ID help Black mushroom

Please try to include photos to show all parts of the fungus, eg top, stem, and gills.
Note any smells, and associated trees or plants (eg oak, birch). A spore print can be very useful.

Hello and welcome to UK Fungi
Do have a look at this thread: viewtopic.php?f=4&t=49.

Yes, apps and books can often only take you so far. One thing is they tend to feature photogenic species at their optimum appearance. You have a couple of rather old examples.

Not a genus I deal with much, but your blackening one is very distinctive: Russula nigricans. The distinctive features are:
  • the blackening, generally proceeding from its original dull white, through reddish to this "burnt" stage.
    the rather widely spaced gills (for a Russula)
    the thick gills (for a Russula)
    the presence of intermediate gills which don't reach the stem. Most Russula species do not show this character.
The brown one is too far gone in my opinion, I have a couple of thoughts, but not being able to see the gills or more of the stems I wouldn't want to comment. Which takes us back to that thread (link above).

Hi and welcome to UK Fungi,

I agree with what Chris has said.

My initial suspicion was that the brown ones may be one of the Honey Fungus Species - but they do look quite small, so Chris is obviously right not to comment as they may well be another species altogether.

Interestingly, the third image appears to show one of the "Piggyback" fungi species (Looks like Silky Piggyback - Asterophora parasitica from what I can make out), attacking the cap of the Russula nigricans. (Two or three small white mushrooms visible on the blackened cap of the Russula).

Common sense is not so common.

The third photo also seems to be showing the start of Asterophora parasitica a small fungi that grows on the rotting fruitbodies of Russula especially R nigricans.
Ps I would guess Hypholoma fasciculare for the brown ones
