A new lichen species <i>Usnea christhinae</i> Bystrek is described from the Patagonia Andes, the reserve upon lake Onelli in the National Park Los Glaciares. It belongs to subgenus <i>Protousnea</i> Motyka emend. Bystrek and is closely related to <i>U. cavernosa</i> Tucker.

Abstract This paper presents new records of 180 lichen species from Bolivia; 103 are new national records. Three species, Bryonora curvescens (Mudd) Poelt (also from Ecuador), Lepraria elobata Tønsberg and Pyrenula laetior Müll. Arg., are reported for the first time from the Southern Hemisphere, and five, Bathelium aff. sphaericum (C. W. Dodge) R. C. Harris, Lepraria jackii Tønsberg, Psiloparmelia arhizinosa Hale, Szczawinskia tsugae A. Funk and Trinathotrema lumbricoides (Sipman) Sipman & Aptroot, are new to South America. To complement the rather poorly recognized distribution of some species, five of the taxa reported here are also new to Ecuador. Notes on distribution and chemistry are provided for most species, and some, especially those belonging to taxonomically critical groups, are discussed in greater detail.

Alpinalona gen. nov. is described for two species found in high altitude localities of continental North America and South America: Alona manueli (Sinev & Zawisza, 2013) from the Neovolcanic Mexican Axis and Alpinalona cajasi gen. et sp. nov from El Cajas National Park (Ecuador). The new genus is separated from Hexalona and allies by the absence of limb VI and filter plate V;  from Anthalona, Coronatella and the elegans-group by having seven setae on exopodite III, and by the presence of a well-developed seta 1 on the IDL of limb III; from Alona s. str. (quadrangularis-group) and Ovalona, by two main head pores, lateral head pores located close to main pores, and by a bilobed exopodite V; from Ovalona by the presence of seta (i) and inner setae 2–3 on limb I, and setae 4–5 of exopodite III being of same size; and from Alona s. lato by weakly developed marginal denticles of postabdomen, clusters of thin setulae on ventral surface of limb I, and by plumose setae 5–6 of exopodite IV. Alpinalona cajasi sp. nov. can be easily distinguished from A. manueli by the following characteristics: prominent posterodorsal angle of carapace; broader headshield; longer PP distance; and postanal marginal denticles organized into groups.

Rhagomys longilingua is one of the rarest sigmodontine rodents of South America, currently known from only 2 localities (4 individuals) in Peru and Bolivia. Here we report 3 additional localities in Peru, one of which extends the geographic distribution range of this species 613 km northeast from the type locality (Suecia, Manu National Park, Cusco department). Potential distribution models showed the presence of R. longilingua from Bolivia until Colombia along the eastern slope of the Andes.

A relatively large and established population of Houttuynia cordata from Itatiaia National Park in Brazil represents the first record of naturalized Saururaceae in South America. Although the species is potentially invasive, unknown mechanisms have prevented its spread to other localities between 1940, when it was recorded in cultivation in Brazil, and the present. The nearest known naturalized population is situated 5,600 km away, in Costa Rica, Central America.

The paper presents the first data on lichen diversity in the Kenozersky National Park (Arkhangelsk Region, Northwest Russia). As a result of the study, 263 species and 1 subspecies of lichens and allied fungi were found in the southern part of the national park. Seventeen lichen species are reported for the first time for Arkhangelsk Region. Biatora albidula is a new species for Northwest European Russia. Two recorded species are included in the Red Data Book of Russian Federation and 7 in the Red Data Book of Arkhangelsk Region. Pycnothelia papillaria can be recommended for inclusion to the Red Data Book of Arkhangelsk Region.

We describe a new species of Enyalioides from a mid-elevation premontane forest in central Peru. This represents the seventh species of Enyalioides known to occur east of the Andes in South America; the other six species are E. cofanorum, E. laticeps, E. microlepis, E. palpebralis, E. praestabilis, and E. rubrigularis. Among other characters, the new species is distinguished from other Enyalioides by the combination of an orange blotch on the antehumeral region (in adult males), 30 or fewer longitudinal rows of dorsals in a transverse line between dorsolateral crests at midbody, ventral scales strongly keeled, and caudal scales heterogeneous in size on each autotomic segment. The new species is most similar morphologically to E. cofanorum and E. microlepis.

The name Isoetes pedersenii H.P. Fuchs (Lycophyta), a species known only from the Mburucuyá National Park, Corrientes, Argentina, is validated. Observations were carried out on herbarium material with stereoscopic, light and scanning electron microscopes. The species is described and typified. A diagnosis and discussion about its distribution and its relationship with the morphology of other species of Isoetes are provided.
