Larger than most of the other tuft-forming bonnet mushrooms found on stumps, the Common Bonnet (the type species of the Mycena genus) shows a distinct preference for decayed stumps and fallen trunks of deciduous broadleaf trees. Only very occasionally is it found on conifer stumps.
Look out for these pretty mushrooms in damp Beech and oak woods, where they are often at their most prolific in deep shade. Photographing mushrooms in such situations can be tricky, but provided there is room to use a tripod a long exposure is often preferable to using flash - unless of course you want the background to disappear into inky blackness, which can be very flattering for pale fungi such as the various woodland 'bonnet' species.
