| sphaerodes mycoparasitica sp. nov., a new biotrophic mycoparasite on fusarium avenaceum, f. graminearum and f. oxysporum. | a new species, sphaerodes mycoparasitica (ascomycetes, melanosporales), was isolated from isolates of fusarium avenaceum and fusarium graminearum originating from wheat fields in saskatchewan, and from fusarium oxysporum originating from asparagus fields in quebec, canada. the species is characterized by a unique combination of ascospore size, shape (fusiform and triangular) and wall ornamentation (reticulate and smooth). also, conidia are produced from simple phialides on the surface of ascoma ... | 2009 | 19857813 |
| biodiversity and biogeography of fusarium species from northeastern north american asparagus fields based on microbiological and molecular approaches. | sixteen fusarium species were recovered from 52 asparagus commercial fields, representing all major ecological (edaphic and climatic) area of asparagus production in the province of québec, eastern canada. this study extends our understanding of the geographic range of these species. it also provides climatological and edaphic properties linked to community changes and adaptations. fusarium oxysporum and f. proliferatum were omnipresent and abundant in all five ecological area under study, where ... | 2006 | 16453201 |
