Polyporus is a taxonomically controversial genus which includes species belonging to six infrageneric groups. Recently, many species of Polyporus have been transferred into other related genera viz. Cerioporus, Favolus, Lentinus, Neofavolus and Picipes based on the phylogenetic and morphological analyses. To ascertain the relationships of Polyporus and its allied genera, eight DNA fragments viz. the internal transcribed spacers 1 and 2 with the 5.8S rDNA (ITS), the nuclear ribosomal large subunit (nLSU), partial translation elongation factor 1-α gene (EF1-α), the mitochondrial small-subunit (mtSSU), the β-tubulin gene (TUB), the gene for RNA polymerase II largest subunit (RPB1), the gene for RNA polymerase II second largest subunit (RPB2) and the nuclear ribosomal small subunit (nSSU), are used in the molecular systematic studies. Phylogenetic analyses were carried out based on two combined datasets (ITS+nLSU) and (ITS+nLSU+EF1α+mtSSU+RPB1+RPB2+nSSU+TUB), and the results indicated that species of Polyporus and its related genera fell into six well supported clades: the picipes clade, the favolus calde, the neofavolus clade, the lentinus clade, the core polyporus clade and the squamosus clade. Moreover, the conserved regions of six DNA fragments (5.8S, nLSU, EF1-α, RPB1, RPB2 and nSSU) were used to analyze the divergence times and evolutionary relationships of Polyporus and its related genera by using BEAST v1.8. Bayesian evolutionary analysis revealed that the ancestor of Polyporales split at about 141.81 Mya, while the mean stem ages of the six major clades of Polyporus and its allied genera were 49–63 Mya. Based on the combined analyses of morphology, phylogenies and divergence times, species in the picipes clade formed the genus Picipes by the coriaceous (fresh) to hard (dry) basidiomata and strongly branched skeleto-binding hyphae; species nested in the favolus clade and the neofavolus clade were separately treated as two distinct genera Favolus and Neofavolus; the polyporoid species in the lentinus clade with central and light-colored stipe and inflated hyphae were transferred into Lentinus, and the core polyporus clade was treated as Polyporus s. str. The squamosus clade contained species belonging to several different genera viz. Datronia, Datroniella, Echinochaete, Mycobonia, Neodatronia, Polyporus s. lat. and Pseudofavolus, but there are no enough efficient morphological evidence to combine all species in the squamosus Mycosphere 13(1): 1–52 (2022) www.mycosphere.org ISSN 2077 7019

Isolates of Magnaporthiopsis (Magnaporthaceae, Magnaporthales) were obtained from turfgrass species with patch disease symptoms in sports fields and golf courses in eastern Australia. Patch disease was characterised by plants with root rot, vascular discolouration and dark, ectotrophic mycelium on the root surfaces. Four new species, Magnaporthiopsis dharug , M. gadigal , M. gumbaynggirr and M. yugambeh , are described based on phylogenetic analysis of concatenated partial DNA sequences of the internal transcribed spacer (ITS) region, RNA polymerase II largest subunit ( RPB1 ) and translation elongation factor 1-alpha ( TEF1α ). The descriptions of the fungi include morphological characteristics and host associations. Magnaporthiopsis dharug was isolated from diseased roots of Cynodon dactylon (couch grass, Bermudagrass), Festuca rubra ssp. commutata (Chewing’s fescue) and Poa annua (winter grass); M. gadigal from diseased roots of Pennisetum clandestinum (kikuyu grass); M. gumbaynggirr from diseased roots of C. dactylon ; and M. yugambeh from diseased roots of P. annua . µm wide, forming mycelial strands and curling back at the Conidiophores hyaline, single or branched.

Plant pathogenic fungi and fungus-like taxa (oomycetes) form part of the ecological makeup of healthy natural forest ecosystems. Some help to eliminate unhealthy trees, while others are essential for the conservation of plant species diversity, particularly soil-borne pathogens. However, many fungal pathogens also have devastating effects on forest ecosystems. Disease impacts are more profound when pathogens newly emerge and these can even wipe out an entire tree population. These organisms have developed a plethora of strategies to colonize and infect plants and there are several factors causing pathogens to emerge. Therefore, to prevent emerging diseases, a thorough understanding of the factors causing them is necessary. It is also important to have a comprehensive understanding of the mechanisms of disease development and propagation to design effective control measures. In this review, we describe the phenomenon of emerging and reemerging pathogens by exemplifying ten important recently emerged forest pathogenic fungi and fungus-like taxa, namely, Ophiostoma novo-ulmi, Ceratocystis fimbriata, Fusarium circinatum, Hymenoscyphus fraxineus, Phyllosticta citricarpa, Neonectria faginata, Sphaerulina musiva, Phytophthora pluvialis, P. agathidicida, and Melampsora × columbiana. They have been listed in order of the most cited to the least cited species based on data obtained from the Web of Science. We provide a review for each species to document its emergence and its negative impact on the host(s). We also revise their taxonomic placement, host and country details, and provide updated phylogenetic trees for each genus. The number of accepted species based on molecular data is also
植物病原真菌和类真菌分类群(卵菌)构成健康天然林生态系统的生态组成的一部分。有些有助于消除不健康的树木，而另一些则对保护植物物种多样性，特别是土壤传播的病原体至关重要。然而，许多真菌病原体也对森林生态系统产生破坏性影响。当病原体新出现时，疾病的影响更为深远，甚至可以消灭整个树木种群。这些生物已经发展出大量的策略来定植和感染植物，并且有几个因素导致病原体出现。因此，为了预防新出现的疾病，有必要彻底了解导致这些疾病的因素。全面了解疾病发生和传播的机制对设计有效的控制措施也很重要。本文以最近出现的10个重要的森林病原真菌和真菌样分类群为例，介绍了新发病原体和再发病原体的现象，即新发病原菌、毛鼻角孢菌、圆形镰刀菌、蜡膜菌、黄根瘤菌、faginata新菌、Sphaerulina musiva、雨疫霉、agathidicida和Melampsora x columbiana。根据从Web of Science获得的数据，它们按照被引用次数最多的物种到被引用次数最少的物种排列。我们对每个物种进行了回顾，以记录其出现及其对宿主的负面影响。我们还修改了它们的分类位置、寄主和国家细节，并为每个属提供了更新的系统发育树。基于分子数据的可接受物种的数量也是

Megasporoporia sensu lato is a common polypore genus in tropics, the members of which are readily recognized in the field because of their resupinate, light-coloured basidiocarps with big pores. The species of the genus usually grow on fresh fallen trunks and branches. The genus was recognized as polyphyletic by molecular analyses and divided into three genera: Megasporia, Megasporoporia sensu stricto and Megasporoporiella. In the present study, phylogenies based on the combined 2-gene (ITS + nLSU) and 4-gene (ITS + nLSU + mtSSU + TEF) sequences datasets of Megasporoporia sensu lato are analysed, and 21 lineages nested in three clades (the Megasporia clade, the Megasporoporia sensu stricto clade and the Megasporoporiella clade) are formed. Based on morphological examination, four new species, Megasporia bambusae, Megasporia fusiformis, Megasporoporia inflata and Megasporoporiella australiae, are described based on materials from Australia, China and Malaysia, and a new combination, Megasporoporiella hubeiensis comb. nov., is proposed. Megasporoporiella pseudocavernulosa is selected as the type species of Megasporoporiella because the previous type species Megasporoporiella cavernulosa was misidentified. Polyporus megasporoporus is the revised name for Megasporoporiella lacerata. In addition, a comparison of main characteristics and an identification key of Megasporoporia sensu lato are provided.

Leaf litter decomposition plays a vital role in the nutrient budget of forest ecosystems. Fungal communities colonising leaf litter are “key players” in decomposition and nutrient recycling, because of their ability to produce a wide range of extracellular enzymes that facilitate breakdown of leaf litter. Fungal colonization of decomposing leaf litter is a sequential process during which fungal communities tend to change both quantitatively and qualitatively. Most previous studies on fungal succession have taken synecological approaches, recording fungal species assemblages at different stages of decomposition in various plant species. This paper brings together various studies on leaf litter decomposition, fungal succession of leaf litter including study methods, succession stages, controlling factors, limitations and future perspectives. We discuss high throughput methods as emerging complementary approaches to better understand species diversity and community dynamics. We propose the importance of current approaches combining morphological and molecular data in fungal succession studies. Nevertheless, there are still opportunities for further breakthroughs in this area as few research groups have applied these techniques to fungal succession experiments.
