[Objective] This paper reports the new recorded species of Anthocerotophyta to Xizang, which enrich the study of bryophytes flora in Xizang. [Methods] Through the identification and analysis of bryophytes collected from Sygera Mountains in Xizang were carried out in order to provide references for the study of bryophyte diversity in Xizang and by means of classical taxonomical methods and ultrastructural observation. [Results] Anthoceros punctatus L. and Phaeoceros laevis (L.) Prosk were found to be new recorded species in Xizang. [Conclusion] Their morphological characteristics were described. Pictures of micromorphology and ultrastructure of spores were provided, and their habitat and distribution were analyzed. The discovery of these two species enriched the flora list of bryophytes in Xizang Autonomous Region and provided new information for the study of hornwort.
