“…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.

“…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; 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.

Lily (Lilium spp.) is a valuable ornamental bulb flower plant in Liliaceae, and its bulbs have high edible and medicinal value. Compared with bulb propagation of other lilies, seed propagation and short growth period are the most significant characteristics of Lilium×formolongi. In 2023, leaf rot disease (LRD) was observed on approximately 70% of the Lilium×formolongi seedlings sown in an experimental greenhouse in Wuhan, Hubei province, China. Irregular brown water-soaked spots were discovered in the early stages of infected seedlings. Then, spots spread throughout the leaves and caused the leaves to brown, soften, and wilted. A pathogen associated with symptoms was isolated by incubating sterilized leaves on potato dextrose agar plates at 25 ℃ for 2-3 days. Then, a pure single colony was isolated through a single hyphal tip isolation method. The fungal colony was white with abundant aerial mycelium and produced a yellow pigment diffusible into the agar. Microscopically, isolated mycelia were reticulate and pale yellow, while conidia were dark brown, smooth, and spherical, 7.31 to 6.98 × 4.03 to 3.87μm (average 5.44×5.41μm; n=30); oval in lateral view, and had a light stripe in the middle. To identify the species of the fungus at the molecular level, ITS and EF-1α genes were amplified and sequenced using primers ITS1/ITS4 (M Gardes et al. 1993) and 758F/986R (Carbone and Kohn 1999). The BLAST results in GenBank showed that the ITS(OR523578) and EF-1α(PP066842) sequences of LRD shared 99.82% and 99.24% identity with the distinct Apiospora paraphaeosperma strains (GenBank accession MT040110, ON806628.1, respectively). Combined with the morphology of the colony and conidium, the fungus was identified as Ap. paraphaeosperma. In the pathogenicity test, six healthy leaves were inoculated with mycelium disc and then kept in an incubator (22 ℃, 90% humidity, 16h light /8h darkness). The inoculated leaves showed necrosis and wilt symptoms similar to those observed in the greenhouse, while the control leaves were asymptomatic. A re-isolation, morphology identification and DNA sequencing of the fungus confirmed its infection with Ap. paraphaeosperma in Lilium spp. At present, rot caused by Ap. paraphaeosperma has only been reported in Thailand and South Korea, both of which are found on bamboo stems (Hyde et al. 2016; Sun Lul Kwon et al. 2022). As far as we know, this is the first report of leaf rot of lily caused by Ap. paraphaeosperma in China. This report can help identify this disease and further develop effective control measures.
