Gelidiella calcicola is a rare seaweed species in the Rhodophyta, described for the first time in 1988. [1] [2]
Gelidiella calcicola is a small creeping alga that forms prostrate low-growing tufts on the surface of calcareous substrata. [1] The narrow compressed axes form peg-like rhizoidal attachment organs, and the axes branch laterally to form irregular pinnate branches. [1] There are no true erect axes since all branches are in an horizontal plane. The axes which grow up at first always curve down and re-attach. [1] They grow to at least 30 millimetres (1.2 in) long and are dark reddish brown. [1] The species is very rare and may be under-recorded; it is sublittoral and not easily determined. [1]
Gelidium pusillum is common in the British Isles and is similar in structure however it branches regularly and the production of tetraspores in stichnidia is different as is the internal structure when studied microscopically. [1]
Ballygally or Ballygalley is a village and holiday resort in County Antrim, Northern Ireland which lies on the Antrim coast, approximately 3 miles north of Larne. It is also a townland of 769 acres and is situated in the civil parish of Carncastle and the historic barony of Glenarm Upper. It had a population of 821 in the 2011 census. It is located within the Mid and East Antrim Borough Council area.
Atractophora hypnoides is a rare red alga (Rhodophyta) found in the British Isles, France and some Atlantic Islands and is the only species of the genus found in the British Isles. It is attached to the rock or other algae by a small basal disc and is much branched with downgrowing filaments which enclose the main branch or axis forming a cortex. Short filaments of limited growth radiate in whorls from the axis and frequently convert into hairs. The spreading filaments grow irregularly in a diffuse manner. Microscope examination is required for identification.
Schmitzia hiscockiana is a small, rare, red seaweed or marine alga of the phylum Rhodophyta or red algae. It was discovered and named in 1985.
Polysiphonia atlantica is a small filamentous species of red marine algae Rhodophyta. The thalli form small tufts up to 3 cm long. The axes are ecorticate consisting of axial cells surrounded by four periaxial cells.
Polysiphonia ceramiaeformis, also called banded siphon weed, is a small red algae (Rhodophyta), in the genus Polysiphonia. Individuals are irregularly branched with the branches extending up to 5.5 centimetres (2.2 in) from a central node and ending in dense tufts of fibres.
Polysiphonia denudata is a small red alga, Rhodophyta, growing as tufts up to 20 cm long without a main branch axis.
Polysiphonia devoniensis is a species of marine algae. It is a small red alga in the Division Rhodophyta. It is a species new to science only described recently and first published in 1993.
