Abstract:
The author describes a new species of the blue-green algae, Lyngbya subclavata Starmach n. sp.; see the Latin diagnosis, p. 147. Lyngbya subclavata occurs on wet rocks within the range of water splash. It has been heretofore found on granite crocks of the Wodospady Mickiewicza (Mickiewicz Waterfalls) in the Roztoka Valley in the Tatras, The species described is characterized above all by the broadened ends of the trichomes, the size and the granulation on the walls of the crosscells. On account of the breadth of its trichomes the species is close to Lyngbya Digueti Gom., L. amplivaginata V. Goor., and L. halophila Hansg. Other characters instead are pronouncedly different. Plectonema Jaagii Geitler (Pl. capitata Jaag) found in similar ecological conditions, i. e. in the range of water splash at a waterfall, is characterized by broadened ends of the trichomes. Much like Lyngbya subclavata, this species has also upright ends of filaments rising perpendicularly to the substratum; on these a characteristic sphere of growth is formed, which, however, ends with unnaturally broadened, vacuolized and degenerating apical cells. Evidentiary material is in the possession of the Algologicai Laboratory of the Botanicad Institute, Polish Academy of Sciences in Kraków.
