Pileal trama made up of 6–12 µm wide filamentous …when tested with Melzer's reagent turned a copper green against a white background. Is copper green a blue or a green, and is the reaction to be considered an "amyloid" reaction? In what may be another species we have found basidiocarps on which a white peridium gave a grass-green reaction ~ith Melzer's sol.A total of 1986 AMF viable spores were extracted from all evaluated soil layers. Spore abundance was significantly higher in the superficial layers (0–20 cm, 20–50 cm and 50–100 cm), with numerical variations of 128–159, 110–141 and 80–106 spores in 50 g soil −1 respectively and decreasing at deeper layers with variations of 7–23 spores 50 g soil …Rolf Singer sometimes invokes a "slightly amyloid" reaction, where the fungal tissue turns yellow or pale brown. One most commonly checks white spores to see if they are amyloid, but context gets checked fairly regularly also. The iodine solution of choice is Melzer's solution (or sometimes Melzer's reagent ), a combination of iodine with ...T. dendroidea (see Fig. 2) and T. chamissonis.

Melzer's reagent is an aqueous solution of chloral hydrate, potassium iodide, and iodine. Depending on the formulation, it consists of approximately 2.50-3.75% potassium iodide and 0.75–1.25% iodine, with the remainer of the solution being 50% water and 50% chloral hydrate. Melzer's is toxic to humans if ingested due to the presence of iodine ...

Melzer's reagent. Chloral hydrate is an ingredient used to make Melzer's reagent, an aqueous solution that is used to identify certain species of fungi. The other ingredients are potassium iodide, and iodine. Whether tissue or spores react to this reagent is vital for the correct identification of some mushrooms. Safety

These observations suggested that this wall was composed of quaternary ammonium compounds and polysaccharides with few exposed α-1,4 linkages.

Spores of Acaulospora “honey comb” are 90-100 µm diameter, spore wall is ornamented with circular reticulum with a smooth center and two bilayered germinal walls (gw) are present, the innermost layer of gw2 turning light pink to reddish in Melzer′s reagent.
