In medically important fungi, an uncharacterized A78 virus of A. fumigatus causes mild hypervirulent effect on pathogenicity when tested on Galleria mellonella (Greater wax moth). [42] Furthermore, TmPV1, a dsRNA partitivirus, of Talaromyces marneffei (formerly Penicillium marneffei) was found to cause hypervirulence phenotype on T. marneffei ...
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.
In certain areas of the temperate northern hemisphere where fungi have been well studied, the ratio of vascular plant to fungal species is about 6 to 1. [2] This suggests that there may be as many as 120,000 species of fungi within the United States, surpassing the 29,000 U.S. species of microfungi estimated based on collection and literature ...
The English word fungus is directly adopted from the Latin fungus (mushroom), used in the writings of Horace and Pliny. [10] This in turn is derived from the Greek word sphongos (σφόγγος 'sponge'), which refers to the macroscopic structures and morphology of mushrooms and molds; [11] the root is also used in other languages, such as the German Schwamm ('sponge') and Schimmel ('mold').
[13] [14] Different mycoparasitic fungi form different structures when interacting with their hosts. For example, the hyphae of some mycoparasitic fungi form specialized contact cells resembling haustoria on the hyphae of their hosts; others may coil around the hyphae of their host fungus or penetrate then grow inside host hyphae.

The evolution within the Clavicipitaceae is marked by interkingdom host jumping, and the range of this large and heterogeneous fungal group spans mutualistic plant symbionts, as well as parasites of plants, insects, and other fungi.
Rust fungi grow intracellularly, and make spore-producing fruiting bodies within or, more often, on the surfaces of affected plant parts. [3] Some rust species form perennial systemic infections that may cause plant deformities such as growth retardation, witch's broom , stem canker, galls , or hypertrophy of affected plant parts.
The Agaricales are an order of fungi in the division Basidiomycota.As originally conceived, the order contained all the agarics (gilled mushrooms), but subsequent research has shown that not all agarics are closely related and some belong in other orders, such as the Russulales and Boletales.
