Eschatogonia dissecta Timdal & R. Sant. View in CoL

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.
