What are the smells of mulch?
2. Stinkhorns – Stinkhorns are commonly seen in mulch and the first indication of their presence, other than the much defined reddish-orange color and wiffle-ball or octopus-like shape, is the odor. Yes, these fungal beauties get their name from the fact that they stink. Yet, there’s a purpose for this unpleasant odor – to attract flies. They’re not a threat, they don’t harm plants and they won’t cause disease. In fact, their presence means organic material is breaking down, providing additional nourishment to surrounding plants. Once their job and lifecycle is complete, they will go away on their own.
What is slime mold?
Slime molds – Slime mold growth is usually confined to small areas in damp mulch or old, rotting logs. It easily recognized by its color, which may be bright pink, orange or yellow, and its frothy-like texture, similar to vomit.

What is the name of the fungus that sticks to the side of your house?
4. Artillery fungus – Artillery fungus feels right at home in cool, moist mulch. While it resembles a tiny cup with a black egg in the center, the sticky spores within that so-called egg eventually burst and are then windblown at considerable heights and distances – sticking to the side of your home, your car, or other surfaces. In fact, the name itself is derived from the Greek word for “spear thrower” because of its ability to propel these spores at such long distances. Although artillery fungus causes no real damage, it is unsightly and difficult to remove.

What is the best mulch for artillery fungus?
Penn State researchers have discovered that blending 40 percent used mushroom compost with landscape mulch greatly suppresses the artillery fungus. Mushroom compost, or mushroom soil, is the pasteurized material on which mushrooms are grown. After the final crops of mushrooms are picked, the used compost is pastuerized a second time and removed from the mushroom house. This valuable by-product (sometimes called "black gold") is often made available to gardeners and homeowners. Used mushroom compost has physical and chemical characteristics that make it ideal for blending with landscape mulch to enhance growth of horticultural plants. In addition, mushroom compost contains beneficial microbes that compete with, or actually destroy, nuisance fungi such as the artillery fungus and bird's nest fungi. Homeowners are increasingly interested in controlling nuisance fungi without the use of chemicals. Blending used mushroom compost with landscape mulch offers a "green" and environmentally friendly solution to reducing the harmful effects of the artillery fungus.
What do bird's nest fungi look like?
They resemble tiny, gray to brown bird's nests or splash cups with eggs. The nest is up to ¼ inch in diameter.
What do artillery fungi look like?
The cup is approximately ¹/₁₀ inch in diameter. Areas of mulch with artillery fungi may appear matted and lighter in color than the surrounding mulch. Are they a problem? They may be a problem. The fruiting body of this fungus orients itself toward bright surfaces, such as light-colored houses or parked automobiles. The artillery fungus "shoots" its black, sticky spore mass, which can be windblown as high as the second story of a house. The spore mass sticks to the side of a building or automobile, resembling a small speck of tar. You may also find them on the undersides of leaves on plants growing in mulched areas. Once in place, the spore mass is very difficult to remove without damaging the surface to which it is attached. If removed, it leaves a stain. A few of these spots are barely noticeable, but as they accumulate, they may become very unsightly on houses or cars.
What is the name of the fungus that grows in the cap of the fruiting body?
This fungus is called a stink-horn. It gets its name from the foul odor of the cap of the fruiting body.

What is the most resistant mulch?
In one study, the most resistant mulch was large pine bark nuggets. The large bark nuggets stay hard and dry, conditions that the artillery fungus does not like. Cypress mulch also performed well, as it probably contains some anti-fungal, anti-decay chemical (s).

Can artillery fungus spread?
People can also spread the artillery fungus in various ways. Some homeowners make the mistake of sanding, scraping, or otherwise removing the spore masses from the sides of their houses, and letting them fall onto their foundation mulch. Such spores are dormant, but very much alive. They germinate and infest the mulch.
Can artillery fungus grow in mulch?
If infested material is used for mulch, the artillery fungus may be already in the mulch when the load of mulch arrives at a job site, and may then grow rapidly along your foundation during cool moist conditions. However, this is likely a problem only when mulch is not composted, which subjects the mulch to higher internal temperatures.
How to Get Rid of Fungus in Mulch
