Name and publication
Phytophthora plurivora Jung & Burgess (2009)
Jung T and Burgess TI. 2009. Re-evaluation of Phytophthora citricola isolates from multiple woody hosts in Europe and North America reveals a new species, Phytophthora plurivora sp. nov. Persoonia 22: 95–110.
Nomenclature
from Jung and Burgess (2009)
Mycobank
Synonym: most isolates identified as Phytophthora citricola prior to 2009 are most likely P. plurivora.
Etymology
refers to the wide host range (pluri Lat = many, -vora Lat = feeding)
Typification
Type: GERMANY, Irschenberg, from root lesion of declining mature Fagus sylvatica, Feb. 2004, T. Jung, holotype MURU 433 (dried culture on V8A, Herbarium of Murdoch University, Western Australia)
Ex-type: CBS 124093 = PLU-A5
Sequences for ex-type in original manuscript: CBS 124093 = ITS rDNA FJ665225, cox1 FJ665236, β-tubulin FJ665247
Ex-type in other collections
CBS 124093 = PLU-A5 = P16840 (WPC), CPHST BL 74 (Abad)
Molecular identification
Voucher sequences for barcoding genes (ITS rDNA and COI) of the ex-type (see Molecular protocols page)
Phytophthora plurivora isolate CPHST BL 74 (= P16840 WPC) = ITS rDNA MG865568, COI MH136959

Morphological identification
Colonies and cardinal temperatures
Colony morphology is stellate on V8A and MEA, and petaloid and fluffy on PDA. Minimum growth temperature 5°C, optimum 25°C, and maximum 32.5°C.
Conditions for growth and sporulation
Sporangia are produced in water cultures (soil extract or river water) and not observed in solid media. Oogonia are formed readily in single-strain culture on CA and V8A after about 7 d.
Asexual phase
Sporangia are semipapillate, persistent, and ovoid, limoniform, or ellipsoid in shape. Sporangia with two or three papillae are common. Sporangia average 47.4 ± 7.7 x 33.5 ± 5.1 µm (overall range 27.5–80.5 x 16.7–69.6 µm). Sporangiophores usually in simple sympodia, but external proliferation can result in lax sympodia. Hyphal swellings absent; Chlamydospores absent.
Sexual phase
Homothallic. Oogonia are globose with smooth walls, average size 28.5 ± 3.3 µm (overall range 15–37.5 µm). Oospores are nearly plerotic, globose to subglobose, average size 25.9 ± 3.1 µm (14–35.8). Antheridia paragynous.
Most typical characters
Phytopthora plurivora is part of a complex that includes P. citricola, P. multivora, P. pini, P. acerina and P. pachypleura. Species in this complex have very similar morphological features.
