Chemical groups norstictic and salazinic. Acta Bot. Bras. [online]. 2010, vol.24, n.1, pp. 153-168. ISSN 0102-3306. http://dx.doi.org/10.1590/S0102-33062010000100015.
In a survey of the species pertaining to genera of large parmeliae occurring in the coastal areas of south-central São Paulo state, Brazil, nine species of Parmotrema sensu stricto (foliose thalli with rounded lobes usually more than 0,5 mm wide with nude lower margins) containing norstictic or salazinic acids as main medullar substances were found. These are typically recognized by the yellow then red staining potassium hydroxide spot tests. Identification key, descriptions, comments, and illustrations based on Brazilian material are provided for these species.
