More or less permanent mounts of fungi, algae, root tips, epidermis, germinating spores, and other small objects may be made readily by transferring the material to Amann's lacto-phenol containing anilin blue, W. S. or acid fuchsin, used singly or mixed. The addition of 20 to 25% of glacial acetic acid to these mixtures is frequently advantageous; or material may be stained with various dyes—acid fuchsin, anilin blue, W. S. (cotton blue), rose bengal, phloxine, hematoxylin—in aqueous solutions containing 5% of phenol, and then mounted in lacto-phenol, 50% glycerin or phenolglycerin, depending on the dye used. The phenol solutions of acid fuchsin and anilin blue are acidified with acetic acid and those of rose bengal and phloxine are made slightly alkaline with ammonium hydroxide. The addition of ferric chloride to acid fuchsin or acidified hematoxylin may improve staining. Fixation may be preferable but may be omitted, especially with fungi. Formulae for the mounting media and ten staining mixtures are given.
