これら2種を取り巻く日本のツチダンゴ属研究史についても解説する。


The genus Elaphomyces, described by T. Nees in 1820, is comprised of ectomycorrhizal, truffle-like ascomycetes. The generic type species, E. granulatus, as well as E. muricatus, were described by Elias Magnus Fries in 1829, and they are regarded as sanctioned names. These species, however, had been known long before the genus was established and various scientific names were given by different authors. This review summarizes the taxonomic history of the genus Elaphomyces with emphasis on E. granulatus and E. muricatus. We also briefly review the taxonomic history of Elaphomyces in Japan including the two major species mentioned above.
