Recognized by sight: Cheimonophyllum candidissimum has a stipe, which I do not see in the photos, whereas Rimbachia bryophila has no stipe. Also, The former grows on wood, yet the latter grows in association with moss… These are growing from wood and moss, but the absent stipe is what makes me pretty confident it is R. bryophila.

Rimbachia bryophila it is!

No stipe; and that stick (from which one was fruiting) might have been an anomaly; when I pulled the dirt clod apart to stick them on the dryer, there were no other bits of wood underneath the moss.
Thanks, guys. Cool little (and I do mean little) shroom.

Rimbachia & Cheimonophyllum

Cheimonophyllum does have a stipe…if these are stipeless, then Rimbachia bryophila is a better choice. Rimbachia bryophila is much more common locally than Cheimonophyllum candidissimum.
