J. E. M. Mordue

Abstract A description is provided for Sphacelotheca hydropiperis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Polygonum hydropiper and many other species of Polygonum, mainly in section Persicaria. DISEASE: Flower smut of Polygonum. Infection is systemic. Hyphae in the flower stalk grow through the funicle into the ovule, from which the sorus develops leaving the perianth and stamens unchanged. Infected plants cannot normally set seed, but occasionally a portion of the inflorescence remains uninfected and some seed develops. GEOGRAPHICAL DISTRIBUTION: Widespread. Africa: Ethiopia; Asia: China, India, Indonesia, Japan, Nepal, Pakistan, Philippines, Sri Lanka, Taiwan, USSR (Central Asia, Turkestan); Australasia and Oceania: Australia, New Zealand, Papua New Guinea; Europe: Austria, Czechoslovakia, Denmark, Finland, France, Germany, Hungary, Iceland, Italy, Norway, Poland, Romania, Sweden, Switzerland, UK, USSR, Yugoslavia; North America: Canada (Newfoundland, NT, Nova Scotia, Ontario, Quebec); Greenland; Mexico; USA (Arkansas, California, Colorado, Connecticut, Delaware, Illinois, ME, Maine, Michigan, Montana, Missouri, Nebraska, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oregon, Pennsylvania, Rhode Island, Tennessee, Vermont, Virginia, Washington State, Wisconsin, Wyoming); South America: Argentina, Brazil, Chile, Colombia, Ecuador (33: 450 & 634). TRANSMISSION: Ustilospores dispersed by wind and water contaminate seed and soil and eventually germinate and infect new season's growth.

Nearctic species of the genus Geostiba Thomson, 1858 are revised. Redescription and illustrations are provided for distinguishing the genus Geostiba from other aleocharine genera. Six new species of Geostiba are described (G. (Sibiota) crepusculigena Gusarov, sp. n. from Tennessee, G. (S.) pluvigena Gusarov, sp. n. from North Carolina, G. (S.) coeligena Gusarov, sp. n. and G. (S.) nebuligena Gusarov, sp. n. from Tennessee and North Carolina, G. (S.) appalachigena Gusarov, sp. n. from West Virginia, Virginia, Maryland, Pennsylvania, New Jersey, New York, Massachusetts, Rhode Island, New Hampshire, Maine, Wisconsin and Québec; G. (S.) silvigena Gusarov, sp. n. from California). Nine species are redescribed (G. (S.) alticola Lohse & Smetana, 1988, G. (S.) balsamensis Pace, 1997, G. (S.) bicarinata Lohse & Smetana, 1988, G. (S.) graveyardensis Pace, 1997 and G. (S.) nubigena Lohse & Smetana, 1988 known from North Carolina, G. (S.) carteriensis Pace, 1997 and G. (S.) nimbicola Lohse & Smetana, 1988 known from Tennessee and North Carolina, G. (S.) impressula (Casey, 1906) known from Oregon, and G. (s. str.) circellaris (Gravenhorst, 1806) introduced from Europe to Newfoundland). A key for identification of Nearctic species of Geostiba is provided. Geostiba impressula (Casey, 1906) is removed from synonymy with G. circellaris. Ditroposipalia Scheerpeltz, 1951 is placed in synonymy with Sibiota Casey, 1906 (a valid subgenus of Geostiba), Geostiba fossata (Casey, 1910) with G. impressula (Casey, 1906), Sipaliella Casey, 1911 with Meotica Mulsant & Rey, 1873 (a valid genus in tribe Oxypodini) and Sipalia (Sipaliella) filaria Casey, 1911 with Meotica pallens (Redtenbacher, 1849). Tylosipalia Scheerpeltz, 1951 is confirmed to be a synonym of Typhlusida Casey, 1906 (a valid subgenus of Geostiba). The lectotype of Sipalia fossata Casey, 1906 is designated. The geographical distribution of Geostiba in the Southern Appalachians is discussed.

Abstract A description is provided for Coccomyces strobi. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus ayacahuite, P. excelsa [= P. wallichiana] (twig), P. monticola (twig), P. strobus (twig), P. wallichiana. Most records are on P. strobus. DISEASE: Coccomyces strobi is found on recently killed twigs of 5-needle pines. Sherwood (60, 1319) noted that 'since the fungus is nearly ubiquitous and appears soon after the death of the portions of the host on which it occurs, it is tempting to brand it as parasitic'. The twigs on which it occurs are typically rather brittle, suggesting that, like Therrya fuckelii (IMI Description 1297), T. pini (IMI Description 1298) and Colpoma quercinum (IMI Description 942), this fungus may have a rôle in self-pruning of the tree. GEOGRAPHICAL DISTRIBUTION: Canada (British Columbia, New Brunswick, Nova Scotia, Ontario), Hungary, Ukraine, USA (Connecticut, Georgia, Maine, Maryland, Massachusetts, Michigan, Minnesota, Nebraska, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Virginia, Washington, Wisconsin). European records are on Pinus strobus, a native of North America. The fungus is thus most probably also to be a native of North America, which has travelled to Europe with its host. The record from Ukraine is tentative, based on a collection with rather old ascomata. The record from Washington State on P. monticola appears to be the first from west of the Rockies. TRANSMISSION: By air-borne ascospores in humid conditions; in the USA, ascomata containing ascospores have been observed from May to August.
