Baja California Sur is an arid state in northwest Mexico. Suitable hab
itats for macrofungi are restricted to an isolated mountainous region
in the extreme south where these kinds of organisms seem to be as dive
rse as those in similar communities in the woodlands of mainland Mexic
o. Only a few taxa could be found in the widespread desert environment
of the lowlands. This study adds 63 taxa to the previous macromycete
listings of Baja California Sur.
