Yellow staining agarics are quite common: these pictures are from several different locations which I passed while strolling around Wolverhampton in the first half of the month. They could easily be confused with common field mushrooms, the wild form of ordinary supermarket mushrooms.

But these aren’t good to eat, guaranteeing an upset stomach. The giveaway is the yellow staining – a discolouration of the damaged flesh when the mushrooms are bruised or broken.

Growing from a thin layer of moss on the top of a stone wall, a single tiny mushroom. It’s not the first time there’s been one there around this time of year.

Autumn is spider season, or at least the time of year when a lot of species become more visible, both around the home and outdoors. or many spider species, autumn is the mating season.

I don’t know if this little spider is one of those. It was busy rushing round its web, which was on the bridge carrying the Castlecroft road across the Railway Walk. As it moved, it cast a sharp-edged shadow in the bright sunlight.

Colourful fly agarics in the shelter of a beech hedge at Bantock Park. Underground, they are intertwined with the roots of one of the silver birches which are a few yards away.

A group of earthstars from the Tettenhall churchyard. They are one of the rarer earthstar species, and had clearly been up for some time. They were battered – some looked like they had been kicked.

Most autumns, the corner of Tettenhall Upper Green between the paddling pool and the main road has tiny mushrooms barely peeping out of the short grass. They are parrot waxcaps. Bright yellow and shiny when they first emerge, they later turn to a shade of green somewhat similar to the feathers of some parrots: in some of these specimens, that change of colour is just beginning.

It;s possible that some of these pictures are of a related species. Butter waxcaps are also bright yellow and glossy, but don’t change colour.
