A nectrioid fungus forming a pinkish colony with mainly solitary phialides producing ellipsoid, aseptate conidia in mucoid packets was isolated from Dirinaria applanata. Our taxonomic study based on morphology and phylogenetic analysis using ITS rDNA sequences revealed that the isolates represented a member of the genus Cylindromonium. Based on further morphological examination, nucleotide sequence comparison, and phylogenetic analysis based on LSU rDNA, tef1, and rpb2 in addition to the phylogenetic analysis using the ITS rDNA sequences, the fungus from Dirinaria represents a new species, which is described here as Cylindromonium dirinariaesp. nov. Furthermore, inoculation experiments revealed that this species can also produce perithecia when inoculated on the host lichen in laboratory environments.

从 Dirinaria applanata 中分离出了一种蜜腺真菌，其菌落呈粉红色，主要是单生分生孢子，产生椭圆形、无菌的分生孢子，呈粘液状。我们根据形态学和使用 ITS rDNA 序列进行的系统发育分析进行了分类研究，结果表明分离物代表了圆柱孢属的一个成员。根据进一步的形态学检查、核苷酸序列比较，以及基于 LSU rDNA、tef1 和 rpb2 的系统发育分析和基于 ITS rDNA 序列的系统发育分析，来自 Dirinaria 的真菌代表了一个新种，在此描述为 Cylindromonium dirinariae sp.此外，接种实验表明，在实验室环境中，接种到寄主地衣上，该物种也能产生栖息孢子。引用：Ohmaki A, Okane I：Ohmaki A, Okane I, Crous PW, Verkley GJM (2023).(Ascomycota, Hypocreales), a new nectrioid lichenicolous species on Dirinaria applanata in Japan.Fungal Systematics and Evolution 11: 1-10. doi: 10.3114/fuse.2023.11.01.

The genus Ducellieria ( Ducellieriaceae ) contains three species ( D. chodatii , D. tricuspidata , D. corcontica ), and a single variety ( D. chodatii var. armata ) of obligate endobiotic pollen parasites. These organisms have been first assigned to the green alga genus Coelastrum , as they form very similar spherical structures, but the observation of heterokont zoospores has led to their reclassification to the phylum Oomycota . However, despite their widespread nature, these organisms are only known from their descriptive morphology, and life cycle traits of some species still remain incompletely known. Only the type species, D. chodatii , has been rediscovered several times, but the phylogeny of the genus remains unresolved, since none of its species has been studied for their molecular phylogeny. At present the genus is still included in some algal databases. To clarify the evolutionary affiliation of Ducellieria , efforts were undertaken to isolate D. chodatii from pollen grains, to infer its phylogenetic placement based on nrSSU sequences. By targeted isolation, the pollen endoparasitoid was rediscovered from three lakes in Germany (Mummelsee, Okertalsperre, Knappensee). Apart from the typical coelastrum-like spheroids, oomycetes sporulating directly from pollen grains in a lagenidium-like fashion were observed, and molecular sequences of both types of oomycetes were obtained. Phylogenetic reconstruction revealed that coelastrum-like and lagenidium-like forms are unrelated, with the former embedded within the deep branching early-diverging lineages, and the later stage forming a distinct clade in Peronosporales . Consequently, the life cycle of D. chodatii needs careful revision using single-spore isolates of the species, to infer if previous lifecycle reconstructions that involve various different thallus types are stages of a single species or potentially of several ones.
Ducellieria属(Ducellieriaceae)包含三种(D. chodatii, D. tricuspidata, D. corcontica)和一种专性内源花粉寄生虫(D. chodatii var. armata)。由于它们形成非常相似的球形结构，这些生物最初被分配到绿藻属腔藻，但对异源游动孢子的观察导致它们被重新分类到卵菌门。然而，尽管这些生物分布广泛，但人们只从它们的描述形态中了解它们，一些物种的生命周期特征仍然不完全清楚。只有模式种D. chodatii被重新发现了几次，但该属的系统发育仍然没有得到解决，因为它的物种都没有被研究过它们的分子系统发育。目前，该属仍包括在一些藻类数据库中。为了明确Ducellieria的进化关系，研究人员从花粉粒中分离出chodatii，并根据nrSSU序列推断其系统发育位置。通过定向分离，在德国的三个湖泊(Mummelsee, Okertalsperre, Knappensee)中重新发现了花粉内生寄生虫。除了典型的腔乳状球体外，还观察到直接从花粉粒中以类似于lagenidia的方式产孢的卵菌，并获得了这两种类型卵菌的分子序列。系统发育重建显示，腔乳状体和lagenidim状体是不相关的，前者嵌入在深分支的早期分支谱系中，而后者在Peronosporales中形成一个独特的分支。因此，需要使用该物种的单孢子分离物仔细修改D. chodatii的生命周期，以推断先前涉及各种不同菌体类型的生命周期重建是单一物种的阶段还是可能是多个物种的阶段。

Despite being a small island, Sri Lanka is rich in fungal diversity. Most of the fungi from Sri Lanka have been identified as pathogens of vegetables, fruits, and plantation crops to date. The pleosporalean genus Curvularia ( Dothideomycetes ) includes phytopathogenic, saprobic, endophytic, and human/animal opportunistic pathogenic fungal species. The majority of the plant-associated Curvularia species are known from poaceous hosts. During the current study, 22 geographical locations of the country were explored and collections were made from 10 different poaceous hosts. Morphology and molecular phylogeny based on three loci, including nuclear internal transcribed spacers 1 and 2 with 5.8S nrDNA (ITS), glyceraldehyde-3-phosphate dehydrogenase ( gapdh ), and translation elongation factor 1-α ( tef1 ) supported the description of two new species of fungi described herein as C. aurantia sp. nov. and C. vidyodayana sp. nov. Moreover, novel host-fungal association records for C. chiangmaiensis , C. falsilunata , C. lonarensis , C. plantarum , and C. pseudobrachyspora are updated herein. In addition, five species within the genus Curvularia , viz ., C. asiatica , C. geniculata , C. lunata , C. muehlenbeckiae , and C. verruculosa represent new records of fungi from Sri Lanka.

Downy mildew is one of the most important diseases of commercial sunflower and other Asteraceae hosts, including ornamental Rudbeckia . Plasmopara halstedii has historically been identified as the causal agent of this disease, considered a complex of species affecting nearly 35 genera in various tribes. However, with the use of molecular DNA characters for phylogenetic studies, distinct lineages of P. halstedii in the Asteraceae have been identified, confirmed as distinct or segregated as new species. During August of 2022, a downy mildew was observed on potted Echinacea purpurea grown in a retail greenhouse in Jefferson County, Wisconsin, USA. Phylogenetic analyses of the cytochrome c oxidase subunit 2 ( cox2 ) and nuclear large subunit ribosomal RNA (nc LSU rDNA) gene regions indicated these Plasmopara sp. isolates are not conspecific with P. halstedii . Based on phylogenetic evidence and new host association, the Plasmopara isolates from E. purpurea are here described as Plasmopara echinaceae . Diagnostic morphological characters for this new species were not observed when compared with other isolates of P. halstedii or other Plasmopara species found on Asteraceae hosts, and therefore a list of species-specific substitutions in the cox2 region are provided as diagnostic characters. As this study corresponds to the first observation of downy mildew in cone flowers, it is recommended to follow the required disease prevention guidelines to prevent outbreaks and the establishment of this plant pathogen in production sites.

Wood-inhabiting fungi (WIF), such as polypores, are extremely species-rich and play vital roles in the functioning of forest ecosystems as decomposers. Despite the importance of polypores, our knowledge of the diversity and distribution of these fungi is still poor in general and especially for West Africa. To advance our knowledge we here summarise results from field collections between 2017 and 2021 and present (i) a taxonomic overview, (ii) phylogenetic placements and (iii) an illustrated catalogue of wood-inhabiting polypore fungi with colour pictures. During the field sampling campaigns, we collected 647 specimens. Based on morphological characteristics and molecular barcode data, 76 polypore species belonging to six orders, 15 families and 39 genera were identified. Of the 76 species, 30 are new to the West Africa, 69 new to Benin, and two new combinations Fuscoporia beninensis and Megasporia minuta are proposed. With this summary, we provide new data for further research. Citation: Olou BA, Langer E, Ryvarden L, Krah F-S, Hounwanou GB, Piepenbring M, Yorou NS (2023).
