Краткое описание

The paper presents a first record of xantophycean alga Vaucheria velutina in Ukraine. The species is characteristic of the sea coasts of most European countries, known from the marine coasts of North Africa, America, Asia, Australia, and New Zealand but it has never been cited from the Black Sea coast. The dimensional characteristics of the thalli and reproductive organs of Tiligul specimens mainly correspond to the accepted description of V. velutina. Filaments are straight, unbranched, bisexual, and 70-120 μm wide. Antheridia are ovate-oblong with ascending apex, 100-150 μm × 60-80 μm. Oognia obovate to almost rounded with protruding papilla, sessile, 200-230 μm × 180-200 μm. Oospores 190-210 μm × 170-190 μm. It was revealed in the benthos of Tiligul Estuary at a depth of 0.5 m in the community formed by representatives of Chlorophyta and Rhodophyta. Alga formed small olive green clusters on the bottom. Environmental parameters of the microhabitat: water of chloride-sodium-sulphate-magnesium type with a salinity of 32.29‰, pH 8.12, temperature 19 °C. Identified specimens also have some similarities with V. dichotoma but differ from it in a number of morphological and ecological features.
