Overview

Comprehensive Description

Description

 Blidingia minima consists of fine, branched or unbranched, hollow green tubes, up to 5 cm long. Groups of tubes arise from the raised centre of a small flattened disc-shaped holdfast that is attached to the rock. Plants reproduce throughout the year, reproductive spores arising from the upper layers of the tubes.Blidingia minima can be confused with Ulva spp., but can be identified by its smaller, more delicate and sometimes branching tubes, the central disc attachment, its microscopic morphology and reproductive processes.

 Found on hard surfaces, including stones, rocks and boulders on the upper shore and in harbours and estuaries. Occasionally found free-floating in sheltered water. Blidingia minima is found in a range of salinities from almost freshwater to sea water and on exposed and sheltered shores. It may occur mixed with other species.

Blidingia minima

Blidingia minima is a species of seaweed in the Ulvaceae family. It was described by Johann Kylin in 1947.[2]

Description[edit]

The species is 1–10 centimetres (0.39–3.9 in) long by 1–2 millimetres (0.039–0.079 in) wide and is light green in colour.[3] It fronds are tubular with it cell arrangement being irregular and 10 micrometres (0.00039 in) in diameter. Stellate chloroplasts also exist. The tubes rise in groups from the center.[4] It thalli grow as clusters which carry cylindrical and hollow tubes which arise from discoidal cushion.[5] The tubes are 1–20 millimetres (0.039–0.79 in) long and 2 millimetres (0.079 in) wide. Thallus cells are 7 micrometres (0.00028 in) wide and are angular.[6]

Distribution[edit]

The species is found throughout eastern part of Asia in such countries as China, Japan, Korea and eastern part of Russia.[5] It is also found in Azores, Canada, Norway, South Africa, United States, and various gulfs, seas and oceans, such as Gulf of Maine and Gulf of Mexico and in Atlantic and Pacific Oceans and Wadden Sea.[2] Besides this places it have a type locality which is Helgoland, Germany[7] and is also common in Ireland and Great Britain.[8] It was recorded in Queensland, Australia as well.[9]

English distribution[edit]

In England, the species was recorded from East Sussex.[10]

Habitat[edit]

It is found growing on cobble, boulders, bedrocks, barnacles, driftwood and even on different algae species throughout the semi-protected and protected areas.[5]

Ecology[edit]

Blidingia minima is considered to be a food for periwinkles.[11]
