Species of <i>Xerampelinae</i> are recognized by their fishy or shrimp odor, browning context, and a green reaction to iron sulfate. However, species delimitation has traditionally relied on morphology and analysis of limited molecular data. Prior taxonomic work in <i>Xerampelinae</i> has led to the description of as many as 59 taxa in Europe and 19 in North America. Here we provide the first multilocus phylogeny of European and North American members based on two nrDNA loci and two protein-coding genes. The resulting phylogeny supports the recognition of 17 species-rank <i>Xerampelinae</i> clades; however, higher species richness (~23) is suggested by a more inclusive nuclear rDNA internal transcribed spacer region ITS1-5.8S-ITS2 (ITS barcode) analysis. Phylogenetic and morphological analyses support three new species with restricted geographic distributions: <i>R. lapponica, R. neopascua</i>, and <i>R. olympiana</i>. We confirm that the European species <i>R. subrubens</i> is present in North America and the North American species <i>R. serissima</i> (previously known as <i>R. favrei</i>) is present in Europe.

In this review, we synthesize our current knowledge on the mechanisms and strategies of communication used by endophytic fungi and their plant hosts.

Since 1913, <i>C. luteorostrata</i> has been reported from various plant feeding Hemiptera in the southeastern United States, but comprehensive morphological and phylogenetic studies of U.S. populations are lacking. The recovery of multiple strains of <i>C. luteorostrata</i> from mycosed EHS in North Carolina provided an opportunity to conduct pathogenicity assays and morphological and phylogenetic studies to investigate genus- and species-level boundaries among the Clavicipitaceae. Pathogenicity assays confirmed that <i>C. luteorostrata</i> causes mortality of EHS crawlers, an essential first step in developing this fungus as a biocontrol. Morphological studies revealed that conidia aligned with previous measurements of the <i>Paecilomyces</i>-like asexual state of <i>C. luteorostrata</i>, with conidiophore morphology consistent with historical observations. Additionally, a <i>Hirsutella</i>-like synanamorph was observed in select <i>C. luteorostrata</i> strains.

Despite the strong support for individual <i>Conoideocrella</i> species, none of the analyses supported the monophyly of <i>Conoideocrella</i> with the inclusion of <i>Dussiella</i>. Due to the paucity of <i>RPB1</i> and <i>RPB2</i> sequence data, <i>EF1-α</i> provided superior delimitation of intraspecies groupings for <i>Conoideocrella</i> and should be used in future studies.
