Book excerpt: This book is written remembering of medical technologist working in pathology lab with least knowledge of fungi compare to other branches of medical sciences. This book, although, equally good for clinicians and veterinary doctors to know about the fungi of clinical importance and hence, could go for an appropriate treatment. Morphological description with photograph is given for 114 species of fungi to identify the clinical fungi easily and accurately. These fungal belong to following Genera of fungi: Absidia, Acremonium, Acrophialophora, Actinomyces, Actinomadura, Actinomucor Alternaria, Aphanoascus, Arthroderma, Aspergillus, Aureobasidium, Basidiobolus, Beauveria, Bipolaris, Blastomyces, Botrytis, Chaetomium, Chrysosporium, Cladophialophora, Clavispora, Coccidioides, Colletotrichum, Conidiobolous (Entomophthora), Cryptococcus, Cunninghamella, Curvularia, Cyberlindnera, Debaromyces, Diutina, Epidermophyton. Emmonsia, Exophiala, Exserohilum, Fonsecaea, Fusarium, Geotrichum, Histoplasma, Kluveromyces, Laphophyton, Lasiodiplodia, Madurella, Malassezia, Microsphaeropsis, Microsporum, Mortierella, Mucor, Ochroconis, Nocardia, Paecilomyces, Paraphyton, Penicillium, Phoma, Prototheca, Pseudallescheria, Pythium, Rhinocladiella, Rhinosporidium, Rhizomucor, Rhizopus, Rhodotorula, Saccharomyces, Scedosporium, Schyzophyllum, Scopulariopsis, Scytalidium, Sporothrix, Stachybotrys, Stemphylium, Streptomyces, Syncephalastrum, Trichoderma, Trichophyton, Trichosporon, Ulocladium, Veronaea, Verruconis, Verticillium and Wangiella Besides this, a medical mycology lab manual is also given for handling clinical fungi starting from collection to proper isolation and correct identification. Methodology of manual is illustrated to be easily followed by the technicians. A new technique for the isolation of fungi from clinical samples is described here that reduce the possibility of air borne lab contaminations. The lab contaminations are a big problem for determination of fungal pathogens, but this technique almost eliminate the possibility of lab contaminations.Scientific terms used for fungal descriptions are explained in Mycological Terminology section. Questions usually asked about the fungi are given in Frequently Asked Questions section. A sheet is provided to follow step-by-step identification of fungus in "Steps in fungal Identification (Sheet)". How to identify common Candida species by seeing color of Candida species on Chromagar and microscopic morphology is given for rapid identification in "Definitive Identification of Common Pathogenic Candida species on Chromagar and Sabouraud Dextrose Agar (SDA)".
