Preface Mycology is one of the oldest known subjects of science dealing with fungi, a very different kind of organisms which are neither plant nor animal but belong to a separate kingdom Mycetae. Fungi have such a fascinating world of microorganism that creates curiosity and attraction among the scientific community. Fungal world embodies diversified groups of organisms which colonize, multiply and survive in nature on many macro and micro-ecological niches and substrates. Fungi are eukaryotic, achlorophyllous, filamentous or unicellular heterotrophic living organisms and are ubiquitous in distribution. Of the estimated 1.5 million species of fungi, more than 98,000 fungal species have now well been described. The utilization and application of fungi by mankind has a long and varied history. They play an important role in biodegradation, recycling of organic matter, pharmaceutical industries, agriculture, medicine, industry, bioremediation, waste management and other activities. It is true that hardly any day passes when we are either harmed or benefited by these organisms. Microbes, including fungi, constitute an important component of biodiversity and comprise one of the biggest kingdoms in the living world. As there are more than 1 lac species of fungi known which grow and multiply in all diverse habitats in nature. But unfortunately, a little attention has been paid to these organisms. Uses of fungi for mankind has broadened and grown considerably during in the last century. A well known example of this includes the discovery and production of antibiotics and wider utilization of fungi in the food industry, where they are used in the production of various compounds, hormones and enzymes for food processing. The association of many fungi with plants has resulted in their use in agriculture as both biological control agents against plant disease and as plant growth stimulants such as mycorrhizal inoculants. This has now also become a part of biotechnology as well as biochemistry. Therefore, their management, conservation and exploitation for the betterment of mankind is must. Though there are many national and international Journals that bring out information about fungi and microbes, but almost in scattered state. It is quite desirable to keep all these in a book/ monograph at one place to provide more information about mycological progress especially being done in different corners of India. Therefore, the recent mycological work into a monographic shape is a time demand for the benefit of various persons engaged in the field of mycology in India and abroad.

vi In this endeavor we have tried to accommodate the articles devoted to different aspects of mycological progress. It is our humble attempt to bring out an edited monograph titled Contribution to the Mycological Progress. It is an excellent collection of 30 original research/review articles of eminent mycologists and active researchers from different parts of India including Nepal. We hope that this monograph would be very useful to all scientists, teachers, students and readers whosoever is interested on mycology and mycological literature. A line of critical comment on this book is always welcome from the readers/ users of this book. We wish to express our sincere gratitude to all the contributors of the articles for this book to achieve our objectives. We are thankful to our colleagues Prof. Uma Palni, Prof. Neerja Pande, Dr. Y. S. Rawat, Dr. Lalit Tewari, Dr. Kiran Bargali and Dr. Susma Tamta. We are also grateful to Miss Savita Joshi, Dr. Pratibha Arya, Dr. Kapil Khulbe and many other well wishers for their active assistance time to time. We would also like to thank the publisher, Daya Publishing House, New Delhi, for bringing out the monograph timely. S.C. Sati M. Belwal

Microbes: Diversity and Biotechnology (2012) Pages 1 36 Editors: Prof. S.C. Sati & Dr. M. Belwal Published by: DAYA PUBLISHING HOUSE, NEW DELHI Chapter 1 The Black Mildews Tropical Botanic Garden and Research Institute, Palode 587 116, Thiruvananthapuram, Kerala V.B. Hosagoudar ABSTRACT The present paper deals with a exhausting account on the Black or dark mildews, foliicolous fungi distributed over two orders namely. Microthyriales and Meliolales with a number of families. These fungi flourish well in tropics and have extended their distribution to subtemperate to temperate regions of the world. Since these fungi do not cause any appreciable pathogenicity on the staple food producing crop plants, attention has not been paid much to this group. Economically, like other biotrophs, these fungi increase the temperature in the areas covered by the black colonies, initiate more respiration, reduce the efficiency of the chlorophyll, reduce total sugar, etc. The whole description is categories on their hosts and complete list of black mildews is enumerated. Keywords: Foliicolous fungi, Meliolales, Black mildews. Introduction Fungi are heterotrophs and absorb prepared food from different sources. Depending upon the source of absorption and association with its partner or associated substratum, they are classified as saprophytes, parasites and symbionts. Parasites obtain nutrients partly or fully from the living tissues of another organism. The parasites which are totally dependent on living organisms are called obligate parasites. The parasites which feed both on living and non-living organisms are called facultative or opportunistic parasites or saprophytes. Hence, the obligate parasites have to adjust and modify themselves with their partners for their survival. Certain obligate parasites kill the host tissues either by producing toxins or enzymes and then absorb nutrients from the hosts. These are called necrotrophs (necros-death, trophy-feeding). Certain parasites absorb nutrients from the living tissues, without killing them, by the specialised organs like appressoria, haustoria or nutritive hyphae. These are called biotrophs (bio-life, trophy- feeding). Fungi differ in their morphology, ecology, life history
