Three Chlorophyceae From Alabama Soil

Abstract

Deason, Temd R. (U. Texas, Austin.) Three Chlorophyceae from Alabama soil. Amer. Jour. Bot. 46(8): 572–578. Illus. 1959.— Three new algae from Alabama soil are described as follows: Spongiococcum gen. nov., with 2 species, S. tetrasporum sp. nov. and S. alabamense sp. nov. The distinguishing attributes of the genus Spongiococcum are: (1) possession of a sponge‐like plastid; (2) presence of pyrenoids; and (3) Chlamydomonas‐type zoospores. The description of the genus Chlorosarcina Gerneck is emended with respect to zoospore type, and Chlorosarcina stigmatica sp. nov. is described. Cultures of these organisms have been deposited in the Culture Collection of Algae, Department of Botany, Indiana University, Bloomington, Indiana, and herbarium specimens have been sent to the Chicago Natural History Museum, Chicago, Illinois.

10. Snow algae of the Windmill Islands region, Antarctica

“…There are comparable species in the Chlorosarcinopsis but the cells in this genus possess pyrenoids. The plant has tentatively been placed in the genus Chlorosarcina because it has various characteristics in common with those of Chlorosarcina stigmutica Deason (1959) but it must be borne in mind that there is considerable controversy surrounding C. stigmutica (Sluiman & Blommers, 1990) and the genus Chlorosarcina itself. Confirmation that the alga belongs in the Chlorophyceae would require a study of the ultrastructure, especially of the flagellar basal apparatus of the zoospores.…”

The Biological Soil Crusts of the San Nicolas Island: Enigmatic Algae from a Geographically Isolated Ecosystem

“…Originally, the genus Chlorosarcina was described as containing 3 species (C. brevispinosa, C. longispinosa, and C. stigmatica), and it was placed in the class Chlorophyceae with C. stigmatica as the type species (Deason 1959). Subsequently, Deason and Floyd (1987) separated C. stigmatica from C. longispinosa and C. brevispinosa based on ultrastructural characteristics and placed C. longispinosa and C. brevispinosa in the Pleurastrophyceae (now Trebouxiophyceae) based on several characteristics, including counterclockwise orientation of the flagellar apparatus components.…”

A study of newly recorded genera and species of aerial algae in the order Chlorococcales (Chlorophyta) from the Hongcheon-river, Korea

“…This species has been found among aerial algae (Deason 1959). In this study, this species was found in a wide range of habitats where the light intensity and humidity ranged from 3,915-48,000 lux and 26-65%, respectively (Table 2).…”

“…This genus was named by Deason in 1959, and newly recorded in this study in Korea. Deason (1959) isolated the genus Spongiococcum from a soil sample in Alabama, USA, and described it as a sponge-like plastid, with a pyrenoid and Chlamydomonas-type zoospore.…”

“…Deason (1959) isolated the genus Spongiococcum from a soil sample in Alabama, USA, and described it as a sponge-like plastid, with a pyrenoid and Chlamydomonas-type zoospore. In Guiry and The cells are spherical, 15-30 µm in diameter.…”
