Bird Nest Fungus / Sphaerobolus (Artillery Fungus)
Scientific Name: Sphaerobolus stellatus
Order & Family: Order: Geastrales, Family: Sphaerobolaceae
Size: 1mm to 2mm in diameter (clinging spore mass)

Natural Habitat
Commonly found in damp environment, decaying wood, and especially landscape mulch near buildings.
Diet & Feeding
Saprotrophic; it gains nutrients by decomposing organic matter like wood chips and mulch.
Behavior Patterns
While technically a fungus and not a bug, it is often mistaken for one. It uses hydraulic pressure to 'fire' or jettison its black spore masses up to 20 feet away toward light sources.
Risks & Benefits
Non-toxic to humans/pets and beneficial for decomposition. However, it is a nuisance pest because the sticky spores are extremely difficult to remove from house siding and car paint.
