Fungi popping up everywhere

There seem to be toadstools popping up everywhere at the moment - in the lawn, in the flowerbeds and in the woods.  Andy M has taken a few pictures, and hazarded a guess at identifying some of them - suggestions welcome !

Sprouting en masse from an old tree stump on Granta Park. 

Cap about 1cm across.  (Coprinus disseninatus)

Growing in the lawn at home - cap about 3-4cm across. 

Gills white and well spaced. Stipe streaked pink. (Hebeloma spp?)

Hard and scaly, eventually splitting to release black spore-mass inside.

Growing in the soil, about 4-5cm across. Common Earthball (Scleroderma aurantium)

Crazed, reddish-brown cap and red stipe, about 7-8cm across, with characteristic 

tube-shaped 'gills'. Growing on woodland edge at home. (Boletus pulverulentus)

Large fleshy cap with brownish scales and splitting edges 

- around 12cm across. Pinkish-white gills and chunky white stipe. 

In the mown grass on Granta Park.  (???)
