somewhat dark; spores colorless, tapering to varying degrees, 1-4 celled, ca. 12-13/xm x 2-3/im. Small thalli of
another Byssoloma species are also present on some specimens however the apothecial disks are darker
(purple-brown), and the thallus is UV-. Brodo et al. (2001) included B. pubescens Vezda ex Harris as a
