Streptothrix has frequently been found in the canaliculus (Morax1 and others), but its occurrence in other parts of the conjunctival sac has less commonly been observed. When present it usually produces granulomatous nodules on the bulbar conjunctiva (de Walsche,2 Denti3 and Liégard4) or on the retrotarsal folds (Bakly5). In the latter situation the resemblance of the lesions to trachomatous follicles has been noted by Morax6 and by Knapp and Dwyer.7 In Sicardi's8 case the fungus was found in the scratch made by the stem of a plant. When nodules are not formed, varying types of conjunctivitis are produced. Dombray and Gault9 reported a unilateral inflammation of the subacute catarrhal type. The infections described by di Fede10 and de Logu11 were also unilateral but were largely confined to the angles and were characterized by abundant mucoid secretion. Membrane formation was
