Apodetiate Cladonia

…are impossible. On the east coast James Lendemer and Richard Harris have put together some fairly good keys to them (and there are a lot more species there). But I haven’t found anything good on the west coast, yet. I don’t know if there are actually any species which essentially never have podetia on the west coast. However, there are at least a few species which you can often find in extensive sterile patches. Unfortunately it requires someone with extensive field experience in the area in question to know which species do that; it’s not always mentioned in the literature. I think taxonomists mostly only look at the (very) biased sample of fertile specimens!

I’ve seen two sterile species several times in southern California: C. maritima and another I haven’t been able to determine. But the one is strictly southern and coastal, the other has very small squamules. I know C. cariosa (mostly northern) is often sterile, but I wouldn’t expect it on a rock. Other species mentioned in a key to northwestern apodetiate species (from Trevor Goward) include C. pyxidata (scales mostly decumbent), C acuminata and C. verticillata group (scales erect, the latter almost always has at least a few cups proliferating from the center, though, in my experience).

You might be able to improve the odds a bit with spot tests (the usual KC on cortex and K on white underside of squamules). If you get a good KC+ gold, then none of the above suggestions are correct! and there’s another set to consider.
