Abstract: The present invention provides a method of detecting a functional filamentous fungus, wherein the functional filamentous fungus, Coprinellus curtus, in a sample is detected using at least one polynucleotide selected from the group consisting of polynucleotides having a nucleotide sequence shown in SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3 or SEQ ID NO: 4 and polynucleotides having a nucleotide sequence complementary thereto, and polynucleotides having a nucleotide sequence substantially homologous to these sequences; and a method of evaluating a product containing a functional filamentous fungus wherein the existence or concentration of the functional filamentous fungus, Coprinellus curtus, in a product containing a functional filamentous fungus is evaluated.

Abstract: The method for producing functional compost according to the invention includes: inoculating a filamentous fungus with a function, such as the Coprinus curtus GM-21 strain (NITE BP-37) with a plant disease control function, into compost in an bacterial-activity-restricted state which is, for example, at least one state selected from the group consisting of a nutrient-restricted state, a pH-restricted state and a water content-restricted state; and cultivating the filamentous fungus in the compost to allow its selective proliferation. Further, the invention provides functional compost obtained by the above production method, as well as compost for proliferating a filamentous fungus in a bacterial-activity-restricted state.

Abstract: The present invention provides a plant disease control agent which is stable and safe in terms of leaving no residue and a method for controlling plant diseases using the same. The plant disease control agent comprises a fragment of an inky cap mushroom, and plant diseases are controlled by using the plant disease control agent. The plant disease control agent may be a suspension comprising the fragment of the inky cap mushroom or a solid material composed of the suspension and a carrier to which the suspension is absorbed. The inky cap mushroom is preferably Coprinus curtus or the like, especially preferably Coprinus curtus GM-21 (NITE BP-37).
