Alleluia Haec est vera*

This incipit is too short. It could correspond either to g00189 or g02805. There is a reference in Roman numbers to fol. 87, however, this chant isn't there. Furthermore, there is an incipit of the same chant on fol. 27v, which adresses to fol. 88. However, this folio is also missing from the manuscript.
