Rhizomucor mieheiThis species has been reported as a rare cause of bovine mastitis (Scholer et al. 1983) and is similar in most respects to R. pusillus. However, all strains are homothallic forming numerous zygospores, which are reddish-brown to blackish-brown, globose to slightly compressed, up to 50 µm in diameter, with stellate warts and equal suspensor cells. Colony colour is a dirty grey rather than brown, and sporangia have spiny walls, are up to 50-60 µm in diameter, with columellae rarely larger than 30 µm in diameter. Growth is stimulated by thiamine, with no assimilation of sucrose and maximum temperature of growth is 54–58C. RG-1 organism. Key Features: growth at 45OC, the formation of numerous zygospores, a dirty grey culture colour and a partial growth requirement for thiamine. Mycosis: ZygomycosisFurther reading:Domsch, K.H., W.
