Abstract The paper provides data on 21 Caloplaca Th. Fr. species from central European Russia. Two species are new for Russia: C. atroflava (Turner) Mong. s.l. and C. soralifera Vondrák & Hrouzek. A further seven are new for European Russia [C. flavocitrina (Nyl.) H. Olivier, C. inconnexa (Nyl.) Zahlbr., C. marmorata (Bagl.) Jatta, C. oasis (A. Massal.) Szatala] or central European Russia [C. dichroa Arup, C. interfulgens (Nyl.) J. Steiner, C. monacensis (Leder.) Lettau]. Short taxonomic notes together with information on habitat and distribution are provided for the newly recorded species. An additional twelve Caloplaca species recognized in the area are also briefly presented.

Abstract A synopsis of the genus Orchidotypus Kraenzl. in Colombia is presented. Morphological descriptions of all national representatives of the genus are provided, together with information about their habitat, ecology and general distribution, detailed illustrations of the studied plants, and an identification key for Colombian Orchidotypus species. A new species discovered during these studies is described and a new generic combination is proposed.

Abstract A new species of Microchilus Presl, M. campanensis Kolan., is described from Panamanian material and illustrated. The new species differs from M. pedrojuanensis Ormerod in its spur shape, prominent epichile apical lobe, prominent floral bracts, and irregular apical margins of the petals and dorsal sepal. Information about its habitat and conservation status is provided.

Abstract . Two new species of Scaphyglottis Poepp. & Endl. from Colombia are described, illustrated and placed within a key for determination of Colombian Scaphyglottis species. The taxonomic affinities of each species are briefly discussed and information about their distribution and ecology is given.

Abstract Septotrapelia usnica (Sipman) Kalb & Bungartz is reported as new for West Africa from Togo. Its taxonomy, distribution and habitat requirements are discussed. Notes on other usnic acid-containing leprose species are presented.

Abstract A new species of Cleistes Lindl., C. lehmannii is described and illustrated based on Colombian material. The taxonomic affinities of the new entity are briefly discussed. The species is placed within a key to identification of the national representatives of the genus.

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.

Abstract Based on fieldtrips of the authors in 2012, a list of species collected in a small area of the Western Ghats (Coorg District, state of Karnataka) is presented. It includes 18 species of liverworts and hornworts as well as 76 species of mosses. 27 species of mosses are newly reported for the state of Karnataka, 6 species are new for Coorg province. Holomitrium javanicum Dozy & Molk. is reported as new to India. Campylopus sedgwickii Dix. described from Sri Lanka and so far only known from the type locality is a new synonym of C. recurvus Mitt. The list gives a rough inventory of the bryoflora in altitudes between 900 m and 1750 m and can be regarded as typical for the northern Western Ghats.

Abstract Up to the mid 20th century, Callicladium haldanianum (Grev.) H. A. Crum had been known from scattered localities, but since the 1990s the number of localities of this moss seems to have increased. At present it is a frequent or common species in eastern, central and southern Poland, whereas in the northwestern and western parts its localities have distinctly decreased in number. It is known from 209 ATMOS grid squares in total. Its highest locality, at 1407 m a.s.l., is in the Tatra Mts, and the lowest one is almost at sea level on the Hel Peninsula. The overwhelming majority of specimens were observed on logs and stumps. This species is frequently fertile, and about 70% of the herbarium specimens were collected with sporophytes, which often were profuse. It is not threatened in any part of Poland. A map of the current distribution of C. haldanianum in Poland is included.
