Historical definition

Citrinulus is pale crystal.

Meaning

The definition gives a material class and a colour-like qualification. It supplies no locality, growth form or modern mineral species. “Pale” should remain the descriptive limit rather than being expanded into a precise hue without evidence.

The spelling distinguishes the entry from Citrinulum, the transparent salt made from calcined vitriol, and Citrinula, the blistering herb. The three names are worth linking precisely because their meanings diverge. A finding aid should help the reader choose the correct word rather than combine them into a single family of substances.
