Results of bryoindication mapping based on calculation of an index of atmospheric purity (IAP) of towns of the Left Bank Ukraine, i.e. the smallest Romny (Sumy oblast) and Myrhorod (Poltava oblast) towns, small Pryluky (Chernihiv oblast) and Lubny (Poltava oblast) towns as well as medium size Poltava town (Poltava oblast), are provided. It is found that isotoxic bryoindication zones of moderately polluted air are predominate and often forming entire areas in the centre / industrial / densely built-up areas of Poltava, Lubny and Pryluky towns while isotoxic zones with slightly polluted or unpolluted air are predominant or more widely distributed in smaller towns Romny and Myrhorod. Correlation of data on species diversity, community composition of bryophytes as well as data of the IAP zoning of the territory of all towns mentioned as well as natural conditions of their territory and anthropogenic pressure is discussed.

This is the second manuscript about a series of papers dedicated to study the flora of Los Farallones de Cali, an Andean natural region in Colombia. The general purpose is to make an inventory of plants, algae and fungi by studying different locations in Los Farallones. This paper deals with aroids (Araceae family), from a low montane forest at Pico de Águila (Valle Department, Colombia). Data about altitudinal and geographical distribution in Colombia of aroids found are presented here, along with some drawings for facilitating field identification.

The genus Diplasiolejeunea is added to the liverwort flora of India from the Kerala part of the Western Ghats reporting two species: Diplasiolejeunea cavifolia Steph. and D. cobrensis Gottsche ex Steph. The genus is known from tropical Asia with eight species. Among them Diplasiolejeunea cavifolia is widespread, but still the genus was not yet recorded from India.

Solanum

(Solanaceae) comprises cultivated and wild plants with 1400 species in the world and 14 species in Iran. Solanum is a taxonomically complex genus due to morphological similarities, phenotypic plasticity and hybridisation. Limited studies were done on anatomical features of this important genus. In this project, 10 native and exotic species of Solanum in Iran belonging to two subgenera were examined anatomically. Leaf mesophyll and midrib and indumentum were analysed using light microscope. Hand-made cross section method and Toluidine blue as colouring agent were used. Characters as length and width of main vascular bundle, thickness of collenchyma, trichome density, thickness of parenchyma strand, thickness of lamina and length and shape of midrib were diagnostic features among species studied. In UPGMA tree and PCA ordination, species of two subgenera were separated from each other. Results of this study confirmed the taxonomic importance of anatomical characters in Solanum species studied.

This work presents research materials, the purpose of which is to grow seedlings of coniferous trees in the open field using artificial substrates of mycorrhizal macromycetes in forest nurseries of Central, North and Northeast Kazakhstan. The success of mycorrhiza formation in seedlings Pinus sylvestris and Picea obovata from forest nurseries of Akmola and Karaganda regions, and the survival rate of seedlings from forest nurseries of Akmola, Karaganda and Pavlodar regions of Kazakhstan are analysed. In the future, we want to expand the range of studied species and compare artificially mycorrhized seedlings with naturally mycorrhized species from natural forests. If we compare the survival rate of seedlings in nurseries, the highest in P. sylvestris seedlings in Shaldai is about 78%, low in Novodolenskoe, about 27%, and for P. obovata, on average, 66%. In the future, we want to expand the range of studied species and compare artificially mycorrhized seedlings with naturally mycorrhized species from natural forests.

Sphinctrina pertusa Falswal A. is described as a new species of lichenicolous fungus from India. It is characterised by eight non-septate, broadly ellipsoidal, uniseriate, ascospores with olive green tint and irregular ridge like ornamentations. This fungus is growing on known lichen host Pertusaria but differs from five closely related species i.e., S. anglica, S. leucopoda, S. tubaeformis, S. turbinata, S. paramerae with different taxonomic characters. A detailed comparative analysis with non-septate closely related species is provided.

A liverwort collection by Bence Pócs from the Venezuelan Guayana resulted in 31 species of liverworts, including Cololejeunea bencei new to science and C. cardiocarpa, C. obliqua, C. platyneura, C. schusteri, C. verwimpii, Lejeunea pulchra and Plagiochila crispabilis new to Venezuela. The distribution and differentiation of C. schusteri is discussed.

The present paper interprets a new species and a new record of the lichenicolous fungus Pyrenidium from India. The new species P. dimelaenae Y. Joshi was found on the thallus of saxicolous lichen species Dimelaena oreina (Ach.) Norman and is characterised by globose to subglobose black perithecia with light greenish blue tint in ostiolar channel. The new species shares many morphological characters with other Pyrenidium species but differs in its number of spores and hosts. In addition, two new records, i.e. Lichenostigma dimelaenae Calat. et Hafellner and P. borbonicum Huanraluek, Ertz et K. D. Hyde are also being reported from India for the first time.

Two lichen species, Variospora kudratovii and Zeroviella laxa, and a lichenicolous species, Polycoccum clauderouxii are reported for the first time from Pakistan and represent first generic records as well. Detailed macro- and micromorphological descriptions and spot test results are provided along with ITS-based molecular phylogenetic analysis.
