Phacographa is a genus of lichenicolous (lichen-dwelling) fungi in the family Roccellaceae.[1] It has three species.[2]
The genus was circumscribed in 2009 by the Austrian lichenologist Josef Hafellner, who assigned Phacographa glaucomaria as the type species.[3] This species was originally described by William Nylander in 1852 as a member of the genus Lecidea.[4] In addition to the type, another species was transferred from the genus Opegrapha, and a third species was described as new. The genus name, which combines the Greek phakos 'lentil' with grapho 'write', alludes to its relationship with the genera Phacothecium and Opegrapha.[3]
