These things seem to grow in arid places with dew, if I remember right.
man these guys are always so tricky in the field, at least for me. I wonder if the cerebellum type folds, do they help channel water or dew somehow into the lichen…?
Have you read about those beetles in the Nambian desert? Basically, from what I remember from Molles´ Ecology text from a few years ago, these beetles will climb up into a sand hill, and they´ll position themselves with their body´s facing down the slope so that the condensed fog from the ocean will drip down the longitudinal crevice in their backs and into their… um, beetle-mouth.
So I wonder if these brain like convolutions in the crusts assist with condensing and capturing humidity from the air and assisting the lichen thallus to absorb it into the thallus…
