Correspondence of Isozyme Characterization with Morphology in the Asexual Genus Leptographium and Taxonomic Implications

Phylogeny and taxonomy of species in theGrosmannia serpenscomplex

“…4). Our results thus suggest that a more accurate position for delineating species would be around 0.9 on the x axis in the dendrogram presented by Zambino and Harrington (1992). This also would reflect more accurately the cut-off for species in the G. clavigera complex further down on their cladogram as delimited in several multigene and population studies (Alamouti et al 2011, Lee et al 2005, Roe et al 2010, Six et al 2011.…”

“…This strongly implies a European origin for the South African fungus. USA isolates of G. alacris were from P. strobus in Virginia (Lackner and Alexander 1983) and P. taeda in Mississippi (Zambino and Harrington 1992). There are various root-feeding bark beetles native to USA that carry Grosmannia, so the fungus could be native in that country.…”

Leptographium tereforme sp. nov. and other Ophiostomatales isolated from the root-feeding bark beetle Hylurgus ligniperda in California

“…It is generally considered a secondary pest because it does not aggressively kill trees (Haack 2006), although it may become lethal when the trees are stressed or injured (Neumann 1987). The beetle may cause minor economic damage by introducing sapstain fungi to wood (Harrington 1988, Zhou et al 2004a, and it could become an effective vector of a tree pathogen or blue-stain fungus (Harrington 1988(Harrington , 1993(Harrington , 2005Jacobs and Wingfield 2001;Paine et al 1997;Six 2003).…”

“…Ophiostomatales have been isolated from H. ligniperda collected in South Africa (Zhou et al 2001), Chile (Zhou et al 2004a), New Zealand (Reay et al 2006) and Spain (Romó n et al 2007). Zhou et al (2001) Flintridge, 34.21055uN, 118.20044uW), and 45 adult H. ligniperda were collected from P. halepensis and P. pinea at Bonelli Regional Park (San Dimas, 34.08856uN, 117.81253uW).…”
