Add spores, keeping water to a minimum if using pipette. Let stand for at least 5 minutes to let surface of drop dry slightly (increasing viscosity of edges, reducing flow when coverslip is added).

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.
