A sulphurous end to the mildness of autumn

Lots of wood-rotting going on in Fox Wood Covert this afternoon, with also a few Buttercaps, Rhodocollybia butyracea, scattered around and a small patch of the Sulphur Knight, Tricholoma sulphureum, near the beginning. Note the central browning around a small remaining umbo. There are some purple shades on some caps according to the books, often quite confusing.

It is a relatively tall mushroom! Stem often twice the cap diameter, as it appears to be here. And the smell was definitely strong and noxious.

I couldn't see any reddish fibres on the stem as described and the gills looked almost decurrent within the "sinuate" range. 

Supposedly mycorrhizal with deciduous trees such as Oak and Beech, only occasionally with conifers. These ones might be linked to some nearby Oaks, oddly I haven't found it under the Beech trees elsewhere in the woods.

Compare to Tricholoma frondosae under Aspen at Beacon Wood a couple of weeks ago.

A lovely patch of Stereum subtomentosum, both from above and below, trying to look a little like Turkeytail.

This Datronia mollis was I think on a long-fallen Ash branch, stacked by kids on a Hornbeam. This is quite variable according to age and development. I suspect the first two are images of the same younger patch of fruiting body, the first untouched and the second rubbed.  The third image is I believe an older and more bruised patch, with proportionately larger pores, but still resupinate and not yet elongated and maze-like. 

In the last photo there is a jelly-like species, just possibly Crystal Brain, Exidia nucleata.

This appears to be a very young King Alfred's Cakes, Daldinia concentrica, which ought to be a mid-brown colour in itself, but covered in greyish spores. 

and this is the context. There looks to be some Chlorociboria on the log below, presumably Oak.

There was a nice patch of Candlesnuff, Xylaria hypoxylon on a mossy log

This appears to be a Bonnet or Mycena species pretending to be an Oysterling or Crepidotus. Shows how to fool the AI! 

The Peeled Oysterling, Crepidotus mollis, seems to be having a good year.

 A nice Ganoderma adspersum on one of the boundary Hornbeams,

There was one log with fruiting Smokey Bracket, resupinate and reflexed, Bjerkandera adusta, possibly on Hornbeam.

Finally a variety of fresh growths, again resupinate and reflexed, of the Silverleaf Fungus, Chondrostereum purpureum, possibly on Hornbeam
