Deer Shield or Grey Knight?



What a fine specimen! We thought it was a Deer Shield (Pluteus cervinus), a relatively common mushroom that usually grows on rotting deciduous wood. It’s a match for the picture in the Collins Complete Guide that we use but other sources show a mushroom with a lighter colour so we’re not sure – it apparently gets its common name from its dull brown colour. All very confusing, and DNA studies apparently suggest that not everything labelled as Pluteus cervinus really is. We should have looked harder at the gills (which should have been free) and and the spores (salmon pink).

However, sporesmouldsandfungi suggested via a comment that it might actually be a Tricholoma, perhaps Tricholoma terreum (the Grey Knight). I though that was a fan of pine woods rather than beech but maybe ours was on a long gone pine stump. We’ll have to hunt around and try and find another one for detailed study.

  1. We’re total amateurs just looking at the guidebooks so all suggestions are welcome! Thanks. I admit I was swayed by the fact that the picture is such an exact match to the Collins guide Pluteus. I wondered about a Grey Shield but was less drawn to it because ours was deep brown rather than deep grey and was in beech/ash woodland rather than amongst conifers (though maybe it was on an old pine sump?) Anyway, now I have your suggestion we’ll have a hunt around and do a more detailed examination if we find another. Congratulations on your own very interesting blog btw.
