Abstract A description is provided for Ustilago hypodytes. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: A wide range of grasses, including species of Agropyron (many), Ammophila, Brachypodium, Bromus, Calamagrostis, Diplachne, Distichlis, Elymus (many), Festuca, Glyceria, Hilaria, Hordeum, Haynaldia, Lygeum, Melica, Orysopsis, Panicum, Phalaris, Phleum, Poa (many), Puccinellia, Secale, Sitanion, Sporobolus, Stipa (many), and Trisetum. DISEASE: Stem smut of grasses. GEOGRAPHICAL DISTRIBUTION: Chiefly a temperate species found in Europe (including Denmark, Finland, France, Germany, Hungary, Italy, Romania, Sweden, Switzerland, UK, USSR, Yugoslavia) and North America (Canada, USA) and extending to central and South America (Argentina, Peru, Uruguay), N. Africa (Libya, Morocco, Tunisia), Japan, Australia and New Zealand. TRANSMISSION: Not fully understood, though inoculation experiments have demonstrated that infection occurs in mature vegetative plants (possibly through meristematic tissue), not seeds or flowers (22, 240; 24, 511). Once established, infection is systemic, probably overwintering in the root system and spreading by vegetative multiplication of host plants as well as from plant to plant (24, 511; 19, 720).

Abstract A description is provided for Ophioceras leptosporum. Some information on its associated organisms and substrata, dispersal and transmission, habitats and conservation status is given, along with details of its geographical distribution (Africa (Cameroon), North America (Mexico), South America (Brazil (Bahia)), Asia (Afghanistan, China (Hong Kong), Malaysia, Papua New-Guinea, Taiwan, Thailand), Australasia (New Zealand), Europe (Belgium, Finland, Netherlands, Serbia, Spain, Switzerland, UK)). In a study of endophytes of Terminalia and other plants in Cameroon, Toghueo et al. (2017) detected O. leptosporum and demonstrated that it produced amylase and lipase, both enzymes with potential economic applications.

Abstract A description is provided for Phytophthora cryptogea. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On a wide range of glasshouse and field crops. Tomato, ornamentals (including petunia, aster, chrysanthemum, Tagetes, tulip, wallflower, Gerbera, gloxinia, Matthiola, Papaver, cineraria, dahlia, Gypsophila, Hebe, Rhododendron, Osteospermum, zinnia), potato, chicory, spinach, bean, onion, cucurbits, eggplant, hop, sunflower, safflower, lucerne, Cupressus, Chamaecyparis, chestnut and others. DISEASE: Damping-off and foot rot of tomato; foot rots of aster, Matthiola and Gerbera; black neck of chrysanthemum; tulip shanking; corm, stem and leaf rot of gloxinia; crown rot of Iceland poppy; pink rot of potato; sunflower stem rot; chestnut wilt; damping-off, root rots and wilts of many other hosts. GEOGRAPHICAL DISTRIBUTION: Europe (UK, Irish Republic, Austria, Czechoslovakia, Denmark, France, Germany, Greece, Italy, Netherlands); Africa (Egypt, Rhodesia); Asia (Iran); Australia; New Zealand; N. America (Canada, USA). (CMI Map 99, ed. 4, 1976). TRANSMISSION: Soil-borne, persisting for several years (6, 669). Tulip bulbs were invaded from the soil (18, 183). Movement of zoospores was studied (56, 1029). Isolates were obtained from glasshouse water supplies (1, 94). There was a high frequency of recovery on baiting irrigation water in Victoria (57, 2174).

Abstract A description is provided for Entyloma calendulae f. dahliae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Dahlia variabilis, D. coccinia, D. pinnata; cultivated dahlia. DISEASE: Leaf spot of Dahlia. GEOGRAPHICAL DISTRIBUTION: Widely distributed in Europe including Finland and Sweden; Africa; North America (USA); Central and South America and West Indies (Argentina, Brazil, Colombia, El Salvador, Guatemala, Jamaica, Venezuela); Asia (Burma, India, Indonesia, Israel, Japan, Malaysia, Nepal, Pakistan, Sri Lanka, Papua New Guinea); Australia and New Zealand. CMI Map 114, ed. 4, 1983. TRANSMISSION: Soil-borne. Overwinters as ustilospores buried in plant debris; not transmitted by seed or in tubers, although spread by soil attached to tubers is possible (6, 97; 17, 655; 41, 603; 49, 1050); mature ustilospores are capable of remaining viable for a long period when dry (16, 304). Conidia contribute to dissemination during the growing season (49, 1050).

Abstract A description is provided for Fusarium flocciferum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Isolated from soil. Also occurs on the roots of a wide range of plants, including temperate cereals (Hordeum, Triticum), legumes (Lupinus, Pisum, Vicia), cucurbits (Cucumis sativus), and others such as carrot (Daucus carota) and beet (Beta vulgaris); sometimes occurs in association with nematodes. DISEASE: Not regarded as an aggressive pathogen, but in association with nematodes may cause root lesions, damping-off, root, tuber or bulb rots. Reported to cause disorders of cultivated mushroom beds. Occasionally causes skin infections of animals (one IMI record from crocodile's tail). GEOGRAPHICAL DISTRIBUTION: Widespread but infrequent, apparently more common in temperate regions. Reported from Asia: Bhutan, China, India, Iran, Turkey; Australasia: New Zealand; Europe: Denmark, Germany, The Netherlands, Poland, Turkey (W), UK; North America: Canada, USA. TRANSMISSION: Conidia are dispersed locally by water flow and splash droplets. Chlamydospores may be transported by movement of soil or infected plant debris. It may also be seed-borne (71, 1568).
