Abstract. Five new species of Pythium are described, following ecological studies of the genus in the Reading (U.K.) area.
Two of the new species were found abundantly, three were rarely. The phylogeny of species and varieties of Pythium was studied using parsimony and phenetic analysis of the ITS region of the nuclear ribosomal DNA.
The D1, D2 and D3 regions of the. The genus Pythium comprises more than species but only P. insidiosum has been reported to cause disease in mammals. 38,40,41 A Lagenidium sp. recently recovered from some dogs with pythiosis-like lesions is still awaiting verification. 42 However, it is thought that these canine isolates may not belong to the Studies on the genus Pythium.
book. Pythium spe-cies are more closely related to the algae than they are to the higher fungi. There is now a large body of evidence to support this relationship.
As a result, the genus Pythium has been moved from the fungal kingdom, Mycetae, and placed into the kingdom Protoctista (See Table 1 above.). Still other studies. Pythium is a genus with over species found worldwide, some of which are residents of terrestrial habitats while others are aquatic.
In terms of nutrient acquisition, species within the genus may be saprophytes, plant or animal parasites, or mycoparasites. The genus Pythium is one of the most important groups of soilborne plant pathogens, present in almost every agricultural soil and attacking the roots of thousands of hosts, reducing crop yield and quality.
Most species are generalists, necrotrophic pathogens that infect young juvenile tissue. In fact, Cook and Veseth have called Pythium. Monograph of the genus Pythium. Abstract In this comprehensive revision, sections on material and methods, morphology and terminology, ecology, pathogenicity and microbial interactions are followed by a systematic account of the genus.
The Pythium biocontrol features of 17 Paenibacillus strains, all previously isolated from the rhizosphere, hyphosphere or bulk soil from mycorrhizal and non-mycorrhizal cucumber plants, were examined using a cucumber seedling emergence bioassay.

The genus Pythium, with slightly over described species, has been classified traditionally with other filamentous, coenocytic, sporangia-producing fungi as “Phycomyetes”.However, with recent advances in chemical, ultrastructural and molecular studies, Pythium.
The key is presented as a guide to identifying Pythium to the species level. It is a modification of that created by Anna van der Plaats-Niterink (Van der Plaats-Niterink, A.

He was a prominent eugenicist /5(1). The genus Pythium was established by Pringsheim in and placed in the family Saprolegniaceae. entophytum Pringsheim and P. monospermum Pringsheim were the first described species.
monospermum later became the type species with the transfer of P. entophytum to the genus Lagen;dium. Schroter () included Pythium. Abstract A guide to methods of isolation and preservation of Pythium is provided. A key to the 27 species of Pythium so far recorded from New Zealand is given.

Pythium species are genetically diverse and exhibit significant variation in terms of virulence, host range, and distribution.Despite being members of the Pythium lineage that produces filamentous sporangia, Pythium aphanidermatum and Pythium arrhenomanes have distinct temperature optima and levels of r to Pythium ultimum var.

The genus Pythium is a complex genus containing over described species that occupy a variety of terrestrial and aquatic ecological habitats (Dick, ).
Perhaps the most economically important members of this genus. Pythium porphyrae, is a parasitic species of oomycete in the family Pythiaceae. It is the cause of red rot disease or red wasting disease, also called akagusare (赤ぐされ) in Japanese.
The specific epithet porphyrae (πορφυρα) stems from the genus .InCouch described Pythiella (lacking Latin diagnosis), a genus seemingly combining features of several oomycete genera: Olpidiopsis, Aphanomycopsis, Pythium, Ectrogella, Achlya and Saprolegnia.
Pythiella was of further interest in that it parasitized hyphae of Pythium .Meronyms (members of "genus Pythium"): pythium (any fungus of the genus Pythium). Holonyms ("genus Pythium" is a member of): family Pythiaceae; Pythiaceae (fungi having sporangia usually .
