Do you have shotgun fungus
When using wood bark mulch to your landscape, once the landscape has a strong, crisp look to it.
Mulch also helps to maintain a uniform temperature of the soil and retains moisture. But sometimes,
the mulch can create an unexpected problem that many people do not even realize they have. During hot,
humid weeks in the heat of summer, it is not unusual for fungi to grow in the mulch around your house.
Most of these fungi are harmless to you and your plants. But it is a fungus that can literally splash
your home with a few brown spots!

Shotgun fungus (mushroom artillery AKA) is the best I do not know how it spreads. It forms a small
pinhead-sized bulbs, which collect water and other substances. These lamps are sensitive to light,
and when the bulbs are fully formed, they explode in the direction of the spread of the fungus
light in many different directions.
In a good wind, these lamps can explode and reach as far as twenty feet! The figure shows the
terry side of the house.
This type of fungus is very difficult to remove the objects to which it adheres.
Sometimes, soap, water and a little elbow grease does the trick, but it is very difficult to
completely remove.
The fungus usually develops in the forms and wood mulch that is why it usually ends up in your home.
At this stage, there is no fungicide to apply mulch to prevent the fungus from forming shotgun. What
I do to control fungi in the mulch around my house is simply to disrupt the fungus as soon as I see
it displayed. Sometimes I'll go, so that air can pass under it, or if I suspect that the fungus
shotgun I just put a layer of mulch on top of it to prevent the explosive action.
Granted fungi grow quickly in the soil and until I see the damage may already be done.
I wish I could give you better news.
Try cleaning the fungus in your home as soon as you detect it to prevent further damage.
