Bacidia rosellizans , a new lichen species from the taiga belt
Abstract Bacidia rosellizans S. Ekman is described as new to science. Morphologically, the new species is similar to the type species of the genus, B. rosella (Pers.) De Not., particularly in the pale pink and pigment-deficient apothecia and in having the proper exciple and upper part of the hymeniu...
