A modest assemblage of lost cloudforms:
Tortugatrix: turtle-shaped clouds, domed and with dragging feet terminating in a point, and a scaled appearance thereof.
Dielucent: tenuous cloud-like phenomena in the upper atmosphere that gleam in the daytime, a scattering of ice crystals visible only at astronomical noon.
Altoirids: middling entities that cast reflections of rainbows into the observer’s eye.
Lemniscate nacreous: stationary clouds formed in the direction of the wind, shaped like infinite figure eights.
Microsternutus: small formations that issue from the nostrils after a sneeze.
Cumulopedia: large cloud-forms comprised of parts that can be added, edited, or manipulated by users.
Phaetonimbus: clouds that carry the sun in its procession across the zenith.
Chrysochlorulus: clouds at sunset that take on a green-gold hue.
Nubulars: long, round, narrow clouds that revolve slowly to conclusion like surf breakers.
