Arachnomyces bostrychodes is a species of infectious ascomycete fungus discovered in 2021 from clinical specimens of fungal strains in Texas, United States.
The specific epithet comes from the Greek òÿÃÂÃÂÃÂàÃÂÿÃÂ-, meaning curl, referencing the curly appearance of the reproductive hyphae.
Arachnomyces bostrychodes grows septate, hyaline, branched, vegetative hyphae with smooth and thin walls, between 1 and 2âÂÂüm wide. The fertile hyphae are well-differentiated, arising as lateral branches from the vegetative hyphae, successively branching to form dense, tightly curled, sinuous clusters that are also between 1 and 2 üm wide, forming random arthroconidia both intercalary and terminally.
The conidia measure 4âÂÂ8 x 1âÂÂ2 üm, are mostly curved and truncated at one or more commonly both ends; they are enteroarthric, hyaline, one-celled, smooth-walled, cylindrical, barrel-shaped; they are finger-shaped when terminal. The conidia are separated from the fertile hyphae by . There have been no observations of chlamydospores, racquet-shaped hyphae, setae, or sexual reproduction.
