“…In particular, its perithecial characteristics fitted well with descriptions of O. europhioides (Wright and Cain, 1961;Davidson et al, 1967 Relative virulence of the ophiostomatoid fungi Necrotic lesions were formed around all the inoculation points on the inner bark when ophiostomatoid fungi were inoculated (Table 1, Fig. 26).…”

Six ophiostomatoid fungi, i.e., Ceratocystiopsis minuta, Ceratocystis laricicola, Ophiostoma brunneo-ciliatum, O. laricis, O. piceae and Ophiostoma sp., were isolated from the galleries of Ips cembrae on Japanese larch (Larix kaempfer/) logs in central Honshu, Japan. Japanese larch trees approximately 30 yr old were inoculated with all six fungi. Ceratocystis laricicola produced the largest lesions on the inner bark around the inoculation point and the largest dry zone in the sapwood. Furthermore, C. laricicola was the only fungus associated with I. cembrae that had the ability to kill Japanese larch, death occurring in 30-yr-old trees within 3.5 mo after inoculation.

“…A similar species, Grosmannia sp. L1, was reported in a previous paper (Yamaoka et al 1998 (Wright and Cain 1961;Davidson et al 1967). Both fungi have ascospores surrounded by hyaline walls, and appear cucullate in side view, quadrangular in face view, and triangular in end view.…”

Constant association of ophiostomatoid fungi with the bark beetle Ips subelongatus invading Japanese larch logs

Ceratocystiopsis, Ceratocystis, Grosmannia, and Ophiostoma species were isolated from Ips subelongatus and beetle-infested Japanese larch logs collected at several areas in central and northern Honshu Island, Japan, to determine constant associates of I. subelongatus. Ceratocystiopsis minuta, two species of Ceratocystis, three species of Grosmannia, and four species of Ophiostoma were isolated. Of the fungi isolated in the present study, G. laricis, O. brunneociliatum, and O. piceae were constant associates of the beetles. Ceratocystis fujiensis, Ceratocystiopsis minuta, and Ophiostoma sp. F were occasionally isolated with high frequencies of occurrence but were not consistent associates. Ceratocystis fujiensis was most often isolated as the leading fungal invasion in the sapwood of Japanese larch logs invaded by I. subelongatus, confirming that the fungus acts as a primary invader of sapwood in beetle-attacked logs

“…However, it may have occurred among the unidentified Leptographium species reported by Lewinsohn et al (1994), since this fungus has a Leptographium anamorph. Ophiostoma europhioides has a wide geographic distribution and has been isolated from several bark beetles and conifers in Europe and North America (Wright and Cain 1961;Davidson and Robinson-Jeffrey 1965;Davidson et al 1967;Griffin 1968;Olchowecki and Reid 1974;Harding 1989;Krokene and Solheim 1996).…”

Blue-stain fungi were isolated from the Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins, and from Douglas-fir, Pseudotsuga menziesii (Mirb.) Franco, colonized by the beetle. Growth of the three most commonly isolated blue-stain fungi (Leptographium abietinum (Peck) Wingfield, Ophiostoma europhioides (Wright & Cain) Solheim, Ophiostoma pseudotsugae (Rumbold) von Arx), and Ceratocystis rufipenni Wingfield, Harrington, & Solheim, an important associate of the spruce beetle, Dendroctonus rufipennis (Kirby), was studied in sapwood and phloem of live Douglas-fir trees, on malt agar, and on malt agar under oxygen-deficient conditions. The two Ophiostoma species grew better in the phloem and induced longer phloem necroses than the other fungi. Ceratocystis rufipenni and O. europhioides grew better in the sapwood and induced deeper sapwood occlusion. All fungi were relatively fast growing on malt agar, with O. pseudotsugae growing fastest and L. abietinum, slowest. Growth of C. rufipenni and O. europhioides was inhibited less by low oxygen levels than the other fungi, and this may explain why these two fungi were better able to colonize live sapwood. Résumé: Les auteurs ont isolé des champignons du bleuissement à partir de l'insecte, Dendroctonus pseudotsugae Hopkins, vivant sur le douglas taxifolié, et du douglas taxifolié, Pseudotsuga menziesii (Mirb.) Franco, colonisé par ces insectes. Ils ont étudié sur de l'aubier et sur du phloème vivants de douglas taxifolié, sur malt gélosé et sur malt gélosé sous des conditions d'oxygénation déficientes, la croissance des trois champignons du bleuissement les plus fréquemment isolés (Leptographium abietinum (Peck) Wingfield, Ophiostoma europhioides (Wright & Cain) Solheim, Ophiostoma pseudotsugae (Rumbold) von Arx) et du Ceratocystis rufipenni Wingfield, Harrington, & Solheim, un important associé de l'insecte de l'épinette, Dendroctonus rufipennis (Kirby). Les deux espèces d'Ophiostoma croissent mieux dans le phloème et y induisent des nécroses plus longues que les autres champignons. Le C. rufipenni et l'O. europhioides croissent mieux dans le bois d'aubier et y induisent des occlusions plus profondes. Tous les champignons ont une croissance relativement rapide sur malt gélosé, l'O. pseudotsugae poussant le plus vite et le L. abietinum le plus lentement. La croissance du C. rufipenni et de l'O. europhioides est moins inhibée par les faibles teneurs en oxygène que les autres champignons ce qui pourrait expliquer pourquoi ils sont plus aptes à coloniser l'aubier.
