Abstract

The previously presumed lost holotype of Diacheopsis pieninica is examined using light and scanning electron microscopy. A text description of this species from the original publication is given and supplemented with illustrations, more accurate measurements of spore diameter, and characteristics of capillitium, spores, and the peridium inner surface under SEM.
