The tectofilosids are a group of filose
euglyphids, which produce shells from siliceous scales. The shell usually has a single opening, but in Amphitrema and a few other genera it has two on opposite ends. The cell itself occupies most of the shell. They are most often found on marsh plants such as Sphagnum
.
This group was previously classified as the Gromiida or Gromiina. However, molecular studies separate monophyly are not yet certain.
In a recent classification, the group Tectofilosida was not used: Chlamydophryidae, Psammonobiotidae,
Pseudodifflugiidae and Volutellidae were dispersally placed in Thecofilosea, while Amphitremidae was included in Labyrinthulomycetes.[2]
