A cursory scan of web info on the genus indicates that it is predominant in the northern hemisphere in temperate areas. Known substrates include (but perhaps are not limited to) Abies, Acer, Larix, Malus, Picea, Pinus, Populus, Prunus, Quercus, Sequoia, and Tsuga. Its occurence in Latin America is probably very under-reported. NYBG’s Neotropical collection has four records of H. annosum, two from Mexico and two from Jamaica. Cybertruffle’s Fungi of the Dominican Republic (http://www.cybertruffle.org.uk/dorefung/eng/index.htm) lists four records, the Cuba list (http://www.cybertruffle.org.uk/cubafung/eng/index.htm) has five (4 annosum, one indet.) A look through Ryvarden’s Neotropical Polypores and other relevant texts would probably prove useful.

As a side note, seeing as H. annosum was the longtime catch-all taxon until intersterility studies revealed greater speciation within the genus, these records from the Neotropics likely represent several species of Heterobasidion.
