Many Apiospora species have been isolated from bamboo plants – to date, 34 bambusicolous Apiospora species have been recorded. They are known as saprophytes, endophytes, and plant pathogens. In this study, 242 bambusicolous Apiospora were isolated from various bamboo materials (branches, culms, leaves, roots, and shoots) and examined using DNA sequ...

Tubakiaceae represents a distinct lineage of Diaporthales, including its type genus Tubakia and nine additional known genera. Tubakiaceous species are commonly known as endophytes in leaves and twigs of many tree species, but can also be plant pathogens causing conspicuous leaf symptoms. In the present study, isolates were obtained from diseased le...

... Morphologically, Apiospora and Arthrinium lack clear diagnostic features, although species of Arthrinium often produce conidia of various shapes (Minter and Cannon 2018;Pintos and Alvarado 2021), while most species of Apiospora have rounded lenticular conidia (Li et al. 2023;Liao et al. 2023). Ecologically, most sequenced collections of Arthrinium were found on Cyperaceae or Juncaceae in temperate, cold, or alpine habitats, while those of Apiospora were mainly collected on Poaceae, as well as various other plant host families, in a wide range of habitats, including tropical and subtropical regions (Dai et al. 2016;Jiang et al. 2018;Wang et al. 2018;Feng et al. 2021;Tian et al. 2021;Kwon et al. 2022;Monkai et al. 2022). With the addition of molecular evidence and the expansion of the sample, the latest phylogenetic analysis suggests that Arthrinium s. str. ...
Apiospora species are widely distributed fungi with diverse lifestyles, primarily functioning as plant pathogens, as well as exhibiting saprophytic and endophytic behaviors. This study reports the discovery of three new species of Apiospora, namely A. gongcheniae, A. paragongcheniae, and A. neogongcheniae, isolated from healthy Poaceae plants in China. These novel species were identified through a multi-gene phylogenetic analysis. The phylogenetic analysis of the combined ITS, LSU, tef1, and tub2 sequence data revealed that the three new species formed a robustly supported clade with A. garethjonesii, A. neogarethjonesii, A. setostroma, A. subrosea, A. mytilomorpha, and A. neobambusae. Detailed descriptions of the newly discovered species are provided and compared with closely related species to enhance our understanding of the genus Apiospora.
... A fungus-host distribution of Arthrinium species (most of which have been synonymized under Apiospora) was provided by Wang et al. [11]. The data showed that Poaceae and Cyperaceae are the dominant host plant families, especially the former [10,12,14,17,20,22,42,62,63]. There have been no previous reports of Apiospora species from ferns, likely due to the neglect of fungi on ferns [64,65]. ...
Endophytic fungi isolated from medicinal ferns serve as significant natural resources for drug precursors or bioactive metabolites. During our survey on the diversity of endophytic fungi from Dicranopteris species (a genus of medicinal ferns) in Guizhou, Apoiospora was observed as a dominant fungal group. In this study, seven Apiospora strains, representing four new species, were obtained from the healthy plant tissues of three Dicranopteris species—D. ampla, D. linearis, and D. pedata. The four new species, namely Apiospora aseptata, A. dematiacea, A. dicranopteridis, and A. globosa, were described in detail with color photographs and subjected to phylogenetic analyses using combined LSU, ITS, TEF1-α, and TUB2 sequence data. This study also documented three new hosts for Apiospora species.
