dc.description.abstractIntroduction. This article provides a detailed analysis of the spore morphology and ultrastructure of Alophosia azorica (Renauld & Cardot) Cardot, a Macaronesian endemic moss of the family Polytrichaceae, reviews its morphological characters, and clarifies its life strategy. Methods. The specimens used in this study came mainly from the bryophyte sections of the herbaria of the University of the Azores (AZU) and the University of Lisbon (LISU), with fresh samples also collected in the field. Observations were made and measurements taken of the stem, leaves, rhizoids, capsule and setae, for comparison with published reports. Sporophytes from five specimens of Alophosia azorica were separated to study spore morphology using light and scanning electron microscopy. Key results and conclusions. The specimens investigated in this study exhibited the typical characteristics assigned to the species in previous studies. The examined spores are isomorphic monads, heteropolar with a subcircular amb, spheroidal in polar view, convex-plane in equatorial view, with psilate exospore and presence of a perispore with microechinate ornamentation, and are very small. Alophosia azorica is considered a colonist sensu stricto due to its small, abundant spores, the production of sporophytes across two seasons, and the presence of asexual propagules, indicating a moderate reproductive effort.eng
