Brazilian Lichens. Volume 7: Rondonia. 2024. illus. (col.). 665 p. gr8vo. Hardcover.

Rondônia (Brazilian Portuguese: [?õ'donj?] is one of the 26 states of Brazil, located in the northern subdivision of the country (central-western part) between latitudes 07º 58' 32" and 13º 41' 36" S and longitudes 59º 46' 26" and 66º 48' 21"W.

Rond8nia is a an Amazonian state bordering Bolivia. Although it is
5000 km from the see, it is already lowland at around 100 m altitude. In
2012, a collaborative project started to collect, identify and describe
lichens. Until then, there were only a handful of species know from the
state, mostly found in the herbarium on leaves that were collected for
the plants. By now it is, with Amazonas, the Amazonian state in which
the lichens are relatively best known. Rocks are rare, and usually
overgrown by mosses, cyanobacteria or lichens that are normally epi-
phytic. Terricolous lichens are also rare, and mostly resticted to termite
mounds, because the otherwise flat soul is always covered with a layer
of dead leaves. This book contains also some species from other re-
gions, in groups like Arthonia and Ocellularia where identification
work was not yet finished when the earlier books were published. All
specimens were collected under permits and the illustrated specimens
are duplicates of those preserved in ISE herbarium.
