P. glaucomaria P. protoparmeliae P. zwackhii Phacographa is a genus of lichenicolous (lichen-dwelling) fungi in the family Roccellaceae.

[2] The genus was circumscribed in 2009 by the Austrian lichenologist Josef Hafellner, who assigned Phacographa glaucomaria as the type species.

One hymenium is made per ascoma, and they are exposed early in their development, resulting in bits of plectenchyma (fungal tissue) that crumbles off.

[3] Phacographa species make hyaline (translucent) ascospores with three septa (internal partitions) and rounded ends.

A thin sheath (the perispore) initially covering the spore eventually results in a verruculose (slightly pimply) surface texture in maturity.
