SUMMARY A key to the 48 taxa of Pythium recorded so far from the West Bank and Gaza Strip is given.isolation and preservation methods are also provided. The following species are described and illustrated: P. acanthicum Drechsler, P. anandrum Drechsler, P. aphanidermatum (Edson) Fitzp, P. coloratum Vaartaja, P. conidiophorum loki, P. debaryanum auct non Hesse, P. dissimile Vaartaja, P. dissotocum Drechsler, P. echinulatum Matthews, P. graminicola Subramaniam, P. intermedium de Bary, P. irregulare Buisman, P. iwayamqi S. Ita, P. mamillatum Meurs, P. middletonii Sparrow, P. monospermum Pringsh, P. nagaii S. Ita & Tokunga, P. oligandrum Drechsler, P. papillatum Matthews, P. paroecandrum Drechsler, P. pulchrum Minden, P. rostratum Butler, P. salpingophorum Drechsler, P. spinosum Sawada, P. splendens Braum, P. sylvaticum Campbell & Hendrix, P. torulosurn Coker & Patterson, P. ultimum var sporangiiferum Drechsler, P. ultimum Trow var ultimum, P. vantrepoolii V. Kouyeas, and P. vexans de Bary. Descriptions were produced from the study of several isolates in order to account for intraspecific variation. The other 17 taxa were outlined briefly. These taxa were isolated only once or twice and/ or failed to from sexual reproductive structures following their identification (P. deliense Meurs, P. dimorphum Hendrix & Campbell, P. hypogynum Middelton, P. myriotylum Drechsler, P. orthogonon Ahrens, P. periplocum Drechsler, P. pyrilobum Vaartaja, and P. tracheiphilum Matta), taxa without oogonia (P. group 'F', P. group 'G', P. group 'HS', and P. group 'L'), and taxa described by the author in 1982 from Britain (P. lucens, P. lutarium, p. minor, p. pachycaule, and P. parvum) and were also isolated from the West Bank. Occurence of the different taxa in the West Bank and Gaza Strip as well as in other neighbouring countries is briefly outlined. All known records of rare species are mentioned. All known host records of Pythium from the West Bank and Gaza Strip are also listed.
