Endococcus perpusillus
General description:
The name has historically been used for a species aggregate associated with a range of different lichens. Those on species of Rhizocarpon may now be referable to E. exerrens or E. fusiger, those on Apicilia to E. verrucosus and a record on Protoblastenia could be E. protoblasteniae. The type of E. perpusillus is on Schaereria tenebrosa, and apparently has not yet been reported from GBI. Phylogeny and the degree of host specieficity need more research within this genus.
