[7] The spores of L. umbrinum are spherical and either smooth or ornamented[8] with spines and appear olive yellow in KOH.

[5] Be sure to identify properly before eating because it could be confused with the toxic earth ball or deadly Amanita.

Additionally, there were development of branched and finger-like mycorrhizae underneath the L. umbrinum fruiting bodies.

[4] This study was done in South Africa where it is common that coniferous plants grown on large scale have this mutualism (and L. umbrinum is one of them).

[15] It was found that Aspergillus tamarii (an endophytic fungus) is associated with L. umbrinum through a beneficial mutualistic relation.

[14] This fungus, extracted from L. umbrinum has significant antibacterial properties specifically on Salmonella typhi, Staphylococcus aureus, Bacillus subtilis, and Escherichia coli.

[14] L. umbrinum was also found to have antimicrobial activities against methicillin resistant Staphylococcus aureus (MRSA).

[13] Lycoperdon umbrinum contains tocopherols with α- and β- isoforms and has high ash content (indicating it has minerals important for nutrition).
