Abstract: [Study of 87 thalli from 11 sites in the Eastern United States. "Four associated algal [Asterochloris] clades were found. Analysis of molecular variation (ANOVA) and partial Mantel tests suggested that the frequency of associated algal genotypes was significantly different among sites and habitats, but at random with respect to fungal genotypes and clade. Fungal genotypes were not structured according to site and appeared to be recombining. We suggest that ecological specialization exists for a specific lichen partnership and a site, and that this selectivity is dynamic and environmental-dependent."
