Collecting and examination of a spore print is not always successful. Some mushrooms are too young or too old to produce spores. Mushrooms collected at high elevations will typically not produce a spore print at lower elevations. [2] Sometimes, the colour can vary depending on the thickness of the spore print.
A common mushroom identification technique is the spore print, in which a mushroom is placed on a surface and spores are allowed to fall underneath. This technique is often used by mycologists and mushroom hunters distinguish identify the genus of a specimen and differentiate between similar-looking species.
For T. microcarpus, the mushrooms grow from fragments of fungus garden that are carried outside the nest by worker termites. [14] When a new termite colony is established, in most cases, the fungus is introduced through the activities of the termites collecting spores from the environment. [5]
People who collect mushrooms for consumption are known as mycophagists, [37] and the act of collecting them for such is known as mushroom hunting, or simply "mushrooming". Even edible mushrooms may produce allergic reactions in susceptible individuals, from a mild asthmatic response to severe anaphylactic shock.
The basidia are 25–40 μm long and 5–7 μm wide, contain four spores each and possess a basal clamp. The white amyloid spores measure approximately 5–7 μm in length and 4–5 μm in width. The spore shape is described as subglobose to short ellipsoid and the spore surface is smooth to finely roughened. [5] [6]
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 ...
Spore print: White. Spores: Ellipsoid to amygdaliform with a large germ pore. Dextrinoid. The average size range is 7.7-10.5 x 5.9-7.3 μm. Smell: Indistinct or sometimes mushroomy. Taste: Indistinct. [28] [29] When dry the mushroom may discolour tan or brownish and a similar brown colour is seen in caps of aborted mushroom pins which fail to grow.
Species in the genus Agaricus have a partial veil that is made of two layers of tissue, although the two layers are not clearly distinct in all species. [8] In the early 20th century, American mycologist George Francis Atkinson investigated the development of the mushroom Agaricus arvensis by collecting young mushroom buttons (immature fruit bodies with the veil intact and the cap not yet ...
