The taxonomic status of the genera Micrhystridium, Baltisphaeridium, Vevyhachium, Multiplicisphaeridium, Leiosphaeridia, Leiosphaeridium, Protoleiosphaeridium, and Archaeohystrichosphaeridium is examined. The generic names Multiplicisphaeridium, Leiosphaeridium, and Protoleiosphaeridium are rejected: the genera Micrhystridium, Baltisphaeridium, Leiosphaeridia, and Veryhachium are redefined: and lists are given of the species now considered to belong to these genera, the generic attribution of 140 species being changed.
