| Armillaria ostoyae (above), is a variable mushroom that can be found either on wood or on the ground. It differs from L. decastes by having a well-developed ring around the stipe, and abundant large scales on the cap that can easily wash off.. | Clitocybe connata (Clitocybe dilatata, Lyophyllum connatum) (above), is also found on roadsides but differs from L. decastes by having white to whitish buff colours, decurrent white gills and ellipsoid spores. |

 |
| Gymnopus acervatus (Collybia acervata) (above), another mushroom that grows in dense heaps, always fruits on decaying or buried wood, has reddish to lavender brown colours and close to crowded gills that appear free. | Hypsizygus tessulates (above), causes brown rot on deciduous trees, has a tough texture rather than the fragile texture of L. decastes and differs by a combination of microscopic features. |
 |
 |
| Marasmius oreades (above), the fairy ring mushroom, is also found in lawns but has a reddish brown cap and fruits loosely in troops or rings rather than in tight clusters or tufts. | Pholiota terrestris (above),a smaller mushroom that also fruits in clusters on the ground along roads and paths, has a scaly cap and stipe and has brown spores. |
