We have a planter with a tomato plant and a bell pepper (capsicum) plant. A few months ago, during wet weather, many morels (specifically what appears to be Morchella rufobrunnea) started to appear next to the plants. Some research shows that the presence of this Morchella is quite common in our area and grows readily from wood chips in moist conditions.
While I'm not too upset by their presence (indeed they appear to be edible!), I'm wondering whether for the sake of the plants it's better to leave the fungi in, or to remove their visible parts.
Fungi seem to break down decomposing organic matter into components that the plants can perhaps use, but I want to be sure that 1) the fungi don't house other creatures that might harm the plants, or 2) that the fungi may affect the growth of the plants themselves.
