Optical sec- tion of sporangium x 300. After Brefeld. Pathogenic properties. Said to be pathogenic for various birds but Pierre Savoure, after some extensive experiments thinks that it plays no part in disease. It was not pathogenic for rabbits and guinea pigs. Bollinger states that it occurs in the respiratory tract of birds where it produces mucormy- t:osis. It has been observed in cutaneous lesions in cavalry horses in France, although culture did not yield this fungus but yielded a trichophyte instead. Mucor ramosns, Lindt. Mycelium spreading in the substratum, small, branched, at first white then becoming grayish-white; sporangia black, spherical with marginal spines 60-80 ij. in diameter; columella ovate, light brown, SO f- wide; spores somewhat spheri- cal, M in diameter, colorless. Distribution and Habitat. Found in Europe, not abundant. Pathogenic properties. Pathogenic for birds. Grows only at a temperature of blood, minimum 20-25° C, maximum 50-58°, optimum 45°. Mucor ramosus, Lindt Mycelium branching, abundant in the substratum and superficial conid- iophores 5-lS li wide; sporangia blackish, membrane but slightly colored, 70 a* in diameter; columella rounded at the end or blunt; spores colorless, with delicate membrane, smooth, 3 to 4 m x 5-6 i^. This resembles M. corymbifer â except in the character of the spores. Pathogenic properties. Pathogenic for guinea pigs, death occurring in 30 to â¢36 Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustr
