Ophiocordyceps floriformis produces subglobose fertile structures at the terminals, which have a white conidial powder, resembling that of O. buquetii, a species commonly found on ants. The phialides of O. floriformis are Hymenostilbe - like, whereas in O. buquetii, the phialides are cylindrical with papillate ends (Mongkolsamrit et al. 2023). Based on the phylogenetic tree, O. floriformis belongs to the ' O. dipterigena ' complex, while O. buquetii is part of the ' O. australis ' complex. This species is fastidious, and no cultures could be obtained from the collected specimens. Hence, DNA was extracted from the synnemata of natural specimens.</p></div>	https://treatment.plazi.org/id/0968E4C404D958CC94221D1330031702	Public Domain	No known copyright restrictions apply.

These species infect flies of the same family, Asilidae, but differ in their host genus. Ophiocordyceps philippinensis collected in Thailand infects Clephydroneura sp., while O. philippinensis from the Philippines infects Asilus sp. A comparison of morphological features shows that the perithecia and asci of the Thai specimens are larger and longer than those of the Philippine specimens. The part-spores in the Thai specimens are mature, measuring 10–12 × 1.5–2.5 μm, whereas the part-spores in the Philippine specimens are immature (Table 2). Asexual morph reproductive structures, producing Hymenostilbe - like, were observed in the Thai specimen. Observations also revealed that the sexual and asexual morphs occur together on the same specimen, with synnemata emerging from the host’s abdominal region (Fig. 4 A).

This species exhibits unique morphological characteristics. The fly hosts are covered with sparse hyphae that are yellowish-white in colour. The stromata range from yellowish white. The fertile parts are disc-shaped and located at the terminal of the stipe. These characteristics, which resemble those of Hevansia novoguineensis, occur on spiders and can be found on the underside of dicotyledonous leaves in the forest (Mongkolsamrit et al. 2022).</p></div>	https://treatment.plazi.org/id/D64084D684C35268BE3409CF97372DE3	Public Domain	No known copyright restrictions apply.
