Candida

Candida is a genus of yeasts.

In Latin candidus, candida means clear and white, with the whiteness of pure quartz rather than the whiteness of chalk (albus).

Candida was the name of the clear-thinking, outspoken and candid eponymous heroine of Shaw's 1895 play poking fun at well-meaning socialist reformers in the Church of England.

Candida was also the name of a 1970 song performed by Tony Orlando and Dawn.
