Morphology of Vaucheria incurva from new locality: 1–3—general view of proliferating fruiting branches, note multiple proliferations on Figs. 2, 3; 4—detail of fruiting branch with antheridium and oogonium, which are not separated clearly from gametangial pedicels; antheridium is in focus; 5—antheridial pedicel bearing empty antheridium; 6, 7—oogonial pedicels bearing oospores weakly fixed with remnants of oogonial walls; 8–10—mature oospores liberated from oogonial walls.
