What is a type of fungus that affects plants or grows on inanimate objects?

Mildew is a type of fungus that typically appears as a thin, coating or powdery substance and is commonly found on plants, fabrics, and other surfaces where there is moisture. It thrives in warm, humid environments, which is why it's frequently encountered in gardens and areas with poor ventilation.

Mildew can damage plants by contributing to decay and inhibiting growth, making it a concern in both agricultural and ornamental horticulture. The characteristic flat appearance of mildew sets it apart from other types of fungi.

While yeast and mold also fall under the broader classification of fungi, they have different characteristics and growth patterns. Yeast is primarily unicellular and is typically involved in fermentation processes, while mold encompasses a wide variety of fungi that grow in filamentous structures and can include numerous species that affect food and organic materials. Recognizing mildew is important for effective management in plant care and maintaining cleanliness in various environments.
