My species

 "One caution is that we confirm Lindblom (2006) that there are common morphological overlaps between  Xanthomendoza galericulata and Xanthomendoza fulva that may make absolute field identification, as indicator species, more difficult."  (Rogers et al. 2007. Aspen Indicator Species in Lichen Communities in the Bear River Range of Idaho and Utah. Evansia 24(2): 34-41.)
