Ophiocordyceps unilateralis, commonly known as zombie-ant fungus, is an insect-pathogenic fungus, discovered by the British naturalist Alfred Russel Wallace in 1859. Zombie ants, infected by the Ophiocordyceps unilateralis fungus, are predominantly found in tropical rainforests. These fungi thrive in warm, humid environments, which are ideal for their growth and reproduction. However, they can also be found in warm-temperate forest systems. The fungus primarily targets ants from the tribe Camponotini, including carpenter ants (genus Camponotus). O. unilateralis infects ants of the tribe

Ophiocordyceps is a genus of fungi within the family Ophiocordycipitaceae. The widespread genus, first described scientifically by British mycologist Tom Petch in 1931, contains about 140 species that grow on insects. Anamorphic genera that correspond with Ophiocordyceps species are Hirsutella, Hymenostilbe, Isaria, Paraisaria, and Syngliocladium. One species complex, Ophiocordyceps unilateralis, is known for its parasitism on ants, in which it alters the behavior of the ants in such a way as to propagate itself more effectively, the parasite starts on the ground and comes in contact with an

Hymenostilbe is a genus of fungi in the Ophiocordycipitaceae family. All members are anamorph names of Ophiocordyceps.

Poria hypobrunnea is a plant pathogen infecting tea.

Beauveria brongniartii is an entomopathogenic ascomycete fungus prevalent in various ecosystems, including forest soils, alpine grasslands, and peat bogs. Known for its effectiveness against coleopteran pests, particularly the European cockchafer (Melolontha melolontha) and forest cockchafer (M. hippocastani), B. brongniartii has been widely adopted in biological control strategies across Europe, primarily within agriculture and forestry. Since the early 1990s, commercial formulations like Melocont, Pilzgerste (Agrifutur, Italy) and Beauveria–Schweizer (E. Schweizer Seeds, Switzerland) have

Armillaria fuscipes is a plant pathogen that causes Armillaria root rot on Pinus, coffee plants, tea and various hardwood trees. It is common in South Africa. The mycelium of the fungus is bioluminescent.

Punctularia atropurpurascens, also known as violet crust or purple fuzz, is a species of fungus. Purple fuzz is a saprotrophic crust fungus. The preferred nutrient source of purple fuzz is the wood of deciduous trees. Purple fuzz is prone to guttation and weeps red. Purple fuzz appears to be a fairly widespread fungus capable of adapting to a variety of climates.

Podonectria is a genus in the monotypic Podonectriaceae family of fungi. They are parasitic fungus on scale insects, other fungi, or on substrates that had previously colonized by other fungi. The family of Podonectriaceae was introduced to accommodate genus Podonectria by Dao et al. in 2016. This was later confirmed by ITS and LSU data.
