[7][8] It has been found that the Hebeloma genus phylogenetic data may be "related to saprotrophic species in the genera Agrocybe or Pholiota".

[9] H. cylindrosporum can also associate with other hosts such as Larix laricina, Dryas integrifolia, and Quercus acutissima in a laboratory.

In one study, it was found that H. cylindrosporum has two genes that are "involved in metal homeostasis and detoxification".

[14] Another study involving cadmium and H. cylindrosporum found that an enzyme made by the fungus increased the production of "a core component in the mycorrhizal defense system under Cd stress for Cd homeostasis and detoxification".

[16] This study found that the fungi "transfer of soil As to plant roots by conjugating it with gluthathione and accumulating inside the vacuoles".

[16] The researchers conclude "that H. cylindrosporum is efficient in dealing with As stress and may offer global potential in its bioremediation".
