These medicinal plants have been arranged alphabetcally, along with the fungi they host. This (Kirk et al. 2001), while sporadic work has been done in work has resulted in recording 253 fungal taxa, belonging to 44 genera India (Kushwaha 2004). of Ascomycetes, Basidiomycetes and Fungi Imperfect. Keywords: Herbal drugs, leaf diseases, pathogenic fungi. Materials and Methods The foliicolous fungi mainly infect leaves, sof stems and tender shoots. Collecton of these fungi is much easier India harbours more than 18,000 fowering plants of than that of feshy fungi. While collectng the host plant which about 7,500 are being used by all the ethnic groups parts, feld notes were made regarding their pathogenic and ca. 400 are industrially viable in producing about efect on the host, nature of colonies, nature of infecton, 10,000 herbal drugs (Shankar et al. 1997; Dhar 2002). locality and alttude. For each collecton, a separate feld It has been notced and confrmed that the pathogenic number was given. In the feld, such infected plants were fungi play a vital role in bringing chemical changes among collected separately in polythene bags with the host plants in increasing the efcacy of medicinal plants; for twig, preferably with the reproductve parts to facilitate example, Phyllanthus amarus Schum. & Thonn. is efectve the corresponding host identty.
