As far as I remember, my tentative ID was based just on the fact it grew on rocks – I didn’t examine micro features, let alone taken a sample at that time.
Andrew, here are some notes to go with your checklist.
Key (after Thompson, 2003, pp.221-222):
1a. Primary thallus persisting, pseudopodetia growing between primary squamules, on sand and earth; collected once in WI in 1894, and now thought to be extinct in WI … Stereocaulon condensatum
1b. Only pseudopodetia, primary thallus disappearing … 2
2a. On rocks; little or no tomentum; cephalodia rare, inconspicuous … Stereocaulon saxatile
2b. On sand, earth, clay or dirt over rocks; tomentum well developed; abundant cephalodia … 3
