... It is unclear whether there is only the one genus Lemanea or the morphologically very similar, but vegetatively, reproductively and phylogenetically very different genus Paralemanea is also among these riverine populations. The possibility that two genera, Lemanea and Paralemanea, can occur together in the same site or in different segments of the same water body (up stream and down stream) has been documented in other regions of the world (U.S.A: Palmer 1941; Italy: Mannino et al. 2003;Czech Republic: Kucera et al. 2008;Serbia: Simić et al. 2010). In addition, physico-chemical features of inter-site differences affecting the populations and in relation to anthropgenic activities, conservation proposals and sustainable harvest methods are needed to safe guard the wild populations on a long-term basis. ...
An annotated bibliographic catalogue of Indian red algae (Rhodophyta) occurring in freshwater and estuarine habitats (moist terrestrial soils, ponds, streams, rivers, lakes, large inland brackish water lagoons and coastal estuaries), based on more than a century (1846 to 2017) of publications is presented in a single coherent work for the first time. There have been 81 taxonomic entities (species, varieties and doubtful records), distributed among 21 genera recorded for the vast Indian sub-continent. Species distribution among the 21 genera are as follows:; and Tuomeya-2. Of the seven currently recognized classes of Rhodophyta, no members of Bangiophyceae, Cyaniodiophyceae, or Rhodellophyceae are recorded from India. For each taxon, the following information is provided: (i) valid and currently accepted binomial (ii) synonyms as applicable to Indian records (iii) references with distribution in India and (iv) brief notes. Descriptions of new species based on Indian collections (holotypes) are indicated and some new combinations were made, when necessary. Several generic records (e.g., Balliopsis, Hildenbrandia, Kyliniella, Nothocladus and Tuomeya) and some species records (e.g. Batrachospermum longiarticulatum, Lemanea australis, L. catenata, L. fluviatilis, L. mamillosa, L. torulosa and Thorea hispida) warrant detailed confirmatory data based on reinvestigation of fresh collections for morphology, reproduction and particularly molecular data to confirm the presence in the country. Future collections, especially in the Indian Biodiversity Hotspots (Indo-Burma, Western and Eastern Ghats and Andaman & Nicobar Islands), may uncover the occurrence of genera such as Bangia, Cyanidium and Ne-malionopsis known to be present in neighbouring countries of Pakistan, Nepal and Thailand. Geothermal (acidic) hot water springs in India may reveal the presence of extremophilic unicellular red algal genera like Cyanidium, Cyanidioschyzon and Galdieria of the Cyanidiophyceae. Two maps showing the political and biogeographic zones of India are included. The need to preserve holotype and duplicate/voucher specimens with GPS data of future collections of red algal groups in a centralized national facility is also highlighted.
... According to morphological and reproductive characteristics, two species of Paralemanea are actually recognized in Europe: P. annulata (Kützing) Vis et Sheath and P. catenata (Kützing) Vis et Sheath [10]. They were found in a small number of localities, mainly in central and southern Europe [12], Bulgaria [13,14], Italy [15], Czech Republic [9,11,16], Spain, the Iberian Peninsula [17] and Serbia [18,19]. The details of the findings in western Europe are limited. ...
... Carmona et al. [27,28] suggested that the morphological differences are the result of adaptation to environmental conditions, especially to the rate of water. Previous studies conducted in Europe indicate that this alga was found in mountain rivers at altitudes of 1400 m in Italy [15], 700 m in Spain 17, as well as lowland-highland rivers of Czech Republic at altitudes from 214 to 497 m [9]. Based on analysis of the described environmental conditions, it is concluded that the prerequisites for the development of these algae are sunlit or partially shaded localities, a stable base, fast or moderately fast waters (higher than 35 cm/s), relatively small depth (1-60 cm), neutral or alkaline waters (pH 6.3-8.1), ...
Abstract: This paper describes the morphology, distribution and ecology of 15 populations of Paralemanea collected from 2004 to 2011 in 12 rivers in Serbia. On the basis of morphological and reproductive characteristics, two species were identified: P. annulata (12 populations) and P. catenata (3 populations). Morphological (presence of a stalk, thalli length, nodal diameter (ND), internodal diameter (ID), node and internode diameter ratio (ND:ID) and reproductive (arrangement of spermatangial sori, length and diameter of carpospores, presence of Chantransia stage) features described in the literature are generally confirmed in the populations from Serbia. True branching was observed in six populations of P. annulata in the gametophyte stage. False branching (whorled branching) occurred in five populations of both species observed. In the Pčinja (P2), Ibar (IB5) and Crnovrška rivers (CR10), the number of whorled branching was 6-11 (P. annulata). For P. catenata the number of such branching was 3-5 in the Nišava River (N8) and Sokobanjska Moravica River (SM12). False branching appears at damaged thalli, somewhat repairing it. Algae belonging to the Paralemanea genus were found at altitudes from 160 to 780 m (P. annulata), and from 240 to 400 m (P. catenata), at water temperatures ranging from 11.5 to 29°C (P. annulata) and from 12.6 to 17.4°C (P. catenata), in neutral and weakly alkaline waters, with a high level of oxygen concentration, with conductivity ranging from 70 to 433 μS/cm for P. annulata, and 260 to 440 μS /cm for P. catenata. It was also observed that P. annulata and P. catenata often grow in oligotrophic conditions and rarely in eutrophic conditions
... As has already been mentioned, findings of this red alga in Serbia were documented in the Drina River, which is characterised by cold fast-flowing water with transparency equal to the water depth. Members of the genus Lemanea require a higher current velocity in comparison with those of the genus Paralemanea (Mannino et al. 2003). Our data indicate that P. torulosa prefers fairly deep cold rivers with clean water. ...
The paper presents the first record of the freshwater red alga Paralemanea torulosa and new findings of the species Lemanea fluviatilis and Hildenbrandia rivularis in Serbia. The existence of all three species was recorded in the upper reaches of clean fast-flowing rivers and brooks belonging to the basin of the Danube River. Lemanea fluviatilis was found in the Dojkinacka River in Eastern Serbia, while Paralemanea torulosa was recorded in the Drina River and Hildenbrandia rivularis in the Cvetica Brook and Bioštanska Banja Brook in Western Serbia. These reports are important for conservation of the biodiversity of Serbia, since it is well known that freshwater red algae are endangered and rare species (taxa) in many countries. In Serbia they are under strict protection of the law. © 2017 Institute of Botany and Botanical Garden Jevremovac, Belgrade.

... Among the approximately 19-20 non-marine red algal genera known hitherto from the Indian sub-continent West 2013a, 2013b), Lemanea is reported only from Manipur state, and occurs mostly during the colder months (December to February) when harvesting, drying and packaging are done for sale in local markets Based on Vis and Sheath (1992), Sheath et al. (1996Sheath et al. ( , 2006, Carmona Jimenez and Necchi (2002), Kumano (2002), Mannino et al.

A new macroscopic riverine red algal species, Lemanea manipurensis sp. nov. (Batrachospermales) is described from Manipur in northeast India. It has a sparsely branched, pseudoparenchymatous thallus with a single, central axial filament that lacks cortical filaments. Spermatangia occur generally in isolated, low and indistinct patches or form an almost continuous ring around the axis. Carposporophytes project into the hollow thallus cavity without an ostiole. The most striking morphological feature is the carposporophyte with very short gonimoblast filaments having cylindrical, narrow and sparsely branched sterile filaments, the terminal cell of each branch with a single, large, elongate carpospore. The widely distributed L. fluviatilis has spherical carpospores in long branched chains. Phylogenetic analysis of rbcL sequence data and comparison with other Batrachospermales clearly show that our specimens do not align with other species of Lemanea and Paralemanea investigated thus far. Five specific names attributed in previous literature (1973-2014) to Lemanea from Manipur, L. australis, L. catenata, L. fluviatilis, L. mamillosa, and L. torulosa are rejected until critical anatomical and molecular evidence is available for specimens from the Manipur river systems. Taxa referable to Paralemanea were not confirmed for India in this study. In view of the high demand for food and medical uses of L. ma-nipurensis in northeast India, conservation measures are needed for its long term survival. The present paper constitutes the first combined morphological / molecular study on a freshwater red alga from India.
This is the first contribution to the cryptogamic flora (algae, bryophytes, fungi and lichens) of
the “Bosco Pomieri”, an old-growth forest included in the Madonie Regional Park (N-Sicily).
This area presents a significantly high biodiversity (41 algae, 41 bryophytes, 141 fungi, and 105 lichens) and also hosts several taxa of high biogeographic value.
