Hi i'm from in sugarland, tx, usa. which is next to houston, tx. I started a raised bed garden a few weeks ago. I recently added organic fertilizer. After some rains the past few days, about 100 of these mushroom looking things came up! i was disturbed. I did some research and tried spraying diluted 3% hydrogen peroxide yesterday on them and that did not work :( Any ideas what it is and how to get rid of it? Thanks!
Definitely in the Coprinus family. Your mushroom is likely closely related to Parasola plicatilis. They are completely harmless, no need to get rid of them. Killing the mushroom (with H2O2 or anything else) is like picking the apples off a tree to try and kill the tree. The mycelium (from which the mushrooms come up from) is in your wood chips/fertilizer/ground and is impossible to separate. The mycelium actually does a lot of good for the ground. Your mushrooms will go away when moisture & humidity go down, eventually.
