Notes

Gomphidius has a gelatinous universal veil, so the young fruiting bodies are covered in a transparent slime. The partial veil is also gelatinous, when present.

This genus is quite easy to identify in the field. It might be confused with Chroogomphus, but we have yet to encounter that genus in this area.
