Abstract:
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.
