Pronunciation: [sɪstˈɪdi͡ə] (IPA) 
Cystidia is a term used in mycology to describe specialized structures found on fungi. The spelling of this word can be a bit tricky, as it contains some unusual sounds. The first syllable is pronounced /sɪs/ (with a short "i" sound), followed by /tɪ/ (with a short "i" sound) and /diə/ (with a schwa sound in the middle). The final syllable is pronounced /ə/ (with a schwa sound). Overall, the pronunciation of cystidia is /ˌsɪsˈtɪdiə/.
Cystidia, in the field of mycology, refers to certain specialized cells or structures found on the surface of mushrooms or other fungi. These structures are typically elongated, protruding cells that can be observed under a microscope. Cystidia play a crucial role in the identification and classification of various fungi species.
Cystidia can vary greatly in shape, size, and presence across different fungal species. They are often found on the gills, pores, or spore-bearing surface of fungi, and their characteristics can provide valuable information for distinguishing related species. For example, they can exhibit various shapes such as club-shaped, bottle-shaped, capitate, or hair-like, and can have distinct features such as apical appendages, colored contents, or thickened walls.
One of the functions of cystidia is believed to be related to the defense mechanisms of fungi. Some cystidia are equipped with defensive structures, such as spines or crystals, which help to protect the mushroom from predators or adverse environmental conditions.
Cystidia also play a role in the dispersal of fungal spores. Some cystidia have openings or apical constrictions, acting as channels or ejection mechanisms for spore release. This allows for the controlled dispersion of spores, increasing the chances of fungal reproduction. Cystidia can also assist in the adherence of spores to surfaces, aiding in their dispersal by attaching to insects, animals, or other objects.
In conclusion, cystidia are specialized structures found on the surfaces of mushrooms and other fungi that serve important functions in taxonomy, defense, and spore dispersal. Their diverse forms and features make them valuable tools for mycologists to identify and classify various fungal species.
In bot., sacs containing spores; a kind of fructification in fungi.

The word "cystidia" derives from the Greek roots "kýstis", meaning "bladder" or "cyst", and the suffix "-idium" or "-idia", denoting a diminutive or small form. In mycology, "cystidia" refers to specialized cells found on the surface of mushrooms or fungi, which are involved in their identification and classification. These cells often have distinct shapes and sizes and play a role in spore dispersal and the overall structure of the fungus.
