Wild mushrooms, alternatively known as toadstools, are the fruiting bodies of a type of fungus. They act as a food source to both humans and animals alike. They are typically found on the ground or near/on trees. Being wild, some are poisonous, so caution must be exercised whilst dealing with them.
In order to distinguish between the different variations, one needs to have an elementary knowledge of their macroscopic anatomies. The majority of mushrooms are referred to as gilled and Basidiomycetes. The basidiospores are first shot off the basidia and fall in-between the gills afterwards. Because of this, if you cut the cap off and leave it gill-side-down throughout the night, a powdery indentation is created, one in the shape of the gills.
The powdery depression's colour is what we use to both classify and discern them. Shades include creamy, purple-brown, black, yellow, white, which is the most common of all, and pink. Red, blue, and green prints are almost never encountered. This is a fantastic substitute for smelling and tasting mushrooms, because the allergens and poisons present can cause more than a few problems.
There are plenty of establishments out there you can call if you want help with any queries about wild mushrooms. Just remember to let them know of your specifications.
