We planted some big pots up with tomatoes and peppers from the Fullerton Arboretum, along with companion plants (pelargoniums onions nasturtium mint oregano marigolds and each other) sure to help our crop become a success (!). We used nice fresh bags of Kelloggs Patio Plus to fill these pots, watered everything in and sat back to watch things grow.
And grow they did. One morning I noticed spore prints all along the side of one of the pots, from a bunch of small now slimy mushrooms that had gone previously unnoticed under the tomato foliage.
A few days later there were some fresh buttons rising from the potting soil, which grew and opened into these small (about 1 inch across) corrugated caps.
The open caps began collapsing and then dissolved into black goo within a day or so.
My knowledge of mushrooms being almost non-existent, I hesitate to say what type this one is. However the gooey black stuff seems typical of the genus Coprinus, the aptly named Inky Cap mushrooms.
The fungi were liberally and fairly evenly distributed throughout the planted pot and they continue to pop up every couple of days. They don't seem to be causing a problem for the tomatoes which now have fruit setting; or any of the other vascular plants.
Did the mushroom spores or mycelia come in with the potting soil?
