Spore morphology in the Nidulariaceae (fungi) as revealed by the scanning electron microscope

Basidiospores of species representing each of the five genera in the fungus family Nidulariaceae when examined and photographed using the scanning electron microscope appear to have smooth surfaces. Among the species chosen for study, those representing Mycocalia, Nidularia, and Nidula all possess spores which bear a hilum, which has apparently been overlooked in examinations based on light microscopy.
