Taphrina Communis
''Taphrina'' is a fungus, fungal genus within the Ascomycota that causes leaf and catkin curl diseases and witch's brooms of certain flowering plants. One of the more commonly observed species causes peach leaf curl. ''Taphrina'' typically grow as yeasts during one phase of their biological life cycle, life cycles, then infect plant tissues in which typical hyphae are formed, and ultimately they form a naked layer of Ascus, asci on the deformed, often brightly pigmented surfaces of their hosts. No discrete fruit body is formed outside of the gall-like or blister-like tissues of the hosts. The asci form a layer lacking paraphyses, and they lack crozier (mycology), croziers. The ascospores frequently bud into multiple yeast cells within the asci. Phylogenetically, ''Taphrina'' is a member of a basal (phylogenetics), basal group within the Ascomycota, and type genus for the subphylum Taphrinomycotina, the class Taphrinomycetes, and order Taphrinales.

Elias Magnus Fries
Elias Magnus Fries (15 August 1794 – 8 February 1878) was a Swedish mycologist and botanist. He is sometimes called the Mycology, "Linnaeus of Mycology". In his works he described and assigned botanical names to hundreds of fungus and lichen species, many of which remain authoritative today. Career Fries was born at Femsjö (Hylte Municipality), Småland, the son of the pastor there. He attended school in Växjö. He acquired an extensive knowledge of flowering plants from his father. In 1811 Fries entered Lund University where he studied under Carl Adolph Agardh and Anders Jahan Retzius. He obtained his doctorate in 1814. In the same year he was appointed an associate professorship in botany. Fries edited several exsiccata series, the first starting in 1818 under the title ''Lichenes Sveciae exsiccati, curante Elia Fries'' and the last together with Franz Joseph Lagger under the title ''Hieracia europaea exsiccata''. He was elected a member of the Royal Swedish Academ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paraphyses
Paraphyses are erect sterile filament-like support structures occurring among the reproductive apparatuses of fungi, ferns, bryophytes and some thallophytes. The singular form of the word is paraphysis. In certain fungi, they are part of the fertile spore-bearing layer. More specifically, paraphyses are sterile filamentous hyphal end cells composing part of the hymenium of Ascomycota and Basidiomycota interspersed among either the asci or basidia respectively, and not sufficiently differentiated to be called cystidia A cystidium (: cystidia) is a relatively large cell found on the sporocarp of a basidiomycete (for example, on the surface of a mushroom gill), often between clusters of basidia. Since cystidia have highly varied and distinct shapes that are o ..., which are specialized, swollen, often protruding cells. The tips of paraphyses may contain the pigments which colour the hymenium. In ferns and mosses, they are filament-like structures that are found on sporangi ...

Taphrina Caerulescens
''Taphrina caerulescens'' is a species of fungus in the family Taphrinaceae. It is a pathogenic Ascomycete fungus that causes oak leaf blister disease on various species of oak trees (''Quercus'' spp.). The associated anamorph species is ''Lalaria coccinea'', described in 1990. This disease causes lesions and blisters on Oak leaves. Effects of the disease are mostly cosmetic. Although not taxonomically defined, strains of ''T. caerulescens'' have been shown to be host specific with varying ¬ascus morphology between strains. There are differences in strains' abilities to metabolize various carbon and nitrogen compounds. This has been proposed as a method of taxonomically defining subspecies within ''T. caerulescens''.Mix, A., J. 1954. Differentiation of species of Taphrina in culture.

Taphrina Betulina
''Taphrina betulina'' is a fungal plant pathogen that causes the gall, witches broom, which is a chemical infection of birch buds or the developing shoots, leading to a proliferation of growth. It was first described by Emil Rostrup in 1883 and is found in Europe, New Zealand and North America. Description Witches broom on birch trees (''Betula'' species), are dense bunches of stunted twigs which look like birds nests. The gall starts as densely packed clusters of buds which can remain for many years. Possibly, when the fungus loses vigour, the buds grow into many slender shoots. In the spring, asci form on small leaves which grow on the shoots. These leaves usually fall before the normal leaves grow elsewhere on the tree. There can be several witches broom in a tree. Witches broom, formed by ''Taphrina betulina'' can be found on dwarf birch (''Betula nana''), '' Betula nana x pubescens'', silver birch (''Betula pendula''), downy birch (''Betula pubescens'') and ''Betula pube ...

Taphrina Alni
''Taphrina alni'' is a fungal plant pathogen that causes alder tongue gall, a chemically induced distortion of female alder catkins (''Alnus glutinosa'').Ellis, Hewett A. (2001). ''Cecidology''. Vol.16, No.1. p. 24. ''Taphrina alni'' produces a distinctive tongue-like growth which derives mainly from the ovarian tissues of the alder catkin or from the bracteoles. These alder pseudocones may carry several tongue galls, each of which usually appear to come from the same position; those curling down usually come from the bracteoles tissues and those projecting upwards usually come from ovarian tissues.Ellis, Hewett A. (2001). ''Cecidology''. Vol.16, No.1. p. 28. Distribution This gall was rare in the United Kingdom and is absent from many of the published gall keys, although common in Western Europe. It was recorded first in Cornwall first in the 1930s, and then in Northumberland, Ayrshire and Skye, mainly since the 1990s. It is becoming quite common throughout the United Ki ...

Taphrinomycotina
The Taphrinomycotina are one of three subdivisions constituting the Ascomycota (fungi that form their spores in a sac-like ascus) and is more or less synonymous with the slightly older invalid name Archiascomycetes (sometimes spelled Archaeascomycetes; archea = ancient). Recent molecular studies suggest that the group is monophyletic and basal to the rest of the Ascomycota. The major taxa are Schizosaccharomycetes, Taphrinomycetes, Neolectomycetes, and Pneumocystis. The Schizosaccharomycetes are the yeasts (e.g. '' Schizosaccharomyces'') that reproduce by fission rather than budding, unlike most other yeasts, many of which are in the subdivision Saccharomycotina. The Taphrinomycetes are dimorphic plant parasites (e.g. '' Taphrina'') with both a yeast state and a filamentous ( hyphal) state in infected plants. They characteristically infect leaves, catkins, and branches, not roots. Taphrinomycetes form asci but no ascomata. The Neolectomycetes are species in a single genus, ' ...
