Nineteenth century. Appellativization from genus name Mycoderma, which was coined in 1822 as a scientific name for the putative genus of organisms in mother of vinegar; they were named thus under the belief that they were fungi (although in fermentation there may also be bacteria present besides the yeast), hence the combining form myco- (for more, see Wikipedia); by surface analysis, myco- + derma, where the latter component refers to the "skin" formed on fermenting liquid.
Nineteenth century or earlier. By surface analysis, myco- + derma, where myco- is an antiquated alternative spelling of muco- explained by the usual transliteration possibilities (y or u) for υ (u), Greek upsilon; as explained at mucus (English) from mucus (Latin), Ancient Greek words for mucus and mushrooms and sliminess were related.
