dig-ica-es-10261-324002019-08-06T09:49:18Z Fine structure of the Thalloconidia of the Lichen Genus Umbilicaria Ascaso, Carmen Sancho, Leopoldo G. Valladares Ros, Fernando Lichen Genus Umbilicaria 6 pages, figures, and tables statistics. The ultrastructure of the thalloconidia (asexual propágules of the mycobiont) in eight species of the lichen genus Umbiiicaria have been investigated. The selected species possessed thalloconidia corresponding to the three morphological types already described for the European flora. The study revealed for the first time the integrity of the cytoplasm in these propagules. Groups of well-differentiated concentric bodies, mitochondria with short and parallel cristae and vesicles coming from the endoplasmic reticulum were observed in the thalloconidia of U. decussata and U. havaasii. In some specimens of U. polyphylla, lipidie bodies filled most of the cytoplasm in the thalloconidia. In broad outline the ultrastructure observed in the thalloconidia was similar to that of the other mycobiont cells.
