Ophiostomatoid fungi isolated from Japanese red pine and their relationships with bark beetles

Predicting sapstain and degrade in fallen trees following storm damage in a Pinus radiata forest

“…Such insects can carry fungal spores on their surface or in specialised structures such as mycangia which evolved in bark beetles as a means of transporting spores of mutualistic fungi (Bleiker et al, 2009;Grebennikov and Leschen, 2010;Masuya et al, 2009;Reay et al, 2005Reay et al, , 2006b. However, in this study, although the incidence of beetle colonisation increased with time, no difference was found in the proportion of sapstain present in discs as a function of beetle colonisation until the last sample time, 67 weeks after the storms in rooted trees.…”

Taxonomy and phylogeny of the Leptographium procerum complex, including Leptographium sinense sp. nov. and Leptographium longiconidiophorum sp. nov.

“…Of these, L. longiconidiophorum was from P. densiflora in Japan adding to several species in Leptographium s. l. reported in association with various bark beetles from P. densiflora in Japan, including L. procerum (Masuya et al 1999(Masuya et al , 2009). All these identifications have been based on morphology, and although L. longiconidiophorum has longer conidiophores than L. procerum, it is possible that some of the isolates reported from Japan as the latter species, might have represented L. longiconidiophorum.…”

Sydowia polyspora Dominates Fungal Communities Carried by Two Tomicus Species in Pine Plantations Threatened by Fusarium circinatum

“…This species seems to be more strongly associated with Tomicus minor Hartig than T. piniperda [62,80], which could explain the low frequency observed. However, this fungus has been also isolated from T. piniperda [61,81], being quite frequent among blue stain fungi carried by this insect species [59]. Penicillium spp.…”
