Abstract: 9 fig. 3 tab. ["The green algal symbionts of the lichenized fungus Letharia are identified as members of the morphospecies Trebouxia jamesii, based on ITS sequences that place them in a molecularly diverse clade with other lichen algae also identified as T. jamesii. However, based on additional sequence from a second locus, actin, T. jamesii is seen to consist of many phylogenetic species. A clade of six to seven closely related phylogenetic species of T. jamesii are symbiotic with five of the six phylogenetic species of Letharia." Actual date of publication 9 Jan. 2001.]
