The mushrooms produce spores that are wind dispersed, and through this method, new colonies acquire a fungal strain. [23] In some species, the genetic variation of the fungus is very low, suggesting that spores of the fungus are transmitted vertically from nest to nest, rather than from wind dispersed spores. [26]
Omphalotus olearius, [2] commonly known as the jack-o'-lantern mushroom, is a poisonous orange gilled mushroom that to an untrained eye appears similar to some chanterelles. It is notable for its bioluminescent properties. It is found in woodland areas in Europe, where it grows on decaying stumps, on buried roots or at the base of hardwood trees.
The false truffle depends on the rodents to help spread its spores as it does not have the ability to eject the spores themselves. The rodents are attracted to a scent produced by the false truffle and ingest the spores. Spores survive the intestinal tract of the rodents and are excreted in the fecal matter ready to germinate.

These are also the main factors to its pathogenicity. As the fruiting body continues to grow and obtain nutrients, it forms into a mature mushroom. Armillaria ostoyae in particular grows wide and thin sheet-like plates radiating from the stem which is known as its gills. The gills hold the spores of a mature mushroom.
Mushrooms grow well at relative humidity levels of around 95–100%, and substrate moisture levels of 50 to 75%. [1] Instead of seeds, mushrooms reproduce through spores. Spores can be contaminated with airborne microorganisms, which will interfere with mushroom growth and prevent a healthy crop.
California's annual number of infections rose from fewer than 1,000 in 2000 to more than 9,000 in 2019. According to a recent report from the state health department , there have been 5,370 ...
(The spores are what you see growing on the food.) So cutting out or around mold on foods may not get rid of it, the experts warn. In fact, slicing a knife through a moldy spot can spread the ...
