Heterocyanococcus

Generic name: HETEROCYANOCOCCUS Kufferath, 1929. Ann. Cryptog. Exot. 2: 50.
Synonyms: ELEUTHERONEMA Weber van Bosse in Borzi, 1914. N. Giorn. Bot. Ital. 21: 354.
Diagnosis:
Type species: Heterocyanococcus haumanii Kufferath 1929. - Monospecific genus.
Descriptions:
Komárek (1992): Thallous; thallus in form of small, simple, three-dimensional, tetrahedral, cubic or iregular, packet-like clusters of densely and irregularly gathered cells of indefinite size, microscopic; cells sometimes arranged in short rows, without enveloping common mucilage. Cells irregular, subspherical, flattened at sides connected with neighbouring cells, with blue-green, slightly granular content. Around cells firm, thin, not gelatinizing and not stratified colourless sheaths. Heterocytes subspherical or hemispherical, developing at sides (marginally) of cell clusters. Akinetes not observed.
