Ht. Lumbsch et al., THE JOINT OCCURRENCE OF CHLOROXANTHONES IN SOUTHERN-HEMISPHERE LECANORA SPECIES (ASCOMYCOTINA, LECANORACEAE), Botanica acta, 107(1), 1994, pp. 30-35
Four species belonging to the Lecanora subfusca group (Lecanoraceae, l
ichenized Ascomycotina) and containing the 2,5,7-trichloro-3-O-methyl-
norlichexanthone chemosyndrome are described: L. elixii Lumbsch, L. ep
ibryon Ach., L. mayrhoferi Lumbsch spec. nov. and L. parmelinoides Lum
bsch spec. nov. The species, which are interpreted as being closely re
lated, can be distinguished by a combination of subtle morphological a
nd anatomical characters.
