There are several provisions of the Botanical Code that apply particularly to fungi. For example, lichens, symbiotic associations betwen a fungus and at least one photosynthetic alga or cyanobacterium, are named and classified on the basis of their fungal components. A second provision allowws pleomorphic fungi (those having more than a single morphological form, usually distinguished by spore type) to be named as many times as there are different spore types. For example, the ascomycete Schiffneria pulchra (Sacc.) Petrak has one conidial state known as Sarcinella heterospora Sacc. and yet another conidial state known as Questieriella pulchra S. Hughes (Hughes, 1987). The code allows each distinct state to be named; however the holomorph name, that of the entire fungus in all of its morphological expressions, is the name of the sexual state (S. pulchra).
