Assuming these are the same fungi (the buds look consistent), I should have full-grown mushrooms tomorrow or Friday. They'll likely collapse over the weekend. By this time next week, they'll have nearly decomposed into nothing.

@lrhodes they look amazing. The ones in the second photo look like puffballs or earthballs now but I suspect they'll open up into what you saw before.

Beautiful ridges when they are fully grown. Possible they came in with the compost, although spores are everywhere, all the time, so you never know.

@glyph might have na idea..

@ephemeral @glyph No compost here, so that's not it. The soil is from a lavender plant I bought last summer. The lavender died over the winter, so I've repurposed the pot for habeñeros (which was the only small-space suitable seed on the rack where I buy seeds). No mushrooms sprouted in that pot last summer, but I did have a problem with pigeons roosting in it a few weeks ago (hence the stakes), so I'm guessing they brought the spores.

@lrhodes

Interesting.

Could be the pigeons, but then it could be anything really. Spores are so ubiquitous that it might have just been a wind. Or maybe the dead lavender root. The strange wonder of fungi.

Coincidentally, I had a fungal outbreak with some elephantine yellow chilis last year. I just let them grow. Not similar mushrooms, just a coincidence.

Would love to know what yours are when you figure it out! I hope they don't harm the plant.

@glyph

@ephemeral @glyph Jist thought of something. All of the mushrooms so far have sprouted at the rim of the pot, on three different sides. Seems like that would argue for connection with the lavender roots, yeah? It was a relatively mature plant, so I have little doubt the root ends stretched to the sides of the pot.

@lrhodes @glyph

Ha, that would be interesting too. When tree saplings are pulled from the ground they bring with them lots of species of fungi in the soil (and sometimes they lose connections to other helpful fungi).

It's very possible the flowers brought some friends.

Or some enemies.

@lrhodes @ephemeral

it's cool to read the questions you're asking and to hear your thought-processes!

species in Leucocoprinus are saprophytes - so there's no association with the lavender roots. saprophytes tend to form shallow networks at the soil surface.

many species tend to fruit at the margins of the substrate - in your case it might have something to do with tiny differences in conditions between the rim of the pot and the center (perhaps more moisture is present at the rim).

@lrhodes and this is the difference between my amateur guesswork and expertise! Thanks @glyph

How did you identify Leucocoprinus? I get so intimidated by the less immediately obvious toadstools that I don't even know where to start!

@ephemeral @lrhodes

in this particular case i had the advantage of previous experience: the "flowerpot parasol" is relatively common around the world, especially in greenhouses, and i had previously encountered it in my hometown many years ago. so it was more a case of immediate recognition than taxonomic detective work.

some features of leucocoprinus:

- finely-scaled cap
- fragile ring on stem
- gills free from the stem (not directly attached at center)
- cap margin lined / grooved

@ephemeral @lrhodes

i should say that my taxonomic and identification knowledge is still super basic. answering questions like this helps me to learn, so thanks for voicing your curiosity!
