Hygrocybe spadicea is a species of agaric (gilled mushroom) in the family Hygrophoraceae. It has been given the recommended English name of Date Waxcap. [2] 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. [1]

Taxonomy

The species was first described from Carniola (present-day Slovenia) in 1772 by naturalist Giovanni Antonio Scopoli as Agaricus spadiceus. Finnish mycologist Petter Adolf Karsten transferred it to the genus Hygrocybe in 1879.

Recent molecular research, based on cladistic analysis of DNA sequences, has confirmed that Hygrocybe spadicea is a distinct species and belongs in Hygrocybe sensu stricto. [3]

Description

Basidiocarps are agaricoid, up to 90 mm (5 in) tall, the cap conical at first, retaining an acute or distinct umbo when expanded, up to 80 mm (3 in) across, often splitting at the margins. The cap surface is smooth, dry, and radially fibrillose, brown and typically darker at the apex. The lamellae (gills) are waxy, yellow to yellow-orange. The stipe (stem) is smooth, somewhat fibrillose, yellow at first with brownish streaks when older, lacking a ring. The spore print is white, the spores (under a microscope) smooth, inamyloid, ellipsoid, measuring about 9 to 12 by 5 to 7  μm. [4]

Distribution and habitat

The Date Waxcap is widespread but generally rare throughout Europe. It has also been reported from Central Asia (Kazakhstan), but its identification has not been confirmed. [1] Like other waxcaps, it occurs in old, agriculturally unimproved, short-sward grassland (pastures and lawns).

Recent research suggests waxcaps are neither mycorrhizal nor saprotrophic but may be associated with mosses. [5]

Conservation

Hygrocybe spadicea 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] Hygrocybe spadicea also appears on the official or provisional national red lists of threatened fungi in several European countries, including Croatia, [6] Czech Republic, [6] Denmark, [7] Estonia (where it is listed as "extinct"), [6] Finland, [6] Germany, [8] Great Britain, [9] Norway, [6] and Sweden.

<i>Hygrocybe</i> Genus of fungi

Hygrocybe is a genus of agarics in the family Hygrophoraceae. Called waxcaps in English, basidiocarps are often brightly coloured and have dry to waxy caps, white spores, and smooth, ringless stems. In Europe they are characteristic of old, unimproved grasslands which are a declining habitat, making many Hygrocybe species of conservation concern. Four of these waxcap-grassland species, Hygrocybe citrinovirens, H. punicea, H. spadicea, and H. splendidissima, are assessed as globally "vulnerable" on the IUCN Red List of Threatened Species. Elsewhere waxcaps are more typically found in woodlands. Most are ground-dwelling and all are believed to be biotrophs. Around 150 species are recognized worldwide. Fruit bodies of several Hygrocybe species are considered edible and are sometimes offered for sale in local markets.

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

Hygrocybe conica is a species of agaric in the family Hygrophoraceae.
