TL;DR: The evolution of a clade within Fusarium associated with ambrosia beetles in the genus Euwallacea is document, consistent with a strong evolutionary trend toward obligate symbiosis coupled with secondary contact and interspecific hybridization.

TL;DR: The present study highlights the importance of understanding the potential for and frequency of host-switching between Euwallacea and members of the AFC, and that these shifts may bring together more aggressive and virulent combinations of these invasive mutualists.

TL;DR: Results indicate PSHB is associated with a dynamic assemblage of mycangial fungal associates that pose additional risk to native and nonnative hosts in California.

TL;DR: The practical and scientific argument in support of a Fusarium that includes the FSSC and several other basal lineages is reasserted, consistent with the longstanding use of this name among plant pathologists, medical mycologists, quarantine officials, regulatory agencies, students and researchers with a stake in its taxonomy.

TL;DR: The Ambrosiodmus-Flavodon symbiosis is unique in several aspects: it is the first reported association between an ambrosia beetle and a basidiomycotan fungus; the mycosymbiont grows as hyphae in the mycangia, not as budding pseudo-mycelium; and the myCosymbia is a white-rot saprophyte rather than an early colonizer: a previously undocumented wood borer niche.
