Stilbum vulgare Tode (1790) |
Stilbum is a genus of fungi in the family Chionosphaeraceae. [1] Though many species were formerly referred to the genus, it is effectively monotypic since the type species, Stilbum vulgare, currently has no close relative. [2] Stilbum vulgare forms groups of minute, gelatinous, synnema-like basidiocarps (fruit bodies) up to 0.5 mm tall with a distinct stem and inflated, fertile head. Microscopically, it produces auricularioid (laterally septate) basidia and basidiospores that germinate by budding off yeast cells. The species has been collected on rotting wood and old agaric fruit bodies and may be a parasite of other fungi. It was originally described from Europe, but is also known from Asia, North America, and Australia. [2] [3]
Stilbum was described in 1790 by German mycologist Heinrich Julius Tode. [4] As well as Stilbum vulgare, he included several other species of similar size, texture, and shape within the genus. In the following century, other authors added over 200 species to Stilbum on the same basis. Re-examination of specimens in the twentieth century showed, however, that nearly all these species were anamorphic members of the Ascomycota, many of them subsequently assigned to the genus Stilbella . [5] Some species originally described in the genus Stilbum remain unassigned and are treated as nomina dubia since authentic material is lacking and the original descriptions are inadequate for identification.

Sordariomycetes is a class of fungi in the subdivision Pezizomycotina (Ascomycota). It is the second-largest class of Ascomycota, with a worldwide distribution that mostly accommodates terrestrial based taxa, although several can also be found in aquatic habitats. Some are phytopathogens that can cause leaf, stem, and root diseases in a wide variety of hosts, while other genera can cause diseases in arthropods and mammals.
Nectria is a genus of Ascomycete fungi. They are most often encountered as saprophytes on decaying wood but some species can also occur as parasites of trees, especially fruit trees and a number of other hardwood trees. Some species are significant pests causing diseases such as apple canker, Nectria twig blight, and coral spot in orchards.
Endogonales is an order of fungi within the phylum of Zygomycota, and in class Endogonomycetes.
Agaricomycotina is one of three subdivisions of the Basidiomycota, and represents all of the fungi which form macroscopic fruiting bodies. Agaricomycotina contains over 30,000 species, divided into three classes: Tremellomycetes, Dacrymycetes, and Agaricomycetes. Around 98% of the species are in the class Agaricomycetes, including all the agarics, bracket fungi, clavarioid fungi, corticioid fungi, and gasteroid fungi. Tremellomycetes contains many basidiomycete yeasts and some conspicuous jelly fungi. Dacrymycetes contains a further group of jelly fungi. These taxa are founded on molecular research, based on cladistic analysis of DNA sequences, and supersede earlier morphology-based classifications. Agaricomycotina contains nearly one third of all described species of fungi.
Pleosporaceae is a family of sac fungi. They are pathogenic to humans or saprobic on woody and dead herbaceous stems or leaves.
The Botryosphaeriales are an order of sac fungi (Ascomycetes), placed under class Dothideomycetes. Some species are parasites, causing leaf spot, plant rot, die-back or cankers, but they can also be saprophytes or endophytes. They occur world-wide on many hosts. For example, in China, infections related to Botryosphaeriales have been recorded on numerous hosts such as grapes, Caragana arborescens,Cercis chinensis, Eucalyptus, Chinese hackberry, blueberry, forest trees, and various other woody hosts.
Crucibulum is a genus in the Nidulariaceae, a family of fungi whose fruiting bodies resemble tiny egg-filled bird's nests. Often called "splash cups", the fruiting bodies are adapted for spore dispersal by using the kinetic energy of falling drops of rain. The "eggs" inside the bird's nests are hard waxy shells containing spores, and tend to stick to whatever nearby herbage they land on, thus increasing the odds of being consumed and dispersed by herbivorous animals. Members of this genus are saprobic, obtaining nutrients from dead organic matter, and are typically found growing on decayed wood and wood debris. The three known Crucibulum species are distinguished from other genera of the Nidulariaceae by their relatively simple funiculus – a cord of hyphae that connects the peridiole to the exterior of the bird's nest.
Lophiostoma is a genus of ascomycetous fungi in the family Lophiostomataceae.
The Microascaceae are a family of fungi in the class Sordariomycetes, subclass Hypocreomycetidae. The family was published by David Malloch in 1970, an emended description based on Everet Stanley Luttrell's original 1951 publication. Family was updated in 2020.
Navicella is a genus of fungi, that had been placed in the family Massariaceae. According to Wijayawardene et al. 2020, it is now placed in the Melanommataceae family.
The Lulworthiaceae are a family of marine fungi in the Ascomycota, class Sordariomycetes. Species in the family have a widespread distribution in both temperate and tropical oceans, and are typically found growing on submerged wood or on seaweed. In 2000, Molecular analysis of several species of Lulworthia and Lindra led to the reassignment of their parent genera to the new order Lulworthiales in addition to the new family Lulworthiaceae. In 2020, a large fungi study added more genera to the family.
The clavarioid fungi are a group of fungi in the Basidiomycota typically having erect, simple or branched basidiocarps that are formed on the ground, on decaying vegetation, or on dead wood. They are colloquially called club fungi and coral fungi.
The cyphelloid fungi are a group of fungi in the Basidiomycota that have disc-, tube-, or cup-shaped basidiocarps, resembling species of discomycetes in the Ascomycota. They were originally referred to the genus Cyphella and subsequently to the family Cyphellaceae, but are now known to be much more diverse and are spread through several different genera and families. Since they are often studied as a group, it is convenient to call them by the informal (non-taxonomic) name of "cyphelloid fungi". Better known cyphelloid genera include Calyptella, with stalked, cup- or bell-like fruit bodies; Lachnella, with conspicuous, hairy-margined, disc-like fruit bodies; Flagelloscypha with smaller, but equally hairy, cup-like fruit bodies; Henningsomyces with tube-like fruit bodies; and Merismodes with clustered, hairy, cup-like fruit bodies.
The hydnoid fungi are a group of fungi in the Basidiomycota with basidiocarps producing spores on pendant, tooth-like or spine-like projections. They are colloquially called tooth fungi. Originally such fungi were referred to the genus Hydnum, but it is now known that not all hydnoid species are closely related.
Macrotyphula is a genus of clavarioid fungi in the family Phyllotopsidaceae. Basidiocarps are simple, narrowly club-shaped to filiform, sometimes arising from a sclerotium. They typically grow on dead wood or leaf litter, often in swarms.
Volutella is a genus of fungi belonging to the family Nectriaceae.
Mariannaea is a genus of fungi belonging to the family Nectriaceae.
Stilbella is a genus of fungi in the order Hypocreales. The relationship of this taxon to other taxa within the order is unknown, and it has not yet been placed with certainty into any family. It is sometimes placed in the family Bionectriaceae.
Microcera is a genus of Ascomycete fungi in the Nectriaceae family.
Savoryella is a genus of freshwater and marine based fungi in the family Savoryellaceae and the order Savoryellales.
