BENATTI, Michel Navarro  and  MARCELLI, Marcelo Pinto. Species of Parmotrema sensu strict (Parmeliaceae, Ascomycota) from the central-southern coast of São Paulo state II: Chemical groups equinocarpic and stictic. Acta Bot. Bras. [online]. 2010, vol.24, n.2, pp. 304-321. ISSN 0102-3306.  http://dx.doi.org/10.1590/S0102-33062010000200002.

In a survey of the species pertaining to genera of large parmeliae occurring in the coastal areas of the central-southern coast of São Paulo state, Brazil, seven species of Parmotrema sensu stricto (foliose thalli with rounded lobes usually more than 0.5 mm wide with nude lower margins) containing equinocarpic or stictic acids as the main medullar substances were found. These are typically recognized by the strong yellow- staining potassium hydroxide spot test. An identification key, descriptions, comments, and illustrations based on Brazilian material are provided for these species.
