“…Neopestalotiopsis drenthii, N. maddoxii, N. olumideae, N. vheenae, and N. zakeelii formed well-supported monophyletic clades in the phylogenetic analysis. The topology of our phylogeny is similar to those generated in earlier studies [29,57].…”

Macadamia (Macadamia integrifolia) is native to eastern Australia and produces an edible nut that is extensively cultivated in commercial orchards in several countries. Little is known about the diversity of fungi associated with diseases of macadamia inflorescences. A survey of fungi associated with the dry flower disease of macadamia detected several isolates of Neopestalotiopsis (Pestalotiopsidaceae, Sordariomycetes). Five new species of Neopestalotiopsis were identified based on molecular phylogenetic analyses of concatenated gene sequences of the internal transcribed spacer (ITS), β-tubulin (TUB), and the translation elongation factor 1-alpha (TEF1α). The new species are named Neopestalotiopsis drenthii, N. maddoxii, N. olumideae, N. vheenae, and N. zakeelii, and are described by molecular, morphological, and cultural characteristics. The ecology of the isolates and their pathogenic, saprophytic, or commensal ability were not determined.

“…have been reported in Australia [5,8], Brazil [26], and China [25]. Many new pestalotioid species have been introduced in recent years [27][28][29][30][31][32][33]. Many unidentified isolates of Neopestalotiopsis were obtained from macadamia racemes with dry flower symptoms.…”

“…The highest diversity of pestalotiopsis-like fungi is recorded in tropical and subtropical countries ( Jiang et al 2022a ; Peng et al 2022 ; Xiong et al 2022 ; Seifollahi et al 2023 ; Sun et al 2023 ). While most pestalotiopsis-like taxa are associated with plants ( Maharachchikumbura et al 2011 ), investigations regarding their biodiversity and occurrence in unusual habitats are rare ( Liu et al 2021 ; Rajulu et al 2022 ).…”

“…Environmental factors including temperature and pH are the most important components mediating fungal growth and helping researchers understand the biology of fungal taxa. In general, pestalotiopsis-like fungi show optimal growth at 20–30 °C ( Liu 1995 ; Tsukamoto and Hino 1956 ; Hopkins and McQuilken 2000 ; Liu et al 2021 ). Most of the known pestalotiopsis-like fungi typically have a wide pH optimum, regularly covering 5–9 pH units without substantial inhibition of their growth ( Wheeler et al 1991 ; Nevarez et al 2009 ; Das et al 2010 ).…”

Pestalotiopsissensu lato, commonly referred to as pestalotiopsis-like fungi, exhibit a broad distribution and are frequently found as endophytes, saprobes and pathogens across various plant hosts. The taxa within pestalotiopsis-like fungi are classified into three genera viz. Pestalotiopsis, Pseudopestalotiopsis and Neopestalotiopsis, based on the conidial colour of their median cells and multi-locus molecular phylogenies. In the course of a biodiversity investigation focusing on pestalotiopsis-like fungi, a total of 12 fungal strains were identified. These strains were found to be associated with stromata of Beauveria, Ophiocordyceps and Tolypocladium in various regions of Taiwan from 2018 to 2021. These strains were evaluated morphologically and multi-locus phylogenetic analyses of the ITS (internal transcribed spacer), tef1-α (translation elongation factor 1-α) and tub2 (beta-tubulin) gene regions were conducted for genotyping. The results revealed seven well-classified taxa and one tentative clade in Pestalotiopsis and Neopestalotiopsis. One novel species, Pestalotiopsis manyueyuanani and four new records, N. camelliae-oleiferae, N. haikouensis, P. chamaeropis and P. hispanica, were reported for the first time in Taiwan. In addition, P. formosana and an unclassified strain of Neopestalotiopsis were identified, based on similarities of phylogeny and morphology. However, the data obtained in the present study suggest that the currently recommended loci for species delimitation of pestalotiopsis-like fungi do not deliver reliable or adequate resolution of tree topologies. The in-vitro mycelial growth rates of selected strains from these taxa had an optimum temperature of 25 °C, but growth ceased at 5 °C and 35 °C, while all the strains grew faster under alkaline than acidic or neutral pH conditions. This study provides the first assessment of pestalotiopsis-like fungi, associated with entomopathogenic taxa.

“…Notes: This species is clearly a member of Neopestalotiopsis according to the results of phylogenetic analyses ( Figure 4 ). Although it was listed as N. coffeae-arabicae in various phylogenies [ 30 , 35 , 41 , 53 , 63 , 68 ], this combination is neither present in the Index of Fungi nor Mycobank, and could also not be traced in the literature, indicating that it has not been validly published, which is therefore performed here.…”

Avocado (Persea americana) represents an important emerging tropical crop in Italy, especially in the southern regions. In this study, young plants of avocado showing symptoms of stem and wood lesion, and dieback, were investigated. Isolations from symptomatic tissues consistently yielded colonies of Neopestalotiopsis-like species. The characterization of representative isolates was based on the observation of morphological characters, the effect of temperature on mycelial growth rate, and on the sequencing of three different gene regions, specifically ITS, TEF1, and TUB2. Phylogenetic analyses were conducted based on maximum parsimony and maximum likelihood approaches. The results showed the presence of two species, viz. Neopestalotiopsis rosae and N. siciliana, the latter of which is here described as a new species. Pathogenicity tests were conducted using the mycelial plug technique on young potted avocado trees for both Neopestalotiopsis species. The results showed that both species were pathogenic to avocado. This study represents the first report of these two species affecting avocado and results in the description of a new species within the genus Neopestalotiopsis. Based on phylogeny, Pestalotiopsis coffeae-arabicae is combined in Neopestalotiopsis.
