Within the Basidiomycota, there are several more than the 16 orders represented below. These sixteen feature fungi predominant in our temperate region of northeast North America. Within each order are between one and numerous families. Again, not all families are included from each order, because we either do not have fungi belonging to the unnamed/excluded families or we do not have photos of local fungi belonging to these familes. Within each listed family are between one and numerous genera and species represented. As I discover and am able to correctly identify additional fungi belonging to these or new families, I will post them on line in accordance with the most currently accepted names and family associations as indicated in INDEX FUNGORUM and MYCOBANK.
Although not nearly as numerous as fungi in the Ascomycota, most members of the Basidiomycota are macro-fungi and are generally more visible representatives of the fungal kingdom in the eyes of fungi explorers.
With Basidiomycetes spores are produced and held within projecting club-like cells call sterigmata. In most cases, each basidium consists of 4 sterigmata projections and four spores (again, there are exceptions to this statement).
