Recognized by sight: Sometimes the red tips look quite brown in photos and can fool you. But I think this is the best name given that we can’t do a definitive KC test to verify lack of usnic acid.

I’ve removedthe first photo. There is no red on this species so, according to your note, it is probably Cladonia pyxidata. Should we name it that?


Two species of Cladonia

The first photo looks like maybe C. coniocraea: finely sorediate except at base of stalks, stalks arising from center of relatively large squamules. But you could also check C. rei or maybe even C. subulata, I suppose.

The second two photos show a species with cupped stalks and microsquamules instead of soredia. It may even have reddish tips. If red, try C. borealis or C. coccifera; if brown try C. pyxidata.
