The Heterogastridiales are an order of fungi in the class Microbotryomycetes. The order contains a single family, the Heterogastridiaceae,[2] which currently contains five genera.[3] Some species in the order are currently known only from their yeast states.[4] Those producing hyphal states have auricularioid (laterally septate) basidia and are parasitic on other fungi. Basidiocarps (fruit bodies), when present, are minute and variously stilboid (pin-shaped),[5] pustular,[6] or pycnidioid (flask-shaped).[2] Molecular research, based on cladistic analysis of DNA sequences, has shown that the order is a monophyletic (natural) group, though the type and only species of Krieglsteinera[1] has not yet been sequenced and may belong elsewhere.[3]
