as a now deleted comment seems to indicate, I can only venture a guess that it resembles Gibellula. Knowing if it’s growing on a spider would provide further certainty. Of the few species of Isaria I’m familiar with, none look anything like this. The host is typically underground, commonly found on cicada nymphs (depending on the sp.), and the stromata consist of light yellow stems terminating in elongated, powdery tufts of white conidia. Images of the few species represented here at MO will confirm this. To what extent any or all of these characteristics are ubiquitous to the genus, I’m not certain, but Gibellula seems a more likely guess based on what information/images are available.

See these photos for comparison:


EDIT: Legs are visible at the front and back of the specimen. Gibellula is a good match. Possibly Gibellula leiopus which has been reported from the east coast.

Can you identify the host?
