Geosmithia is a genus of anamorphic fungi of uncertain familial placement in the order Hypocreales. The genus, circumscribed by Australian mycologist John Pitt in 1979,[1] is widely distributed. A 2008 estimate placed ten species in the genus,[2] 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.[3]
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. However, Geosmithia is a polyphyletic taxon with evolutionary affinities to at least three groups of the euascomycete lineage within the Ascomycota.[4] The generic name Geosmithia honors British mycologist George Smith.[1]
