A diagram showing the infecting structures and effector delivery strategies of a model hemibiotrophic pathogen, Phytophthora infestans. Fungal effectors are proteins or non-proteinaceous molecules (such as RNAs or small molecules) secreted by pathogenic fungi into a host organism in order to modulate the host's immune response.
Pathogenic fungi are fungi that cause disease in humans or other organisms. Although fungi are eukaryotic , many pathogenic fungi are microorganisms . [ 1 ] Approximately 300 fungi are known to be pathogenic to humans; [ 2 ] their study is called " medical mycology ".
Viewing the fungi under a microscope, Micheli was reminded of the shape of an aspergillum (holy water sprinkler), from Latin spargere (to sprinkle), and named the genus accordingly. [ 2 ] [ 3 ] Aspergillum is an asexual spore-forming structure common to all Aspergillus species; around one-third of species are also known to have a sexual stage ...
Fusarium oxysporum f.sp. cubense is a fungal plant pathogen that causes Panama disease of banana (Musa spp.), also known as fusarium wilt of banana. Panama disease affects a wide range of banana cultivars, which are propagated asexually from offshoots and therefore have very little genetic diversity.

Carex utriculata with smut fungus affecting individual seeds. The smuts are multicellular fungi characterized by their large numbers of teliospores.The smuts get their name from a Germanic word for 'dirt' because of their dark, thick-walled, and dust-like teliospores.
The pathogen M. phaseolina affects the fibrovascular system of the roots and basal internodes of its host, impeding the transport of water and nutrients to the upper parts of the plant. [7] As a result, progressive wilting, premature dying, loss of vigor, and reduced yield are characteristic symptoms of M. phaseolina infection. [8]
Similar haustoria are found in biotrophic plant, animal and fungal pathogens in several other major fungal lineages. Like most other zygomycete fungi, the Zoopagomycotina have cell walls containing chitin and have coenocytic (nonseptate) hyphae. Their vegetative body consists of a simple, branched or unbranched thallus.
