blue mould

Through the negligence of the servant they have been hung up in a damp state, and had become covered with blue mould.

They kept him in a dark place, like a cheese, until he had the full Tellson flavour and blue-mould upon him.

The chief condition in the existence of the blue mould is excessive moisture.

When ripe it is permeated by a blue mould, and resembles in flavour, appearance and consistency a rich old Stilton.

One is half inclined to look for a coating of blue mould over the streets and houses.
