“…The complex of fungi associated with spruce beetle was dominated by L. abietinum (Tables 1 and 5), consistent with other studies (Davidson, 1955;Hinds and Buffam, 1971;Ohsawa et al, 2000;Six and Bentz, 2003). This domination of the flora of its vector differs from L. abietinum's association with the Douglas-fir beetle D. pseudotsugae Hopkins, from which O. pseudotsugae (Rumbold) von Arx is also a frequent associate (Harrington, 1988;Lewinsohn et al, 1994;Ross and Solheim, 1997;Solheim and Krokene, 1998).…”

“…(Six and Bentz, 2003), or C. rufipenni (Davidson, 1955;Hinds and Buffam, 1971;Safranyik et al, 1983), which have been observed in some D. rufipennis populations. C. rufipenni is highly virulent (Solheim and Safranyik, 1997), but appears primarily localized in British Columbia (Safranyik et al, 1983), sporadically in Alberta (Ohsawa et al, 2000) and possibly in Colorado (Davidson, 1955) (if the C. coerulescens forms isolated by Davidson included C. rufipenni;Wingfield et al, 1997). Our results concur with previous studies that did not locate C. rufipenni in the Kenai Peninsula of Alaska (Reynolds, 1992;Six and Bentz, 2003), Colorado and Utah (Six and Bentz, 2003), Minnesota (Haberkern et al, 2002;Six and Bentz, 2003), Wisconsin and Michigan (Haberkern et al, 2002).…”

“…However, spruce beetles are commonly associated with a variety of fungi, predominantly Leptographium abietinum (Peck) Wingfield, but also Ceratocystis coerulescens (Munch) Baski (Reynolds, 1992;Six and Bentz, 2003) (Davidson, 1954(Davidson, , 1955Hinds and Buffam, 1971;Ohsawa et al, 2000). Recent work on the C. coerulescens complex has identified multiple taxa (Wingfield et al, 1997), including C. rufipenni Wingfield, Harrington, and Solheim, which occurs in certain areas (Solheim and Safranyik, 1997;Ohsawa et al, 2000).…”

From Ontario hardwoods and conifers, 234 collections were examined for Ceratocystis and associated stains and vectors. Most previously described species, including many type specimens, were also studied.Among morphological characters used to separate species of Ceratocystis, those of the ascospores are the most reliable and are stressed in this study. Three-dimensional examination of ascospores, particularly in species possessing spores with sheaths, is necessary to determine spore shape accurately. Four ascospore sheath types are recognized: uniform, hat-shaped, double-brimmed, and quadrangular.A preliminary survey indicates that the bark-beetles Ips pini (Say) and Orthotomicus caelatus (Eich.) may be principal vectors for several Ceratocystis spp. on Ontario conifers.Based mainly on ascospore characters, a key to 60 species of Ceratocystis is provided. The species C. galeiformis Bakshi, C. obscura (Davids.) Hunt, C. polonica (Siem.) Hunt, and C. serpens (Goid.) C. Moreau are excluded. It is proposed that C. ambrosia Bakshi, C. capillifera (Hedgc.) C. Moreau, C. pluriannulata (Hedgc.) C. Moreau, and C. schrenkiana (Hedge.) C. Moreau be considered synonyms of C. pilifera (Fr.) C. Moreau and that C. vesca Davids. be treated as a synonym of C. olivacea (Math.) Hunt. The following species, described since Hunt's key was published, are included: C. bicolor (Davids, and Wells) Davids., C. brevicollis Davids., C. brunnea Davids., C. brunneocrinita Wright and Cain, C. dryocoetidis Kendrick and Molnar, C. europhioides Wright and Cain, C. falcata Wright and Cain, C. huntii Robinson, C. megalobrunnea Davids, and Toole, C. nigra Davids., C. perfecta Davids., C. tremuloaurea Davids, and Hinds, C. truncicola (Davids.) Griffin comb. nov. Eleven new species are described in this paper.Descriptions, figures, and distribution data are provided for most of the 32 species of Ceratocystis encountered in Ontario. The following previously described species were collected: C. bicolor (Davids. and Wells) Davids., C. brunneocrinita Wright and Cain, C. coerulescens (Munch) Bakshi, C. europhioides Wright and Cain, C.fimbriata Ell. and Halst., C. huntii Robinson, C. ips (Rumb.) C. Moreau, C. major (Van Beyma) C. Moreau, C. minor (Hedgc.) Hunt, C. minuta (Siem.) Hunt, C. nigra Davids., C. olivacea (Math.) Hunt, C. perparvispora Hunt, C. piceae (Munch) Bakshi, C. pilifera (Fr.) C. Moreau, C. sagmatospora Wright and Cain, C. stenoceras (Robak) C. Moreau, C. tenella Davids., C. tetropii (Math.) Hunt, C. truncicola (Davids.) Griffin comb, nov., and C. ulmi (Buism.) C. Moreau.The following new species are described by the author: C. acericola, C. allantospora, C. angusticollis, C. capitata, C. crassivaginata, C. dolominuta, C. magnifica, C. ochracea, C. pallida, C. spinulosa, and C. stenospora.

Ophiostoma bicolor is a pathogen fungus associated with bark beetles that can cause serious damage to host plants. In this study, a novel fungal virus "Ophiostoma bicolor endornavirus 1" (ObEV1) was obtained from O. bicolor, and its complete genome sequence was determined. ObEV1 has a singlestranded positive-sense (+ss) RNA genome of 10119 nucleotides, Sequence annotation and comparison showed that the viral genome has a single large open reading frame (ORF) encoding a polyprotein of 362.48 kDa. The polyprotein contains seven conserved domains: RNA dependent RNA polymerase (RdRp), Viral RNA Helicase 1 (VHel1), Viral-methyltransferase (VMet), DEAD-like helicases (DEXDc), gliding-GltJ (G1), large tegument protein UL36 (PHA) and YlqF-related-GTPase (Y). Sequence comparisons and phylogenetic analysis showed that ObEV1 is a novel mycovirus belonging to the Betaendornavirus of "Endornaviridae" family. This is the first report of mycovirus in O. bicolor of Ophiostomatoid fungi.
