[5] Threats to its habitat have resulted in the Big Blue Pinkgill being assessed as globally "vulnerable" on the IUCN Red List of Threatened Species.

[1] The species was originally described from England in 1854 and named Agaricus Bloxami (sic) by Miles Joseph Berkeley and Christopher Edmund Broome, in honour of its collector, the naturalist and clergyman Andrew Bloxam.

The stipe (stem) is smooth, finely fibrillose, white with greyish blue streaks, often yellowish at the base, lacking a ring.

[6] Entoloma atromadidum is similar but a darker, indigo blue and E. ochreoprunuloides f. hyacinthinum is dark brown with violaceous tints.

[8] Entoloma bloxamii is typical of waxcap grasslands, a declining habitat due to changing agricultural practices.
