Anomoloma Niemelä & K.H. Larss. 2007
fungi genus in the amylocorticiaceae family
Anomoloma is a genus of crust fungi in the family Amylocorticiaceae. It was circumscribed by mycologists Tuomo Niemelä and Karl-Henrik Larsson in 2007. The generic name is derived from the Greek anomos, meaning "lawless", referring to the irregular rhizomorphic outline, and loma, meaning "margin" or "edge."
Corticiales K.H. Larss. 2007
fungi order in the class agaricomycetes
The Corticiales are an order of fungi in the class Agaricomycetes. The order is composed of corticioid fungi. Species within the order are generally saprotrophic, most of them wood-rotters, but several are parasitic on grasses or lichens. Plant pathogens of economic importance include Erythricium salmonicolor, Laetisaria fuciformis, Waitea circinata, Waitea oryzae, and Waitea zeae.
Trechisporales K.H. Larss. 2007
fungi order in the class agaricomycetes

fungi order in the class agaricomycetes
Amylocorticiales is an order of fungi in the class Agaricomycetes. The order was circumscribed in 2010 to contain mostly resupinate (crust-like) forms that have been referred to genera Anomoporia, Amyloathelia, Amylocorticiellum, Amylocorticium, Amyloxenasma, Anomoloma, Athelopsis, Ceraceomyces, Hypochniciellum, Leptosporomyces and Serpulomyces and the anomalous species, Athelia rolfsii, now classified in its own genus, Agroathelia.

Hydnellum fuligineoviolaceum (Kalchbr.) E. Larss., K.H. Larss. & Kõljalg 2019
fungi species in the bankeraceae family
Hydnellum fuligineoviolaceum is a species of tooth fungus in the family Bankeraceae. Found in northern Europe, it grows in association with coniferous trees, particularly Scots pine, and forms fruiting bodies that emerge from dry, chalky soils in mature forests. The species is classified by the IUCN as vulnerable due to habitat loss.
Brevicellicium olivascens (Bres.) K.H. Larss. & Hjortstam 1978
fungi species in the hydnodontaceae family
Brevicellicium olivascens is a species of crust-forming fungus in the family Hydnodontaceae that grows as thin, olive-tinted patches on decaying wood. First described by the Italian mycologist Giacomo Bresadola in 1892 as Odontia olivascens, it was later reclassified in 1978 by the Swedish mycologists Karl-Henrik Larsson and Erik Hjortstam, who created the new genus Brevicellicium (meaning "short cells") to accommodate it. This inconspicuous fungus forms delicate, web-like films only 0.1–0.3 millimetres thick that appear greyish-olive to olive-brown when fresh, becoming papery when dry, and
Brevicellicium K.H. Larss. & Hjortstam 1978
fungi genus in the hydnodontaceae family
Brevicellicium is a genus of fungi in the family Hydnodontaceae. The genus has a collectively widespread distribution, and contains 13 species.
Stereopsidales Sjökvist, E. Larss., B.E. Pfeil & K. H. Larss. 2013
fungi order in the class agaricomycetes
The Stereopsidales are an order of fungi in the class Agaricomycetes. There is a single family, Stereopsidaceae. It was first described in 2014 to contain the genera Stereopsis, which was until then classified in the order Polyporales, and Clavulicium, which was until then classified in the order Cantharellales. Molecular phylogenetics analysis showed these two genera to belong together in their own order. This order might belong in the subclass Phallomycetidae, but this relationship was poorly supported. The Stereopsidales contain corticoid fungi (Clavulicium and Stereopsis) and stalked,
Sidera Miettinen & K.H. Larss. 2010
fungi genus
Sidera is a genus of crust fungi in the order Hymenochaetales. Circumscribed in 2011, the genus is characterized by species that have whitish resupinate fruit bodies, crystal rosettes on specialized hyphae, and sausage-shaped (allantoid) spores.

Hydnellum underwoodii (Banker) E. Larss., K.H. Larss. & Kõljalg 2019
fungi species in the bankeraceae family
Hydnellum underwoodii is an inedible species of tooth fungus in the family Bankeraceae. Found in North America, it was described as new to science in 1906 by American mycologist Howard James Banker. Its reddish-brown, convex to flattened cap measures 5–14 cm (2.0–5.5 in) in diameter. Reddish-brown, partially erect scales adorn the cap surface. Spines on the cap underside are 1–3 mm long; they are initially white, becoming brown with grayish tips in age. The oval to spherical spores are 6–7.5 by 5.5–6.5 μm. The fungus fruits singly or scattered, on the ground in coniferous forests.

Pseudoxenasma is a fungal genus in the family Russulaceae, described in 1976. The genus is monotypic and contains the single species Pseudoxenasma verrucisporum, found in Sweden. The original description reads: "Fruitbody resupinate, effused, thin, hymenium more or less ceraceous, generally smooth. Hyphal system monomitic with the individual hyphae indistinct. Always with sulphocystidia i.e. with positive reaction to sulphovanilline as in Gloeocystidiellum. The cystidia are provided with globose apical appendices (schizopapilles according to Boidin and Lanquetin). Basidia clavate, in most
