Palm trees (Arecaceae) are among the most popular ornamental plants worldwide. Despite extensive research on fungi associated with Arecaceae, diversity and ecological dynamics of affecting palms remain poorly studied, although they have significant impact palm health economic value. Furthermore, while fungal has traditionally focused tropical assemblages, in temperate climates offer a unique opportunity to explore non-native habitats. The present study conducted preliminary assessment ecology potential phytopathogenic foliar lesions various host species Portugal, combining morphological examination, PCR-based genomic fingerprinting, biodiversity data analysis. examination 134 sampled from 100 resulted collection 2064 leaf spotting (PLSF), representing diverse assemblage 320 molecular operational taxonomic units (MOTUs) across 97 genera. overall community composition revealed distinct dominated by Neosetophoma, Alternaria, Phoma, Cladosporium, profusion infrequent rare taxa consistent logseries distribution. Significantly positive co-occurrence (CO) patterns prevalent uncommon suggest synergistic interactions enhancing colonisation, persistence, pathogenicity. structures PLSF contrasted markedly fungi, especially prevalence pleosporalean coelomycetes Didymellaceae Phaeosphaeriaceae, including recently introduced or not previously documented genera Arecaceae. This novel suggests that climatic constraints shape structure communities, resulting distinctive assemblages. In addition, assemblages varied significantly species, temperate-native hosting more diverse, coelomycete-enriched communities. findings highlight as hyperdiverse microhabitats harbouring communities intricate complex interplay climatic, host, factors. With climate change altering environmental conditions, identification thriving inhabiting these becomes crucial for predicting shifts pathogen mitigating future disease outbreaks. Understanding is essential identifying threats developing effective management strategies sustainability plants.

Diatrypaceae is a diverse family with worldwide distribution, occurring on wide range of hosts in terrestrial and marine environments, some which are important plant pathogens. During survey ascomycete diversity Guizhou Province, China, three new taxa within Peroneutypa proposed based morphological comparisons phylogenetic analyses combined ITS tub2 sequences data. The newly species Peroneutypaguizhouensis, P.wanfenglinensis P.zhujiashanesis. In addition, Eutypacamelliae was recorded for the first time from an updated description.

Morphology and phylogeny reveal two new species and host records of hyphomycetous fungi on Areca species from marine habitats in Thailand

MycoKeys, Journal Year: 2025, Volume and Issue: 118, P. 179 - 206

Published: June 4, 2025

The marine ecosystem is the largest on Earth, supporting a wide variety of organisms. Fungi in this environment are diverse and play promising ecological roles. This study investigated fungi submerged, decaying plant materials Areca species trapped between rocks seawater Prachuap Khiri Khan Province, Thailand. Morphological multi-gene phylogenetic analysis (LSU-ITS- tub 2-SSU for Tetraploa , ITS-LSU- 2- rpb 2 Rosellinia LSU-ITS- tef 1-α- Musicillium act Sarocladium ) revealed two new species: maritima characterized by presence hilum elongating appendages, distinguished brown to black conidial-like structure composed interwoven, irregular cells without distinct conidiophores produced sterile conditions, unlike other asexual morphs. Additionally, host records ( theobromae gamsii documented, with detailed descriptions their vivo vitro morphologies. Detailed morphological illustrations provided. contributes understanding fungal diversity environments.
