“…These isolates are closely related to an isolate from a native lichen in North Carolina (isolate NC1642), which we also characterize here. We compare 9055 and 9094 with two closely related species: C. prunicola, which is associated with wood necrosis in stonefruit trees in South Africa (Damm et al 2010; see also Ivanová & Bernadovičová 2012), and C. cephalothecoides, originally isolated from soil in Japan (Kamiya et al 1995; see also Han et al 2017). Finally, we discuss the challenge of identifying new species in the context of fungal ecology surveys, which often rely only on a single locus and can misidentify taxa based on their closest matches in public databases or simple comparisons of barcode sequences.…”

The ecologically diverse genus Coniochaeta (Coniochaetaceae, Ascomycota) contains numerous endophytic strains that occur in healthy leaves and lichen thalli in temperate and boreal North America. These endophytes frequently represent undescribed species. Here we examine two endophytic isolates of Coniochaeta from healthy photosynthetic tissue of Platycladus orientalis (Cupressaceae), a conifer cultivated for horticultural use in Arizona, USA. On the basis of morphology, in vitro assays, phylogenetic analyses of two loci, and analyses of whole genome data, we designate these endophytes as a novel species, Coniochaeta endophytica sp. nov. Strains of C. endophytica are closely related to an isolate from a native lichen in North Carolina, which we also characterize here. We compare C. endophytica with two known species that appear to be close relatives: C. prunicola, associated with wood necrosis in stonefruit trees in South Africa, and C. cephalothecoides, isolated from soil in Asia. The new species is distinct in phylogenetic, in vitro, and whole-genome analyses from C. prunicola, and differs slightly in conidiophore morphology from that species. Although available sequence data for C. cephalothecoides are of uncertain relation to the type specimen for that species, our results support the distinctiveness of C. endophytica on the basis of morphology, perithecial formation, and phylogenetic analyses. We discuss the challenge of identifying new species in the context of fungal ecology surveys, such as those for endophytes, which often rely only on a single locus and can misidentify taxa based on their closest matches in public databases or simple comparisons of barcode sequences alone.

“…The majority of the isolates found in our propolis samples belonged to the genera Coniochaeta, Aspergillus , Penicillium , Cladosporium , and Fusarium . Among the dominant genera in the obtained collection , Coniochaeta is characterized by the ability to grow in an acidic environment [ 47 ] and members of this genus have been previously isolated from young plants [ 48 ], floral nectar [ 49 ], and fruit trees [ 50 ]. In this way, their origin could be attributed to honeybees' gut microbiota as a source of acidophilic microorganisms and/or from plant sources during the foraging season.…”

Discovering new species and interesting bioactive metabolites from customary sources is becoming progressively laborious. Propolis constitutes the largest diversified reserve of microbial constituents in the beehive. However, fungal communities associated with these environments remain insufficiently established. We present the first detailed investigation of the cultivable fungal community associated with Tunisian propolis, and we evaluate its antibacterial properties against pathogenic bacteria. A total of 80 fungal strains were isolated from propolis samples derived from seven different Tunisian locations. The majority of the isolated fungi were classified as Ascomycota (97.5%), and only 2.5% belonged to Basidiomycota. Our collection was clustered into 15 genera, among which Coniochaeta (36.25%), Aspergillus (15%), Penicillium (13.75%), Cladosporium (10%), Fusarium (7.5%), Didymella (5%), and Alternaria (3.75%) were the most common. Evaluation of the antibacterial activity revealed that 25.6% of the total community showed a broad range of antibacterial activity. Particularly, the Penicillium griseofulvum CC8 strain has manifested the strongest inhibitory effects against all the tested bacteria.

“…In that study, two strains isolated as endophytes from healthy, mature foliage of Platycladus orientalis (Cupressaceae) in an arboretum in Arizona, USA were found to be affiliated with, but distinct from, the ex-type and paratype of C. prunicola (CBS 120875 and CBS 121445, respectively;Damm et al 2010). The strains representing C. prunicola occurred in association with necrotic wood of stonefruit trees in South Africa (Prunus armeniaca and P. persica, respectively) (see Damm et al 2010; see also Ivanová & Bernadovičová 2012). Harrington et al ( 2019) concluded that the endophytic strains of interest from Arizona represented a novel species therein described as C. endophytica.…”

Coniochaeta (Coniochaetaceae, Ascomycota) is a diverse genus that includes a striking richness of undescribed species with endophytic lifestyles, especially in temperate and boreal plants and lichens. These endophytes frequently represent undescribed species that can clarify evolutionary relationships and trait evolution within clades of previously classified fungi. Here we extend the geographic, taxonomic, and host sampling presented in a previous analysis of the clade containing Coniochaeta endophytica, a recently described species occurring as an endophyte from North America; and C. prunicola, associated with necroses of stonefruit trees in South Africa. Our multi-locus analysis and examination of metadata for endophyte strains housed in the Robert L. Gilbertson Mycological Herbarium at the University of Arizona (ARIZ) (1) expands the geographic range of C. endophytica across a wider range of the USA than recognized previously; (2) shows that the ex-type of C. prunicola (CBS 120875) forms a well-supported clade with endophytes of native hosts in North Carolina and Michigan, USA; (3) reveals that the ex-paratype for C. prunicola (CBS 121445) forms a distinct clade with endophytes from North Carolina and Russia, is distinct morphologically from the other taxa considered here, and is described herein as Coniochaeta lutea; and (4) describes a new species, Coniochaeta palaoa, here identified as an endophyte of multiple plant lineages in the highlands and piedmont of North Carolina. Separation of CBS 120875 and CBS 121445 into C. prunicola sensu stricto and C. lutea is consistent with previously described genomic differences between these isolates, and morphological and functional differences among the four species (C. endophytica, C. prunicola, C. palaoa, and C. lutea) underscore the phylogenetic relationships described here. The resolving power of particular loci and the emerging perspective on the host- and geographic range of Coniochaeta and the C. endophytica / C. prunicola clade are discussed.
