(Panaeolus subbalteatus)
Habitat: Occurs on dung (often of horses) or dung-rich soil in gardens or lawns.
(Amanita pantherina)
Description: Like clock-work in late winter to early spring, an amanita in the Amanita pantherina complex appears, especially in urban areas. Other members of this group fruit through summer and fall in a variety of habitats. They come in a variety of color forms, from pale yellowish tan ones that are similar to A. gemmata to dark brown ones that are more like classical European A. pantherina. The mushrooms are medium-sized or larger, the cap has striations on the margin, and the universal veil leaves conspicuous whitish warts and patches on the cap and a close-fitting volva with a distinct free rim (like slightly rolling back the top of a sock) around the bulbous stipe base. The gills are white and closely spaced, and the partial veil is white and leaves a skirt-like ring on the stipe. Here, again, applying a European name to a western North American mushroom might be incorrect. Our mushrooms may well not be “real” A. pantherina.
Distribution: Broad
Habitat: woodlands, rarely in pastures
Substrate: broadleaf trees
Spores: late winter to early spring

(Tapinella atrotomentosa)
Habitat: Grows from rotting conifer stumps, snags, and logs
(Clavariadelphus sachalinensis)
Description: Clavariadelphus sachalinensis is one of several small slender members of the genus that are characterized by fruiting from a dense mycelial mat that permeates and binds the substrate and by having narrowly ellipsoid or sway-backed spores. All are initially pale yellow and become pinkish cinnamon to ochraceous cinnamon as they age. The entire upper portion of the club is covered with fertile tissue.
Distribution: Widespread in western and northern North America.
Habitat: Often these species can be found in large troops under conifers.

(Asterophora lycoperdoides)
(Asterophora parasitica)
Description: Both Asterophora lycoperdoides and A. parasitica infect russulas and lacteriuses. The fruitbodies are relatively small, with a cap and stipe, either with distinct gills or thick, distant, and reduced ones. While both species are capable of producing basidiospores, they are noted for their production of asexual spores (chlamydospores). A. parasitica has a more conic, whitish, brownish, grayish or faintly lilac cap that forms large, smooth, elliptical chlamydospores on the gills.
Habitat: Woodlands
Substrate: Old fungal fruitbodies of russulas and lacterius
(Hypomyces lactifluorum)
Distribution: Broad Broad
Substrate: Hypomyces lactifluorum, the lobster mushroom, grows in the tissue of certain russulas and lactariuses in the PNW, especially R. brevipes, and turns the host mushroom into a dense mass of mummified tissue.
(Porodaedalea gilbertsonii)
Distribution: Western North America
Habitat: Coniferous forests with Pseudotsuga menziesii.
Substrate: Wood
(Chroogomphus tomentosus)
Description: Chroogomphus tomentosus is unusual for this group in being dry and somewhat fibrillose-wooly, rather than viscid, which makes it easy to identify once the spore color and decurrent gills have been noted. It is ochraceous orange when young, at which point it could possibly be mistaken for a golden chanterelle, and later may develop wine-reddish or purplish colors. Although it often is said that chroogomphuses associate only with pines, that is not true for C. tomentosus, as it often is found in mixed conifer forests that lack pines. It apparently occurs only in western North America.
Distribution: Occurs only in western North America.
Habitat: Often is found in mixed conifer forests that lack pines.
