The grass Agropyron tsukushiense var. transiens is native to Far East Asia, and Hordeum compressum is native to southern South America. They were found to be susceptible to all the races that they were tested to of the following: loose smut of wheat (Ustilago tritici): loose, covered, and false loose smut of barley (U. nuda, U. hordei, and U. nigra); loose and covered smut of oats (U. avenae and U. kolleri); and head smut of grasses (U. bullata). The two grasses are the first known common hosts for these smuts and will be used to study the relationships between these pathogens.

Taxonomy and nomenclature of several taxa related to Oxybasis glauca (≡ Chenopodium glaucum, Chenopodiaceae) are discussed. New nomenclatural combinations, i.e. O. ambigua (≡ C. ambiguum), O. amurensis (≡ C. amurense), and O. parodii (≡ C. parodii), are validated for three species native to Australasia (mainly Australia and New Zealand), East Asia (Russian Far East), and South America (Argentina), respectively. Information on type specimens is updated; in particular, it is demonstrated that the name Blitum rubrum var. hypoleucum was applied by Spegazzini to two species now recognized as O. parodii and O. macrosperma, but its newly designated lectotype belongs to O. parodii. It is concluded that the worldwide diversity of the O. glauca aggregate remains underestimated and further integral studies are needed for revealing taxonomic and geographic patterns in the group, and for reflecting them in updated taxonomy.

The first lichenological inventory in Koryakia has resulted in the list of 315 species reported from Parapolsky Dale, within and in vicinities of the Koryak State Reserve. Altogether 46 species are published from the Kamchatka Territory for the first time, including Lecanographa grumulosa new to Russia, East Asia and Beringia; Cercidospora trypetheliza, Lecania dubitans, Pertusaria borealis, Piccolia ochrophora, Protoparmelia cupreobadia, Rimularia badioatra and Strangospora moriformis new to Russian Far East; Abrothallus bertianus, Cladonia strepsilis, Physciella melanchra, Rimularia badioatra, Sclerococcum parasiticum, Sphinctrina leucopoda and Strangospora moriformis new to Beringia. The lichen diversity of the study area is relatively poor due to natural reasons. Comparison with neighboring regions (Kamchatka Peninsula, Chukotka, Magadan Region, Yakutia and Alaska) shows that the lichen flora of Parapolsky Dale contains almost no specific species. The majority of the species recorded here are also known from neighboring regions, especially Alaska and Kamchatka Peninsula.

Tersilochines of South, Southeast and East Asia (excluding Mongolia and Japan) have been studied. Eight genera and 60 species are recorded in the region: Allophrys (2 species), Barycnemis (5 species), Diaparsis (29 species), Phradis (2 species, including 1 unidentified species), Probles (12 species, including 1 unidentified and 6 undescribed species), Sathropterus (2 species), Slonopotamus gen. nov. (2 species) and Tersilochus (6 species, including one species of the obscure status). One genus and 26 species are described as new: Allophrys bruneiensis sp. nov. (Brunei), A. occipitata sp. nov. (Vietnam, India), Diaparsis absista sp. nov. (Brunei), D. bannapeana sp. nov. (Laos), D. bolikhamsaica sp. nov. (Laos, Thailand), D. brunnea sp. nov. (Brunei), D. crenulator sp. nov. (Brunei), D. dediticia sp. nov. (Vietnam, Brunei), D. hilaris sp. nov. (Vietnam), D. karnatakana sp. nov. (India), D. labiensis sp. nov. (Brunei), D. mandibulator sp. nov. (Laos), D. minuta sp. nov. (Vietnam), D. monstrosa sp. nov. (Brunei), D. morleyi sp. nov. (Sri Lanka), D. propodeator sp. nov. (Brunei, Sarawak State of Malaysia, southern Indonesia, Laos), D. pulchra sp. nov. (South Korea), D. sarawakiensis sp. nov. (Sarawak and Pahang states of Malaysia), D. viela sp. nov. (Vietnam, Laos), D. vietnamica sp. nov. (Vietnam), D. zispina sp. nov. (Vietnam), Probles vietnamica sp. nov. (Vietnam, probably East China and south of Far East of Russia), Sathropterus secundus sp. nov. (Vietnam), Slonopotamus elephantoides sp. nov. (Laos), S. indianus sp. nov. (India) and Tersilochus granulatus sp. nov. (South Korea). Generic assignment of two species are changed: Barycnemis sanctijohanni (Rao & Kurian, 1951), new combination, and Probles (Microdiaparsis) caudate (Morley, 1913), new combination. Barycnemis dissimilis and B. tobiasi from Nepal, Diaparsis convexa from Vietnam, D. niphadoctona from Laos, and Sathropterus pumilus from India and Nepal are newly recorded from the countries. The genus Diaparsis comprises almost half of species of the tersilochine fauna of the studied region (29 species, 48%), and is a dominant genus in the Oriental Region. Keys to genera and species of Tersilochinae of South, Southeast and East Asia (excluding Mongolia and Japan) are provided.

AbstractAspiciliopsis macrophthalma, Placopsis fusciduloides, P. gelidioides and P. tararuana are reported for the first time from southern South America. New records for 13 species of Placopsis in southern South America are reported, and a revised key to 22 species of Placopsis and A. macrophthalma in the region is given.
