Abstract A description is provided for Ploioderma hedgcockii. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Recorded from Pinus caribaea, P. clausa, P. echinata, P. palustris, P. rigida, P. tueda and P. virginiana. DISEASE: Causes needle blight of pines. The anamorph develops on green needles, and may be responsible for premature shedding (30, 131). This is substantiated in a later report (38, 629), which states that ascomata occur on green needles which turn yellowish throughout their length and are shed prematurely. Ploioderma hedgecockii was implicated in a severe outbreak of needle blight of Pinus caribaea (syn. P. elliottii) and P. tueda in the southern USA in 1970-1 (51, 1989), but was thought to be secondary in importance, the damage principally being caused by Ploioderma lethale (Dearness) Darker and Lophodermella cerina (Darker) Darker. The symptoms described in this report were different, distal portions of the leaves dying, and later becoming brown over their whole length and falling from the tree. GEOGRAPHICAL DISTRIBUTION: USA: reported from Alabama, Florida, Georgia, Louisiana, Maryland, Mississippi, North Carolina, Tennessee, Texas and Virginia. TRANSMISSION: Unknown. Needles are probably directly infected by the air-dispersed ascospores.

Abstract A description is provided for Bifusella linearis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus albicaulis, P. flexilis, P. monticola, P. strobus. DISEASE: Needle blight and needle cast of white pines, tar spot needle cast, Bifusella blight. The disease apparently occurs only under moist conditions, and since its effects are usually limited to defoliation of needles two or three years old, it is not devastating. Probably infects young needles but macrosymptoms do not show up until the following spring when needles become blighted from the tip part-way to the base. The disease tends to occur principally in the lower crown (47, 2867). GEOGRAPHICAL DISTRIBUTION: North America (Canada: British Columbia, Ontario, U.S.A. : California, Colorado, Idaho, Maine, Massachusetts, Minnesota, New Hampshire, New York, North Carolina, Pennsylvania, Washington, Wisconsin). TRANSMISSION: By air-borne ascospores in wet or humid weather.

HOSTS: Arachis hypogaea, Arachnoides adiantiformis (62, 687; 63, 4469), Arecastrum romanzoffianum, Asparagus plumosus, Callistemon spp., Cedrella vulgaris, Chamadorea elegans, Cocos nucifera, Collinia elegans, Dryopteris, Eucalyptus spp., Heliconia bihai, Howea spp., Lupinus spp., Melaleuca leucadendron (48, 609), Pinus caribaea var. hondurensis, P. oocarpa, Rhododendron obtusum, Scolopendrium sp., Solanum tuberosum (61, 4007), Strelitzia reginae, Washingtonia robusta. DISEASE: Associated with leaf spots and root disease of various hosts. Leaf spot of oil palm on the Ivory Coast (53, 1502; 59, 1835), of Camellia sinensis in Mauritius (41; 358; 53, 1669), and needle blight of Pinus caribaea (61, 6624) have been reported. GEOGRAPHICAL DISTRIBUTION: Africa, Australia, Brazil (61, 5172), India, Malaysia (53, 4211), Sabah, U.S.A. (Florida). TRANSMISSION: Probably wind and splash dispersed.

Abstract A description is provided for Hypocreopsis rhododendri, which is considered to be a superficial parasite of Hymenochaetopsis corrugata (as Hymenochaete corrugata and Pseudochaete corrugata), itself a broad-spectrum wood-rotting species most typically found associated with Corylus avellana (hence 'hazel gloves', the vernacular English name of Hypocreopsis rhododendri). Some information on its habitat, dispersal and transmission, and conservation status is given, along with details of its geographical distribution (North America (USA (Maine, Maryland, North Carolina, Tennessee, West Virginia)), Europe (France, Ireland, Russia (Moscow Oblast), Spain, UK)).

Abstract A description is provided for Amarenomyces ammophilae, usually found on attached dead leaves and stems of grasses typical of coastal sand ecosystems. Nothing is known about when it colonizes the substratum, but it is saprobic by the time conidiomata and ascomata are produced. Some information on its associated organisms and substrata, habitats, dispersal and transmission and conservation status is given, along with details of its geographical distribution (Africa (Morocco), North America (USA (Massachusetts, New York, North Carolina)), Antarctica (Macquarie Island), Australasia (New Zealand), Europe (Belgium, Denmark, Estonia, Finland, Germany, Ireland, Italy, Lithuania, Netherlands, Norway, Sweden, Ukraine, UK)).

Abstract A description is provided for Lophodermium ravenelii. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: Nothing is yet known about the ecology of this species, except that zone lines, conidiomata and ascomata occur on secondary needles of native pines. The species is included here to aid identification of, and for comparison with, other members of this genus also on pines (Lophodermium australe, IMI Descriptions No. 563; L. baculiferum, IMI Descriptions No. 795; L. canberrianum, IMI Descriptions No. 564; L. conigenum, IMI Descriptions No. 565, L. durilabrum, IMI Descriptions No. 796; L. himalayense, IMI Descriptions No. 1149; L. indianum, IMI Descriptions No. 787; L. kumaunicum, IMI Descriptions No. 786; L. nitens, IMI Descriptions No. 566; L. orientale, IMI Descriptions No. 788; L. pinastri, IMI Descriptions No. 567, L. pini-excelsae, IMI Descriptions No. 785 and L. seditiosum, IMI Descriptions No. 568), some of which are known to be pathogenic. Most probably this is another fungus which begins as an endobiont, later perhaps (and under specific conditions) causing early senescence of the needle, then fruiting on that needle after its death. HOSTS: Pinus taeda, Pinus sp. (leaves). GEOGRAPHICAL DISTRIBUTION: NORTH AMERICA: USA (North Carolina, South Carolina, Texas). TRANSMISSION: Not known. Presumably by air-borne ascospores released in humid conditions.
