KEYWORDS
ABSTRACT
We describe Diploschistes stereocaulorum as a new species of lichenized fungi
growing on phyllocladia and stalks of Stereocaulon in the Pacific Northwest of North
America. The larger ascospores of this species, the absence of a noticeable thallus, and the
ITS barcode locus distinguish it from D. muscorum, which has been reported as growing
on Stereocaulon, but has smaller ascospores and a distinct thallus. In phylogenetic reconstruction,
the new species is sister to D. diacapsis, albeit without support.
