Abstract
C. spinosus occurs in nature chiefly on dead and disintegrating vegetation and may be readily cultured on bits of dried onion skin, leaves of grass and other substrata of this type. Unlike C. aureus and C. hyalinus, it is not markedly chitinophilic in its nutrient requirements. It differs structurally from these spp. by the presence of numerous abruptly tapering spines on the surface of the sporangia and resting spores, and by slightly smaller zoospores. Its life cycle and type of development, however, are similar to those of C. aureus and C. hyalinus.
