Field Notes
Description:
Lichen likes water. 2 pictures. On the left the lichen is hysrated. On the right the lichen lies on the ground, dehydrated. Lichens are composite organisms consisting of a symbiotic organism composed of a fungus (the mycobiont) with a photosynthetic partner (the photobiont or phycobiont), usually either a green alga (commonly Trebouxia) or cyanobacterium (commonly Nostoc).
Habitat:
This lichen was found on barren limestone rock during the recent Texas drought. Lichens are often the first to settle in places lacking soil, constituting the sole vegetation in some extreme environments. This lichen survives in the tough conditions of of the semi-arid Texas, and others on frozen soil of the Arctic regions.
