1. A new species of Poronia from India

Authors: Hembrom ME, Parihar A, Das K

Recieved: 29 August 2013, Accepted: 23 September 2013, Published: 10 October 2013

A new species: Poronia radicata,collected from the historical Aacharya Jagadish Chandra Bose Indian Botanic Garden, Howrah, India is described and illustrated. This species can be characterized by long underground branched rooting base, terminally branched stromata, capitate with an expanded and flattened stromatal disc, absence of paraphyses and apical germ pore (at maturity) and comparatively small sized ascospores with rounded germ pore. Its comparison with the allied species is also mentioned in the present paper.

2. Sex: a welcome frontier in truffle cultivation

Truffles are one of the most highly prized of all fungi. Recent advances and genetic studies have furthered our understanding of the mode by which these fungi reproduce. The understanding that some truffle species require a mating partner in order to produce fruiting bodies leads to many questions and opportunities in truffle cultivation. Here, a summary and analysis of the most recent work is presented. The potential applications of this understanding are discussed along with proposals for in-field modifications to improve the truffle yields of plantations.

Keywords: Cultivation – heterothallic – plantation – Tuber melanosporum

Rapid and precise species identification of plant pathogens such as Colletotrichum is essential for their effective control. Colletotrichum species have been traditionally identified based on conidial morphology and host-specificity. Recently, extra emphasis has been placed on DNA sequence comparison for rapid and accurate identification. In this study, we have analyzed the suitability of using internal transcribed spacer (ITS)/ 5.8S rRNA gene, which is the universal fungal barcode marker towards accurate identification of Colletotrichum species. We have sequenced 207 isolates of Colletotrichum and compared their ITS/ 5.8S rRNA gene-sequence data with that of the 183 reference sequences available for the 143 accepted Colletotrichum type strains. The results of phylogenetic analysis based on ITS/ 5.8S rRNA gene-sequence dataset along with sequence-comparison hints at the nomenclatural ambiguity of many isolates, which were initially diagnosed based on morphological characters. A local-BLAST analysis of the 588 GenBank sequences from India shows that 79% of the sequences were erroneously named and 97% of the 159 isolates procured from Indian culture collection centres were found to be misidentified. Mycologists need to work on identification of a potential secondary barcode for this genus as ITS/ 5.8S rRNA is found to be ineffective in accurate identification of Colletotrichum. Researchers should also follow a polyphasic approach for species identification, which would definitely not be rapid; nevertheless would be more reliable and accurate.

4. Lichens of Gujarat state, India with special reference to coastal habitats

Authors: Nayaka S, Ingle KK, Bajpai R, Rawal JR, Upreti DK, Trivedi S

Recieved: 02 August 2013, Accepted: 19 November 2013, Published: 05 December 2013

The present communication reports 39 lichen species from Gujarat state, belonging to 23 genera and 13 families. The lichens were collected mostly from 10 coastal districts of the state. A total of 21 species are new additions to the lichen mycota of Gujarat while 11 partially identified species are expected to be new to science. The paper emphasizes the uniqueness of coastal habitats in terms of interesting lichen mycota.

Keywords: biodiversity – coastal area – lichenized fungi – mangrove
