– candy-corn mycena
Distribution: Coniferous forests in western North America.
Habitat: Coniferous forests with Pseudotsuga, Tsuga and Pinus.
Substrate: Soil.
– conifer-cone baeospora, conifercone cap, conifer conecap, spruce-cone mushroom
Description: Small, tan to whitish cap with crowded, white gills and white to brownish stalk; on fallen conifer cones
Substrate: Spruce and Douglas fir cones
Spores: September to October
– lavender baeospora
Description: Fresh specimens are quite striking when plucked from a log and turned over to reveal the crowded, narrow, lilac gills. The thin-fleshed caps and the stipes are usually brownish, occasionally with lilac tones, and develop grayish or paler tones with age or loss of moisture. The tough, hollow stipe is usually somewhat pruinose above and has white short hairs on the base. B. myriadophylla is an uncommon fungus and usually occurs in small numbers in fall or spring.
Substrate: Hardwood logs and stumps
Spores: June to October
– black and white clitocybula
Habitat: C. atrialba is a western species that occurs singly on the (sometimes buried) wood of alder and perhaps other hardwoods.
Substrate: Wood or woody debris
Spores: whitish amyloid spores
– cucumber cap, cucumber-scented mushroom
Distribution: Usually found in nutrient-rich soils among herbaceous plants in gardens and parks rather than in forests (although it can occur there, usually along trailsides).
Distribution: Northern hemisphere.
Habitat: Forests and woodlands.
Substrate: Leaf litter and woody debris on ground.
– horsehair fungus, horsehair parachute
– leaf parachute, white pinwheel
– fairy ring champignon, fairy ring mushroom
Distribution: The most common species in the PNW, M. oreades, occurs in many parts of the world in lawns, parks, pastures, and other grassy areas, where it often grows in arcs or circles known as fairy rings.
– velvet-cap Marasmius, pleated mushroom
– angel's-wings
Distribution: Found on conifer (especially hemlock) logs and stumps throughout the PNW, often occurring in large, exquisite, imbricate masses
– butter-cap, buttery Collybia
Habitat: Conifer forests
Spores: pale pinkish buff, relatively large (mostly 7-9 x 3.5-4 µm) and tear-shaped, almond-shaped, or ellipsoid
– spotted Collybia, spotted toughshank
Substrate: Clusters on or near rotting conifer wood
