Ciri dan struktur
Asexual morph: Mycosed hosts covered by dense white to lavender mycelia, produces numerous white, powdery conidia. Colonies on PDA fast-growing, 47–50 mm in diameter after 14 days at 25 °C, villiform, light yellow in the middle with a white edge, middle hyphae thickening, reverse light yellow. Hypha smooth-walled, hyaline, septate, 0.7–1.8 µm wide. Conidiophores smooth-walled, cylindrical, solitary or verticillate, 2.4–14.0 × 0.9–1.8 µm. Phialides verticillate, usually in whorls of two to four or solitary on hyphae, 3.0–13.5 µm long, basal portion cylindrical to narrowly lageniform, tapering gradually or abruptly toward the apex, from 0.6–1.6 µm wide (base). Conidia smooth and hyaline, oblong to cylindrical, one-celled, 1.6–2.8 × 0.6–1.2 µm, often in chains. Size and shape of phialides and conidia similar in culture and on natural substratum. Notes: Morphologically, S. farinospora resembled the phylogenetically sister species S. hepiali. They had the same host, the Hepialid larva, and isaria-like asexual conidiogenous structures, producing synnemata with powdery conidia at the apex. However, S. farinospora was also found to occur on a spider. Parasitic Samsoniella species on spiders had rarely been reported. In addition, our morphological observation revealed a significant difference in conidia sizes between S. farinospora (1.6–2.8 × 0.6–1.2 µm) and S. hepiali (1.8–3.3 × 1.4–2.2 µm). Both the morphological study and phylogenetic analyses of combined nr SSU, nr LSU, tef-1α, rpb1 and rpb2 sequence data supported the idea that this fungus was a distinctive species in the genus of Samsoniella.
