Since many orchids retain their leaves for several years, foliage is bound to develop markings and spots as the leaf ages. On the other hand, high humidity and overly moist soils can encourage fungal diseases. If the spots enlarge or you find them on other leaves you may want to use a fungicide on your orchid. Any houseplant fungicide such as Banrot will help control fungal diseases.
