Pseudocyphellaria gretae is characterised by: irregular rosettes formed of broadly rounded to sublinear lobes with entire to incised, crenulate, and often densely isidiate margins; a densely to sparsely tomentose upper surface, often with granular to coralloid tomentose isidia spreading as a thick, diffract crust; a white medulla; a green photobiont; a densely tomentose lower surface with minute, scattered white to pale-yellow pseudocyphellae; and no detectable chemistry.
