Fusarium has a lot of variations. The one I have identified is Fusarium Solani. The one talked about below as the "pot eating fungus" is Fusarium Oxysporum and I don't know how different they are. The topic of Fusarium hasn't really been in the news for a while so most of the info is old. Fusarium ‘solani’ p 51 17 Sanger ACJF 17 aThe pea pathogen Fusarium ‘solani’ belongs to an undescribed species in the F. solani species complex. It is often referred to as Nectria haematococca mating population VI (17).
Members of the Fusarium solani species complex (FSSC) are the most frequently isolated fusaria from soil. Moreover, this complex solely affects more than plant genera, and is also one of the major opportunistic human pathogenic filamentous fungi, being responsible for approximately two-third of fusariosis cases. Mycotic keratitis due to Fusarium species is among the leading causes . Fusarium fungi are soil-borne pathogens, and the pathological effects on plant photosystems remain unclear. This study aimed to deeply reveal pathological characterization in apple seedlings infected with Fusarium solani by investigating photosystems performance and interaction. Roots were immersed in conidial suspension for inoculation. Thereafter, prompt and delayed chlorophyll a.
Six different species were identified. Fusarium solani was the most frequently isolated, followed by Fusarium oxysporum, Fusarium proliferatum and Fusarium ericin B was the only drug with in vitro activity (range: –32 mg/L). The rest of the antifungals tested (itraconazole, voriconazole, ravuconazole, posaconazole and terbinafine) showed very poor activity against. Members of the Fusarium solani species complex (FSSC) are increasingly implicated as the causative agents of human mycoses, particularly in the expanding immunocompromised and immunosuppressed patient populations. Best known as ubiquitous plant pathogens and saprotrophs, the FSSC comprises over 45 phylogenetically distinct species distributed among three major clades.

Extension Center, Prosser, Wash.) for F. solani clones NP-W. Accepted for publication 13 December ABSTRACT The pisatin-inducing potential and the relative pisatin sensitivity of two pathogenic and two nonpathogenic clones of Fusarium solani were compared to evaluate the role of pisatin as a resistance component in the foot.
The large number of the investigated natural strains of N. haematococca was found to contain the strains both highly pathogenic and nonpathogenic for peas, the degree of pathogenicity correlating with the ability to demethylate pisatin.
In crossing of the pathogenic with nonpathogenic strains, the hybrid monoascosporous isolates were. Fusarium solani is a species complex of at least 26 closely related filamentous fungi in the division Ascomycota, family Nectriaceae.
It is the anamorph of Nectria haematococca. It is a common soil fungus and colonist of plant materials. Fusarium solani is implicated in plant disease as well as human disease notably infection of the cornea of the : Sordariomycetes.
The sequence analyses of clone F1 revealed a high level of identity with F. solani, which can be considered a plant pathogen (9,13,28), while nonpathogenic strains do exist as common soil. Induction of pisatin in the pea foot region by pathogenic and nonpathogenic clones ofFusarium solani.

Fusarium solani is one of the most frequently isolated fungi from soil and plant debris and is also associated with serious invasive mycoses in immunocompromised and immunosuppressed patients (3, 18).This species, as defined based on morphology, is actually a diverse complex of over 45 phylogenetic and/or biological species (13 and this study), termed the Fusarium solani species complex (FSSC).

The antiserum was used to study the first 8 hours of the phenylalanine ammonia-lyase activity response in two different organs of the pea from different developmental stages and in response to two different stimuli. Etiolated seedlings were pulse-labeled with l-[35S.
Both pathogenic and nonpathogenic strains were assigned to the independent VCGs. This suggested that the isolates of F. solani pathogenic to tobacco were derived from the progenies of crossing in the field. However, perithecium formation was not observed in their cultures.

Two nonpathogenic strains of Fusarium oxysporum (C5 and C14) introduced into soil at X 10(4) and 5 X 10(4) colony-forming units (cfu) per gram of soil significantly decreased the slope values. The pathogenicity of seven strains of Fusarium equiseti isolated from seabed soil was evaluated on different host plants showing pre and post emergence damage.
Radial growth of 27 strains was measured on culture media previously adjusted to different osmotic potentials with either KCl or NaCl ( to bars) at 15°, 25° and 35° C.

Fusarium solani (Mart.) Sacc.(teleomorph = Nectria haematococca (Berk. & Br.) is a phytopathogenic fungus and is an important causal agent of several crop diseases, such as root and fruit rot of Cucurbita spp., root and stem rot of pea, sudden.

in American Ginseng Roots Seven days after inoculation with F. solani (strain F19), cream sparse mycelia were present on the root surface, originating from the inoculation point.
The Fusarium solani species complex (FSSC) is a group currently estimated to contain at least 60 phylogenetically distinct species (Nalim et al., ; O'Donnell, ; O'Donnell et al., ; Zhang et al., ).
As defined by Snyder and Hansen, F. solani was the only species. Fusarium solani. Fusarium solani isolated from the bark of a yew tree from the eastern Himalayas showed antimicrobial activity against three Gram-positive bacteria (S.
aureus, B. subtilis, and Staphylococcus epidermidis), three Gram-negative bacteria (K. pneumoniae, E. coli, and Shigella flexneri) and two pathogenic fungi (Candida albicans and Candida tropicalis) .
In peas, the disease is caused by a number of fungi, but most notably by Nectria haematococca (anamorph Fusarium solani f. sp. pisi) (Funnell et al. ). Nectria haematococca is pathogenic on all commercial processing pea cultivars (Hagedorn ; Grünwald et al.
) and is responsible for yield losses of between 35% and 57% (Kraft.Suga et al. () has investigated phylogenetic relationships of Fusarium solani using sequences from the rDNA-ITS region.
