Abstract A description is provided for Phytophthora clandestina. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Trifolium subterraneum. DISEASE: Root rot of subterranean clover; a facultatively necrotrophic plant pathogen. In field plants, black necrotic lesions develop 1-4 cm below the soil surface extending into the stele and causing orange-brown to brown tissue discoloration. Dry matter can be reduced by 71% (69, 5030). GEOGRAPHICAL DISTRIBUTION: Australasia & Oceania; Australia (NSW, WA, Vic.) TRANSMISSION: Presumably by zoospores released in moist soil. Oospores may act as perennating structures.

Abstract A description is provided for Micronectriella nivalis[Monographella nivalis]. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: The fungus is a serious pathogen of cereals (barley, wheat, rye) and grasses, especially in temperate regions where it may cause total loss of winter sown wheat and rye (43, 1873; 48, 3456). Tropical records, especially those on rice, need to be confirmed. DISEASE: Pre-emergence blight, root rot and occasionally head blight of cereals. Snow mould of turf. GEOGRAPHICAL DISTRIBUTION: Europe, extremely widespread, USSR, Japan, Australia, New Zealand, N.E. and N.W. USA and Canada. Records have also been cited of its occurrence in India and West Africa (CMI Map 432, ed. 1, 1967). TRANSMISSION: By seed, soil, water and in summer by aerial dissemination of ascospores (48, 1628).

HOSTS: On Coniferae, including Araucaria, Cedrus, Chamaecyparis, Cryptomeria, Cupressocyparis, Cupressus, Dacrydium, Ginkgo, Juniperus, Libocedrus, Pinus, Pseudotsuga and Thuja. DISEASE: Leaf and stem blight, occasionally canker or girdling, dieback and root-rot. GEOGRAPHICAL DISTRIBUTION: Europe (UK, Italy, Romania, Spain, Netherlands, Belgium); Africa (S. Africa, Kenya, Rhodesia, Tanzania, Zaire, Zambia); Asia (USSR, Japan); Australasia (Australia, New Zealand); America (Canada, Ecuador, USA, Bermuda). TRANSMISSION: Has been found in seed samples (35, 643) and isolated from soil, but no detailed studies have been reported.

Abstract A description is provided for Mycocentrospora acerina. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: A very wide host range (29, 364); parsley, celery, carrot and parsnip are among the most important economically. DISEASE: Pansy leaf spot; celery storage rot; root rot, canker and black crown rot of parsnip; liquorice rot of carrot. GEOGRAPHICAL DISTRIBUTION: Europe (UK, Ireland, Germany, Czechoslovakia, Netherlands, Poland, Rumania, USSR, Denmark); N. America (USA, Canada); Australia, New Zealand. TRANSMISSION By splash dispersed conidia; these are viable for short periods only (26, 133). Survival for longer periods is by infected debris and chlamydospores in the soil (23, 324; 45, 681; 52, 899). Water-borne spread is possible (49, 1526) and transmission on pansy seeds has been demonstrated (51, 422).

Abstract A description is provided for Pythium tracheiphilum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Lactuca saliva, Spinacea oleracea. DISEASE: Vascular wilt and stem rot of lettuce; a facultatively necrotrophic plant pathogen. Symptoms are severe stunting and wilting of young or maturing plants, vascular browning and necrotic leaf lesions, which may be large or small and restricted (58, 2495). GEOGRAPHICAL DISTRIBUTION: Europe; Germany, Italy, Netherlands, Sweden, UK (England). North America: USA (WI). TRANSMISSION: Presumably by zoospores in moist soil and by rapid mycelial growth. Oospores and resting spores probably act as perennating structures.
