Fusarium circinatum is a fungal plant pathogen that causes the serious disease pitch canker on pine trees and Douglas firs (Pseudotsuga menziesii). The most common hosts of the pathogen include slash pine (Pinus elliottii), loblolly pine (Pinus taeda), Monterey pine (Pinus radiata), Mexican weeping pine (Pinus patula), and Douglas fir. Like other Fusarium species in the phylum Ascomycota, it is the asexual reproductive state of the fungus and has a teleomorph, Gibberella circinata.

Morchella importuna is a species of fungus in the family Morchellaceae described from North America in 2012. It occurs in gardens, woodchip beds, and other urban settings of northern California and the Pacific Northwest region of the United States and Canada. The fungus has also been reported from Turkey, Spain, France, Switzerland, Canada and China, although it is unknown whether this is a result of accidental introductions. It is considered a choice edible mushroom. The fruit bodies develop a distinctive ladder-like pattern of pits and ridges on the surface of their conical caps.

Crown rot of wheat is caused by the fungal pathogen Fusarium pseudograminearum. F. pseudograminearum is a member of the fungal phylum Ascomycota and is also known as Gibberella coronicola (teleomorph). It is a monoecious fungus, meaning it does not require another host other than wheat to complete its life cycle. Although F. pseudograminearum can produce both anamorphic and teleomorphic states, the teleomorph is usually not present for crown rot of wheat. This Fusarium species has, until recently, been considered to be the same as the species known as Fusarium graminearum (head blight of

Fusarium pseudoanthophilum is a species of fungus in the family Nectriaceae. It was first described by Kerry O'Donnell and Jürgen Kroschel in 1998 as Fusarium brevicatenulatum. It was then listed as a synonym of F. brevicatenulatum by Amata and colleagues in 2010, who confirmed the species are the same through sexual compatibility tests. As of April 2024, Index Fungorum does not recognize the proposed synonymy. The original 1998 publication included both F. brevicatenulatum and F. pseudoanthophilum. No information was found to locate a type specimen of the species. Research papers noted that

Fusarium acutatum is a fungus species of the genus Fusarium. Fusarium acutatum can cause gangrenous necrosis on the feet from diabetic patients. Fusarium acutatum produces fumonisin B1, fumonisin B2, fumonisin B3 and 8-O-Methyl-fusarubin.

Fusarium acaciae-mearnsii is a fungus species of the genus Fusarium which produces zearalenone and zearalenol.

Morchella australiana is a species of ascomycete fungus in the family Morchellaceae. Described as new to science in 2014, it is found in New South Wales, South Australia, Tasmania and Victoria, Australia. The type locality was in the temperate Pilliga Scrub of northwestern New South Wales, west of the Great Dividing Range. Fruit bodies of the fungus resemble those of the European Morchella elata, but molecular and morphological analyses demonstrated that the Australian species represents a unique lineage.

Morchella sceptriformis is a species of fungus in the family Morchellaceae (Ascomycota). It was described as new to science in a 2012 study by Clowez, and corresponds to phylogenetic lineage Mes-3. Morchella virginiana, described later in the same year by Kuo and colleagues, is a junior synonym. This putatively endemic North American morel is so far known from North Carolina, South Carolina, Mississippi and Virginia, where it is found under the American tulip tree (Liriodendron tulipifera).
