The living hyphse are applied to the host so closely thatunstained they are invisible, the perithecia appearingunattached. Saffranine, eosine and iodine are ineffectivebut cotton-blue stains the protoplasm intensely by whichmeans the hyphse can be traced. They have a habit whichdistinguishes them at once from those of moulds and strayspores which sprout in profusion in the felt of lie in the grooves between the outer convex walls ofthe cells of the liverwort, in most cases singly, and at thecorners of the host-cells, over the junctions of theiranticlinal walls, each hyphal cell bears a 3.
