Amyloid ornamentation of Lactarius basidiospores. Mushroom identification relies on many tricks of the trade. One of the fun tricks is treating white mushroom spores with iodine in the form of Melzers Reagent to see if they turn bluish-black (much as iodine will turn the inside of potatoes bluish-black). The term for this reaction is amyloidity.Spore observations should be made in a Melzer's reagent mount to assess whether the spores are amyloid or not. While most mycenoid species have amyloid spores, they are not as strikingly amyloid as, for example, the amyloid spores of some Amanita species--and the amyloidity usually fades as the spores age and mature, so that many spores in a ...Language links are at the top of the page across from the title.Melzer's reagent (also known as Melzer's solution or informally as Melzer's) is a chemical reagent used by mycologists to assist with the identification of fungi.
