 The cap
This was the pileus or birettum.(4) This cap in its turn was a shallow form of the cap of liberty presented to Roman freedmen to cover their newly-shaven heads and to mark their emancipation, the pileus(5).
The pileus rotundus had formerly been restricted to doctors in sacred theology, canon law, medicine, and civil law.(14) But when, in early Tudor times, a pileus quadratus came to be bestowed upon doctors, a pileus rotundus had begun to be worn by those of lower degree.
The pileus rotundus, perhaps the John Knox laical cap, was worn by doctors in civil law, medicine, music, etc, instead of the pileus quadratus which they had previously worn.

The fundaments of the pileus and stem at this stage stain faintly in contrast with the deep stain of the surrounding fundamental tissue.
As it is stretched by the expansion of the pileus the looser, spongy, lower portion of the veil is separated from the pileus margin and surface of the stem and torn into the scales characteristic for the species, while the firmer upper (inner) portion is later separated from the margin of the pileus.
External to the pileus primordium and the upper portion of the stem fundament is a zone of fundamental tissue with an open mesh.

 BIRETTA - LoveToKnow Article on BIRETTA   (Site not responding. Last check: 2007-10-12)
Though the form of the biretta, devised in the 17th century, is peculiar to the Roman Church, it is but a variant of the original biretum, which developed in various countries into head-coverings of different shapes and significance.
At the outset there was little to distinguish the biretum from the pileus or pileolus (skull-cap), a non-liturgical cap worn by dignitaries of the Church under the mitre and even under the biretta.
As an ecclesiastical vestment the cap can be traced, under the name of pileus, to the 12th century; under that of infula, to the end of the 10th.

 Pileus Clouds: smooth capping clouds
Pileus (Latin for "skullcap") is a smooth cloud found attached to either a mountain top or growing cumulus tower.
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.

The pileus is formed by the expansion of the stem apex, due to interstitial and divergent growth.
Perpendicular downward growth of hyphae from the under surface of the pileus, beginning in the angle between stem and pileus, forms the primordium of the hymenophore as an annular zone of new growth surrounding the stem apex.
The annular prelamellar cavity is formed by the breaking away of ground tissue left in the angle between stem and pileus after their differentiation, due to the growth and expansion of these parts.

 Artificial cultivation of Ganoderma lucidum   (Site not responding. Last check: 2007-10-12)
In the last stage of growth, spores break on the down side of the pileus and fall down to cover all the ground into reddish brown color.
For first week of this condition, it is needed to water it, and 10 days later, not to water in order to keep the spore on the pileus, because the spore has most nutrition ingredients.
There is an individual difference, but in general, harvesting is carried out 20~30 days after the discharge of spores was started at the time when the white part of the circumference of a pileus disappeared to become reddish brown and the thickness of the pileus increased to become full.

 ^Pileus ^Project
The Pileus Project, an interdisciplinary, project funded by the US Environmental Protection Agency (USEPA) to determine the potential impacts of climate change and climatic variability on agriculture in the Great Lakes Region.

This unaltered photo showing a pileus cloud was taken on June 25, 2004 from New Smyrna Beach, Florida.
As afternoon thunderstorms were quickly building, and the Sun was beginning to set, the ingredients were in place for a spectacular light show -- if the timing was exactly right.
When the Sun was in just the proper position, a pileus cloud began forming, and its shadow was cast upwards at the same time the pileus was "catching fire."
