Re : A Phylacia from Panama
Have no idea of this genus, but a key is available here:

Medel, R.; Rogers, J.D.; Guzman, G. (2006) - Phylacia mexicana sp.nov. and consideration of other species with emphasis on Mexico. Mycotaxon 97: 279-290.

Re : A Phylacia from Panama
Hi Eduardo,
nice find and nice photos, very informative. Externally the best match seems to be P. globosa, already known from Panama, but it would help to have also the spores dimensions. Better to record them on spores accumulating at the top of the stroma just beneath the crust because they are mature and pale brown, unlike the ones you recorded. The paper by Medel et al. is useful but unfortunately they did not record and use in their key the pigments released by the stroma in 10% KOH. They vary from shades of olivaceous to purplish and they are highly diagnostic. Just pick up a small chip of the external crust of mature stroma and put in in a drop of KOH, you should get a nice reaction within a minute.
Cheers,
Jacques
