Paecilomyces tenuipes (Peck) Samson, Stud. Mycol. 6: 49. 1974.

 Description: Infected lepidopteran pupae covered by dense, adpressed weft of mycelium, white to yellowish white, pale yellow, light yellow (4A2-4), bearing numerous distinct synnemata. Hyphae hyaline, septate, smooth-walled, branched, 1.2-4.0 μm wide. Synnemata cylindrical, erect or prostrate, simple, or dichotomously or irregularly branched, yellow (2A6-7), becoming greyish orange (5B3-5) in age, 1.8-19.6 mm long, 0.5-4.3 mm wide, with a sterile stipe, and fertile apex, powdery, filamentous, white to yellowish white (4A2), consisting of compact, longitudinal parallel, septate hyphae. Conidiophores mono- or synnematous, septate, smooth-walled, hyaline, 2.0-3.5 μm wide, bearing groups of metulae, forming terminally or beneath septa, broadly clavate or cylindrical, 4.4-10.5 × 3.5-5.0 μm, often further branching, giving rise to swollen lateral cells or whorls of 2-7 phialides in the first or second order, sometimes phialides arising directly from conidiophores or hyphae. Phialides smooth-walled, 3.6-6.4(-7.1) × 2.4-3.4 μm, cylindrical or flask-shaped, with a globose swollen base, tapering into a distinctly thin neck, up to 4.4 μm long, 0.8-1.6 μm wide. Conidia mostly allantoid, sometimes ovoid to broadly ellipsoidal, one-celled, hyaline, 2.9-5.9 × 1.4-2.9 μm. Chlamydospores absent.
