Abstract
Spore marking material of selected operculate discomycetes has been examined histochemically using aniline blue and hydroxylamine-ferric chloride, tests specific for callose and pectins respectively. Contrary to earlier reports based on nonspecific stains, the marking substance is apparently neither callose nor pectin. Solubility tests also indicate that callose is not present.
