| Description: |
Chondria coerulescens has bluish or yellowish fronds with blue iridescence. The fronds are flexible and cartilaginous in texture, turning black when dry. Young axes show a striking turquoise iridescence when alive. The thalli consist of cylindrical erect axes or trailing tufts, and is 3-8 cm high when erect. The distinct main axis is 0.4-0.5 mm in diameter, branching sparsely at irregular intervals in a spiral pattern to 1-3 orders of branching. Branches are linear, often long and curve downwards gradually tapering to a slender point, and reattach by secondary holdfast. The morphology shows relatively little variation except that some thalli consist only of inconspicuous isolated erect axes whereas others form dense tufts. |
