A printable chart to make a spore print and start identification. The 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 colour of the mushroom spores if viewed en masse. [1]
This mushroom can range from lilac to purple-pink. Some North American specimens are duller and tend toward tan, but usually have purplish tones on the stem and gills. Younger specimens are lighter with more convex caps, while mature specimens have a darker color and flatter cap, ranging from 4–15 cm ( 1 + 5 ⁄ 8 – 5 + 7 ⁄ 8 in) in ...
A spore print of P. stipticus, made by depositing a large number of spores in a small area, reveals their color to be white. [21] Viewed with a microscope, the spores are smooth-walled, elliptical to nearly allantoid (sausage-shaped), with dimensions of 3–6 by 2–3 μm.
Some gilled mushrooms in the order Agaricales have the ability to release billions of spores. [1] The puffball fungus Calvatia gigantea has been calculated to produce about five trillion basidiospores. [2] Most basidiospores are forcibly discharged, and are thus considered ballistospores. [3] These spores serve as the main air dispersal units ...
The color of the powdery print, called a spore print, is useful in both classifying and identifying mushrooms. Spore print colors include white (most common), brown, black, purple-brown, pink, yellow, and creamy, but almost never blue, green, or red. [7] Morphological characteristics of the caps of mushrooms
The spore print is dark violaceous brown. The spores are 8.2–13.5 x 6 – 7.1–7.7 x 5.5–6.6 μm, subrhomboid in face view, subellipsoid in side view, with a hilar appendage visible and a truncate apex with a broad germ pore, thick walled, and dingy yellow brown.
The spore print is brown. [13] The spines are slender, cylindrical and tapering , less than 5 mm (1 ⁄ 4 in) long, and become shorter closer to the cap edge. They are crowded together, with typically between three and five teeth per square millimeter. [2] Pinkish white initially, they age to a grayish brown. [6]
The spores are 8–10 by 4–5 μm, roughly ellipsoid, and only weakly amyloid. The basidia (spore-bearing cells) four-spored (occasionally two- or three-spored). The pleurocystidia ( cystidia on the face of a gill) are rare to scattered or sometimes quite abundant, narrowly to broadly ventricose , measuring 36–54 by 8–13 μm.
