CORRECTION OF ALGAL BINOMIAL

In making the combination Pterosiphoma clevelandii, I erroneously believed that the
variety clevelandii Farlow (1877) was validly published. This is not the case* hence
necessitating a new name and a valid description. As previously stated* No. 183 of the
Farlow, Anderson and Eaton exsiccatae (in the Farlow Herbarium, Harvard University)
is the lectotype, This specimen is photographed (Hollenberg 1970, fig, zo) and a
portion of it illustrated (Hollenberg 1970, fig. 1j) in detail, showing recurved ultimate
branehleis, diagnostic for the species.
