KICKXELLA Coemans, 1862 (Bull. Soc. Royale Bot. Belgique 1:155); 1 sp. (Bainier, 1906; Benjamin, 1958; Coemans, 1862; Linder, 1943; Young, 1968a, 1968b, 1974).
= Coronella nivea Crouan, 1867 (Florule de Finistère, p. 12: Tab. Suppl.; Torrey, 1921).
= Coemansiella alabastrina Saccardo, Syll. Fung. II: 815) (Beer, 1902).

Hyphae septate, sporangiophores simple or branched, with an apical vesicle bearing three-celled sporocladia verticellately. Pseudophialides borne on the upper surface of the inner two sporocladial cells. Sporangiospores fusiform. Zygospores more or less globose, borne on undifferentiated hyphae.

Type species: K. alabastrina

Species of Kickxella:
K. alabastrina Coemans, 1862 (Bull. Soc. Royale Bot. Belgique 1:153).

Sporulation of K. alabastrina occurs optimally on CMPY agar at 20 C. Zygospores are produced at 6-7 C. The mode of zygospore production is similar to that of Coemansia (Benjamin, 1958). Scanning EM photographs of K. alabastrina can be found in O’Donnell (1979).
