| a new leptographium species associated with the northern spruce engraver, ips perturbatus, in western canada. | an undescribed leptographium species was isolated from the spruce-infesting bark beetle ips perturbatus collected from felled spruce trees and logs in northern british columbia and yukon territory. morphologically, this fungus is similar to l. abietinum and l. hughesii but differed in a number of characteristics (e.g. the arrangement of its conidiophores). the fungus grew optimally at 25 c on 2% malt-extract agar and showed a high level of tolerance to cycloheximide. comparison of rdna and beta- ... | 2006 | 16800314 |
| ophiostomatoid fungi associated with the northern spruce engraver, ips perturbatus, in western canada. | a number of ophiostomatoid fungi were isolated from the spruce-infesting bark beetle, ips perturbatus and its galleries collected from felled spruce trees and logs in northern bc and the yukon territory. isolates were identified to species using morphological characteristics, nuclear ribosomal dna and partial beta-tubulin gene sequences. thirteen morphological and phylogenetic species were identified among the isolates. leptographium fruticetum, leptographium abietinum, ophiostoma bicolor, ophio ... | 2007 | 17066342 |
