TL;DR: Two new genera and four new species in three orders of Dothideomycetes gathered from dead twigs of Dodonaea viscosa in Honghe, China are presented, suggesting high fungal diversity in the region and the existence of numerous species awaiting discovery.
Abstract: Members of Dodonaea are broadly distributed across subtropical and tropical areas of southwest and southern China. This host provides multiple substrates that can be richly colonized by numerous undescribed fungal species. There is a severe lack of microfungal studies on Dodonaea in China, and consequently, the diversity, phylogeny and taxonomy of these microorganisms are all largely unknown. This paper presents two new genera and four new species in three orders of Dothideomycetes gathered from dead twigs of Dodonaea viscosa in Honghe, China. All new collections were made within a selected area in Honghe from a single Dodonaea sp. This suggests high fungal diversity in the region and the existence of numerous species awaiting discovery. Multiple gene sequences (non-translated loci and protein-coding regions) were analysed with maximum likelihood and Bayesian analyses. Results from the phylogenetic analyses supported placing Haniomyces dodonaeae gen. et sp. in the Teratosphaeriaceae family. Analysis of Rhytidhysteron sequences resulted in Rhytidhysteron hongheense sp. nov., while analysed Lophiostomataceae sequences revealed Lophiomurispora hongheensis gen. et sp. nov. Finally, phylogeny based on a combined dataset of pyrenochaeta-like sequences demonstrates strong statistical support for placing Quixadomyceshongheensis sp. nov. in Parapyrenochaetaceae. Morphological and updated phylogenetic circumscriptions of the new discoveries are also discussed.

TL;DR: The Duviesia rust represents a previously unknown genus, described here as Bibulocystis gen. viennotii, the sixth rust genus with hygroscopic teliospore cysts and the fourth recorded in Australia, with Kernkampella, Ravenelia and Uromycladium.
Abstract: The five known genera of Uredinales with hygroscopic teliospore cysts, Cystomyces, Kemkampella, Ravenelia, Spumula and Uromycladium, are discussed. Of these, the monotypic Cystomyces, type species C. costaricensis, is the only one with teliospores composed of a simple, monohyphal pedicel attached to cysts, which bear the fertile cells. A rust of Daviesia species in south-eastern Australia was thought originally to be an undescribed species of Cystomyces. Type material of C. costaricensis has been studied. Whereas Cystomyces has teliospores borne on percurrently proliferating sporogenous cells and three, dark-walled fertile cells with apical germ slits, the Duviesia rust has teliospores borne on sympodially proliferating sporogenous cells and four, palewalled fertile cells, each with an apical germ pore. Its teliospores show a complex arrangement of cysts and fertile cells, which is described and illustrated. These and other differences indicate that the Duviesia rust represents a previously unknown genus, described here as Bibulocystis gen. nov., type species B. pulcherrima var. pulcherrima. A single collection from the Central Tablelands of NSW with smaller, often irregular, teliospores is described as B. pulcherrima var. monticola. Only pycnia and telia are known for the two varieties. An emended description of the genus Cystosnyces is given. The full-cycled rust of Albizia from New Caledonia described as Dicheirinia viennotii is compared with original material of the type species of Dicheirinia, D. binata. Whilst Dicheirinia has teliospores with ornamented fertile cells borne on sterile cells, teliospores of the Albizia rust have smooth fertile cells borne on hygroscopic cysts. As its teliospores closely resemble those of the Australian Daviesia rusts, it is transferred as Bibulocystis viennotii. The characteristics and taxonomic position of the other 11 species currently placed in Dicheirinia are summarised briefly. Bibulocystis is the sixth rust genus with hygroscopic teliospore cysts and the fourth recorded in Australia, with Kernkampella, Ravenelia and Uromycladium.

...The two remaining genera, Cystomyces and Spumula, are unknown in Australia, although at least one species of Spumula, S. caesalpiniae (Boedijn 1959) on Caesalpinia nuga (L.) W.T. Aiton, occurs just north of Australia, in the Sumatra province of Indonesia....

TL;DR: The phylogenetic relationships between 79 specimens of Uromycladium were determined based on a concatenated dataset of the Small Subunit, the Internal Transcribed Spacer and the Large Subunit regions of nuclear ribosomal DNA, and the mitochondrial cytochrome c oxidase subunit 3.
Abstract: Uromycladium tepperianum has been reported on over 100 species of Acacia, as well as on the closely related plant genera, Falcataria, Racosperma and Paraserianthes. Previous studies have indicated that U. tepperianum may represent a complex of host-specific, cryptic species. The phylogenetic relationships between 79 specimens of Uromycladium were determined based on a concatenated dataset of the Small Subunit, the Internal Transcribed Spacer and the Large Subunit regions of nuclear ribosomal DNA, and the mitochondrial cytochrome c oxidase subunit 3. This study showed that the host range of U. tepperianum s. str. was restricted to species of Acacia in the 'A. bivenosa group' sensu Chapman & Maslin (1992). An epitype of U. tepperianum on A. ligulata is designated to create a stable taxonomy for the application of this name. Sixteen novel species of Uromycladium are described, based on host preference, morphology and a phylogenetic species concept.

TL;DR: Cross inoculations using basidiospores and aeciospores confirmed the macrocyclic, autoecious nature of the life cycle in both rust populations and showed that the two populations were distinct in their host specificity.
