Curvularia
''Curvularia'' is a hyphomycete (mold) fungus which is a facultative pathogen of many plant species and of the soil. Most ''Curvularia'' are found in tropical regions, though a few are found in temperate zones.
''Curvularia'' defined by the type species ''C. lunata'' (Wakker) Boedijn. ''Curvularia lunata'' appears as shiny velvety-black, fluffy growth on the colony surface. ''C. lunata'' is distinguished by septate, dematiaceous hyphae producing brown, geniculate conidiophores. The poroconidia are curved slightly to distinctly, transversely septate, with an expanded third cell from the pore end of the conidium. ''Curvularia'' can be easily distinguished from ''Bipolaris'' and ''Drechslera'' spp. since the conidia are non-distoseptate, that is, septate from edge to edge of the conidial wall. The teleomorphic state of the type species ''Curvularia lunata'' is ''Cochliobolus lunatus'' (Fam. Pleosporaceae, Ord. Pleosporales, Cla. Loculoascomycetes, Phy. Ascomycota).
==Heat-tolerance symbiote==
''Curvularia protuberata'' is an endosymbiote of panic grass (''Dichanthelium lanuginosum'') that enables it to thrive near hot springs in soil temperatures of up to 104° F (40° C). The fungus confers this protective effect only when itself infected by the Curvularia thermal tolerance virus (CThTV). Plants unrelated to panic grass also experience this protective effect when inoculated with the virus-infected fungus.〔(reference to Redman, Rodriguez, and Henson experiment )〕
