On base of a Chinese(?) fan palm just inside spray zone of sprinklers. On Bellfontaine between St John and Orange Grove.

THALLUS: apparently lacking, also apparently no medulla

I’m told the waxy appearance of the apothecia is typical for this species. This is the first time I’ve seen this in southern California.
