Entoloma bloxamii, commonly known as the midnight blue entoloma,

IUCN Red List of Threatened Species.[1]

Taxonomy

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. It was transferred to the genus Entoloma by the Italian mycologist Pier Andrea Saccardo in 1887.[citation needed]

Recent

sensu stricto, Entoloma madidum (previously considered a synonym), E. atromadidum, E. ochreoprunuloides f. hyacinthinum, and an additional as yet unnamed species.[7] Collections from the west coast of North America, formerly referred to E. bloxamii or E. madidum, are also distinct[6] and are now referred to Entoloma medianox.[5]

Description

inamyloid, measuring about 7.5 to 9.5 by 7 to 9.5 μm.[6]

Similar species

Entoloma madidum is a deeper, slightly violet blue and retains some of its colour when old. Microscopically it has smaller spores (6 to 7.5 μm).[6] Entoloma atromadidum is similar but a darker, indigo blue and E. ochreoprunuloides f. hyacinthinum is dark brown with violaceous tints.[7]

Distribution and habitat

The Big Blue Pinkgill is rare but widespread in Europe.[1] Like many other European pinkgills, it occurs in old, agriculturally unimproved, short-sward grassland (pastures and lawns). It is usually associated with calcareous soils although it may also be found in more acidic areas.[8]

Conservation

Entoloma bloxamii is typical of waxcap grasslands, a declining habitat due to changing agricultural practices. As a result, the species is of global conservation concern and is listed as "vulnerable" on the IUCN Red List of Threatened Species.[1]
