Simultaneously, the trees enveloping and situated within the cultural heritage sites are being managed through pruning and removal, thereby mitigating the potential hazards and adverse effects they pose. The new management system for these cultural heritages depends upon scientific outcomes to achieve long-term successful protection. A detailed analysis of these issues is vital for the creation of innovative programs and policies to be implemented not only in Cambodia, but also in other regions.
In the Phyllosticta genus, belonging to the Phyllostictaceae and Botryosphaeriales orders, plant pathogens, endophytes, and saprobes thrive across various global hosts. The current study observed isolates causing leaf spots, taken from Quercusaliena and Viburnumodoratissimum. These isolates were characterized using morphological features and phylogenetic analyses based on data from five genetic loci: ITS, LSU, tef1, act, and gapdh. Confirmation was given to the addition of two new species, Phyllosticta anhuiensis and P. guangdongensis, based on the results. Phylogenetic studies utilizing DNA sequence data show P.anhuiensis and P.guangdongensis to represent two separate lineages within the P.concentrica and P.capitalensis species complexes, unlike any currently classified species in the genus. Pre-formed-fibril (PFF) The morphological characteristics of Phyllosticta anhuiensis and Phyllosticta guangdongensis align with the typical structure of the Phyllosticta genus, but they diverge from their related species due to variations in the length of the conidial appendage.
Two recently discovered Astrothelium species originate from the Yungas forest region of the Bolivian Andes. The defining traits of Astrotheliumchulumanense include pseudostromata matching the thallus' color, largely immersed perithecia with elevated upper portions above the thallus, coated in orange pigment save for the tops of the perithecia; ostioles are fused and apical; the absence of lichexanthone is notable, although the thallus glows orange-yellow under ultraviolet light; a distinct clear hamathecium, 8-spored asci, and amyloid, sizable, muriform ascospores segmented by central septa are also observed. Astrotheliumisidiatum, known exclusively in a sterile state, produces isidia forming clusters on areoles, which effortlessly break apart to reveal a medulla structurally similar to soralia. The two-locus phylogeny's assessment of the species demonstrates that both belong to the Astrothelium s.str. category. The initial documentation of isidia production in the Astrothelium genus, specifically within the Trypetheliaceae family, is presented.
Apiospora, a genus exhibiting a wide host range and geographical distribution, includes endophytes, pathogens, and saprobes. Six Apiospora strains from bamboo leaves, including both diseased and healthy specimens, from Hainan and Shandong, China, were classified phylogenetically using a multi-locus approach. This involved analyzing the ITS, LSU, tef1, and tub2 genes, in concert with observations of morphology, host plant affinity, and environmental distribution. infections in IBD Morphological analyses and phylogenetic relationships establish Apiosporadongyingensis and A. hainanensis as new species, along with a new record of A. pseudosinensis in China. The three taxa are portrayed through both illustrations and descriptions, complemented by comparisons to closely related taxa within their genus.
Thelebolales, exhibiting diverse ecological characteristics, are fungi found globally. This study's morphological and phylogenetic investigation introduces two newly recognized taxa within the Thelebolales, a group whose classification remains a point of contention. Phylogenetic analyses demonstrated that the newly identified taxa established distinct lineages with strong support, diverging from other members of Thelebolales. Sexual structures were not produced by the new taxa that are detailed in this text. We delve into the phylogenetic connections of the novel taxa, contrasting their morphological characteristics with those of other species within Thelebolales.
The specimens collected in southwestern China provided the basis for the description of two new species, Termitomycestigrinus and T.yunnanensis. The venose pileus surface of Termitomycesyunnanensis, a mushroom, displays a striking pattern of grey, olive grey, light grey, and greenish grey tones, concentrated at the center, transitioning to light grey near the margin. A cylindrical white stipe complements the pileus. Termitomycestigrinus's pileus, possessing a densely tomentose to tomentose-squamulose texture and alternating greyish white and dark grey zones, displays a defining morphological trait; similarly, its stipe's bulbous base is notable. The identification of two new species is bolstered by phylogenetic analyses of combined nuclear rDNA internal transcribed spacer ITS1-58S-ITS2 rDNA (ITS), the mitochondrial rDNA small subunit (mrSSU), and the nuclear rDNA large subunit (nrLSU). Further analysis of the morphological variability in T. intermedius includes five newly collected specimens from Yunnan Province, China. In the collections, the colour of the stipe surface and the morphology of the cheilocystidia demonstrated a departure from the original description's specifications. The two new species, along with T.intermedius, are fully described, and a taxonomic key for the 14 Termitomyces species recorded in China is also provided.
Within the Mycocaliciales order (Ascomycota), fungal species demonstrate a wide spectrum of substrate ecologies, often exhibiting high levels of specialization. Within the Chaenothecopsis genus, a considerable number of species are exclusively found on the fresh or solidified resins, or other exudates, of vascular plants. Among New Zealand's botanical species, Chaenothecopsisschefflerae, previously recognized for its dependence on plant exudates, thrives on several endemic angiosperms within the Araliaceae family. In this report, three new species are described: Chaenothecopsis matai Rikkinen, Beimforde, Tuovila & A.R. Schmidt, C. nodosa Beimforde, Tuovila, Rikkinen & A.R. Schmidt, and C. novae-zelandiae Rikkinen, Beimforde, Tuovila & A.R. Schmidt. Their growth is entirely dependent on the exudates of endemic New Zealand Podocarpaceae conifers, primarily on Prumnopitystaxifolia. The restricted host range of all three taxa, along with this, supports the conclusion that they are uniquely found in New Zealand. Insect frass, abundant between the ascomata, holds ascospores or reveals a nascent stage of ascomata growth, signifying insect-mediated fungal dispersal. The first demonstration of Chaenothecopsis in any Podocarpaceae species, and the initial detection of this genus in any gymnosperm exudates in New Zealand, is presented by these three newly identified species.
A mycological survey in the Democratic Republic of the Congo yielded a fungal specimen that displayed morphological characteristics similar to the American species Hypoxylonpapillatum. A polyphasic study of Hypoxylon species, incorporating morphological and chemotaxonomic characteristics, was complemented by a multigene phylogenetic analysis (ITS, LSU, tub2, and rpb2). Comparative study of related genera's representatives revealed that this strain exemplifies a novel Hypoxylaceae species. In contrast, the multi-gene phylogenetic analysis suggested that the novel fungus was grouped with *H. papillatum* within a distinct clade compared to the remaining *Hypoxylon* species. The stromatal extracts underwent ultrahigh performance liquid chromatography coupled to diode array detection and ion mobility tandem mass spectrometry (UHPLC-DAD-IM-MS/MS) based studies. The MS/MS spectra of the primary stromatal metabolites in these species illustrated the creation of novel azaphilone pigments, having a structural similarity to the cohaerin-type metabolites, which are restricted to the Hypoxylaceae. The current results strongly suggest the need to introduce the new genus, Parahypoxylon, at this time. P.papillatum aside, the genus is also characterized by the presence of P.ruwenzoriensesp. Nov., the type species, and Durotheca, its sister genus, were grouped together in a fundamental clade of the Hypoxylaceae.
Colletotrichum species exhibit a multifaceted nature, acting as notorious plant pathogens, saprobes, endophytes, human pathogens, and entomopathogens. Unfortunately, there is a paucity of data regarding Colletotrichum's existence as an endophyte within plants and cultivars like Citrusgrandis cv. Remarkably, the tomentosa plant demonstrates striking qualities. During the 2019 study conducted in Huazhou, Guangdong Province (China), 12 endophytic isolates of Colletotrichum were obtained from this particular host. Phylogenetic analysis, leveraging multiple genes (nuclear ribosomal internal transcribed spacer (ITS), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), chitin synthase 1 (CHS-1), histone H3 (HIS3), actin (ACT), beta-tubulin (-TUB), and glutamine synthetase (GS)), in conjunction with morphological examination, identified six Colletotrichum species, including two novel species, Colletotrichum guangdongense and C. tomentœae. see more Initial reports of C. asiaticum, C. plurivorum, C. siamense, and C. tainanense were made regarding the C. grandis cultivar. Tomentosa is found in every corner of the world. This groundbreaking study comprehensively examines endophytic Colletotrichum species in C. grandis cv. for the first time. Tomentosa's presence is marked throughout China.
Endophytic, pathogenic, and saprophytic roles are often played by Diaporthe species, which exhibit a broad spectrum of plant hosts. Diaporthe strains from China, isolated from damaged Smilax glabra leaves and dead Xanthium strumarium stalks, were determined through morphological and molecular phylogenetic studies utilizing a multi-locus approach, including ITS, calmodulin, histone H3, translation elongation factor 1-alpha, and -tubulin gene sequences. The present study's findings led to the identification, description, and illustration of two new species of interest: Diaportherizhaoensis and D.smilacicola.
