This paper presents information on the ecology and distribution of four species of Portuguese bryophyte flora. Dichodontium pellucidum (Hedw.) Schimp. and Blindia acuta (Hedw.) Bruch & Schimp. are recorded for the first time in Portugal. Jungermannia obovata Nees, is confirmed in two recently found localities, and Climacium dendroides (Hedw.) F. Weber & D. Mohr, a moss whose last records in the same area date 140 years, and which is currently considered to be extinct in Portugal, is confirmed.
