Lycoperdon nigrescens   (Dusky Puffball)
Family
Lycoperdaceae
Location
North America, Europe
Dimensions
1-4 cm diameter * 1.5-3 cm tall
Edibility
Inedible

Description
This smallish, dark brown, spiny, rounded structure has a short pedistal; it typically grows in troops on acid soil on heaths and in coniferous and mixed woods.

Fruiting body is pallid brown covered with dark brown spines. They are fused in groups at the tips, falling away to reveal a brown papery surface decorated with a faint net pattern. Through a sub-spherical opening through a pore at the apex, the fertile head tapers or pinches down into a distinct, but very short, sterile, spongy basal region. Spore mass is at first white and firm becoming brown and powdery. Spores are brown.

Mycena galericulata   (Common Tufted Mycena)
Family
Thricholomataceae
Location
North America, Europe
Dimensions
Cap 2-8 cm diameter, stem 5-10 cm tall * 0.2-0.4 cm thick
Edibility
Inedible

Description
This small or medium, grayish brown agaric has a bell-shaped, radially grooved cap and pinkish gills; it grows in clusters on stumps and woods, favoring broad-leaf trees, particularly oak, but also conifer stumps.

Cap roughly conical when young, becomes broadly bell-shaped or with a broad umbo. The margin is initially somewhat curved inward, but soon evens out or even becomes uplifted, and often splits radially in age. The color is somewhat buff-brown on the margin, and fades gradually to pale dirty tan to dirty cinnamon-brown. The flesh is thick in the center of the cap and tapers evenly to the margin, and is watery gray. Gills narrowly attached (adnexed) to broadly attached or sinuate. The gill spacing ranges from close to somewhat distantly spaced, with 26–36 gills reaching the stem; there are additionally three or four tiers of lamellulae (short gills that do not extend completely from the cap margin to the stem). Spores are pale cream colored. Stem is similarly colored as the cap but more pallid near the apex. It is smooth, slender, more or less equal, and somewhat rooting. It has white hair. The mushroom has no ring.
