C. kirkii appears similar to a collection in the herbarium of the Commonwealth Mycological Institute (I.M.I. 27419) from Trinidad named by Mr. E.W.Mason as C. joaquensis P.Henn. The latter parasitises Gryllotalpus sp. an allied genus to Deinacrida. No type material was available for examination: C. kirkii is retained as a separate species.
