Abstrakt: During a survey of fungi on electricity utility poles in South Africa, a diverse range of fungi were discovered. Paecilomyces was frequently isolated, with five species identified using ITS and β-tubulin ( BenA ) sequences. These were P. brunneolus , P. dactylethromorphus , P. lecythidis , P. paravariotii and a potential new species. The genomes of 30 of these strains were subsequently sequenced and used in a phylogenomic analysis with 45 previously published genomes of the genus. Phylogenetic analyses were also conducted using ITS, BenA , calmodulin ( CaM ), RNA polymerase II second largest subunit ( RPB2 ), RNA polymerase II largest subunit ( RPB1 ), the genes coding for the theta subunit of the TCP-1 chaperonin complex ( Cct8 ), and for a putative ribosome biogenesis protein ( Tsr1 ). Both phylogenomic and phylogenetic analyses supported the 15 Paecilomyces species currently accepted and confirmed the novelty of the new species, which we describe as P. lignorum . The latter is the sister species of P. brunneolus and belongs to a clade also containing P. variotii and P. paravariotii . Morphologically, the new species produces longer ellipsoidal conidia and grows more restricted on malt extract agar at 30 °C compared to its closest relatives.
