Pileus caps are made of ice crystals high in the troposphere. They form as a slab of air is shoved upward, in the shape of a dome or cap, just above a rapidly rising convective tower. Moisture in the dome condenses directly into an ice fog as the air rises and cools, forming the pileus.

Weather photography by Bernard Hulshof ... The pileus layer forms when a convective cloud pushes a moist layer of air above it upwards, causing condensation in this layer. Often these pileus clouds are shortlived, as the strongly rising convective cloud will eventually pierce thru the pileus layer.

The lifted air that produces pileus clouds is typically drier than the moist air from lower levels often responsible for cumulus clouds. There is little tendency for any significant vertical growth in pileus clouds, which is why they take on a smoother, horizontal shape.
