Melzers reagent - In middle aged spores, it may or may not expand slightly, but it usually reacts with Melzer's reagent (in PVLG-M) to become pink or red. In what seem to be fully mature spores, this component remains evident, but does not always react to Melzer's reagent. In very old spores, this component disappears, hence its designation as evanescent.

 
It's because chloral hydrate is a controlled substance. If you can get it somewhere you can mix it yourself. Formula. Otherwise check if your local mushroom club has a way of obtaining it. You can order it from Germany but the shipping costs will be pretty high. Best to order quite a bit and split the costs with other mycologists.. Racism explanation brainly
