Chicken’s nest fungi, sphere throwers and shotgun fungi
Chicken’s nest fungi (Mycocalia, Nidularia, Nidula, Cyathus, and Crucibulum spp.), sphere throwers (Sphaerobolus spp.), and shotgun fungi (Pilobolus spp.) are three separate teams of fungi with many similarities.
They’re all saprophytes, which develop on manure or decaying wooden. Since these fungi reside solely on decaying plant matter, they don’t hurt residing vegetation.

Within the backyard, the tiny fungi (underneath 1/4 inch tall) are often discovered on the floor of soil that has been enriched with manure, sawdust or wooden chips. They will also be discovered on outdated boards used to edge backyard beds and on wood plant labels and stakes.
The fungi are often unfold in manure, however some species could contaminate seed mixes.

All of those fungi can forcibly eject their spores in arduous egg-like constructions known as peridioles. These constructions could be ejected 3 toes or extra. The sticky spore instances adhere to plant leaves and different surfaces, together with house siding and patio furnishings.
These fungi are hardly ever observed until they’re introduced indoors on container-grown vegetation. The primary signal is shiny black or darkish brown growths that appear like seeds or bugs on the leaves. These are the egg-like constructions which were ejected by the fungi. They are often picked off the leaves.
To assist management these fungi, take away any fungal fruiting our bodies from the floor of the soil. Repot the plant in a potting medium that doesn’t include manure or wooden to forestall the fungi from returning.
Chicken’s nest fungi
- Appear to be miniature chook’s nests or cups.
- Shiny peridioles are nestled inside like eggs.
- Often just one/4 inch in peak or diameter.
- Generally mild brown however could also be white, grey, yellow or rust coloured.
- The shiny peridioles are usually black or darkish brown however can also be white.
- Immature fruiting our bodies appear like tiny puffballs, which open into cups as they mature.
The peridioles of chook’s nest fungi are splashed out of the nest by falling water drops. The scale and form of the nest are such that the power of a water drop hitting the underside of the cup is sufficient to throw the peridioles over one yard from the nest.
- When a peridiole hits a strong object reminiscent of a leaf or twig, it sticks to the floor in certainly one of two methods. Fungi within the genera Mycocalia, Nidularia and Nidula have sticky peridioles.
- Within the genera Cyathus and Crucibulum, the peridiole is connected to the nest by a coiled twine. When the peridiole is ejected from the nest, the twine separates from the nest, giving the peridiole a four-inch tail. The top of the tail is sticky. When it sticks to a twig or stem, the peridiole swings round its anchor level, wrapping the twine across the stem.

Most chook’s nest fungi in Minnesota belong to Cyathus or Crucibulum.
Sphere throwers (Sphaerobolus spp.)
- Develop on rotting wooden in lots of the similar locations as chook’s nest fungi.
- The whitish or yellowish-pink immature fruiting our bodies are spherical balls much like immature chook’s nest fungi.
- Because the fruiting our bodies mature, the outer layer of the ball peels again to type a cup with a single spherical peridiole inside. This cup is definitely two cups, one inside the opposite, joined on the rim.
- Strain builds up between the 2 cups, ultimately inflicting the interior cup to explosively invert, or flip inside out.
- The power of the inversion launches the peridiole, which might journey greater than 5 yards earlier than sticking to any floor it impacts.
Shotgun fungi (Pilobolus spp.)
- Develop largely on outdated horse manure.
- Clear, glasslike fruiting physique consists of a slender stalk topped with a swollen bulb.
- A shiny black peridiole rests on high of the bulb.
Pilobolus bends towards the sunshine, which ensures the clearest path for the peridiole to journey. The fungus senses the route of the sunshine with mild delicate pigments on the base of the bulb. So long as these pigments are illuminated, they ship a sign to bend. The bending stops when the opaque peridiole is pointing instantly on the mild supply, shading the pigments.
If grown at the hours of darkness, the stalks will all level straight up. The swollen bulb is full of sugar, which absorbs water till the stress contained in the bulb is 5 occasions the stress exterior. Because the fruiting physique matures, the partitions weaken underneath the peridiole. Ultimately the stress causes the bulb to rupture, sending the sticky peridiole flying.
These ballistic fungi, every with its distinctive methodology of spore dispersal, is usually a fascinating introduction to the world of fungi. A cautious search of the damp corners of your backyard within the fall will most likely reveal quite a few chook’s nest fungi, sphere throwers and shotgun fungi.
