Saprobic on decaying wood, bark and fruit of various trees and shrubs in terrestrial or freshwater habitats. Sexual morph: Undetermined. Asexual morph: Colonies effuse, grey, brown to black. Mycelium immersed or partly superficial on host substrate. Conidiophores macro- or micronematous, mononematous, often short, straight or irregularly bent, unbranched, pale brown to dark brpwn. Conidiogenous cells mono- or polyblastic, integrated, terminal, sympodial, cylindrical or subulate, denticulate. Conidia solitary, dry, multiseptate, pale brown, often unevenly coloured, the end cells subhyaline, smooth, mostly cylindrical, rounded or tapering at the apex, sometimes rostrate, with or without appendages (Ellis 1971; Hyde et al. 2020b).
Notes: Camposporium is an old genus and characterized by short conidiophores, denticulate conidiogenous cells, and cylindrical, multi-septate, uneven coloured conidia often with single or several cylindrical appendages (Ellis 1971; Hyde et al. 2020b). Camposporium had a relationship with Fusiconidium Jun F. Li et al., but they can be distinguished by conidiogenous cells and conidial shape (Li et al. 2017; Hyde et al. 2020b). They are treated as distinct genera until their relationships are well-resolved (Hyde et al. 2020b). The type species, C. antennatum, represented by a septatum was placed in Camposporium, rather than Fusiconidium, based on its monoblastic conidiogenous cells and cylindrical conidia with several appendages at the apex (Hyde et al. 2020b). Both C. appendiculatum D.F. Bao et al. and C. multiseptatum D.F. Bao et al. have tapering apical cell with truncate ends, while C. antennatum has rounded apex (Ellis 1971; Hyde et al. 2020b). Camposporium hyalinum Abdullah and C. marylandicum Shearer have the typical apical appendages of Camposporium, but they have hyaline conidia which are different from the brown, unevenly coloured conidia of the other freshwater species (Shearer 1974; Abdullah 1980; Hyde et al. 2020b). The molecular data of these two species are needed to confirm their phylogenetic placement. Camposporium species need further study with more collections.
