| Name | Notes |
|---|---|
| green branched weeds | Cladophora aegagropila (cladophoraceae) |
| Key criteria: | A small freshwater species found in maritime situations and in marine caves. Under-recorded and its seeming absence from Ireland is probably due to this. ~ |
| no common name | Cladophora albida (cladophoraceae) |
| Key criteria: | Large (to 15-50 cm) regularly branched filamentous alga that occupies a variety of habitats in the lower intertidal and shallow subtidal zones growing mostly epilithically particularly in pools. Members of this genus are extremely difficult to separate morphologically and this species is probably under- recorded here. epilithic lower intertidal intertidal shallow subtidal subtidal pool |
| no common name | Cladophora coelothrix (cladophoraceae) |
| Key criteria: | Forming large cushion-like tufts in the lower intertidal and in sheltered subtidal habitats probably very rare but poorly known. lower intertidal intertidal subtidal sheltered |
| no common name | Cladophora dalmatica (cladophoraceae) |
| Key criteria: | Large (to 50 cm) regularly branched filamentous alga found in the intertidal zone particularly in pools and free- floating in lagoons; penetrating into brackish water. Members of this genus are extremely difficult to separate morphologically and this species may be under-recorded here. intertidal pool brackish |
| no common name | Cladophora flexuosa (cladophoraceae) |
| Key criteria: | Large (to 25 cm) much-branched filamentous alga found in the intertidal zone particularly in pools. Members of this genus are extremely difficult to separate morphologically and this species may be under-recorded here. intertidal pool |
| no common name | Cladophora hutchinsiae (cladophoraceae) |
| Key criteria: | Large (to 25 cm) much-branched filamentous alga found in the intertidal and shallow subtidal zones. Members of this genus are extremely difficult to separate morphologically. This species is poorly known and may be under-recorded here. intertidal shallow subtidal subtidal |
| no common name | Cladophora laetevirens (cladophoraceae) |
| Key criteria: | Smaller (to 10 cm) regularly branched filamentous alga found in the intertidal and shallow subtidal zones particularly in pools. Members of this genus are extremely difficult to separate morphologically. The records suggests that the species may be more common in the south-west but it is probably under- recorded here. intertidal shallow subtidal subtidal pool |
| no common name | Cladophora liniformis (cladophoraceae) |
| Key criteria: | Large (to 35 cm) much-branched filamentous alga found in the intertidal and shallow subtidal zones usually free- floating in sheltered environments. Members of this genus are extremely difficult to separate morphologically. This species is poorly known and may be under-recorded here. intertidal shallow subtidal subtidal sheltered |
| pellucid green branched weed | Cladophora pellucida (cladophoraceae) |
| Key criteria: | Large (to 25 cm) much-branched filamentous alga found in the lower intertidal and shallow subtidal zones of wave-exposed shores. This species is one of the few readily recognizable members of the genus as reflected in the large number of records. lower intertidal intertidal shallow subtidal subtidal exposed |
| no common name | Cladophora prolifera (cladophoraceae) |
| Key criteria: | Large (to 25 cm) much-branched filamentous alga that is believed to be very rare in the area but requires further investigation as members of this genus are extremely difficult to separate morphologically. ~ |
| no common name | Cladophora pygmaea (cladophoraceae) |
| Key criteria: | Tiny (1-3 mm) much-branched filamentous alga found on mobile substrata in subtidal zone of wave-exposed shores. This species is one of the few readily recognizable members of the genus as reflected in the relatively large number of records given its tiny size. subtidal exposed |
| common green branched weeds | Cladophora rupestris (cladophoraceae) |
| Key criteria: | Large (to 25 cm) much-branched filamentous alga found in the lower intertidal and very shallow subtidal zones in a wide variety of habitats. This species is one of the few readily recognizable members of the genus and is very widespread as reflected in the large number of records. lower intertidal intertidal shallow subtidal subtidal |
| no common name | Cladophora sericea (cladophoraceae) |
| Key criteria: | Large (to 25 cm) much-branched filamentous alga that is common intertidally both on exposed surfaces and in pools. Although members of this genus are extremely difficult to separate morphologically this species is believed to be common and widespread as shown here. intertidal exposed pool |
| no common name | Cladophora vagabunda (cladophoraceae) |
| Key criteria: | Large (to 50 cm) much-branched filamentous alga that forms free-floating masses in sheltered environments. Members of this genus are extremely difficult to separate morphologically. This species is poorly known and believed to be rare although it may be under-recorded here. sheltered |
