Based on collections by the author made in September 2001, Conocephalum salebrosum, Hydrogonium ehrenbergii, Breutelia chrysocoma and Campylopus pilifer var. brevirameus are reported as new to the Azores. Seven species are reported as new to Sâo Miguel. Various notes and keys are provided for several taxa.

Aneura maxima is a species which was described from Java and reported from various parts of Asia (India, Indonesia, New Caledonia and Japan). It was recently found new to Thailand (Frahm et al. 2009). Schuster (1992) reported this species from the Appalachian Mountains in North America and Andriesen et al. (1995) for the first time for Europe from the Belgian Ardennes. I (Frahm 1997) reported the species a second time for Europe from Finland. Subsequently, the species was reported from many other regions of Europe including Denmark (Thingsgaard 2002), Poland and Luxemburg (Werner 2003), Corsica (Ros et al. 2007), France (Sotiaux et al. 1996), Czechia (Kucera 2004) and Germany (Meinunger & Schröder (2007).

India is among of the 12 mega biodiversity countries in the world. The huge area and the range of phyto-climatic conditions met within its eight bio-geographical zones contribute to the great diversity of the Indian flora. These bio-geographical zones have diverse topographical variations and climatic conditions. The present work deals with the bryo-diversity of western part of the country which is greatly neglected due to its comparatively harsh environmental conditions by the bryologists. It is an attempt to provide a comprehensive account of the bryophyte wealth of the region by stepwise exploration and it has initiated with Ranthambhore National Park.

An account of 40 species of bryophytes including 24 mosses and 16 liverworts of Kakkavayal Reserve forest in the Western Ghats is provided here. This includes four new records of phytogeographical significance to Kerala viz., Cololejeunea appressa (Evans) Benedix, C. follicola Srivastava & Srivastava, C. udarii Asthana & Srivastava and Pallavicinia himalayensis Schiffn.

The checklist reports total 2489 taxa of bryophytes recorded from India, comprising 1786 species in 355 genera of mosses, 675 species in 121 genera of liverworts and 25 species in six genera of hornworts. Some of the genera of mosses like Fissidens, Barbula, Campylopus, and Bryum are found to have largest number of species. In liverworts Riccia, Porella, Frullania, Lejeunea, Plagiochila and Jungermannia are recorded to be species rich genera and in hornworts Anthoceros is well represented by species. Pottiaceae, Lejeuniaceae and Notothyladaceae are largely represented in India. Nearly 340 species are endemic to India.

Contribution to the bryophyte flora of India: the Parambikulam Tiger Reserve in the Western Ghats
(2011)
A checklist of the bryophyte flora of the Parambikulam Tiger Reserve in the Western Ghats is presented here. It consists of 58 taxa (39 mosses, one Hornwort and 18 liverworts), of which Grimmia funalis and Thuidium subdelicatulum has reported as new record for India (Manju & Rajesh, communicated), Leucophanes glaucum (Schwägr.) Mitt. is newly reported for the mainland of India, 10 species are newly reported for Peninsular India and another four are new for the Kerala State.

The status of endemic liverworts in the Western Ghats ‘one of the major Hot spots’ of plant biodiversity have been discussed in the present paper. The study is based on the evaluation of type and authentic specimens available in Lucknow University Hepatic Herbarium (LWU) as well as those in several international herbaria including NICH, NY, JE, FH, G and excicatae of the world and published data. An overall assessment and evaluation revealed the presence of a total of 54 liverworts endemic to Western Ghats in India. The paper also discusses those species which were earlier known as endemic to the area but now show an extended range of distribution elsewhere and also the species earlier introduced from Western Ghats but now changed their status.

During a fieldtrip to Hordaland in Norway, I collected Fissidens serrulatus in one place: Norway, Hordaland, Skanevik, steep slope along road between highway E 134 and village, birch forest, on seeping rocks of a cliff, ca. 90 m alt. leg. Frahm Sept. 1, 2011, no. 2011676. The specimen was collected because of the large size of the plants and to check, whether they belong to F. adianthoides or F. dubius. In fact, F. serrulatus looks much alike these species mentioned, also under the microscope, showing a pale band of cells along the leaf margins, but differs under the microscope by strongly mamillose laminal cells (fig. 3).

The aqueous extract of Dumortiera hirsuta (Swaegr.) Nees, a bryophyte, was found to be effective against seven postharvest phytopathogens tested. The fungitoxicity of the extract was measured by percent spore germination inhibition and percent radial growth inhibition using poisoned food technique. The inhibition of spore germination by the Dumortiera extract was within the range of 400 to 550 ppm. In poisoned food technique, out of seven postharvest phytopathogenic fungi tested six were completely inhibited by the Dumortiera extract with concentration range of 550 to 600 ppm. The mode of action of extract (350 ppm) was examined in the case of Aspergillus niger van Tieghem. Distinct morphological changes were observed in treated hyphae in comparison to control . The treatment clearly showed anomalies in the hyphae; cell wall of became flaccid, cytoplasm started leaving the cell wall and became granulated.
