Arrhenia Peltigerina
''Arrhenia'' is a genus of fungi in the family Hygrophoraceae. ''Arrhenia'' also includes species formerly placed in the genera ''Leptoglossum'' and ''Phaeotellus'' and the lectotype species itself has an unusual growth form that would not normally be called agaricoid. All of the species grow in association with photosynthetic cryptogams such as mosses, including peat moss, and alga scums on decaying wood, and soil crusts consisting of mixes of such organisms. Typically the basidiocarp, fruitbodies of ''Arrhenia'' species are grey to black or blackish brown, being pigmented by incrusting melanin, melanized pigments on the hyphae. Etymology ''Arrhenia'' was named for the Swedish botanist Johan Peter Arrhenius. Species , Index Fungorum accepts 50 species of ''Arrhenia'': *''Arrhenia acerosa, A. acerosa'' (Fr.)

Omphalina
''Omphalina'' is a genus of small agarics with white, nonamyloid, basidiospores and decurrent gills. Typically the cap has a deep central depression giving the umbrella-like to funnel-shaped cap the appearance of a belly button, or a belly with a navel. Similarly-shaped agarics are said to be omphalinoid in appearance. Etymology ''Omphalina'' is the diminutive of ''Omphalia'' which is a reference to the belly button or navel-like appearance of the small dome-shaped caps with a central depression. It derives from the Greek word omphalos. Historical nomenclatural confusion The generic name ''Omphalina'' is an ancient one, linked to the even older mushroom name ''Omphalia'' which cannot be used because it is an illegitimate later homonym. Historically, the former was generally applied to any white-spored, similarly sized and shaped mushroom. As a result, many species that still are labeled ''Omphalina'', or were labeled ''Omphalia'' are in fact not true Omphalinas. The now conserve ...
