michi Posted May 13, 2019 Report Share Posted May 13, 2019 (edited) Hello These mushrooms randomly started to grow beside my lemon tree. I'm wondering which species it is and whether I should get rid of it to protect my young lemon tree. If they are beneficial for my tree (which I learnt some mushrooms can be) I would leave them be and enjoy this little surprise The pot they are growing in is indoors. I'm in Vancouver, Canada. The gills of the mushrooms are white. I can't smell any special odor, because the lemon leaves are overpowering. Thank you for your help!

bobby b Posted May 13, 2019 Report Share Posted May 13, 2019 It looks like Leucoagaricus americanus, the reddening lepiota, but Kuo says there are many small lepiotas that are hard to ID. There's a yellow lepiota, Leucocoprinus birnbaumii, that people find in their flower pots. Kuo says most are saprobic and won't harm plants. If you have young children or pets that would eat them, that could be a big problem as many mushrooms are poisonous. Dave W will be able to give more accurate info.

Dave W Posted May 13, 2019 Report Share Posted May 13, 2019 I agree, these do look like Leucoagaricus americanus. How large is that pot? Unless it's massive, these are on the small size for this species. The habitat is certainly not typical. As bobby said, we need to also consider genus Lepiota here. Some Lepiota mushrooms are poisonous https://www.mycoquebec.org/bas.php?trie=L&l=l&nom=Lepiota felina / Lépiote féline&tag=Lepiota felina&gro=12 Probably just L. americanus. But to be on the safe side, I suggest removing and discarding the mushrooms. Quote Link to comment Share on other sites More sharing options...
michi Posted May 14, 2019 Author Report Share Posted May 14, 2019 Thank you so much for your answers Bobby and Dave. That pot is pretty small. The mushrooms are about the size of my thumb. So the Lepiota mushrooms seem to match better looking at the size of what's growing there. Quote Link to comment Share on other sites More sharing options...
vitog Posted May 14, 2019 Report Share Posted May 14, 2019 I see small Lepiotas like the ones in the photo frequently in the fall; but I avoid them and have never tried to identify them, because there are several similar species and some are known to be poisonous. If there is any chance that someone or a pet might eat these, I would definitely remove them as soon as they appear. Their presence or absence should have no impact on the plants in the pot.

Dave W Posted May 14, 2019 Report Share Posted May 14, 2019 Very small --size of a thumb-- favors genus Lepiota. Maybe L. cristata https://en.wikipedia.org/wiki/Lepiota_cristata . Agree with vitog, removing the mushrooms will not negatively impact the plant in the pot. Lepiota mushrooms grow from a fungus that is saprobic (ie. not mycorrhizal; does not form a symbiotic relationship with a plant). Quote Link to comment Share on other sites More sharing options...

Dave W Posted July 3, 2021 Report Share Posted July 3, 2021 Been awhile since I visited this discussion. New ID proposal... Leucocoprinus brebissonii, https://en.wikipedia.org/wiki/Leucocoprinus_brebissonii . Quote Link to comment Share on other sites More sharing options...
Dale Posted June 14, 2022 Report Share Posted June 14, 2022 My lemon tree make what looks like Oyster mushrooms, but they grow individually. Quote Link to comment Share on other sites More sharing options...
Dave W Posted June 15, 2022 Report Share Posted June 15, 2022 Best to create a new discussion when the topic is changed. I don't have a confident ID proposal for this. But, I don't think it's a species of Pleurotus (ie. it's not an Oyster Mushroom). Maybe compare with species of Hohenbuehelia? If it's a species from this genus then microscopic analysis would be useful. Quote Link to comment Share on other sites More sharing options...

Leucocoprinus brebissonii, https://en.wikipedia.org/wiki/Leucocoprinus_brebissonii . I second this ID, I have the same mushrooms growing in a plant in my bathroom and Leucocoprinus brebissonii is the closest match ive seen.

Dave W Posted November 28, 2022 Report Share Posted November 28, 2022 I just ran across something that reminded me of this discussion. https://www.mycoquebec.org/bas.php?trie=L&l=l&nom=Leucocoprinus ianthinus / Lépiote violette&tag=Leucocoprinus ianthinus&gro=12 Quote Link to comment Share on other sites More sharing options...
Bubbles Posted August 29, 2023 Report Share Posted August 29, 2023 Growing indoors with my Clivia. I repotted it this year , so I’m guessing it came with the compost … Quote Link to comment Share on other sites More sharing options...
Dave W Posted August 30, 2023 Report Share Posted August 30, 2023 A species of Leucocoprinus. Compare with L. ianthinus. Quote Link to comment Share on other sites More sharing options...
