Peña,V. & Bárbara, I. (2010). New records of crustose seaweeds associated with subtidal maërl beds and gravel bottoms in Galicia (NW Spain). Botanica marina 53: 41-62.

We studied crustose seaweeds associated with subtidal mae¨rl beds and gravel bottoms in the Galician r´as (NW Iberian Peninsula). Each species is described as well as its habitat and occurrence in mae¨rl beds and gravel bottoms. We confirmed the great crustose species richness associated with European Atlantic mae¨rl beds. We report a new species for the Atlantic Ocean (Contarinia peyssonneliaeformis) and six new records for the Iberian Peninsula (Atractophora hypnoides stage Rhododiscus pulcherrimus, Peyssonnelia immersa, Scytosiphon lomentaria stage Microspongium gelatinosum, Petroderma maculiforme, Pseudolithoderma roscoffense and Phycocelis foecunda). Peyssonnelia armorica is a new record for the Atlantic Iberian Peninsula and Peyssonnelia harveyana is a new record for the Galician coast. We provide for the first time observations on spermatangial structures in Cruoria cruoriaeformis occurring on the Atlantic Iberian Peninsula. The Galician crustose algal flora of subtidal maerl beds and gravel bottoms is increased up to 23 species (15 Rhodophyta and 8 Ochrophyta). Peyssonnelia rubra is excluded from the Galician flora.
