First
described in 1821 by Swedish mycologist
Elias Magnus Fries, it has since acquired an extensive
synonymy of alternate scientific names. Until 2014, it was the sole member of the
Climacocystis, a genus circumscribed by Czech mycologists
František Kotlaba and
Zdeněk Pouzar in 1958, when the newly described Chinese species
Climacocystis montana was added to the genus. ==Description ==
