About 200 species have been identified from among over 1,500 collections.  These include at least fifteen new species that have been described from the gulf coast, some of which are extremely common.  For example Hyphoderma baculorubrense and Perenniporia phloiophila are to be found on almost every mature live oak (Quercus virginiana) tree throughout its natural range from Texas across the gulf coast and northwards along the east coast at least as far north as Charleston, North Carolina. Inonotus quercustris, a polypore with a large basidioma, is common on the main stem and lower branches of living water oaks (Quercus nigra) across the gulf coastal plain and Ganoderma meredithiae is a common root-rotting basidiomycete of pines.  Other common fungi that have never or only rarely been reported in the United States or North America include Marasmiellus juniperinus, Ganoderma colossum,and Laetiporus perscinus.

Inonotus quercustris AL, FL, LA: Quercus nigra Inonotus quercustris on a water oak tree that grew on Steele Boulevard near its intersection with Broussard Street.  The tree and the fungus were cut in order to "beautify" a Baton Rouge residentual area. Live oaks have been planted in place of the heart-rotted water oaks.  This was the first specimen to be discovered, but luckily the species is common in water oaks along the Gulf Coast.  It also has been reported from Argentina.  The tree that bore the type specimen grew nearby and also was cut down about 1999 by a Baton Rouge beautification group.

Laetiporus sulfureus LA: Quercus.   Laetiporus sulphureus is one of the few common brown rot fungi of hardwoods. A second species, L. persicinus, causes a root rot that is common in the Baton Rouge area on live oak, and this less well known species probably is circumtropical.
