Do you want to learn how to find and identify edible wild mushrooms?

Learning about edible mushrooms can seem like an overwhelming process, but don’t get discouraged. Let’s take it a step at a time.

Introductions to some common edible wild mushrooms

As mentioned before, there is a great diversity of mushroom species. Given limited space and time, we will only cover some of the most common and best to know here in this article.

For starters, mushrooms are the reproductive bodies or “fruits” a fungus. The main body of the fungus is in the form of white, thread-like structures called mycelium.

The structures of a typical gilled mushroom consist of a cap, gills and a stalk. The gills are the reproductive portions of the mushroom, and the produce the spores. Spores are reproductive units in the form of single cells.

Boletus

One of the most common and well-known groups of edible wild mushrooms are the boletes or boletus species (Boletaceae). These mushrooms have fleshy caps, and central stalk, and the reproductive parts underneath the cap are made of tubes. These tubes open up into pores at the bottom.

Many species in this group are edible, with only a handful being poisonous. The poisonous boletus species have red or deep orange pores. Outside of the few toxic species, some species of boletus are bitter or inedible.

One method for testing the edibility of a boletus species is the taste test. You can break off a tiny piece of the cap and putting it in your mouth. It is still strongly recommend that you identify all boletus mushrooms as close to the exact species as possible before trying them. This technique is not recommend for testing the edibility of any other group of species.
