“…Phoma -like asexual morphs have been shown to be scattered within the Pleosporineae, Pleosporales (Chen et al 2017, Valenzuela-Lopez et al 2018). While trying to resolve the natural classification of Phoma -like species in Pleosporales, several new families have been introduced within the sub-order Pleosporineae by various authors (Zhang et al 2009, 2012, Hyde et al 2013, Ariyawansa et al 2015, Hernández-Restrepo et al 2017, Valenzuela-Lopez et al 2018). …”

“…The Pleosporales is considered to be the largest and the most diverse order of the class Dothideomycetes, comprising over 4700 species classified in 53 families (Hyde et al 2013, Ariyawansa et al 2015, Hernández-Restrepo et al 2017, Valenzuela-Lopez et al 2018). Pleosporalean species are characterised by pseudothecial ascomata usually with a papilla and a peridium composed of several layers of cells (Zhang et al 2009, 2012, Hyde et al 2013, Jaklitsch and Voglmayr 2016, Jaklitsch et al 2017).…”

“…Ascospores are generally septate but vary in colour and shape, with or without a gelatinous sheath (Zhang et al 2009, 2012, Hyde et al 2013, Jaklitsch and Voglmayr 2016, Jaklitsch et al 2017). Asexual morphs can be coelomycetous or hyphomycetous (Zhang et al 2009, 2012, Hyde et al 2013, Ariyawansa et al 2014, 2015, Hernández-Restrepo et al 2017, Valenzuela-Lopez et al 2018). Members of Pleosporales are ubiquitous, occurring in various habitats and can be recognised as epiphytes, endophytes or parasites of living leaves or stems, hyperparasites on fungi or insects, lichenised or saprobes of dead plant stems, leaves or bark (Zhang et al 2012, Hyde et al 2013, Ariyawansa et al 2014).…”

“…The suborder Massarineae was proposed by Zhang et al (2009) and currently comprises 12 families (Tanaka et al 2015). Pleosporineae contains numerous economically important plant and human pathogens and, at present, the suborder comprises 20 families (Valenzuela-Lopez et al 2018). …”

Tzeananiaceae, a new pleosporalean family associated with Ophiocordyceps macroacicularis fruiting bodies in Taiwan

The order Pleosporales comprises a miscellaneous group of fungi and is considered to be the largest order of the class Dothideomycetes. The circumscription of Pleosporales has undergone numerous changes in recent years due to the addition of large numbers of families reported from various habitats and with a large amount of morphological variation. Many asexual genera have been reported in Pleosporales and can be either hyphomycetes or coelomycetes. Phoma-like taxa are common and have been shown to be polyphyletic within the order and allied with several sexual genera. During the exploration of biodiversity of pleosporalean fungi in Taiwan, a fungal strain was isolated from mycelium growing on the fruiting body of an Ophiocordyceps species. Fruiting structures that developed on PDA were morphologically similar to Phoma and its relatives in having pycnidial conidiomata with hyaline conidia. The fungus is characterised by holoblastic, cylindrical, aseptate conidiogenous cells and cylindrical, hyaline, aseptate, guttulated, thin-walled conidia. Phylogenetic analysis based on six genes, ITS, LSU, rpb2, SSU, tef1 and tub2, produced a phylogenetic tree with the newly generated sequences grouping in a distinct clade separate from all of the known families. Therefore, a new pleosporalean family Tzeananiaceae is established to accommodate the monotypic genus Tzeanania and the species T.taiwanensis in Pleosporales, Dothideomycetes. The Ophiocordyceps species was identified as O.macroacicularis and this is a new record in Taiwan.

Genomic features of lichen‐associated black fungi

Lichens are mutualistic associations consisting of a primary fungal host, and one to few primary phototrophic symbiont(s), usually a green alga and/or a cyanobacterium. They form complex thallus structures, which provide unique and stable habitats for many other microorganisms. Frequently isolated from lichens are the so‐called black fungi, or black yeasts, which are mainly characterized by melanized cell walls and extremophilic lifestyles. It is presently unclear in which ways these fungi interact with other members of the lichen symbiosis. Genomic resources of lichen‐associated black fungi are needed to better understand the physiological potential of these fungi and shed light on the complexity of the lichen consortium. Here, we present high‐quality genomes of 14 black fungal lineages, isolated from lichens of the rock‐dwelling genus Umbilicaria. Nine of the lineages belong to the Eurotiomycetes (Chaetothyriales), four to the Dothideomycetes, and one to the Arthoniomycetes, representing the first genome of a black fungus in this class. The PacBio‐based assemblies are highly contiguous (5–42 contigs per genome, mean coverage of 79–502, N50 of 1.0–7.3 mega‐base‐pair (Mb), Benchmarking Universal Single‐Copy Orthologs (BUSCO) completeness generally ≥95.4%). Most contigs are flanked by a telomere sequence, suggesting we achieved near chromosome‐level assemblies. Genome sizes range between 26 and 44 Mb. Transcriptome‐based annotations yielded ~11,000–18,000 genes per genome. We analyzed genome content with respect to repetitive elements, biosynthetic genes, and effector genes. Each genome contained a polyketide synthase gene related to the dihydroxynaphthalene‐melanin pathway. This research provides insights into genome content and metabolic potential of these relatively unknown, but frequently encountered lichen associates.
