Amaropostia Stiptica
''Amaropostia stiptica'' is a rare, bitter-tasting species of polypore fungus in the family Fomitopsidaceae. It is known for being one of the most bitter-tasting substances ever tested, surpassing denatonium benzoate in sensory assays. This fungus forms woody, shelf-like fruiting bodies and typically grows on dead or decaying hardwood in tropical and subtropical forests. Description ''Amaropostia stiptica'' produces perennial, sessile, bracket-like fruiting bodies that are hard and woody. The upper surface is typically greyish to brownish and concentrically zoned, while the underside features fine pores. The taste is extraordinarily bitter and immediate, reportedly unbearable in sensory evaluations. Chemistry and bitterness According to a 2025 study, ''A. stiptica'' contains multiple secondary metabolites such as Oligoporin D that activate human bitter taste receptors TAS2R14 and TAS2R46 with remarkable potency. These compounds elicit responses up to 10 times greater than de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polypore
Polypores, also called bracket or shelf fungi, are a morphological group of basidiomycete-like gilled mushrooms and hydnoid fungi that form large fruiting bodies called conks, which are typically woody, circular, shelf- or bracket-shaped, with pores or tubes on the underside. Conks lie in a close planar grouping of separate or interconnected horizontal rows. Brackets can range from only a single row of a few caps, to dozens of rows of caps that can weigh several hundred pounds. They are mainly found on trees (living and dead) and coarse woody debris, and may resemble mushrooms. Some form annual fruiting bodies while others are perennial and grow larger year after year. Bracket fungi are typically tough and sturdy and produce their spores, called basidiospores, within the pores that typically make up the undersurface. Most polypores inhabit tree trunks or branches consuming the wood, but some soil-inhabiting species form mycorrhiza with trees. Polypores and the related co ...

Fomitopsidaceae
The Fomitopsidaceae are a family (biology), family of fungi in the order Polyporales. Most species are parasitic on woody plants, and tend to cause Wood-decay fungus#Brown rot, brown rots. The name comes from ''Fomitopsis'' (meaning "looking like Fomes") + ''-aceae'' (a suffix used to form taxonomic family names). Genera In a proposed family-level classification of the Polyporales based on molecular phylogenetics, Alfredo Justo and colleagues accept 14 genera in the Fomitopsidaceae: ''Anthoporia'', ''Antrodia'', ''Buglossoporus'', ''Cartilosoma'', ''Daedalea'', ''Fomitopsis'', ''Fragifomes'', ''Melanoporia'', ''Neolentiporus'', ''Niveoporofomes'', ''Rhodofomes'', ''Rhodofomitopsis'', ''Rubellofomes'', and ''Ungulidaedalea''.

Oligoporin D
Oligoporin D is a natural product isolated from the "bitter bracket" mushroom '' Amaropostia stiptica''. It was found to be one of the most potent agonists yet discovered for the bitter taste The gustatory system or sense of taste is the sensory system that is partially responsible for the perception of taste. Taste is the perception stimulated when a substance in the mouth reacts chemically with taste receptor cells located on tas ... receptor TAS2R46, and consequently one of the most bitter substances known.

Fomitopsis
''Fomitopsis'' is a genus of more than 40 species of bracket fungi in the family Fomitopsidaceae. Taxonomy The genus was circumscribed by Finnish mycologist Petter Karsten in 1881 with '' Fomitopsis pinicola'' as the type species. Molecular analysis indicates that ''Fomitopsis'' belongs to the antrodia clade, which contains about 70 percent of brown-rot fungi. Other genera that join ''Fomitopsis'' in the core antrodia group include '' Amyloporia'', '' Antrodia'', '' Daedalea'', '' Melanoporia'', '' Piptoporus'', and '' Rhodonia''. Studies have indicated that ''Fomitopsis'' and ''Piptoporus'' were phylogenetically heterogenous, and the type of that genus, ''Piptoporus betulinus'', is in the ''Fomitopsis'' core group. This fungus, well known for its use by Ötzi the Iceman, was transferred to ''Fomitopsis'' in 2016. The whole genome sequence of '' Fomitopsis palustris'' was reported in 2017. The generic name combines the name '' Fomes'' with the Ancient Greek word ("appearance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycology
Mycology is the branch of biology concerned with the study of fungus, fungi, including their Taxonomy (biology), taxonomy, genetics, biochemistry, biochemical properties, and ethnomycology, use by humans. Fungi can be a source of tinder, Edible mushroom, food, traditional medicine, as well as entheogens, poison, and fungal infection, infection. Yeasts are among the most heavily utilized members of the fungus kingdom, particularly in food manufacturing. Mycology branches into the field of phytopathology, the study of plant diseases. The two disciplines are closely related, because the vast majority of plant pathogens are fungi. A biologist specializing in mycology is called a mycologist. Overview The word ''mycology'' comes from the Greek language, Ancient Greek: wikt:μύκης, μύκης (''mukēs''), meaning "fungus" and the suffix (''-logia''), meaning "study." Pioneer mycologists included Elias Magnus Fries, Christiaan Hendrik Persoon, Heinrich Anton de Bary, Elizabeth E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi Described In 1853
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as one of the traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true fungi'' or ''Eumycetes ...
