Entoloma bloxamii, commonly known as the midnight blue entoloma, [3] or big blue pinkgill, [4] is a species of agaric (gilled mushroom) in the family Entolomataceae. The species has a European distribution, occurring mainly in agriculturally unimproved grassland. [1] Entoloma bloxamii has been reported from North America, but at least some of these reports represent a distinct species, Entoloma medianox . [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]

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 molecular research, based on cladistic analysis of DNA sequences, has shown that Entoloma bloxamii sensu lato comprises a number of distinct blue taxa in Europe, [6] including Entoloma bloxamii 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

Basidiocarps are agaricoid, up to 45 mm (1.75 in) tall, the cap conical becoming convex to conical, up to 50 mm (2 in) across. The cap surface is smooth, pale greyish blue at first becoming greyish brown. The lamellae (gills) are white becoming pink from the spores. The stipe (stem) is smooth, finely fibrillose, white with greyish blue streaks, often yellowish at the base, lacking a ring. The spore print is pink, the spores (under a microscope) multi-angled, 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]

<i>Hygrocybe conica</i> Species of fungus

Hygrocybe conica is a species of agaric in the family Hygrophoraceae. In the UK it has been given the recommended English name of blackening waxcap, since all parts of the basidiocarp blacken with age. In North America it is commonly known as the witch's hat, conical wax cap or conical slimy cap. Hygrocybe conica is known to be a complex of at least eleven closely related species and as such is widespread in Europe, North America, Asia, and elsewhere.

<i>Hygrocybe punicea</i> Species of fungus

Hygrocybe punicea is a species of agaric in the family Hygrophoraceae. It has been given the recommended English name of crimson waxcap. The species has a European distribution, occurring mainly in agriculturally unimproved grassland. Threats to its habitat have resulted in the species being assessed as globally "vulnerable" on the IUCN Red List of Threatened Species. Records of H. punicea from North America, East Asia, and Australia require further research to see if they represent the same species.

<i>Entoloma</i> Genus of fungi

Entoloma is a genus of fungi in the order Agaricales. Called pinkgills in English, basidiocarps are typically agaricoid, though a minority are gasteroid. All have salmon-pink basidiospores which colour the gills at maturity and are angular (polyhedral) under a microscope. The genus is large, with almost 2000 species worldwide. Most species are saprotrophic, but some are ectomycorrhizal, and a few are parasitic on other fungi. The type, Entoloma sinuatum, is one of several Entoloma species that are poisonous, typically causing mild to severe gastrointestinal illness.

<span class="mw-page-title-main">Waxcap grassland</span> Type of grassland

Waxcap grassland is short-sward, nutrient-poor grassland that supports a rich assemblage of larger fungi, particularly waxcaps, characteristic of such habitats. Waxcap grasslands occur principally in Europe, where they are declining as a result of agricultural practices. The fungal species are consequently of conservation concern and efforts have been made in the United Kingdom and elsewhere to protect both the grasslands and their characteristic fungi. Over 20 species of European waxcap grassland fungi are assessed as globally "vulnerable" or "endangered" on the IUCN Red List of threatened species.
