Ulva lactuca is not listed under any importance categories.
|Phylum||Chlorophyta||Green seaweeds and stoneworts|
|Recorded Distribution in Britain and Ireland||An ubiquitous plant found on all but the most exposed rocky shores, but is probably under-recorded in Ireland.|
|Habitat information||The sea lettuce is found at all levels of the intertidal, although in more northerly latitudes and in brackish habitats it is found in the shallow sublittoral. In very sheltered conditions, plants that have become detached from the substrate can continue to grow, forming extensive floating communities. The plant tolerates brackish conditions and can be found on suitable substrata in estuaries.|
|Description||A small green alga (up to 30 cm across) with a broad, crumpled frond that is tough, translucent and membranous. It is attached to rock via a small hold-fast .|
|Additional information||Ulva is sometimes eaten as "green laver", but it is considered inferior to purple laver.|
