Just a quick follow-up on this, about two months since my initial diagnosis: After taking the oral ketoconazole for two weeks, and some prescription-strength selenium sulfide lotion every other day for the same two weeks, and since then using a cheap Walgreens knock-off of Selsun Blue with 1% selenium sulfide as a body wash about once a week, I have had no sign of the tinea versicolor.
Still unknown if the onset had anything to do with frequent diving, or whether that was just a coincidence. I'll probably never know.
