Given the above summary, write a detailed text in English for it.
Search for Porcinis near spruces, firs, and pines. They are typically ready to harvest in early fall at lower elevations and summer at higher elevations. They tend to have thick bulbous stems near the ground that get thinner towards the cap. Look for a yellow to golden-yellow colored mushroom with wavy, upturned edges. The stalk is shaped like a trumpet and thickens where it joins the cap. Chanterelles are often found under hardwood trees and conifers in the fall to early spring time. Keep an eye out for the puffball’s unique, densely packed spines on the cap, which brush off easily. Puffballs tend to grow along trails and woodland edges in the fall and winter. Cut puffballs in half to check that they are good to eat. They should be pure white inside. If they are yellow or brown inside, they are no longer edible. Look for numerous, blade-like gills that hang down tightly over a hollow stalk. These mushrooms grow well in urban areas in cool, wet weather. Avoid picking Shag mushrooms near busy roads, as they may be contaminated with car exhaust.
