Phylogenetic relationships and taxonomy of species in ceratocystis sensu lato

TL;DRAbstract

Ceratocystis is a genus of Ascomycete fungi residing in the family Ceratocystidaceae (Order:
\nMicroascales; Class: Sordariomycetes). Species of Ceratocystis are best-known as woundinfecting
\nfungi, which are mostly carried by insects. Little is known regarding the basis of the
\nrelationship between insects and Ceratocystis spp., but in some cases it might extend to levels of
\nmutualism. The taxonomic history of the genus is complex and has, during the course of more
\nthan 100 years, been intertwined with several other genera. However, in recent years, the
\nresolution arising from DNA sequence comparisons has resulted in the recognition of at least four
\nmajor groups within Ceratocystis. major groups within Ceratocystis.
\nCeratocystis species in the broad sense (including Ambrosiella) represent ecologically diverse
\nassemblages, including four very clearly defined groups. One of these groups, which I refer to as
\nthe C. coerulescens sens
