Based on a Newly-Discovered Species

MycoKeys 76: 1–16. https://doi.org/10.3897/mycokeys.76.58628 Abstract During the field studies, aTranslucidithyrium -like taxon was collected in Xishuangbanna of Yunnan Province, during an investigation into the diversity of microfungi in the southwest of China. Morpho- logical observations and phylogenetic analysis of combined LSU and ITS sequences revealed that the new taxon is a member of the genus Translucidithyrium and it is distinct from other species. Therefore, Translucidithyrium chinense sp. nov. is introduced here. The Maximum Clade Credibility (MCC) tree from LSU rDNA of Translucidithyrium and related species indicated the divergence time of existing and new species of Translucidithyrium was crown age at 16 (4–33) Mya. Combining the estimated diver- gence time, paleoecology and plate tectonic movements with the corresponding geological time scale, we proposed a hypothesis that the speciation (estimated divergence time) of T. -

Dissertation Advisor: Professor Donald H. Pfister Danny Haelewaters STUDIES OF THE LABOULBENIOMYCETES: DIVERSITY, EVOLUTION, AND PATTERNS OF SPECIATION ABSTRACT CHAPTER 1: Laboulbeniales is one of the most morphologically and ecologically distinct orders of Ascomycota. These microscopic fungi are characterized by an ectoparasitic lifestyle on arthropods, determinate growth, lack of asexual state, high species richness and intractability to culture. DNA extraction and PCR amplification have proven difficult for multiple reasons. DNA isolation techniques and commercially available kits are tested enabling efficient and rapid genetic analysis of Laboulbeniales fungi. Success rates for the different techniques on different taxa are presented and discussed in the light of difficulties with micromanipulation, preservation techniques and negative results. CHAPTER 2: The class Laboulbeniomycetes comprises biotrophic parasites associated with arthropods and fungi. -

Gareth Jones, [email protected] Abstract: Phylogenetic analyses of four nuclear genes, namely the large and small subunits of the nuclear ribosomal RNA, transcription elongation factor 1-alpha and the second largest RNA polymerase II subunit, established that the ecological group of marine bitunicate ascomycetes has representatives in the orders Capnodiales, Hysteriales, Jahnulales, Mytilinidiales, Patellariales and Pleosporales. Most of the fungi sequenced were intertidal mangrove taxa and belong to members of 12 families in the Pleosporales: Aigialaceae, Didymellaceae, Leptosphaeriaceae, Lenthitheciaceae, Lophiostomataceae, Massarinaceae, Montagnulaceae, Morosphaeriaceae, Phaeosphaeriaceae, Pleosporaceae, Testudinaceae and Trematosphaeriaceae. Two new families are described: Aigialaceae and Morosphaeriaceae, and three new genera proposed: Halomassarina, Morosphaeria and Rimora. -

Mycosphere 8 (1), 137–146, Doi 10.5943/mycosphere/8/1/13 Abstract The new family Phaeothecoidiellaceae, introduced in this paper, comprises several species which cause sooty blotch and flyspeck diseases of several economic fruits. This results in quality issues with fruits and plants, due to the black thallus and small black dots coating the surface. Most species of Phaeothecoidiellaceae are biotrophs and are unculturable without the host material, and direct-sequencing is difficult because of the very small and flattened thyriothecia. Therefore, this fungal group is relative poorly known due to limited sampling and few in-depth studies. "Microthyriales"-like taxa appearing as small black dots on the surface of mango trees were collected in northern Thailand. -
Ecological Monitoring at Rare, 2020
Ecological Monitoring 2020 rare Charitable Research Reserve Prepared by: Jordan Wrobel Jenna Quinn 1 Acknowledgements Many thanks to Colleges and Institutes Canada (CICan) Career-Launcher Internships, funded by Natural Resource’s Canada’s Green Jobs- Science and Technology Internship Program, and Employment Ontario for providing essential funding for ecological monitoring at rare; without their support, this monitoring program and report would not have been possible. I would also like to thank rare staff for assistance with monitoring and support of intellectual and professional growth. Thank you to Caroline Reisiger and Sarah Cui for their much- appreciated assistance with fieldwork and to Dr. Justin Gaudon for your support with the statistical analyses. To rare’s committed volunteers: Jacqueline Haynes, Miriam Bauman, Emma Wegener, Hilary Irving, Bethany Wakefield, and Logan Mercier; thank you so much for your support with monitoring, these programs would not be as successful without you. I would like to thank all advocates of rare Charitable Research Reserve for helping to support rare’s vision and activities. The rare Charitable Research Reserve acknowledges and is grateful to all of the original stewards of the land in which rare resides, within the Haldimand Tract, spanning six miles on either side of the Grand River from source to mouth. Understanding that this land has been rich in diverse Indigenous presence since time immemorial, there are several Indigenous Nations that we would like to mention. We would like to honor and respect the sovereignty of both First Nations in our area: the Haudenosaunee Peoples of Six Nations of the Grand River and the Anishinaabe Peoples of Mississaugas of the New Credit First Nation. -

Abdollahzadeh, [email protected]; P.W. Crous, [email protected] Abstract: The Capnodiales, which includes fungi known as the sooty moulds, represents the second largest order in Dothideomycetes, encompassing morphologically and ecologically diverse fungi with different lifestyles and modes of nutrition. They include saprobes, plant and human pathogens, mycoparasites, rock-inhabiting fungi (RIF), lichenised, epi-, ecto- and endophytes. The aim of this study was to elucidate the lifestyles and evolutionary patterns of the Capnodiales as well as to reconsider their phylogeny by including numerous new collections of sooty moulds, and using four nuclear loci, LSU, ITS, TEF-1α and RPB2. Based on the phylogenetic results, combined with morphology and ecology, Capnodiales s. lat. is shown to be polyphyletic, representing seven different orders. The sooty moulds are restricted to Capnodiales s. str., while Mycosphaerellales is resurrected, and five new orders including Cladosporiales, Comminutisporales, Neophaeothecales, Phaeothecales and Racodiales are introduced. Four families, three genera, 21 species and five combinations are introduced as new. -
