[2] It was later compared to other Brazilian found genera; Cylindrodendrum, Pulvinotrichum and Unicegra which also had similar characteristics but due to the falcate (sickle-shaped) conidia.
[2] The Falcocladium genus was characterized by having thick-walled, non septate (non-walled) stipe extensions that terminate in thin-walled vesicles and appendaged, falcate conidia.
The species fits well within the genus concept of Falcocladium with white sporodochia, bearing thick-walled aseptate, stipe extensions and hyaline, 0–1-septate, a falcate shaped conidia, with short apical and basal appendages.
[1] In 2023, the genus Falcocladium contains 7 known species;[5] The saprobic fungus is distributed mainly in tropical forests,[4][8] and terrestrial habitats including Thailand,[9] Indonesia,[10] and Brazil.
They have a hyaline (glass-like) conidiomata, which is sporodochial or synnematal or penicillate (having tufts of fine hairs), intermixed with setae (bristle or hair-like structures), arising from a stroma or microsclerotia or prostrate mycelium.
[8] Crous et al. (2007a) used the BLASTn tool to compare ITS and LSU gene regions with reference sequences, suggesting the placement of Falcocladium in the Hypocreales order and they further considered the genus to be polyphyletic (organisms with mixed evolutionary origin).
[7] Jones et al. in 2014, then introduced the monotypic family Falcocladiaceae which formed a monophyletic clade in Hypocreomycetidae class, based on analysis of LSU and SSU nuclear genes to accommodate members of Falcocladium.
[15] The Falcocladiales grouped as sister order to Coronophorales and Parasympodiellales with low statistical support (63% maximum likelihood (ML)) in phylogenetic analysis.
[14] In a phylogenetic analysis by Réblová et al. (2016b), Falcocladiales showed close affinity to the orders Coronophorales and Melanosporales.
[2] Falcocladium species can be distinguished based on morphology of vesicular apices of setae which ranges from ellipsoidal, sphaero-pedunculate to turbinate and conidial measurements (Somrithipol et al.
