| 英文摘要 |
Geminella is a genus in the Family Ulothrichaceae. Although asexual reproduction by means of zoospores is known for most genera in the family, but zoospores are not definitely known for this genus. Samples were collected in a stagnant water from an old limestone quarry on the way to Martinsviel six miles east from Bloomington, Indiana. In this collection there was a number of Chlorophyceae mixed with Oscillatoria Bornetii Zukal, among which there were filaments identified as Geminella interrupta (Turp.) Lagerheim (1883). Single cells of this species were isolated with fine glass pipettes and placed individually in tubes of soil-water medium containing powdered calcium carbonate (Pringshein, 1950). |
