''Geosmithia'' is a genus of anamorphic fungi of uncertain familial placement in the order Eurotiales. The genus, circumscribed by Australian mycologist John Pitt in 1979,〔 is widely distributed. A 2008 estimate placed ten species in the genus,〔 but several new species have since been described. Thousand cankers disease, which affects economically important black walnut (''Juglans nigra'') populations in North America, is caused by ''Geosmithia morbida''.〔 Species in the genus are generally similar to those in ''Penicillium'', but can be distinguished from them by forming cylindrical conidia from rough-walled phialides. Additionally, the conidia of ''Geosmithia'' do not have a green color, in contrast to the characteristic blue-grey or green-grey conidia of ''Penicillium''. Some ''Geosmithia'' species have teleomorphic forms that are classified in the genus ''Talaromyces''. The generic name ''Geosmithia'' honors British mycologist George Smith.〔 ==Species== *''Geosmithia eburnea''〔 *''Geosmithia emersonii'' *''Geosmithia eupagioceri''〔 *''Geosmithia fassatiae''〔 *''Geosmithia flava'' *''Geosmithia langdonii''〔 *''Geosmithia lavendula'' *''Geosmithia malachitea''〔 *''Geosmithia microcorthyli'' *''Geosmithia morbida'' *''Geosmithia namyslowskii'' *''Geosmithia obscura''〔 *''Geosmithia putterillii'' *''Geosmithia rufescens''〔 *''Geosmithia swiftii'' *''Geosmithia tibetensis''〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Geosmithia」の詳細全文を読む スポンサード リンク
