“…Pará rubber is vulnerable to many pests and diseases, but it is still a mystery why only a few fungal species have been found on rubber (Senwanna et al 2021). Pará rubber tree was introduced to China from Malaysia, presumably by seed and endemic fungi are unlikely to follow; therefore, new fungi colonise Pará rubber through host-shifting or host-jumping (Roy 2001;Senwanna et al 2019Senwanna et al , 2021. Fungi associated with Pará rubber are found in different life modes such as saprobic, endophytic and pathogenic (Gazis and Chaverri 2010;Monkai et al 2017;Senwanna et al 2021).…”

“…In addition, Senwanna et al (2021) reported that three species from their collections had previously been reported from Pará rubber in the Amazon Forest (Spaulding 1961) and most of the taxa reported on Pará rubber have been found in Thailand. Moreover, Senwanna et al (2019) discovered that Muyocopron dipterocarpi may have jumped from its original host. Dipterocarpus tuberculatus, to the Pará rubber host and adapted to the new host in Thailand.…”

The tropical areas in southern and south-western Yunnan are rich in fungal diversity. Additionally, the diversity of seed flora in Yunnan Province is higher than in other regions in China and the abundant endemic species of woody plants provide favourable substrates for fungi. Rubber plantations in Yunnan Province are distributed over a large area, especially in Xishuangbanna. During a survey of rubber-associated fungi in Yunnan Province, China, dead rubber branches with fungal fruiting bodies were collected. Morphological characteristics and multigene phylogenetic analyses (ITS, LSU, SSU, rpb2 and tef1-α) revealed four distinct new species, described herein as Melomastia puerensis, Nigrograna lincangensis, Pseudochaetosphaeronema lincangensis and Pseudochaetosphaeronema xishuangbannaensis. Detailed descriptions, illustrations and phylogenetic trees are provided to show the taxonomic placements of these new species.

Pleurotremataceae species are saprobes on decaying wood in terrestrial, mangrove, and freshwater habitats. The generic boundary of the family has traditionally been based on morphology. All genera of Pleurotremataceae have a high degree of morphological overlap, of which the generic circumscription of Melomastia and Dyfrolomyces has not been well resolved. Thus, the delimitation of genera has always been challenging. Melomastia traditionally differs from Dyfrolomyces in having 2-septate, oblong, with obtuse-ends ascospores. These main characteristics have been used to distinguish Melomastia from Dyfrolomyces for a long time. However, the above characteristics sometimes overlap among Dyfrolomyces and Melomastia species. Based on the morphology and multigene phylogeny with newly obtained data, we synonymized Dyfrolomyces under Melomastia following up-to-date results. Four novel species (i.e., Melomastia fusispora, M. oleae, M. sichuanensis and M. winteri) collected from the dead branches of Olea europaea L. in Chengdu Olive Base, Sichuan Province in China are introduced based on detailed morphological characterization and phylogenetic analyses of sequences based on nuclear ribosomal (LSU and SSU) and protein-coding gene (tef1-α). The 11 new combinations proposed are Melomastia aquatica (= Dyfrolomyces aquaticus), M. chromolaenae (= D. chromolaenae), M. distoseptata (= D. distoseptatus), M. mangrovei (= D. mangrovei), M. marinospora (= D. marinosporus), M. neothailandica (= D. neothailandicus), M. phetchaburiensis (= D. phetchaburiensis), M. sinensis (= D. sinensis), M. thailandica (= D. thailandica), M. thamplaensis (= D. thamplaensis) and M. tiomanensis (= D. tiomanensis).

“…Roy [20] suggested the terms "host shift," which only describes the fungi shifting to closely related host taxa, i.e., host tracking coevolution, and "host jumping" which is used for fungi jumping to unrelated or geographically associated hosts. Senwanna et al [21] reported that Muyocopron dipterocarpi probably jumped from Dipterocarpus tuberculatus to an introduced host (rubber). In this study, we assume that mango-associated saprobes also probably jumped from various hosts in subtropical to tropical regions, mainly by the agricultural activities.…”

Pleosporales is the largest fungal order with a worldwide distribution in terrestrial and aquatic environments. During investigations of saprobic fungi associated with mango (Mangifera indica)) in Baoshan and Honghe, Yunnan, China, fungal taxa belonging to pleosporales were collected. Morphological examinations and phylogenetic analyses of ITS, LSU, SSU, rpb2 and tef1-α loci were used to identify the fungal taxa. A new genus, Mangifericomes; four new species, namely Mangifericomes hongheensis, Neomassaria hongheensis, Paramonodictys hongheensis, and Paramonodictys yunnanensis; and six new host and country records, namely Byssosphaeria siamensis, Crassiparies quadrisporus, Paradictyoarthrinium aquatica, Phaeoseptum mali, Torula fici, and Vaginatispora amygdali, are introduced. Photoplates, full descriptions, and phylogenetic trees to show the placement of new and known taxa are provided.
