Athelia rolfsii
''Athelia rolfsii'' is a corticioid fungus in the family Atheliaceae. It is a facultative plant pathogen and is the causal agent of "southern blight" disease in crops.
==Taxonomy==
The species was first described in 1911 by Italian mycologist Pier Andrea Saccardo, based on specimens sent to him by Peter Henry Rolfs who considered the unnamed fungus to be the cause of tomato blight in Florida. The specimens sent to Saccardo were sterile, consisting of hyphae and sclerotia. He placed the species in the old form genus ''Sclerotium'', naming it ''Sclerotium rolfsii''. It is, however, not a species of ''Sclerotium'' in the strict sense.
In 1932, Mario Curzi discovered that the teleomorph (spore-bearing state) was a corticioid fungus and accordingly placed the species in the form genus ''Corticium''. With a move to a more natural classification of fungi, ''Corticium rolfsii'' was transferred to ''Athelia'' in 1978.
