Small, brown jelly lichen with white tufts of tomentum on lower surface (photo 4), isidia-like warts on upper surface, apothecia disks reddish-brown. Lobe tips rather thick and round. The thallus swells when wet: photo 2 dry, photo 3 wet.
Spores muriform, keys say 3 transverse septa and 1 longitudinal--I found more variation (see sketches in photo 6). Spore size matches keys.
