A series of photos of the mushroom Leucocoprinus birnbaumii (also L. luteus, the yellow parasol mushroom) that sprouted in a bathroom houseplant last month. We think they came with a recent batch of potting soil we got last summer. Now they are popping up in all of our plants. From first to last - this all happened within a week.
I love going outdoors and finding new fungi, but its nice sometimes when the mushroom comes to you.
