Some taxonomic placements

[Gene Yetter]

Can anyone help in placing the following genera in their proper groupings:

Family, order, class.....Gastroboletus, Gomphus, Hygrophoropsis
Family.....Phaeolepiota
Division through family.....Gloeodontia, Heliomyces.

.....why (or according to which authority)?

Looking over my database, I see that I have dual interpretations, or
nothing at all.  I would like to correct that situation.
