A drawing on the lower side of the sporocarp of G. applanatum. A peculiarity of this fungus lies in its use as a drawing medium for artists. [14] When the fresh white pore surface is rubbed or scratched with a sharp implement, dark brown tissue under the pores is revealed, resulting in visible lines and shading that become permanent once the fungus is dried.
The genus Pyricularia includes species that are pathogenic on a wide range of monocot plants.For example, Pyricularia oryzae (sexual morph Magnaporthe oryzae), the causal agent of the rice blast disease, is one of the most widely distributed diseases of rice, and is highly destructive leading to up to 30% yield loss worldwide.

The study of reproduction and development in organisms was carried out by many botanists and zoologists.. Wilhelm Hofmeister demonstrated that alternation of generations is a feature that unites plants, and published this result in 1851 (see plant sexuality).
Blastomyces dermatitidis is the causal agent of blastomycosis, a potentially very serious disease that typically begins with a characteristically subtle pneumonia-like infection that may progress, after 1–6 months, to a disseminated phase that causes lesions to form in capillary beds throughout the body, most notably the skin, internal organs, central nervous system and bone marrow.
The mushroom has a broad, fan or oyster-shaped cap spanning 2–30 centimetres (3 ⁄ 4 – 11 + 3 ⁄ 4 inches); [3] natural specimens range from white to gray or tan to dark-brown; the margin is inrolled when young, and is smooth and often somewhat lobed or wavy.
Trametes versicolor – also known as Coriolus versicolor and Polyporus versicolor – is a common polypore mushroom found throughout the world. Meaning 'of several colors', versicolor accurately describes this fungus that displays a unique blend of markings.
Rhizopus oryzae is a filamentous heterothallic microfungus that occurs as a saprotroph in soil, dung, and rotting vegetation. This species is very similar to Rhizopus stolonifer, but it can be distinguished by its smaller sporangia and air-dispersed sporangiospores.
Agroathelia rolfsii occurs in soil as a saprotroph, but can also attack living plants.It has an almost indiscriminate host range, but its capacity to form sclerotia (propagules that remain in the soil) means that it particularly attacks seasonal crops.
