Eschatogonia dissecta Timdal & R. Sant.

Abstract

Eschatogonia dissecta Timdal & R. Sant. This lichen was recently described by Timdal and reported from Peru, French Guiana and Venezuela (Timdal 2008). The material cited below matches the description by Timdal (2008) in all respects. We found homosekikaic acid and hyperhomosekikaic acid as major substances and sekikaic acid as a trace substance (TLC). The latter was not mentioned by Timdal. Eschatogonia dissecta is a new addition to the Brazilian lichen biota. Specimen examined:— BRAZIL.
