The mystery donor who has been making anonymous gifts of $1-million to $10-million to colleges run by women may have given as much as $90-million, the Philadelphia Inquirer reports.

At least 18 institutions now report receiving donations, with Temple University now announcing that it received a donation in January 2008, the newspaper says.

The donor has requested that the universities use the money for scholarships and to cover general expenses, and requires that institutions do nothing to investigate where the money came from.
