Arachnomyces bostrychodes is a species of infectious ascomycete fungus discovered in 2021 from clinical specimens of fungal strains in Texas, United States.

[1][2] The specific epithet comes from the Greek βοστρυχος-, meaning curl, referencing the curly appearance of the reproductive hyphae.

[1] A. bostrychodes grows septate, hyaline, branched, vegetative hyphae with smooth and thin walls, between 1 and 2 μm 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 μm wide, forming random arthroconidia both intercalary and terminally.

[1] The conidia measure 4–8 x 1–2 μm, 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.
