MUSHROOM SPORE PRINTS
The Mushroom Spore Print is the powdery deposit obtained by allowing spores of a fungal fruit body to fall onto a surface underneath. It is an important diagnostic character in most handbooks for identifying mushrooms. It shows the color of the mushroom spores if Mushroom Spore Pintsviewed en masse
IMPORTANCE OF MUSHROOM SPORE PRINTS
Historically the classification of many families of Fungi were based on spore colour, a feature first systematically emphasized by Swedish mycologist Elias Fries. An example is the Tricholomataceae, a large family containing many fungi whose common factor was having white spores. However recent molecular research has shown some strange relationships, with some fungi of disparate spore colours showing close relations.
A spore print is made by placing the spore-producing surface flat on a sheet of dark and white paper or on a sheet of clear, stiff plastic, which facilitates moving the spore print to a darker or lighter surface for improved contrast; for example, it is easier to determine whether the spore print is pure white or, rather, very slightly pigmented. The mushroom is left for several hours, often overnight, in this manner. Some guides advise using a moisture-resistant enclosure, like a glass or jar, to contain the mushroom during printing. If the mushroom is to be preserved, a small hole can be made in the mushroom spore print paper rather than cutting the stipe.
When the mushroom is removed, the colour of the spores should be visible. We often use glass slides, which allow for quick examination of spores under a microscope. A mushroom cannot be identified from its spore print alone; the spore print is only one characteristic used in making a taxonomic determination. Spore prints are usually white to cream, black, or shades of red, purple, or brown. The poisonous false parasol (Chlorophyllum molybdites) has a green spore deposit.
Although the spore print is generally used to help identify the genus of a specimen, on occasion it can be used to help distinguish between similar species. For example, the lookalikes Russula crustosa and Russula virescens have yellowish and white spore deposits, respectively.https://thepsychedelicnow.com/
