Bird's nest fungi, or Nidulariaceae, are mushrooms that resemble small nests filled with tiny eggs. Despite their name, they have little to do with birds or nests, but instead got their name from their nest-like appearance. These mushrooms are unique in their appearance and dispersal mechanism, with the eggs containing millions of fungal spores that are ejected and dispersed by splashing water. They are commonly found in dead tree trunks, rotted timber, and decaying vegetation, and are known for their natural composting abilities. While they are not considered dangerous, they can become a nuisance when the spores stick to walls or other structures.

Bird's nest fungi: mushrooms that resemble nests with eggs
Bird's nest fungi, also known as Nidulariaceae, are mushrooms that resemble tiny egg-filled birds' nests. They are commonly found in disturbed areas with plant debris and mulch, such as trails, backyards, and gardens. They grow in large clusters, with each "nest" containing several "eggs". While they are named after birds' nests, they have little to do with birds or nests. Instead, their name comes from their resemblance to tiny nests filled with eggs.
Bird's nest fungi play an important ecological role in decomposing wood and other organic matter, including plant debris. This makes them beneficial for natural composting and cleaning up plant debris in gardens. They are not considered dangerous to plants, animals, or humans, and control measures are generally not necessary. However, the "eggs" of these fungi can become a nuisance when they are splashed out of the nest and stick to surfaces like cars, houses, or other structures, where they are difficult to remove.
The "eggs" of bird's nest fungi, also known as peridioles, serve as protective sacs containing millions of fungal spores. When raindrops or irrigation water land in the nests, the "eggs" are ejected up to four feet away, dispersing the spores and allowing them to grow into new fungal individuals. Each "egg" is connected to a funicular cord, a long, fine thread with a sticky tail, that helps it attach to a new surface and continue the life cycle.
Bird's nest fungi have a unique appearance, with caps or fruiting bodies that are only about a centimeter in diameter. The "eggs" are just a couple of millimeters wide and have a metallic sheen, resembling shiny river stones. While their edibility is not clear, they are generally considered inedible due to their small size and tough texture. Some Native American groups have been reported to infuse certain species in water and consume them as a beverage.

Bird's nest fungi are inedible
Bird's nest fungi, or Nidulariaceae, are a family of fungi that resemble tiny egg-filled birds' nests. They are commonly found in gardens, on hiking trails, and in other disturbed areas with plant debris and mulch. While they may be considered a nuisance by some, bird's nest fungi are not harmful to humans, animals, or plants and can even be beneficial by decomposing unwanted organic matter.
Despite their name, bird's nest fungi have little to do with birds or nests. They are called bird's nest fungi because of their nest-like appearance. The "eggs" inside the "nest" are actually spore-containing structures called peridioles, which are splashed out of the "nest" by raindrops and can travel several feet before sticking to another object.
The edibility of bird's nest fungi is not clear. Some sources state that bird's nest fungi are inedible due to their tough texture and small size. There are anecdotal reports of certain bird's nest fungi being infused in water and consumed as a beverage by Native Americans, but the physiological effects on humans have not been studied. Therefore, it is not recommended that humans consume bird's nest fungi.
If you find bird's nest fungi in your garden, you can simply enjoy their natural beauty and unique appearance. However, if the "eggs" become a nuisance by sticking to surfaces like cars, houses, or other structures, you can try raking the soil frequently, decreasing irrigation in shady areas, and using living mulches and edible ground covers instead of wood chips in your garden beds to reduce their occurrence.

They have natural composting abilities
Bird's nest fungi, or Nidulariaceae, are a family of fungi that resemble tiny egg-filled birds' nests. They are commonly found in dead tree trunks, rotted timber, wood mulch, bark chips, sawdust, decaying vegetation, or humus-rich soil. They are also seen in animal dung, as the peridioles can survive a journey through the digestive tracts of cows and horses.
Bird's nest fungi have natural composting abilities. They obtain nutrients by decomposing organic matter, mainly plant-based materials. This ecological role of decomposing wood makes them extremely common in disturbed areas with plant debris and mulch, such as trails and backyards. They tend to grow in large clusters, so it is not unusual to see ten to a hundred of these "nests" at once.
The "eggs" inside each "nest" contain millions of fungal spores that will disperse by splashing and grow into new fungal individuals. When drops of water from rain or irrigation land in the cups, they eject the peridioles, which can travel up to four feet away to reproduce. This unique dispersal mechanism makes bird's nest fungi stand out from other types of fungi.
Bird's nest fungi are beneficial to gardens as they help decompose unwanted organic matter and speed up the decomposition process by twofold. They reduce large chunks of plant debris into slivers that eventually decay and enrich the soil. However, they can become a nuisance when the peridioles stick to exterior walls, cars, or other structures, as they are quite adhesive and challenging to remove.
While the edibility of bird's nest fungi is unclear, they are not considered harmful to humans, animals, or plants, so control measures are generally unnecessary. If accidentally consumed, it is recommended to monitor for any unusual symptoms.

They can be a nuisance
Bird's nest fungi, or Nidulariaceae, are a family of fungi that resemble tiny egg-filled birds' nests. While these fungi are not considered dangerous to plants, animals, or humans, they can sometimes become a nuisance in certain settings.
The "eggs" inside each "nest" are called peridioles, which contain millions of fungal spores. When raindrops or irrigation water land in the nests, the peridioles are ejected and can travel several feet away. While this mechanism aids in the fungi's dispersal and reproduction, it can also lead to unwanted consequences.
The ejected peridioles can land on exterior walls of houses, cars, or other structures, where they stick and become challenging to remove due to their adhesive nature. This nuisance factor is heightened when bird's nest fungi grow in close proximity to human habitations. To mitigate this issue, it is recommended to maintain a distance of at least one foot between mulch and the edges of houses or buildings.
Additionally, bird's nest fungi thrive in disturbed areas with plant debris and mulch, such as backyards, gardens, and hiking trails. Their tendency to grow in large clusters can result in a significant presence, with tens or even hundreds of "nests" appearing simultaneously. While beneficial for natural composting and accelerating decomposition, this abundance can be a nuisance to those seeking a tidy or aesthetically pleasing outdoor space.
Furthermore, the extensive mycelium growth and abundant peridioles of bird's nest fungi make their eradication impractical. Raking or plowing the mulched soil can disturb the fungi and encourage the colonization of other fungi species, eventually leading to a reduction in bird's nest fungi numbers. However, this approach may be time-consuming and labor-intensive.
While fungicide may decrease the population of bird's nest fungi, it is generally not recommended due to its potential harm to the environment and limited effectiveness on wood surfaces. Therefore, physical methods of disruption and prevention, such as raking and minimizing irrigation, are often the preferred methods of managing the potential nuisance caused by bird's nest fungi.

They are not harmful to humans, animals or plants
Bird's nest fungi, or Nidulariaceae, are a family of fungi that resemble tiny egg-filled birds' nests. They are commonly found in dead tree trunks, rotted timber, wood mulch, bark chips, sawdust, decaying vegetation, or humus-rich soil. While they may be considered a nuisance in certain situations, bird's nest fungi are not harmful to humans, animals, or plants.
The ecological role of bird's nest fungi is to decompose organic matter, primarily plant-based materials. This process of decomposition is beneficial for the environment as it helps to break down unwanted organic waste, enriching the soil and facilitating the growth of new plants. Despite their name, bird's nest fungi have little to do with birds or nests. Rather, they earned their name due to their resemblance to tiny bird nests filled with eggs.
While the edibility of bird's nest fungi is not clear, they are generally considered inedible due to their small size and tough texture. There have been anecdotal reports of certain specimens being infused in water and consumed as a beverage by Native Americans, but the physiological effects on humans have not been studied. Therefore, it is recommended to refrain from consuming bird's nest fungi and instead appreciate their natural beauty.
Bird's nest fungi can become a nuisance when their "eggs," or peridioles, splash onto nearby surfaces and structures, where they can be difficult to remove due to their adhesive nature. In such cases, it is suggested to keep mulch at least one foot away from houses or other structures to reduce the chances of peridioles landing on them. Additionally, raking the soil, decreasing irrigation, and using living mulches and edible ground covers can help deter the growth of bird's nest fungi.
Overall, while bird's nest fungi may require some management in certain contexts, they play a beneficial role in the ecosystem by aiding the decomposition of organic matter and are not harmful to humans, animals, or plants.
