| endolithic growth of two lecidea lichens in granite from continental antarctica detected by molecular and microscopy techniques. | through the combined use of molecular and microscopy techniques, the endolithic lichens lecidea cancriformis and lecidea sp. were identified, even in the absence of fruiting bodies, and positioned under epilithic lichens. cells of both algal and fungal symbionts were observed in fissures and cracks of the lithic substrate with no clear heteromerous structure. at the ultrastructural level, the two lichens differed in terms of their algal-fungal relationships. only one genotype of trebouxia its se ... | 2005 | 15720632 |
