Seem to be able to grow just about anywhere, even directly out of stone or brick walls, so long as they can get enough moisture.
The example above was growing from a dead bough of a rose bush, the one below on a stone bird bath.
Before it begins to fade, this toadstool is coloured a peculiar shade of green.
The specimen above was already beginning to get washed out and faded. Somewhat nearer the original shade is this one hiding in the grass.
And someone had helpfully kicked this one over, giving a clear view of the stem and the gills.
Milkcaps are a group of toadstool species which produce a fluid when the cap is injured in any way. In some species, such as this, the fluid is white, and looks very like milk.
I had just lightly brushed this specimen while clearing away a bit of debris to get a clearer view. The result: a copious amount of “milk”.
