Ophiostomatoid fungi isolated from fallen shoots of Scots pine pruned by Tomicus species in Poland

open access: yesActa Mycologica, 2013
Ophiostomatoid fungi are known to be associated with Tomicus spp. on Pinus sylvestris. However, very little is actually known about the fungi present in the pine shoots damaged by these insects. The aim of this study was to survey species of Ophiostoma s.

Fungal Diversity in Multiple Post-harvest Aged Red Pine Stumps and Their Potential Influence on Heterobasidion Root Rot in Managed Stands Across Minnesota

open access: yesFrontiers in Fungal Biology, 2021
Thinning operations that occur in managed red pine (Pinus resinosa) stands, create tree stumps that can serve as a habitat for fungi, especially Heterobasidion irregulare, the cause of a serious root disease. Different fungi can colonize stumps early and

Oak Wilt Disease May Reduce the Initial Decay Rate of Dead Quercus serrata Stems by Altering Fungal Communities in the Wood

open access: yesEnvironmental Microbiology, Volume 27, Issue 1, January 2025.
To evaluate the effects of oak wilt on wood decomposition, the fungal community and wood decay were monitored for 1.5 years across three forests in Japan. Oak wilt significantly altered the fungal community in the wood and may negatively impact decomposition, particularly during the early stages.

Leptographium pyrinum Is a Mycangial Fungus of Dendroctonus adjunctus

open access: yesMycologia, 1996
Several species of Dendroctonus (Coleop- tera: Scolytidae) have cuticular invaginations, or my- cangia, in the integument which are specialized for carrying specific symbiotic fungi. The mycangium of Dendroctonus adjunctus, located under a callus that surrounds the prothorax, has been recognized but the mycangial fungus has not yet been identified ...
