Agaricomorpha
Agaricomorpha is a genus of rove beetles in the family Staphylinidae, subfamily Aleocharinae. It was established by Ashe in 1984 and belongs to the tribe Homalotini and subtribe Gyrophaenina. Members of this subtribe are generally associated with fungi, particularly fleshy mushrooms. The genus is rarely encountered and poorly documented in scientific literature.
Aneurus pygmaeus
Aneurus pygmaeus is a species of flat bug in the family Aradidae, described by Kormilev in 1966. The genus Aneurus comprises small, cryptic bugs associated with dead wood and fungi. As with other aradids, this species likely inhabits concealed microhabitats beneath bark or within decaying wood. The specific epithet 'pygmaeus' refers to its diminutive size. Information regarding its biology and distribution remains limited in available literature.
Asteiidae
Fine Flies
Asteiidae is a small family of acalyptrate flies comprising approximately 130 species in 10 genera worldwide. Adults are minute to small (1–3 mm), delicate flies with thin bodies and relatively long, transparent wings. The family is rarely collected, likely due to their small size and inconspicuous habits. Most species are found in forested habitats, with adults often observed on flowers, low vegetation, and fungi.
Atomaria
silken fungus beetles
Atomaria is a genus of silken fungus beetles in the family Cryptophagidae, comprising more than 160 described species. These small beetles are associated with fungal habitats and are part of the diverse beetle fauna found in decaying organic matter. The genus was established by Stephens in 1829 and remains taxonomically active with ongoing species descriptions.
Atomaria lineola
Atomaria lineola is a small beetle species in the family Cryptophagidae, known as silken fungus beetles. The genus Atomaria is recognized by the distinctive 'tuning fork' branching pattern in one of the wing veins. This species was described by Notman in 1920 and occurs in North America. Members of this genus are typically associated with fungi and decaying organic matter.
Colonidae
Colonidae is a small family of beetles in the superfamily Staphylinoidea, commonly known as colon beetles. The family contains approximately 50 described species in the single genus *Colon*. These beetles are small, compact, and primarily associated with decaying organic matter and fungi. They are closely related to the rove beetles (Staphylinidae) but are distinguished by their more rounded body form and reduced elytra that still cover most of the abdomen.
Diplocoelus rudis
false skin beetle
Diplocoelus rudis is a species of false skin beetle in the family Biphyllidae. It was described by LeConte in 1863. The species is found in North America, though specific details about its biology and ecology remain poorly documented in available literature. As a member of the Biphyllidae family, it belongs to a small group of beetles commonly known as false skin beetles, which are associated with fungi and decaying organic matter.
Eleates depressus
Conk-loving Darkling Beetle
Eleates depressus is a small darkling beetle in the family Tenebrionidae, commonly known as the Conk-loving Darkling Beetle. The species has been recorded from multiple Canadian provinces including British Columbia, Manitoba, New Brunswick, Northwest Territories, and Ontario. It is associated with conks (bracket fungi) on trees, where adults are found. The species was originally described by Randall in 1838.
Enchodes
Enchodes is a genus of beetles in the family Melandryidae (false darkling beetles), established by LeConte in 1866. Members of this genus are small to medium-sized beetles associated with decaying wood and fungal habitats. The genus contains multiple species distributed primarily in North America.
Holoparamecus pacificus
handsome fungus beetle
Holoparamecus pacificus is a species of handsome fungus beetle in the family Endomychidae, first described by John Lawrence LeConte in 1863. The species is recorded from North America. Members of the genus Holoparamecus are small beetles associated with fungal habitats. Beyond its taxonomic placement and geographic distribution, specific ecological and biological details for this species remain poorly documented in the scientific literature.
Melandryidae
False Darkling Beetles
Melandryidae, or false darkling beetles, is a family of beetles in the superfamily Tenebrionoidea containing approximately 420 species in 60 genera. Members are found worldwide and are primarily associated with rotting wood and wood-decomposing fungi in both larval and adult stages. The family has a fossil record extending back to at least the mid-Cretaceous (Albian-Cenomanian) with specimens in Burmese amber, and the tribe Hypulini is documented from late Eocene Baltic amber. Many species are saproxylic, inhabiting dead and decaying wood in forest ecosystems.
Monoclona
fungus gnats
Monoclona is a genus of fungus gnats in the family Mycetophilidae, comprising approximately 18 described species. The genus was established by Mik in 1886 and belongs to the subfamily Sciophilinae. At least one species, Monoclona carambeiensis, has been described from the Neotropical region with complete life cycle documentation. The genus has been recorded in Europe (Denmark, Norway, Sweden) and South America (Brazil).
Mycomya obliqua
Mycomya obliqua is a species of fungus gnat in the family Mycetophilidae, described by Thomas Say in 1824. As a member of the subfamily Mycomyinae, it belongs to a diverse group of small flies whose larvae typically develop in decaying organic matter, particularly fungi. The species epithet "obliqua" refers to an oblique or slanted feature of its morphology, though the specific trait referenced is not detailed in available sources. Very few observations of this species have been recorded, with only three documented occurrences in iNaturalist.
Oxyporus femoralis
Oxyporus femoralis is a species of rove beetle in the family Staphylinidae, first described by Gravenhorst in 1802. The species belongs to the subfamily Oxyporinae, a group of fungi-associated beetles. It has been recorded across eastern North America from Canada to the southern United States.
Oxyporus quinquemaculatus
A rove beetle in the family Staphylinidae, currently classified under the genus Pseudoxyporus. The species name refers to five spots. This small beetle belongs to the subfamily Oxyporinae, a group of fungi-associated rove beetles.
Poecilominettia
Poecilominettia is a genus of small flies in the family Lauxaniidae, established by Hendel in 1932. The genus contains more than 60 described species, placing it among the more species-rich genera in its family. Members are found across various regions, though detailed species-level distributions remain incompletely documented. Like other lauxaniid flies, they are associated with decomposing plant matter and fungal habitats.
Sciophilinae
fungus gnats
Sciophilinae is a subfamily of fungus gnats within the family Mycetophilidae, comprising at least 40 genera and 340 described species. Members are found in humid environments, often associated with decaying wood and fungi. The subfamily has a global distribution with significant diversity in Neotropical, Nearctic, and Palearctic regions. Natural history information remains limited for most species.
Tachinus fumipennis
Tachinus fumipennis is a rove beetle (family Staphylinidae) found across much of North America. The species belongs to the genus Tachinus, a group of moderately sized rove beetles often associated with decaying organic matter and fungi. As with many staphylinids, it likely plays a role in nutrient cycling through its feeding habits, though specific biological details for this species remain poorly documented in published literature. The species is distinguished from congeners by subtle morphological features of the elytra and antennae.
Tenebroides rugosipennis
Tenebroides rugosipennis is a species of bark-gnawing beetle in the family Trogossitidae. Members of this genus are generally associated with dead or decaying wood and fungal habitats. This species is poorly documented in scientific literature, with minimal published information available regarding its biology and ecology. It belongs to a family containing both predatory and mycophagous species.
Triplax puncticeps
pleasing fungus beetle
Triplax puncticeps is a small beetle in the pleasing fungus beetle family Erotylidae, found in North America. Like other members of its genus, it is associated with fungi, though specific ecological details for this species remain poorly documented. The species was described by Casey in 1916.
