Melzers reagent

To make diagnostic slides with fungi freely occurring on the surface of different plant parts or growing in agar cultures, their sporophores with spores and mycelium were collected by means of the end of a needle and placed in a drop of water, lactic acid, polyvinyl alcohol/lactic acid/glycerol (PVLG; Koske and Tessier 1983), or a mixture of PVLG and ….

Melzer's reagent can be used to test whether spores are amyloid, nonamyloid, or dextrinoid . Spores that stain bluish-gray to bluish-black are amyloid. Spores that stain brown to reddish-brown are dextrinoid. This test is normally performed on white spored mushrooms. One at the top right showing the reaction under treatment of Melzers reagent. D.
