Abstract:  The taxonomic status and podetial morphology of Cladonia luteoalba A. Wilson & Wheldon have been re-examined. The species commonly grows on podetia of other related lichens, in particular C. coccifera (L.) Willd., C. borealis Stenroos and C. metacorallifera Asah., with which it is apparently able to form commensalistic symbioses. Its true podetia are escyphose, decorticate, rudimentary structures, never found with hymenia. Earlier, the podetia of the host lichens have been misinterpreted as podetia of C. luteoalba. The species comprises four major chemotypes: (1) the zeorin strain, (2) the barbatic acid strain, (3) the squamatic acid strain, and ( 4) the fumarprotocetraric acid strain. The distribution of the major chemotypes is mapped. The species is reported as new to Japan, China, India, Idaho and S. Finland.
