These findings expand the known host range and geographic distribution of Parafenestella and suggest that additional endophytic diversity remains to be discovered in alpine forest ecosystems.
Abstract
Abstract During a mycological survey of high-altitude forests in Xizang (Tibet), China, four endophytic fungal strains were isolated from the asymptomatic tissues of Cupressus gigantea and Rosa sericea. Based on morphological characteristics and multi-locus phylogenetic analyses of a five-gene dataset (ITS, LSU, tub2, tef1, and rpb2), these isolates are introduced as Parafenestella cupressicolasp. nov. and P. xizangensissp. nov. (Cucurbitariaceae, Pleosporales). Phylogenetically, P. cupressicola forms a sister lineage to P. ulmi and P. ulmicola but differs in conidiogenous cell and conidia dimensions. Parafenestella xizangensis shares similar conidial morphology with P. salicis, but differs in molecular sequences. These findings expand the known host range and geographic distribution of Parafenestella and suggest that additional endophytic diversity remains to be discovered in alpine forest ecosystems.
A new species, Ossicaulis, O. gansuensis, collected from the Qilian Mountains Natural Protection Station in Gansu Province, China, is described and illustrated. Its taxonomic position is established through morphological observations and phylogenetic analyses of multi-gene sequences (ITS+LSU+tef1-α+rpb2). Morphological...

Abstract Pseudoplagiostoma fungi are globally widespread, encompassing plant-pathogenic, saprophytic, and endophytic fungal species associated with diverse plant hosts. Four Pseudoplagiostoma isolates were recovered from diseased leaves of Artocarpus hainanensis, Cinnamomum sp., Mallotus hookerianus, and Trachelospermu...

During a survey of wood-decaying fungi in the subalpine forests of Southwest China, distinctive corticioid specimens were collected from fallen Abies trunks. Based on a combination of morphological characteristics and multigene phylogenetic analyses of the internal transcribed spacer (ITS) and nuclear large subunit (nL...

Abstract Fungi in the family Chaetomiaceae are ubiquitous, colonizing diverse substrates and frequently occurring as endophytes in various plant species. Despite their prevalence, knowledge of their association with the Orchidaceae remains limited. In this study, we investigated the diversity of endophytic fungi associ...

During investigations of saprobic microfungi associated with the litter of Bauhinia variegata and Litchi chinensis in Guangdong and Guangxi provinces, southern China, four fungal strains were isolated. Based on combined phylogenetic analyses of LSU, SSU, ITS, and tef1-α gene regions, morphological comparisons, and a Pa...
