Notes. – Diplasiolejeunea brunnea is a widespread neotropical species that is distinguished by ocellate leaves without hyaline margin, large lobules with a conspicuous, erect, fingerlike first tooth and an inconspicuous second tooth, and by deeply bifid underleaves with widely diverging, lanceolate lobes with acute tips (REYES, 1982). Diplasiolejeunea bidentiloba, known only from the type collected by Allioni, is identical to D. brunnea . The new synonymy was already noted by R. Grolle (in sched.).
