Blasiphalia is a fungal genus in the family Repetobasidiaceae.
[1] Phylogenetically related agarics are in the genera Rickenella, Gyroflexus, Loreleia, Cantharellopsis and Contumyces, as well as the stipitate-stereoid genera Muscinupta and Cotylidia and clavarioid genus, Alloclavaria.
[2] Blasiphalia is most similar to Rickenella and Contumyces, and was only just recognized as a distinct genus in 2007 based upon molecular analysis.
The fungus is unique in parasitizing Blasia[2] by forming clasping appresoria on its host's rhizoids.
Blasiphalia is a nonsense, nontraditionally formulated name vaguely referring to the liverwort genus Blasia and a fragment of the word 'omphalia' in reference to previous classifications that would place it in Omphalina.
