NOVELTY - An isolated endophytic Muscodor fungus (I) and an isolated culture (II) of M.albus or M.roseus or mutants of the culture, are new.    USE - (II), (C1) or (C3) is useful for inhibiting the growth of an organism such as fungus, a bacteria, a microorganism, a nematode, or an insect which involves contacting the organism with (II) or (C1). (II), (C1) or (C3) is also useful for treating or protecting fruit, plants, seeds, grain or soil surrounding the plants from an infestation by an organism such as a fungus, a bacteria, a microorganism, a nematode or an insect which involves contacting the organism with (II) or (C1). The method further comprises contacting the fruit, plants, seeds, grain or soil surrounding the plants with an agricultural composition chosen from a fungicide, insecticide, antimicrobial, bactericide, nematocide, and a food preservative. (II) or (C1) is also useful for treating human or animal waste products, and for treating or protecting building material from toxic mold. (II) is useful for obtaining a volatile composition which involves culturing (II) and collecting the composition produced by the growing Muscodor (all claimed). Muscodor gases affect a number of other microbes related to human health issues. It is lethal to the major fungal and bacterial pathogens of humans including Candida albicans and Pseudomonas sp.. It kills bacteria that contaminate food such as Staphylococcus aureus and Escherichia coli. It is also lethal to Stachybotrys sp. (contaminator of homes and public buildings) and a number of wood decay fungi. The fungi and/or its volatile byproduct can be used to treat human or animal waste, e.g., as a component of a waste water or solid management or treatment.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) A volatile composition (C1) produced by (II);    (2) A composition (C2) comprising (II) and a carrier;    (3) A composition (C3) comprising any one of the 28 compounds as given in specification e.g., octane, acetone, ethanol, isobutyl alcohol, etc;    (4) Identifying novel Muscodor fungi comprising contacting the fungi to be screened with the volatiles of M.albus or M.roseus under culturing conditions and selecting the fungi which is resistant to the volatiles of the M.albus or M.roseus thereby identifying novel Muscodor fungi; and    (5) An isolated Muscodor fungus selected by above mentioned method.
