Shaggy Fungus

As I was heading off to work this morning, I noticed this fungus emerging from a nature strip. This one was about 20cm tall, and there were a couple of smaller ones about 3 metres away, presumably part of the same organism.

It's not in my book of Australian fungi, but the internet tells me it is probably an introduced species, Shaggy Mane (Coprinus comatus). Even though it's not a native, it appeared on an Australian stamp in 1981.
