Cryptomycota ('hidden fungi'), Rozellida, or Rozellomycota are a clade of micro-organisms that are either fungi or a sister group to fungi. They differ from classical fungi in that they lack chitinous cell walls at any trophic stage in their lifecycle, as reported by Jones and colleagues in 2011. Despite their unconventional phagocytic feeding habits (typical fungi are osmotrophic), chitin has been observed in the inner layer of resting spores, and in immature resting spores for some species of Rozella, as indicated with calcofluor-white stain as well as the presence of a fungal-specific chitin synthase gene.
