Epicoccum nigrum sensitive to essential oils from plants such as lavender and rosemary. This is important in terms of the preservation of artifacts in humid climates, where fungal growth is an important determinant in the deterioration of stone structures and wood frames. "Epicoccum nigrum" produces the glycoprotein allergen Epi p 1 which binds to IgE, sometimes cross-reacting with other fungal allergens. Cross-reactivity was found to exist with "Alternaria alternata", "Curvularia lunata", "Cladosporium herbarum", and "Penicillium citrinum". "Epicoccum nigrum" is associated with respiratory fungal allergies, including allergic asthma, rhinitis, hypersensitivity pneumonitis, and allergic fungal sinusitis.
