 The winter bonnet ( M. tintinnabulum ) is a northern European species that is much smaller ( cap diameter up to 2 @.@ 6 cm ( 1 @.@ 0 in ) across ) and has a brown cap , and has ragged hairs at the base . It generally appears in late autumn to early winter on the stumps of deciduous trees , especially beech . It has pip @-@ shaped spores that are smaller than M. galericulata , around 4 @.@ 5 – 5 @.@ 5 by 2 @.@ 5 – 2 @.@ 8 µm . M. maculata develops pink stains on its gills as it matures ; its spores are 7 – 9 by 4 – 5 μm . Another similar species is M. inclinata , which can be distinguished by gills bearing reddish spots , which may become entirely red with age . It also has whitish , slender , threadlike flecks on the stalk . M. parabolica is thinner , and more fragile . Another Mycena that grows in clusters on decaying hardwoods is M. haematopus , but this species has a vinaceous @-@ brown cap with a scalloped margin , and a stem that bleeds reddish @-@ brown juice when injured . M. excisa closely resembles M. galericulata , but can be distinguished microscopically by the presence of both smooth and roughened cystidia ( bearing finger @-@ like projections ) .
