Gomphidius glutinosus, commonly known as the slimy spike-cap, hideous gomphidius, or glutinous gomphidius

gilled mushroom found in Europe & North America. Although it has gills, it is a member of the order Boletales, along with the boletes. The fruiting bodies sprout in pine, fir and spruce woodland in Europe in autumn. Initially, are completely covered with a slimy veil, breaking through to reveal a greyish or brownish-capped mushroom with decurrent greyish gills which sometimes resembles a child's top
. Opinions differ on the suitability of this mushroom for the table, some guides hold it in high regard, while others view it with caution.

Taxonomy

Gomphidius glutinosus was initially described by

specific epithet glutinosus is the Latin adjective "sticky".[4]

British botanist Samuel Frederick Gray described Cortinaria viscida the "viscid curtain-stool" in his 1821 work A natural arrangement of British plants,[5] concluded by Orson K. Miller Jr. to be the same species.[6]

In 1971, Miller described two varieties: G. glutinosus var. purpureus from a specimen collected near Nordman, Idaho. More drab purple to wine-coloured, this taxon is native th the Rockies in Idaho, Montana and Alberta. G. glutinosus var. salmoneus was described from Kaniksu National Forest in Idaho. With a salmon-coloured cap, it is native to northern and central Idaho as far south as Payette National Forest.[6]

Alternate common names in Germany are Kuhmaul "cow snout",[4] and Rotzer.[7]

Description

young mushroom

Said to resemble a child's

cystidia.[7] Sometimes branched, they are initially whitish, then grey and later blackening with spores. The spore print is brownish-black. The large spores are spindle-shaped and measure 17–20 μm long by 5.5–6 μm wide.[9]

Similar species

Brownish specimens may be mistaken at a glance for Suillus luteus, but a look under the cap will see there are gills rather than pores.[10] Another similar-looking species is Hygrophorus hypothejus, found in similar habitat though with yellow gills which do not separate from the cap.[9][11] The North American species Gomphidius smithii is similar but has a pale purple to wine-coloured cap.[6]

Other similar species include Gomphidius oregonensis and Gomphidius subroseus.[8]

Distribution and habitat

Gomphidius glutinosus is found in Eurasia and North America up to elevations of 9600 ft, and is generally abundant across its range. It occurs in autumn under various species of conifer—both in natural woods and plantations—such as balsam fir (Abies balsamea), Norway spruce (Picea abies) and grand fir (Abies grandis). The mushrooms may be single, scattered, or occasionally growing in clumps.[6] Fruiting bodies sprout in the autumn,[9] to as late as December in northern California.[6]

Ecology

Like other members of the family Gomphidiaceae, Gomphidius glutinosus has been thought to be

boletes, in relationships that are often highly species-specific, such as Gomphidius roseus upon Suillus bovinus.[12]

Two specimens of Gomphidius glutinosus were found in Brechfa Forest on the 25th Of July 2009. The only boletus to be found in the vicinity was Suillus grevillei.

G. glutinosus is a hyper-

cesium-137.[13]

Edibility

Opinions differ on the suitability of this mushroom for the table, some guides hold it in high regard,[11] while others view it with caution.[9] Gomphidius glutinosus has a mild flavour well-suited for cooking with other mushrooms, and in soups and stews.[7] It is not suited for drying. Removing the slime and skin of the cap is recommended as soon as possible after picking. Maggots only rarely attack this species.[7]
