Amethyst Deceiver

Laccaria amethystina

''Laccaria amethystina'', commonly known as the Amethyst Deceiver is a small brightly colored, edible mushroom, that grows in deciduous as well as coniferous forests. Because its bright amethyst coloration fades with age and weathering, it becomes difficult to identify, hence the common name ‘Deceiver’.

Appearance

The cap is 1–6 cm in diameter, and is initially convex, later flattening, and often with a central depression . When moist it is a deep purplish lilac, which fades upon drying out. It is sometimes slightly scurfy at the center, and has pale striations at the margin. The stem is the same colour as the cap, and has whitish fibrils at the base, which become mealy at the top. It is fibrous, hollow, fairly tough when rolled in the fingers, with dimensions of 0.6 to 7 centimetres long by 0.1 to 0.7 centimetres thick. The flesh is without a distinctive taste or smell, and is thin, with pale lilac coloration. The gills are colored as the cap, often quite distantly spaced, and are dusted by the white spores; their attachment to the stem is sinuate—having a concave indentation before attaching to the stem.The spores are spherical, hyaline, and bear pointed spines that are long relative to the size of the spore; they typically have dimensions of 7–10 by 7–10 µm. The basidia, the spore-bearing cells, are club-shaped and hyaline, and are 30–64.5 by 8.5–14  µm .

Naming

There are several purplish species in North America that were formally labeled as ''L. amethystina'' before Gregory M. Mueller described them as distinct species in 1984. ''Laccaria amethysteo-occidentalis'' is found in western North America, where ''L. amethystina'' does not occur. It is a very common mushroom in its geographical range. Besides geographical difference, ''L. amethysteo-occidentalis'' differs from ''L. amethystina'' in several ways: ecologically, the former occurs only in association with conifers, while the latter occurs mainly with hardwoods of the order Fagales. The sporocarp of ''L. amethysteo-occidentalis'' is on average larger than that of ''L. amethystina'', and has a deeper purple coloration, that fades to vinaceous rather than brownish shades. The spores are also quite distinct between the two, in that the spores of ''L. amethysteo-occidentalis'' are not as strongly globose as those of ''L. amethystina'', being generally of a subglobose or even broadly ellipsoid shape, and additionally having much shorter spines than the spores of ''L. amethystina''.

Another species that was segregated by Mueller from ''L. amethystina'' is ''Laccaria vinaceobrunnea'', a species found in the Gulf Coast region of the southern United States. ''L. vinaceobrunnea'' is distinguished from ''L. amethystina'' and ''L. amethysteo-occidentalis'' macroscopically by color, with the former species having a deep purple color only in very young specimens, which soon fades to a violaceous- or reddish-brown color, and eventually to dull orange-brown or buff color with age. Its spore features are intermediate between ''L. amethystina'' and ''L. amethysteo-occidentalis'', having a subglobose to broadly ellipsoid shape like ''L. amethysteo-occidentalis'' and long spines characteristic of ''L. amethystina''. The pileipellis of ''L. vinaceobrunnea'' is unique within ''Laccaria'', having a distinct palisadoderm, rather than the undifferentiated type or fasciculate trichoderm that is characteristic of other species of ''Laccaria''. ''L. vinaceobrunnea'' is also somewhat distinguished by habitat, being highly specific in association with ''Quercus virginiana''. ''L. amethystina'' is also often associated with this species, but is associated with many other tree species in the Fagales as well.

In 1988, a third species of purple ''Laccaria'', ''Laccaria gomezii'', was described by Mueller as distinct from ''L. amethystina''. This species is associated with ''Quercus'' and is endemic to the cloud forests of Central America and northern South America . ''L. gomezii'' is similar to ''L. vinaceobrunnea'' in a number of characteristics, but the fresh sporocarp is a darker purple than either ''L. vinaceobrunnea'' or ''L. amethystina''. Its lamellae distinguish it from other members of the ''L. amethystina'' group, with ''L. gomezii'' having attached to subdecurrant, very closely spaced lamellae, in contrast to the sinuate to arctuate, narrowly attached lamellae of other species in this group. The spores of ''L. gomezii'' are similar to those of ''L. vinaceobrunnea'' and ''Laccaria amethysteo-occidentalis'', and it lacks the distinct pileipellis hyphae of ''L. vinaceobrunnea''

Distribution

''L. amethystina'' is a common species in most temperate zones of Europe, Asia, Central, South, and eastern North America. It grows solitary to scattered with a variety of deciduous and coniferous trees, with which it is mycorrhizally associated, though it most commonly occurs with trees in the Fagales. It appears in late summer to early winter, and often with beech; in Central and South America, it more commonly grows in association with oak. Research has shown that ''L. amethystina'' is a so-called "ammonia fungus", an ecological classification referring to those fungi that grow abundantly on soil after the addition of ammonia, or other nitrogen-containing material; the congeneric species ''Laccaria bicolor'' is also an ammonia fungus.

Laccaria amethystina Long, thin stipes with tiny caps -- I'm guessing they were immature.

Habitat: Adirondack Mountains -- I'm not sure what the exact location was because we were mountain hiking.

*The Adirondack mountains are located in northeastern New York and contains more than 6 million acres of forests, including mountains, wetlands, and old-growth forests. Amethyst Deceiver,Geotagged,Laccaria,Laccaria amethystina,Summer,United States,fungus,mushrooms

Cultural

The post-industrial band Coil took the title of one of their songs, "Amethyst Deceivers", from the common name of this mushroom.
