Aphthae, a name applied to the small white patches which are sometimes seen on the tongue, lips, and cheeks, and which are now known to be due to the growth of a fungus, the Oidium albicans. Aphthae are not uncommon in suckling children. In adults they are rarely seen, and only in conditions of extreme exhaustion produced by such diseases as typhoid fever or consumption.
