Samsoniella coccinellidicola

Ciri dan struktur

Asexual morph: Two synnemata arising from oval cocoons of insect host. Synnemata erect, irregularly branched, starting 2–2.5 mm above the oval cocoons of insect host, 15–25 × 0.8–1.2 mm, pale yellow, isaria-like morph producing a mass of conidia along the synnemata, powdery and floccose. Colonies on PDA fast-growing, 49–52 mm diameter in 14 days at 25 °C, white, cottony, sporulating abundantly, reverse white to pale yellow. Hyphae smooth-walled, branched, septate, hyaline, 0.7–2.1 µm wide. Conidiophores smooth-walled, cylindrical, solitary or verticillate, 4.8–15 × 1.0–1.9 µm. Phialides verticillate, usually in whorls of two to five, or solitary on hyphae, 6.0–14.1 µm long, basal portion cylindrical to narrowly lageniform, tapering gradually or abruptly toward the apex, from 1.0–2.0 µm wide (base) to 0.3–0.8 µm wide (apex). Conidia smooth and hyaline, fusiform or oval, one-celled, 1.8–3.0 × 1.3–2.0 µm, often in chains. Size and shape of phialides and conidia similar in culture and on natural substratum. Notes: The phylogenetic analysis of five genes showed that S. coccinellidicola was closely related to S. pupicola. Morphologically, the new species S. coccinellidicola was distinctly different from S. pupicola due to its longer phialides (6.0–14.1 µm), smaller conidia (1.8–3.0 × 1.3–2.0 µm) and conidia shape. Moreover, S. coccinellidicola was found to occur on an adult beetle (Coleoptera: Coccinellidae), while S. pupicola was found on a Lepidopteran pupa. Based on the previous studies of cordycipitaceous isaria-like fungi as well as our study, there were two species of parasitic Samsoniella in the order Coleoptera, i.e., S. coccinellidicola and S. coleopterorum.
