Composition. 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 ...I have found that both a cross-sectional Roman aqueduct section and a radial cap section that includes the center of the cap are usually required, both mounted in KOH—along with a third slide of mature gill tissue (or a spore print scraping) mounted in Melzer's reagent. In other words, studying lepiotoid mushrooms under the microscope means a ...The sequestrate genus Melanogaster is rich in mainland China. A total of ten taxa are supported by molecular evidence in this study, including five known species, four new species, and one putatively new species (supported by an ITS sequence from ectomycorrhizal root tip). Based on our morphological reexamination of the type or authentic specimens, four species recorded in China, including M ...
