Description: Truffle-like fungi with a stipe. Related to the mushrooms, the gills are compressed and distorted inside the enclosed cap.
The secotioid Group is phylogenetically artifical, but a highly
characteristic and easy to recognise part of New Zealand's fungal
biota. Species in this group are biologically diverse. Some are ectomycorrhizal (e.g. the brightly coloured, secotioid Cortinarius species), while others are saprobic (e.g. Weraroa).
The secotioid Cortinarius species were previously treated as Thaxterogaster, and are listed under that name in many New Zealand publications and field guides.
