Prasiola stipitata is a small green alga.
This alga grows to no more than 1 centimeter long, is fan shaped with a distinct stipe. The vegetative frond is monostromatic. The cells in the blade are arranged in packets of 4 or more. In colour the fronds are dark green. [1] [2]
P. stipitata thrives in high-nutrient habitats and is therefore often found in the spray water zone of shores frequented by sea birds. [3] [4]
Rather erratic in its distribution. [5] Recorded mostly from cold-temperate regions on both hemispheres, e.g. Iceland, the Faroes, Atlantic coasts of North America and Europe, including Great Britain and Ireland, as well as from Australia and New Zealand. [2] [6]
Sexual and asexual plants have been recorded. [2]
Prasiola is a genus of fresh water and marine green algae. Each individual plant is small but they usually grow side by side to form a green turf on rock surfaces. The genus has a cosmopolitan distribution.
Palmaria palmata, also called dulse, dillisk or dilsk, red dulse, sea lettuce flakes, or creathnach, is a red alga (Rhodophyta) previously referred to as Rhodymenia palmata. It grows on the northern coasts of the Atlantic and Pacific Oceans. It is a well-known snack food. In Iceland, where it is known as söl, it has been an important source of dietary fiber throughout the centuries.
Ascophyllum nodosum is a large, common cold water seaweed or brown alga (Phaeophyceae) in the family Fucaceae. Its common names include knotted wrack, egg wrack, feamainn bhuí, rockweed, knotted kelp and Norwegian kelp. It grows only in the northern Atlantic Ocean, along the north-western coast of Europe including east Greenland and the north-eastern coast of North America. Its range further south of these latitudes is limited by warmer ocean waters. It dominates the intertidal zone. Ascophyllum nodosum has been used numerous times in scientific research and has even been found to benefit humans through consumption.
Pelvetia canaliculata, the channelled wrack, is a very common brown alga (Phaeophyceae) found on the rocks of the upper shores of Europe. It is the only species remaining in the monotypic genus Pelvetia. In 1999, the other members of this genus were reclassified as Silvetia due to differences of oogonium structure and of nucleic acid sequences of the rDNA.
Ulva intestinalis is a green alga in the family Ulvaceae, known by the common names sea lettuce, green bait weed, gutweed, and grass kelp. Until they were reclassified by genetic work completed in the early 2000s, the tubular members of the sea lettuce genus Ulva were placed in the genus Enteromorpha.
Osmundea pinnatifida is a species of red alga known by the common name pepper dulse.
Codium fragile, known commonly as green sea fingers, dead man's fingers, felty fingers, forked felt-alga, stag seaweed, sponge seaweed, green sponge, green fleece, sea staghorn, and oyster thief, is a species of seaweed in the family Codiaceae. It originates in the Pacific Ocean near Japan and has become an invasive species on the coasts of the Northern Atlantic Ocean.
Chorda filum, commonly known as dead man's rope or sea lace among other names, is a species of brown algae in the genus Chorda. It is widespread in the temperate waters of the northern hemisphere. The species has numerous other common names related to its physical appearance. These include mermaid's tresses, cat's gut or sea-catgut, bootlace weed, sea-twine, and mermaid's fishing line.
Dumontia contorta is a relatively small epiphytic algae of the sea-shore.
Choreocolax polysiphoniae is a minute marine parasitic alga in the division Rhodophyta.
Ceramium shuttleworthianum is a small marine red alga.
Membranoptera alata is a small red alga in the Rhodophyta.
Phyllophora pseudoceranoides, the stalked leaf bearer, is a small marine red alga.
Odonthalia dentata is a medium-sized marine red alga.
Prasiola crispa is a small terrestrial green alga. It has been recorded world-wide mostly from cold-temperate to polar regions.
Prasiola furfuracea is a small green alga that grows terrestrially.
Codium bursa is a green marine algae of medium size.
Gymnogongrus griffithsiae is a small uncommon seaweed.
Cladostephus hirsutus is a marine brown alga.
Prasiola calophylla is a species of algae.
