It has proven difficult to confirm the oft-repeated assumption that Paecilomyces is a Cordyceps anamorph (Samson et al., 1988), due to lack of cultural proof. As pointed out by Samson and Evans (1977), There is no indication that P. tenuipes represents the imperfect state of some Cordyceps species, as suggested by Petch (1933) and Kobayasi (1941). However, evidence has now been obtained from a molecular phylogenetic analysis carried out by Fukatsu, et al., (1997), which showed that Paecilomyces tenuipes (Peck) Samson belongs to the monophyletic group of the Clavicipitales. Ascospore isolations from several undescribed Cordyceps spp. from Amazonia have also yielded Paecilomyces type anamorphs in culture (H. C. Evans, unpublished data). (Figs. 9 and 10). 

Several species of Paecilomyces, including P. farinosus, P. fumosoroseus, P. tenuipes, and P. lilacinus, have been developed as biocontrol agents of insects and other invertebrates. Paecilomyces lilacinus, a nematode pathogen (Esser and El-Gholl, 1993 Bissett, 1979), may cause opportunistic infection in humans (Blackwell et al., 2000 Itin et al., 1998).
