The new species, Gyalectidium floridense Safranek & Lücking, found on leaves of Citrus in Florida, is described and illustrated. Gyalectidium floridense belongs in the G. areolatum group (Gyalectidium sect. Areolectidium ser. Areolate), which is chiefly characterized by a crystalline thallus where the calcium oxalate crystals aggregate to form large areoles on the thallus patches. Within this group, the new species is distinguished by rather narrow, folded, and horn-shaped hyphophores produced on the thallus surface.
