In the RUSSULALES there are not only the many gilled Russula and Lacyarius species, but there are also crusts, toothed fungi, stereums, hypogeous fungi, coral fungi and polypores.

All of these have in common with russulas and lactarius - amyloid spores - turn blue in Meltzer’s reagent, which is mostly iodine. 002-001
