 Like all species remaining in the genus Collybia , C. cirrhata is saprobic , and is typically found growing on the decaying or blackened remains of other mushrooms ; occasionally the fruit bodies may be found growing on moss or soil without any apparent connection to decaying mushrooms , although these observations may represent instances where the remnant host tissue — possibly from a previous season — has decayed to such an extent that it remains as buried fragments in the substrate . Known hosts include Lactarius , Russula , Meripilus giganteus , and Bovista dermoxantha .
