What is "brollies"

Usage examples of "brollies".

There were windows looking out on a night view of fog-fuzzed city lights, a cracked leather settee and two old frieze armchairs, a coffee table rather the worse for wear, an antique computer on a kneehole desk, shelves of plaques and paged books —even a ceramic umbrella stand holding two decrepit black brollies, a blackthorn cromach, and a bent toasting fork.

I imagine I thought it was going to be like one of those sitcom depictions of suburbia, with all the identical front doors opening at precisely the same time, and identically dressed men marching down the street together, clutching identical briefcases, brollies and newspapers.
