![]() 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. Its lamellae distinguish it from other members of the "L. vinaceobrunnea" in a number of characteristics, but the fresh sporocarp is a darker purple than either "L. This species is associated with "Quercus" and is endemic to the cloud forests of Central America and northern South America. In 1988, a third species of purple "Laccaria", "Laccaria gomezii", was described by Mueller as distinct from "L. amethystina" is also often associated with this species, but is associated with many other tree species in the Fagales as well. vinaceobrunnea" is also somewhat distinguished by habitat, being highly specific in association with "Quercus virginiana". ![]() 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". amethysteo-occidentalis" and long spines characteristic of "L. amethysteo-occidentalis", having a subglobose to broadly ellipsoid shape like "L. Its spore features are intermediate between "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. vinaceobrunnea" is distinguished from "L. amethystina" is "Laccaria vinaceobrunnea", a species found in the Gulf Coast region of the southern United States. amethystina".Īnother species that was segregated by Mueller from "L. amethystina", being generally of a subglobose or even broadly ellipsoid shape, and additionally having much shorter spines than the spores of "L. amethysteo-occidentalis" are not as strongly globose as those of "L. The spores are also quite distinct between the two, in that the spores of "L. amethystina", and has a deeper purple coloration, that fades to vinaceous rather than brownish shades. amethysteo-occidentalis" is on average larger than that of "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. amethysteo-occidentalis" differs from "L. It is a very common mushroom in its geographical range. "Laccaria amethysteo-occidentalis" is found in western North America, where "L. Mueller described them as distinct species in 1984. There are several purplish species in North America that were formally labeled as "L. The basidia, the spore-bearing cells, are club-shaped and hyaline, and are 30–64.5 by 8.5–14 µm. ![]() 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 flesh is without a distinctive taste or smell, and is thin, with pale lilac coloration. 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 stem is the same colour as the cap, and has whitish fibrils at the base, which become mealy at the top. It is sometimes slightly scurfy at the center, and has pale striations at the margin. When moist it is a deep purplish lilac, which fades upon drying out. The cap is 1–6 cm in diameter, and is initially convex, later flattening, and often with a central depression. ![]()
