During a survey of perithecial ascomycetes in New Zealand, two collections of a Togninia-like fungus were made on decayed wood. In culture, colonies produced a Phaeoacremonium-like anamorph. Nuclear LSU and SSU ribosomal DNA sequences of these fungi and other related fungi, morphological and cultural characteristics, confirm that the New Zealand fungus represents a new genus very close to Calosphaeria. The new genus Togniniella is proposed, while Phaeocrella is established for its anamorphs. Furthermore, Calosphaeria pulchella was found to form a distinct Acremonium-like anamorph in culture, for which the genus Calosphaeriophora is proposed. Two families are described; the Pleurostomataceae for Pleurostoma with Pleurostomophora anamorphs, the Togniniaceae for Togninia with Phaeoacremonium anamorphs.

Během výzkumu peritheciálních askomycetů na Novém Zélandu byly na tlejícím dřevě nalezeny dva sběry houby připomínající r. Togninia. V kultuře houba produkovala kolonie typu Phaeoacremonium. Sekvence 28S a 18S rDNA, morfologické znaky a kultivační charakteristiky potvrdily, že tato houba reprezentuje nový rod blízce příbuzný r. Calosphaeria. Tento nový rod Togniniella je zde popsán a Phaeocrella je popsána jako nový rod pro jeho anamorfy. Anamorfa, kterou vytvořila Calosphaeria pulchella v kultuře je nově popsána jako Calosphaeriophora. Jsou rovněž popsány dvě nové čeledi: Pleurostomataceae pro Pleurostoma s Pleurostomophora anamorfou a Togniniaceae pro Togninia s Phaeoacremonium anamorfou.
