Rickenella is a genus of brightly colored bryophilous agarics in the Hymenochaetales that have an omphalinoid morphology. They inhabit mosses on mossy soils, peats, tree trunks and logs in temperate regions of both the Northern and Southern Hemispheres. Phylogenetically related agarics are in the genera Contumyces, Gyroflexus, Loreleia, Cantharellopsis and Blasiphalia, as well as the stipitate-stereoid genera Muscinupta and Cotylidia. and the clavarioid genus, Alloclavaria.
Blasiphalia is a fungal genus in the family Repetobasidiaceae. A monotypic genus, it contains the honey colored omphalinoid agaric, Blasiphalia pseudogrisella, which grows with the liverwort genus Blasia. Phylogenetically related agarics are in the genera Rickenella, Gyroflexus, Loreleia, Cantharellopsis and Contumyces, as well as the stipitate-stereoid genera Muscinupta and Cotylidia and clavarioid genus, Alloclavaria. Blasiphalia is most similar to Rickenella and Contumyces, and was only just recognized as a distinct genus in 2007 based upon molecular analysis. The fungus is unique in parasitizing Blasia by forming clasping appresoria on its host's rhizoids. Its basidiospores also germinate on the host's gemmae and clasp them and therefore can be disseminated together with the gemmae.
Loreleia is a genus of brightly colored agarics in the Hymenochaetales that have an omphalinoid morphology. They inhabit mosses and or liverworts on soil in temperate regions of the Northern Hemisphere. Phylogenetically related agarics are in the genera Contumyces, Gyroflexus, Rickenella, Cantharellopsis and Blasiphalia, as well as the stipitate-stereoid genera Muscinupta and Cotylidia and the clavaroid genus, Alloclavaria. However, the large number of DNA base-pair changes causes a long-branch to form in phylogenetic analyses depicted as cladograms.
Gerronema is a genus of small- to medium-sized lignicolous agarics with white, nonamyloid, spores and decurrent gills. The genus was circumscribed by American mycologist Rolf Singer in 1951.
Lichenomphalia is both a basidiolichen and an agaric genus. Most of the species have inconspicuous lichenized thalli that consist of scattered, small, loose, nearly microscopic green balls or foliose small flakes containing single-celled green algae in the genus Coccomyxa, all interconnected by a loose network of hyphae. The agaric fruit bodies themselves are nonlichenized and resemble other types of omphalinoid mushrooms. These agarics lack clamp connections and do not form hymenial cystidia. The basidiospores are hyaline, smooth, thin-walled, and nonamyloid. Most of the species were originally classified in the genera Omphalina or Gerronema. Historically the species were classified with those other genera in the family, the Tricholomataceae together with the nonlichenized species. Lichenomphalia species can be grouped into brightly colored taxa, with vivid yellow and orange colors, versus the grey brown group, depending upon the microscopic pigmentation deposits. Molecular research comparing DNA sequences now place Lichenomphalia close to the redefined genus Arrhenia, which together with several other genera not traditionally considered to be related, fall within the newly redefined Hygrophoraceae.
The Physalacriaceae are a family of fungi in the order Agaricales. Species in the family have a widespread distribution, ranging from the Arctic, (Rhizomarasmius), to the tropics, e.g. Gloiocephala, and from marine sites (Mycaureola) and fresh waters (Gloiocephala) to semiarid forests (Xerula).
Cyptotrama is a genus of mushrooms in the family Physalacriaceae.
Rhodotus is a genus in the fungus family Physalacriaceae. There are two species in the genus with the best known, Rhodotus palmatus, called the netted rhodotus, the rosy veincap, or the wrinkled peach. This uncommon species has a circumboreal distribution, and has been collected in eastern North America, northern Africa, Europe, and Asia; declining populations in Europe have led to its appearance in over half of the European fungal Red Lists of threatened species. Typically found growing on the stumps and logs of rotting hardwoods, mature specimens may usually be identified by the pinkish color and the distinctive ridged and veined surface of their rubbery caps; variations in the color and quantity of light received during development lead to variations in the size, shape, and cap color of fruit bodies.
Collybia is a genus of mushrooms in the family Tricholomataceae. The genus has a widespread but rare distribution in northern temperate areas, and contains three species that grow on the decomposing remains of other mushrooms.
Rhizomarasmius is a genus of fungi in the family Physalacriaceae, containing about five species.
Pseudohiatula is a genus of fungi in the family Physalacriaceae. It was originally described as a subgenus of Mycena by the mycologist Rolf Singer before he moved to its own genus two years later. It was formerly thought to belong in the family Tricholomataceae, but a molecular phylogenetics study found it to be more closely The genus Cyptotrama in the Physalacriaceae. Rolf Singer had previously hypothesized these two genera to be closely related based on morphological features in 1986. It contains five species that are widely distributed in tropical areas.
Chromosera is a genus of fungi in the family Hygrophoraceae. Within the family Hygrophoraceae it is closely related to the genus Gloioxanthomyces. It contains five species. The generic name honors the mycologist Meinhard Moser, and also alludes (chromos) to the distinct coloration of the mushrooms, by overlapping 'chromos' with 'Moser', hence Chromosera.
Resinomycena is a genus of fungi in the mushroom family Mycenaceae. The genus contains at least eight species found in North America, Europe and eastern Asia. This genus of small white to tan colored agarics is saprophytic and colonizes leaf litter, bark, small twigs and decaying monocot vegetation. The fruitbodies are small and resemble Mycena or Marasmius or Hemimycena and are distinguished by amyloid spores, poorly dextrinoid tissues, and the abundant oily, resinous cystidia on the pileus, lamellae edges and stipes. One recently described species, Resinomycena fulgens from Japan that is a synonym of Resinomycena japonica, has luminescent fruitbodies.
Pseudohiatula cyatheae is a species of fungus in the family Physalacriaceae, and the type species of the genus Pseudohiatula. The species was first described by mycologist Rolf Singer in 1938.
Deconica is a genus of mushroom-forming fungi in the family Strophariaceae. It was formerly considered synonymous with Psilocybe until molecular studies showed that genus to be polyphyletic, made of two major clades: one containing bluing, hallucinogenic species, the other non-bluing and non-hallucinogenic species. Deconica contains species formerly classified in the sections Deconica and Coprophila of Psilocybe.
Phloeomana is a bark-inhabiting agaric fungal genus that produces fuscous-colored to whitish mycenoid to omphalinoid fruit bodies in temperate forests. In addition to the type species Phloeomana speirea, 4 other species, P. alba, P. clavata, P. hiemalis and P. minutula, have been placed in the genus. The genus is characterized by nonamyloid smooth, hyaline (translucent) basidiospores and tissues, poorly to moderately differentiated cheilocystidia, diverticulate pileipellis hyphae and general smooth stipe hyphae with scattered caulocystidia. It is one of several mushroom genera formerly classified most recently in Mycena, Omphalina, Hydropus, or Marasmiellus. Phylogenetically, Phloeomana is distant from the Mycenaceae and is closest to a clade or group that includes other former members of Mycena now in Atheniella and Hemimycena clearly excluded from the Mycenaceae and tentatively classified in the Porotheleaceae.
Marasmius limosus is a mushroom in the family Marasmiaceae.
Cryptomarasmius is a genus of fungi in the family Physalacriaceae.
Cibaomyces is an agaric fungal genus found in China, Japan, France, and Germany in forests containing Fagaceae. It resembles Hymenopellis radicata because of its size, radiating stipe and glutinous cap. Unlike species in the genus Hymenopellis, Cibaomyces produces spiny basidiospores. DNA sequence data show it to be distinct from Dactylosporina, another spiny-spored genus in the Physalacriaceae.
The genus Saproamanita contains about 24 species of agarics and is one of six genera in the family Amanitaceae. The others are Amanita, Catatrama, Limacellopsis, Zhuliangomyces and Limacella. Saproamanita are the saprophytic species in the Tribe Amaniteae, separately classified from the ectomycorrhizal species in the genus Amanita.
