Leptographium piriforme sp. nov., from a taxonomically diverse collection of arthropods collected in an aspen-dominated forest in western Canada

Mycologia, 2006
During a survey of fungi associated with arthropods collected in a southern boreal mixedwood forest in Alberta we obtained 29 isolates of a unique species of Leptographium.

Putative origins of the fungus Leptographium procerum

Fungal Biology, 2017
Appropriate management of invasive fungi requires adequate understanding of their global diversities and movement histories. The fungus Leptographium procerum is associated with root-colonizing forest insects in pine forests throughout the world, and may have contributed to the aggressive behaviour of the red turpentine beetle (Dendroctonus valens) in ...

Leptographium sinoprocerum sp. nov., an undescribed species associated with Pinus tabuliformis-Dendroctonus valens in northern China

Mycologia, 2008
During a study of ophiostomatoid fungi associated with the invasive pest Dendroctonus valens in the Pinus tabuliformis ecosystem in northern China, a multigenic (ITS2-LSU, beta-tubulin and EF1-alpha) phylogenetic analysis and examination of morphological

A new Leptographium species from Russia

Mycological Research, 2000
Species of Leptographium are well-known inhabitants of conifers in the Northern Hemisphere, in which they cause a blue-stain. They are also known to be associated with insects, especially bark beetles (Coleoptera: Scolytidae). Surveys of dying stands of Siberian fir (Abies sibirica) have resulted in the consistent isolation of an unknown Leptographium ...

The Anamorph of Ophiostoma Francke-Grosmanniae is a Leptographium

Mycologia, 1992
It has been suggested that the anamorph of Ophiostomafrancke-grosmanniae is a species of Phialocephala with phialidic conidium development. This would make it the only species in OphiostOma with a Phialocephala anamorph. Light and ftuorescence microscopy seemed to confirm the presence ofphialidic conidiogenous cells.

Fungi vectored by the introduced bark beetle Tomicus piniperda in Ontario, Canada, and comments on the taxonomy of Leptographium lundbergii, Leptographium terebrantis, Leptographium truncatum, and Leptographium wingfieldii

Canadian Journal of Botany, 2005
Fungi isolated from Tomicus piniperda (L.) galleries in infected trap logs, standing trees, and directly from insects were identified using morphological features and molecular data obtained from the mitochondrial and nuclear DNA region. Identified strains represented Leptographium wingfieldii Morelet, Leptographium procerum (Kendr.) Wingf ...

Safety evaluation of phosphodiesterase derived from Leptographium procerum

Food and Chemical Toxicology, 2004
5'-Phosphodiesterase is produced by fermentation of the fungus Leptographium procerum and is used to hydrolyse yeast RNA to produce flavour enhancers. To establish the safety in use of this enzyme preparation a number of studies have been performed: analysis for the potential of the production strain to produce toxic secondary metabolites, 28-days oral

THE LEPTOGRAPHIUM COMPLEX. HANTZSCHIA AUERSWALD

Canadian Journal of Botany, 1964
Leptographium phycomyces (Auersw.) Grosm. is transferred to Phialocephala Kendrick because its sporogenous cells are phialides. It is illustrated and re-described from the host and in culture.

Three new species of Leptographium from pine

Mycological Research, 2001
Leptographium species are common inhabitants of fresh conifer logs and lumber that are known for their ability to cause blue-stain and, in some cases, their association with disease. L. procerum has been associated with a root disease although controversy surrounds its role in tree death.
