Species Information

Summary:
Features include 1) pear-shaped or top-shaped whitish fruitbody, with slender, short, cone-shaped warts interspersed with smaller spines or granules, these warts falling off leaving scars in a mesh-like pattern at first, the spines white to gray, 2) the inner layer rupturing through a round hole at the top, 3) the spore mass firm and white at first, becoming soft and turning yellow, then olive, and finally darker brown and powdery, 4) the stem conic and about two thirds of the total height, the sterile base well developed with large chambers, 5) growth on the ground in a variety of habitats, and 6) round, minutely spiny spores. Lycoperdon perlatum is the commonest puffball in the Pacific Northwest and probably in North America. New York Botanical Garden has collections from BC, WA, OR, ID, AB, NF, ON, PQ, AK, AL, AZ, CA, CO, CT, DC, FL, GA, HI, IA, IN, KS, MA, ME, MT, NC, ND, NE, NH, NJ, NM, NY, OH, PA, TN, VA, WI, WY, Jamaica, Panama, Brazil, Colombia, Austria, Belgium, Czech Republic, France, Germany, Switzerland, United Kingdom, South Africa, China, Japan, Australia, and New Zealand, (NYBG). It is also found in YT (Schalkwijk-Barendsen), and is reported from IL, KY, LA, MD, MI, MN, MO, OK, SC, TX, UT, VT, and WV, and India, (Bates).
Outer Surface:
1.5-6(9)cm across, 3-7(10)cm high, pear-shaped or top-shaped or nearly spherical "with narrowed often wrinkled stem-like base"; outer layer "of slender, short, cone-shaped spines interspersed with smaller spines or granules, the larger ones leaving scars"
Inner layer:
at first with scars, but often smooth when old, white to tan becoming yellowish brown to grayish brown or dark brown when old; rupturing through a pore at top, (Arora), membranous, tough, reticulate [net-like] pattern after warts fall off, rupturing to fo
Spore Mass:
firm and white at first, "soon becoming soft and turning yellow, then olive", and finally becoming dark olive-brown to chocolate brown or brown and powdery, (Arora), "white when young, then olive to olive-brown", (Breitenbach), at first white, then ocher-
Stem:
sterile base large, well developed, with chambers, "at first white and spongy, then yellow, olive, brown, or chocolate-colored", (Arora), stem conic, about two thirds of the total height and up to 3cm wide, surface warty when young but smooth when old; sterile base inside white when young, then olive to olive-brown, larger chambered than spore-mass, (Breitenbach), sterile base with large chambers, forming a thick, often persistent stem, (McKnight)
Odor:
none (Miller)
Taste:
mild (Miller)
Microscopic:
spores 3.5-4.5 x 3.5-4.5 microns, round, minutely spiny, (Arora), spores 3.5-4.5 x 3.5-4.5 microns, round, finely verrucose, brown, rather thick-walled; basidia 2-4-spored, 7-10 x 4-5 microns, short-clavate, without basal clamp connection; capillitial threads 2.5-7 microns wide, brownish, without septa, elastic, thin-walled to thick-walled, smooth or with bumps, with occasional pores [pits], (Breitenbach), spores with no pedicel (McKnight)

Habitat / Range

single, scattered, gregarious, or clustered, "on ground in woods and under trees, along roads, or sometimes in the open", usually fruiting in fall or winter, (Arora), usually gregarious, more rarely single, on soil and needle litter in conifer or mixed forests, more rarely outside forests, summer to fall, (Breitenbach), "on ground in conifer or hardwood forests or on mulch or compost piles" (Bessette), "in woods of various kinds, also in lawns or on cultivated ground", (Ammirati)
