Here are some others with almost perfect lenticular shapes:
The one I've posted in my first post here is not a lenticular cloud, but rather an iridescent pileus cloud, also called a cap cloud.
These smooth, round clouds form on top of a puffy cumulus cloud when it rises into higher, colder air.
The pileus cloud is made up of uniformly sized water droplets that diffract sunlight, creating a rainbow of colors. Usually, the effect is outshone by
the brightness of the sun, but in some photos, the darker cloud is helpfully blocking the glare to reveal the spectrum of light behind.
