Xeromphalina campanella is very common in our coniferous forests. Its coloration, cap shape, decurrent gills, tough thin stipe, absence of an annulus, habitat, and amyloid spores distinguish this species from similar fungi. Hygrophoropsis aurantiaca is similar in color, but larger with dichotomously branched decurrent gills and dextrinoid spores. In our area it tends to grow on wood chips.
