A filamentous microorganism isolated from dental stain on a man's anterior teeth was studied. The literature pertaining to the genera Leptotrichia and Actinomyces is very confused since the opinions of investigators vary as to the characteristics of the microorganisms so classified. The identification of a filamentous organism is thus rendered difficult. The filamentous microorganism in question possessed properties peculiar to both genera. Its identification, however, as an actinomyees would seem to be indicated.
