Conservation Status: Not of concern
There are a number of smaller clitocybes that fruit in abundance on litter under trees. Their identification is challenging because they have few distinctive features to use in separating similar species. Clitocybe diatreta has shallowly depressed caps, with striate edge and a somewhat pruinose surface at first, pinkish to pinkish brown or vinaceous buff and darkest in the center when moist, then fading to very pale colors on drying. The gills are white then pinkish or buff, close and usually short decurrent. The stipe is colored like the cap, equal or slightly enlarged downward, with tomentum on the base that often is entangled in needles. C. diatreta occurs from our area across northern North America and Europe in needle beds under various conifers.
