Type species – Helicocollum surathaniense Luangsa-ard, Mongkols., Noisrip. & Thanakitp.

Notes – This genus is closely related to Aschersonia, Moelleriella, Regiocrella, and Samuelsia, all pathogens of scale insects and whiteflies in Clavicipitaceae (Luangsa-ard et al. 2017a). Helicocollum differs from other scale insect pathogens in having phialides with helical necks and synnematous or sporodochial pycnidial conidiomata. The morphological features of its phialides resemble Hirsutella in the Ophiocordycipitaceae (Luangsa-ard et al. 2017a).
