Description
Fasciculochloris has young vegetative cells which are oblang or ovoid but gradually become spherical upon aging. They average 7.5 µm in diameter, rarely exceeding 14 µm before division. Cell division may result in production of zoospores, or, if vegetative, in formation of packets of mostly 4 but up to 32 cells in two or three planes. Packets average 15 X 18 µm, but may attain a maximum size of 26 X 28µm. In young cells the cup-like chromatophore and pyrenoid are apparent. More than one pyrenoid may be present in each cell, especially just before cell division. In liquid and agar culture in the stationary phase, walls becme mucilaginous and cells of the packets separate. All cells were uninucleate. Young cells appear granular because of the accumulation of numerous starch grains, but in old cells oil appears to be the main storage product. In each sporangium, 4 to 16 zoospores may be produced. Zoosporangia may reach a maximum diameter of 20 µm. Zoospores have two flagella of unequal length, a parietal chromatophore containing a pyrenoid, two contractile vacuoles, a median posterior stigma, and a thin cell wall. Zoospores have an average size of 4 X 7 µm and do not round up on quiescence. Sexual reproduction was not observed. Smooth and glossy colonies are produced on agar. A second strain of Fasciculochloris boldii is in culture; it produces rough colonies on agar, shows less gelatinization of the wall, and forms few packets in liquid culture. UTEX1451
