General information

 Remarks :Cryptococcus humicola
Characteristics given by other authors
Cell components include glucose, mannose, galactose, glucosamine, glucuronic acid and xylose (Gorin & Spencer 1970; Golubev & Blagodatskaya 1978; von Arx & Weijman 1979).
Coenzyme Q9 Yamada & Kondô 1972.
Mol % of G + C of nuclear DNA: 56.5, 58.8, 59.6, 60.4, 61.5, 62.9, 63.2 (Nakase & Komagata 1971f; de Hoog 1980).
Chromosome bands:
Where found
Soil in Chile, rotten toadstool in France, surface of toadstools Nematoloma lateritium and Anamita muscaria, water of stream contaminated by effluent of papermill in Czechoslovakia, skin in Germany, water in Antarctica, culture of Sachsia suaveolens Lindner CBS 320.31, radioactive solution at pH 2, sputum, soil and droppings of goose in the Netherlands, mushrooms.
Other information
Some strains grow on propan-1-ol or butan-1-ol as sole source of carbon. Some strains are pectolytic (Barnett et al. 2000). Cell wall has many layers (van der Walt & Hopsu-Havu 1976; Kreger-van Rij & Veenhuis 1971a).
