What look like lichen hyphae embedded in the soil around fossils from the pre-Cambrian or Ediacaran Period (635-541 million years ago) suggest that lichens may have been the first pioneers on dry land. It is also believed that some chemicals act to coat sections of hyphae to provide air pockets necessary for photosynthesis by the algae. Published by the author: Don Flenniken, 2273 Blachleyville Rd., Wooster, Ohio 44691. The rounded lobes, measuring 38mm (0.10.3in) wide, usually have patches of granular soredia arising from pustules. The lichen looks different than the way the fungus or algae looks by itself. Luckily for those of you who live in cities, this lichen is relatively tolerant of pollution (in comparison to other lichens). However, having a place to live with enough water and air for photosynthesis to make carbohydrates and respiration to oxidize them for energy (both plants and fungi need to breathe) is certainly an algal advantage. Everyone has a favorite band or artist, but are few people who listen to the entire album. 2004. Description. It is surmised that they contribute to shielding green algae from excessive sunlight exposure since bright sun is inimical to photosynthesis, the source of all lichen energy. Thesis.
