Fungi are small, generally microscopic, eukaryotic, usually filamentous, branched, spore-bearing organisms that lack chlorophyll. Fungi have cell walls that contain chitin and glucans (but no cellulose) as the skeletal components. What is Phylogenetic Classification? A classification based on the evolutionary relationships is known as Phylogenetic classification . A taxon (plural; taxa) is any category of classification. IMPORTANCE Although classification can be done on the basis of any criteria but classifying on the basis of phylogenetic relationships aid us �   in understanding the evolutionary changes and �   allow one to make prediction on the basis of what is known about an organism and its close relatives. Traditional Classification of Fungi u   In the 2 kingdom system of classification , fungi were placed under kingdom Plantae . Modern Classification of Fungi u   According to Hawksworth et al ., 1995 and Alexopoulos and Mims, 1979: The organisms once consid...

Fungi and fungi like organisms (FLOs) such as Pythium and Phytophthora collectively cause more diseases in the plants then do rest of the pathogen as a whole. More than 10,000 species of the fungi and FLOs are known to be pathogen to plants . The diseases caused by the fungi are so numerous and widespread that they are found all over the world and throughout all the seasons. Cercospora leaf spots of Bauhinia variegata   Symptom is defined as the changes brought about in the plant as a result of interaction of the plant, the pathogen and prevailing environmental conditions. Sign , compared with symptom, is the pathogen seen on the host plant. Symptoms caused by fungal pathogens mainly differ from the symptoms by rest of the pathogens. These symptoms can be broadly categorized as following depending upon the processes involved in the appearance of disease symptoms on the host. Necrotic Symptoms Abnormal growth and development of plant tissues Other Symptoms 1. NECROTIC SYMPTOMS T...

INTRODUCTION   This article emphasises on the classification of the Fungi and Fungi-like organisms (FLOs) into phyla of a single kingdom Fungi. But the approach here is different from others; since the focus will b on the classification of fungi as well as the diseases caused by each group. Here you will get to know about the type of spore, sporangia and fruiting body as well as major diseases and the pathogens of the diseases. At the end there is a glossary of a few terms is added to help clear some of the concepts regarding growth habitat.  KINGDOM FUNGI Fungi are small, generally microscopic, eukaryotic, usually filamentous, branched, spore-bearing organisms that lack chlorophyll.
