Parmotrema paramoreliense W.L. Culb. & C.F. Culb., 1981
Parmotrema paramoreliense can be recognized by the laciniate, sorediate thallus, effigurate maculae, black and widely naked undersurface, long cilia (up to 5 mm) and variedly branched, sometimes very thick rhizines (up to 0.3 mm).
This is a strange species inside the group of Parmotrema with salazinic acid, being probably more related to the genus Everniastrum Hale ex Sipman. Although the effigurate maculae and dimorphic rhizines could place P. paramoreliense together with the species of the former genus Rimeliella, the remaining features have no parallel in this group. Future investigations in the ascospores and conidia, not known up to now, can help to clarify the positioning of this taxon.
Although Culberson & Culberson (1981) asserted that pycnidia are relatively common in this species, they are rare in the holotype, and no conidia could be seen.
