Past foray species lists provide an interesting resource to examine macrofungal diversity and distribution, however these data are not documented by voucher specimens. This prevents verification of identifications and accurate interpretation of species concepts that have undergone taxonomic changes.

Lists from most of the NAMA forays have been compiled into a database that includes synonyms and species maps showing foray records. Preliminary data on the analysis of species lists for 31 forays was presented at the International Botanic Congress, St. Louis, MO, 1-7 August, 1999. A small single page version of the poster can be viewed in this PDF file (requires the free Adobe Acrobat Reader).

This graph shows the Species Curve for the NAMA Forays with an accumulation of over 2600 fungi names. This species curve resembles a line because it has not yet begun to level off for 36 samples!! There are perhaps an estimated 10,000 macrofungi for North America.

We are missing species lists for these NAMA forays: 1961 OH, 1967 MI, 1983 CO, 1984 ON, 1985 WV, 1993 WA, 1996 VT.
