David Norman Pegler
David Norman Pegler (born 2 November 1938) is a British mycologist who spent his entire professional career at Kew Gardens, where he became Head of Mycology and assistant keeper of the herbarium. A leading authority on tropical agarics, he described 11 new genera and over 180 species of fungi during expeditions to regions including East Africa, the Caribbean, and South America. He authored more than 200 scholarly articles and 35 books on fungal systematicswhilst also producing popular field guides, and received the Distinguished Mycologist Award from the Mycological Society of America upon his retirement in 1998. His contributions to mycology have been honoured with several species named after him and with two fungal genera, '' Pegleromyces'' and '' Peglerochaete''. Early life and education Pegler developed an interest in natural history during his childhood, joining natural history societies and bird-watching groups. This led to his fascination with fungi, which eventually shap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycologist
Mycology is the branch of biology concerned with the study of fungi, including their taxonomy, genetics, biochemical properties, and use by humans. Fungi can be a source of tinder, food, traditional medicine, as well as entheogens, poison, and 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 Ancient Greek: μύκης (''mukēs''), meaning "fungus" and the suffix (''-logia''), meaning "study." Pioneer mycologists included Elias Magnus Fries, Christiaan Hendrik Persoon, Heinrich Anton de Bary, Elizabeth Eaton Morse, and Lewis David de Schweinitz. Beatrix Potter, author of '' The Tale of Peter Rabbit'', also made signific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Agaricaceae
The Agaricaceae are a family of basidiomycete fungi and include the genus ''Agaricus'', as well as basidiomycetes previously classified in the families Tulostomataceae, Lepiotaceae, and Lycoperdaceae. Taxonomy The family Agaricaceae was published by French botanist François Fulgis Chevallier in 1826. It is named after the type genus ''Agaricus'', originally circumscribed by Carl Linnaeus in his 1753 work ''Species Plantarum''. In his authoritative 1986 classification of the Agaricales, Rolf Singer divided the Agaricaceae into four tribes distinguished largely by spore color: ''Leucocoprineae'', ''Agariceae'', ''Lepioteae'', and ''Cystodermateae''. Genera once classified in the families Tulostomataceae, Battarreaceae, Lycoperdaceae, and Mycenastraceae have since been moved to the Agaricaceae based on molecular phylogenetics studies. According to a standard reference text, the Agaricaceae contains 85 genera and 1340 species. Description Agaricaceae species use a wide variety of ...

Paxillaceae
The Paxillaceae are a family of mushroom-forming fungi bearing close affinity to the boletes. Collectively, the family contains nine genera and 78 species. The type genus is ''Paxillus'', containing fungi with decurrent gills, and '' Gyrodon'', which has members with decurrent pores, among others. French mycologist René Maire had erected the family in 1902, placing it between the agarics and boletes and recognizing the groups' similarities with the latter group. Maire's usage of the name was later deemed to be invalid, and the genus authority is attributed to Johannes Paulus Lotsy. Molecular research confirms the relations of ''Gyrodon'', with the decurrent-pored mushroom '' G. lividus'', ''Paragyrodon'', with the type species ''P. sphaerosporus'', and ''Paxillus'' as sister groups, together lying near the base of a phylogenetic tree from which the genus ''Boletus'' arises. The name Gyrodontaceae, published by Belgian botanist Paul Heinemann in 1951, is considered syn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amanitaceae
The Amanitaceae is a family of mushroom-forming fungi. ''Amanita'' Pers. is one of the most speciose and best-known fungal genera. The family, also commonly called the amanita family, is in order Agaricales, the gilled mushrooms. The family consists primarily of the large genus ''Amanita'', but also includes the smaller genera '' Catatrama'', '' Limacella'', '' Limacellopsis'', '' Saproamanita'', and '' Zhuliangomyces''. The species are usually found in woodlands. The most characteristic emerge from an egg-like structure formed by the universal veil. This family contains several species valued for edibility and flavor, and other deadly poisonous ones. More than half the cases of mushroom poisoning stem from members of this family. The most toxic members of this group have names that warn of the poisonous nature, but others, of varying degrees of toxicity, do not. Some notable species * ''Amanita caesarea'', Caesar's mushroom * ''Amanita muscaria'', fly agaric * ''Amanita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boletaceae
The Boletaceae are a Family (biology), family of mushroom-forming fungi, primarily characterised by small pores on the spore-bearing hymenium, hymenial surface (at the underside of the mushroom), instead of Lamella (mycology), gills as are found in most agarics. Nearly as widely distributed as the agarics, the family is renowned for hosting some prime edible species highly sought after by mushroom hunting, mushroom hunters worldwide, such as the Boletus edulis, cep or king bolete (''Boletus edulis''). A number of rare or threatened species are also present in the family, that have become the focus of increasing conservation biology, conservation concerns. As a whole, the typical members of the family are commonly known as boletes. Boletes are a group of mushrooms reasonably safe for human consumption, as none of them are known to be deadly to adults. Edible bolete species are especially suitable for novice collectors, since they pose little danger of being confused with deadly p ...
