“…Most species of Pseudoplagiostomataceae were isolated from Eucalyptus ( Myrtaceae ) ( Pseudoplagiostoma corymbiae , P. corymbiicola , P. eucalypti , P. oldii , and P. variabile ), especially P. eucalypti with more than 40 strains [ 1 , 4 , 5 , 10 ]. Recently, other hosts were reported, including Anacardiaceae ( P. mangiferae and P. myracrodruonis ), Dipterocarpaceae ( P. dipterocarpi and P. dipterocarpicola ), Fagaceae ( P. castaneae ) [ 2 , 3 , 7 , 8 , 9 ]. This study puts more families in the host list, and they are Cyatheaceae ( P. alsophilae ), Gramineae ( P. bambusae ), and Lauraceae ( P. machili ).…”

“…Pseudoplagiostoma species were mainly reported as endophytes, plant pathogens, or saprobes in various regions, viz. Asia, North America, Oceania, and South America [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ]. As a type species, P. eucalypti was reported with more than 40 strains in the whole world (NCBI Nucleotide database, , accessed on 6 December 2022).…”

Species of Pseudoplagiostomataceae were mainly introduced as endophytes, plant pathogens, or saprobes from various hosts. Based on multi-locus phylogenies from the internal transcribed spacers (ITS), the large subunit of nuclear ribosomal RNA gene (LSU), partial DNA-directed RNA polymerase II subunit two gene (rpb2), the partial translation elongation factor 1-alpha gene (tef1α), and the partial beta-tubulin gene (tub2), in conjunction with morphological characteristics, we describe three new species, viz. Pseudoplagiostoma alsophilae sp. nov., P. bambusae sp. nov., and P. machili sp. nov. Molecular clock analyses on the divergence times of Pseudoplagiostomataceae indicated that the conjoint ancestor of Pseudoplagiostomataceae and Apoharknessiaceae occurred in the Cretaceous period. and had a mean stem age of 104.1 Mya (95% HPD of 86.0–129.0 Mya, 1.0 PP), and most species emerged in the Paleogene and Neogene period. Historical biogeography was reconstructed for Pseudoplagiostomataceae by the RASP software with a S–DEC model, and suggested that Asia, specifically Southeast Asia, was probably the ancestral area.

“…The URM culture collection is the most important fungal collection in Brazil, representing an abundant and diversified strain collection, which contains about 8,000 fungal names and have preserved 98,000 fungal cultures belonging to the most diverse groups. Among these cultures, there are strains deposited by Augusto Chaves Batista and his collaborators during their work in the former Instituto de Micologia da Universidade do Recife (IMUR), highlighting this collection as a reservoir of fungal diversity, which is recently being reviewed based on the modern taxonomic analyses (morphological and molecular), and is also being biotechnologically characterized in relation to the production of enzymes, and other secondary metabolites (Maciel et al 2013;Moreira et al 2014;Sousa et al 2015;Bezerra et al 2017a;b;Cruz et al 2017;Lisboa et al 2017;Barbosa et al 2018;Bezerra et al 2019).…”

Twenty-seven Tritirachium strains were present in the URM culture collection originally founded in Brazil by Augusto Chaves Batista. Fifteen freshly-prepared cultures were obtained from these original strains preserved under mineral oil. DNA was extracted for analysing phylogenetic relationships using the sequence information available from Tritirachium type materials and reference strains. Phylogenetic analysis using the internal transcribed spacer (ITS) ribosomal DNA sequences revealed that eight of these strains belong to the same clade as of T. oryzae and that the four other strains belong to the same clade as of T. candoliense. The strain URM 38, which was previously identified as "T. brumptii", appeared to exist as a single lineage, related to T. roseum and T. candoliense. Based on morphological features and multi-locus phylogenetic analysis, including the analyses of ITS and LSU rDNA, and rpb2 sequences, we propose that URM 38 belongs to the new species T. batistae. This novel species exhibited velutinous to cottony colonies of varying colour, septate hyphae without clamp connections, conidiophores reduced to conidiogenous cells, conidiogenous cells with a distinct sympodial rachis, and single-cell conidia that was globose to subglobose, obovoid, smooth, and hyaline. The morphological features of species accepted in Tritirachium are included in this study.

“…The asexual structures of the genus Pseudoplagiostoma include acervular to pycnidial conidiomata with cylindrical to ampulliform conidiogenous cells and aseptate ellipsoidal conidia; the sexual structures are depressed globose or elliptical ostiolate perithecia with subcylindrical to long obovoid asci, which bear eight, two seriate, hyaline, medianly one-septate ellipsoidal ascospores with tapering ends and terminal elongate appendages (Cheewangkoon et al, 2010). Pseudoplagiostoma species are distinguished using morphological characteristics of the conidia (size, color, and shape) (Suwannarach et al, 2016) and size of conidiomata or conidiogenous cells (Bezerra et al, 2019). Multigene-locus sequence phylogenies have also been used to distinguish different Pseudoplagiostoma species.…”

Leaf spot disease is commonly found on leaves of avocado plants in avocado orchards in Taiwan. Needle-like spots with yellow halos appear on diseased avocado leaves at the incipient stage, and these spots gradually enlarge and become brown lesions with black-brown centers. The causal agent of this disease is unknown. A Pseudoplagiostoma species was collected from these leaf spots. Evaluation of morphological traits and phylogenetic analysis using the ribosomal DNA internal transcribed spacer operon, β-tubulin, and partial large subunit of ribosomal DNA markers identified this fungal species as a novel species, Pseudoplagiostoma perseae sp. nov. A pathogenicity test was conducted on three avocado cultivars, ‘Choquette,’ ‘Hall,’ and ‘Hung Shin Yuan.’ After 2 weeks of inoculation, needle-like leaf spots appeared on all three cultivars, and P. perseae was re-isolated from the spots of all inoculated leaves, fulfilling Koch’s postulates. This is the first report describing the novel species P. perseae, which was validated as the causal agent of avocado leaf spot disease.
