suggests synonymy between the sphingums, tuberculatas and pistillariaeformis…es, all of which have been described at one time or another in either Cordyceps, Isaria, Hymenostilbe, Akanthomyces, or some combination of the four. That covers all the strongly synnematous, adult moth-loving entomopathogens I can think of off the top of my head… can there really be only one sp. in the whole of NA?

why H. sphingum and not Akanthomyces/Cordyceps tuberculata?

In 1931 Petch (10) proposed the form-genus Hymenostilbe for H. muscarium, a species on flies, as well as for Isaria arachnophila Ditm. and for the conidial stages of several species of Cordyceps, namely C. dipterigena, C. lloydii and C. australis. Later (13) when he discussed Akanthomyces aculeata, he expressed doubt whether Hymenostilbe could be maintained as distinct from Akanthomyces. However, he (15) flnally concluded that they are distinct, the most important difference being that the conidia of Akanthomyces are catenulate and those of Hymenostilbe solitary on the phialide. This is a distinction which is commonly used in the separation of genera in the Fungi Imperfecti.

(emphasis mine)

Mains, E.B. “Entomogenous Species of Akanthomyces, Hymenostilbe and Insecticola in North America.” Mycologia 42.4 (1950): 566-589.

update: there appears to be a great deal of synonymy among these anamorphic genera:

Hymenostilbe sphingum = Akanthomyces sphingum = Isaria sphingum

all of which the One Fungus, One Name rule dictates be called Cordyceps sphingum anyway. Still, there are other Lepidoptera-infecting species to consider, particularly in the absence of microscopy.

that’s gotta hurt.
