Word History

Etymology

borrowed from New Latin, from myc- (from base of Greek mykēt-, mýkēs "mushroom, fungus") + -el- (of unknown origin) + -ium -ium — more at myco-

Note: Term introduced by the Austrian botanist and mycologist Leopold Trattinnick (1764-1849) in Fungi Austriaci, ad specimina viva cera expressi descriptiones ac historiam naturalem completam addidit Leopoldus Trattinnick/Oesterreichs Schwämme, nach lebendigen Originalen in Wachs gearbeitet mit Beschreibungen und einer ausführlichen Naturgeschichte, 1. Lieferung (Vienna, 1804). Trattinnick, who uses the word throughout the work, gives no indication of its derivation. His translation in the parallel vernacular columns is Schwammgewächs, literally, "mushroom growth." The reading of -el- as Greek hêlos "nail head, wart, callus," apparently first proposed in the Century Dictionary and copied by many dictionaries since, is improbable and in any case purely speculative. Somewhat more probable is the suggestion in the Oxford English Dictionary that the interposed -l- is after epithelium.
