A kind of skull cap of felt.
The expanded upper portion of many of the fungi. See Mushroom.
An accessory cloud of small horizontal extent, often cirriform, in the form of a cap, hood, or scarf, which occurs above or attached to the top of a cumuliform cloud that often pierces it. Several pileus clouds fairly often are observed above each other. Pileus occurs principally with cumulus and cumulonimbus.
a cap as in a mushroom cap
A close fitting cap of felt or leather or wool, similar to skullcap. Common to Ancient people. During the Renaissance, the cap evolved into BIRETTA.
n. (L. pileus, cap) umbrella-shaped structure of mushrooms or toadstools.

Latin - cap A cloud in the form of a cap above or attached to the upper part of a cumuliform cloud, indicating strong updrafts within the cloud.
a conical cap, in Greek art worn by Odysseus, Hephaistos and the Dioscouroi. It was also traditionally given to freed Roman slaves and thus became a Roman symbol of liberty.
The expanded caplike portion of some basidiocarps or ascocarps that supports the hymenium. (Pl. pilei.) ( 15)
cap especially in Agarics
A pileus (Latin for cap) is a small, horizontal cloud that can appear above a cumulus or cumulonimbus cloud, giving the parent cloud a characteristic "hoodlike" appearance. Pilei tend to change shape rapidly. They are formed by strong updrafts acting upon moist air at lower altitudes, causing the air to cool beneath its dewpoint.
The pileus is the technical name for what is commonly known as the "cap" of a fungal fruiting body. It is particularly characteristic of agarics, boletes, and some polypores, tooth fungi, and ascocarps. Other sporocarp types have less clear differentiation between the pileus and the rest of the fruiting body.
