Database disappeared from PhpMyAdmin

Question

I'm a relative newbie, so please bear with me... I created a typical wordpress database in PhPMyAdmin via MAMP (on Mac OSX 10.8). I built up the site a bit, and yesterday evening I pulled up PhPMyAdmin and the database had completely disappeared. Now there's just "information_schema", "mysql", "performance_schema", and an older wordpress database.

Though different users were created in PhPMyAdmin, I don't think this is a privledges issue b/c I'm logged in as root.

How, if possible, might I recover the database? More importantly, can anyone give me insight into why the one database would completely disappear without a trace?

Let me know if I can further clarify. Thanks in advance for your advice.
