| A thermophilic fungus, identified as Aspergillus cejpii (Aspergillaceae), was isolated from cultures derived from the cap and gill tissues of Agaricus bisporus in Kermanshah, Iran. On potato dextrose agar, colonies exhibited moderate growth, forming white, floccose to lanose mycelial mats. The Vegetative hyphae are hyaline, 2.0–4.7 μm in diameter, frequently forming rhizomorphs. Racquet hyphae, up to 12.5 μm wide, are prevalent (Fig. 2A, B). The fungus produces abundant, discrete, spherical cleistothecia, white to cream in color (Fig. 2C). Cleistothecia originate from tightly wound hyphal coils emerging as lateral branches from vegetative hyphae. At the coil base, hyphae forms loosely branching filaments enveloping the coil, which rapidly develope into pseudoparenchymatous cells. The surrounding interwoven hyphae adhere tightly to the developing cleistothecium. Asci, produced via crozier formation, are globose to subglobose, 9.5–11.5 μm in diameter, eight-spored, evanescent, deliquescing as the ascospores mature. Ascospores are hyaline, lenticular, with two closely appressed equatorial ridges (~0.3 μm wide) and with convex smooth surfaces, 3.2–3.7 × 3.8–4.5 μm. Conidiophores arise as long, smooth-walled, septate branches from aerial hyphae, dichotomously branched once or rarely twice at the apex, typically lacking septa between branchlets and the main axis of the conidiophore. Conidia aleuriospores, formed singly or in chains of two to five, hyaline, thick-walled, smooth, subglobose to pyriform, 6.0–10.0 μm in diameter. | ||
