Jesmond Dene- September Fungi

September is a good time to look for fungi appearing in the autumn. Fungi are in their own Kingdom and difficult to identify accurately. The familiar fruiting bodies known as toadstool or mushroom are the ephemeral visible parts of an underground network called a mycelium.

Red cracking Bolete (Boletus chrysenteron) has a reddish appearance under the cracks.
Probably Cep or Penny bun (Boletus edulis) since the flesh does not discolour.
Unlike the dark staining on this species. Most likely Bitter Bolete (Boletus calopus) often found under beech.
Horse Mushroom (Agaricus arvense) is fairly common.
The blusher (Amanita rubescens) is also common and edible.
as is Shaggy Parasol (Chlorophyllum rhacodes)
Russula are difficult to name to species level.
One of the Honey Fungi (Armillaria mellea) freshly emerging showing a yellow ring.
More mature honey fungus.
The familiar Shaggy Inkcap (Coprinus comatus).
Glistening Inkcap (Coprinellus micaceus) usually found on tree stumps.
Fairy Inkcaps (Coprinellus disseminatus) are tiny very delicate and don’t last long.
Collared Earthstar (Geastrum triplex) past its best grows under Yews and has been reliably found for some years.
Rosy crust (Peniophora incarnata) looking like a spectacular plastic splodge of orange.
Abortiporus biennis, the red drops in this form are spectacular but watery and soon disperse.
Brown fungi are hard to identify, this could be Velvet Shank (Flammulina velutipes)
Probably Giant polypore (Meripilus giganteus) on fallen Beech.
Stump Puffball (Apioperdon pyriforme) commonly found in large troops on dead wood.
The white blob is a Myxomycete, a slime mould. The purple growths are the Jellydisc (Ascocoryne sarcoides) commonly found on broad leaved tree stumps.
Possibly Wood Hedgehog (Hydnum repandum)?
