Depending on the formulation, it consists of approximately 2.50-3.75% potassium iodide and 0.75-1.25% iodine, with the remainder of the solution being 50% water and 50% chloral hydrate. [2] [3] Melzer's is toxic to humans if ingested due to the presence ...Melzer's reagent was used to test for the amyloid reaction. Asexual structures were observed microscopically in water or 5 % KOH. The descriptions of the sexual state and branching pattern of conidiogenous structures were classified according to Ju and Rogers ( 1996 ).Melzer's reagent is an iodine solution producing a blue-black "amyloid" reaction in some spores and parts of fungi. However, Melzer's reagent contains chloral hydrate, a medically...

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.Multiple apothecia are located on the branches, mostly toward the tips, and are composed of 8-spored asci and paraphyses embedded in a gelatinous matrix that turns blue in Melzer's reagent.At least 50-100 spores of each species were mounted in water, lactic acid, polyvinyl alcohol/lactic acid/glycerol (PVLG, Omar et al. 1979), and a mixture of PVLG and Melzer's reagent (1:1, v/v) and examined to determine the morphological features and the phenotypic and histochemical characters of their spore wall layers.
