Common fungus stains

• PAS = stains cell wall purple

• Gomori–Grocott methenamine silver (GMS) stain = stains fungi black against a green background

• Mucicarmine or alcian blue stain capsules (i.e. Cryptococcus neoformans)

• Calcofluor white = imparts bright fluorescence to fungi under fluorescence microscopy
