Abstract
Notulae to the Italian flora of algae, bryophytes, fungi and lichens: 1
Highlights
Dicranella rufescens was found on arenaceous and loam soils with a highly nitrified substrate caused by numerous seabird colonies in the northern sector of the island sheltered from the northwesterly winds and from marine aereosol, in temporarily soaked meadows
The island consists of Paleozoic lithologies with a porphyry granite crossed by a dyke system with NNW-SSE orientation
The vascular vegetation is a typical halo-nitrophytic ephemeral community composed of Crassula tillaea Lest.-Garl. and Sagina apetala Ard. (Biondi et al 1993)
Summary
Dicranella rufescens was found on arenaceous and loam soils with a highly nitrified substrate caused by numerous seabird colonies in the northern sector of the island sheltered from the northwesterly winds and from marine aereosol, in temporarily soaked meadows. Abstract In this contribution, new data concerning lichens and bryophytes of the Italian flora are presented. Exclusions, and confirmations to the Italian administrative regions for taxa in the lichen genera Athallia, Ramonia, Thelotrema, Pertusaria, Bryoplaca and in the bryophyte genera Dicranella, Bryum, and Scorpiurium. + SAR: Isola di Serpentara, Villasimius (Cagliari), on soil in the field with NNW exposure (UTM WGS84: 32S 552402.4332704), 30 m, 30 January 1998, A.
