In the present study 21 Pottiaceae species are recorded from the Omayed Protected Area (OPA). Only one genus; Acaulon Müller Hal. and two species; Acaulon triquetrum (Spruce) Müll. Hal. and Pseudocrossidium obtusulum (Lindb.) H.A. Crum & L.E. Anderson are new records on bryoflora of Egypt. The last species is also a new record to North Africa. Two species; Aloina rigida (Hedw.) Limpr. and Gymnostomum calcareum Nees & Hornsch. are new records to OPA. Thus, number of moss taxa and moss genera recorded from Egypt are increased to 186 and 59 respectively, while no. of Pottiaceae taxa is increased to 89. Descriptions and illustrations of these new records together with geographic distribution in Egypt and occurrence in the Mediterranean countries of all recorded taxa are given.
