Ascomycete paraphyses are often long enough to resemble actual hairs. Cells of this nature that occur, not actually among the asci, but towards the edge of the hymenium, at the mouth (ostiole) of a perithecium containing the hymenium, are not called paraphyses, but periphyses. Also, sometimes long hair-like cells grow down from the roof of locules (but not perithecia), and often end up connecting the roof and the floor of the locule. These cells are called pseudoparaphyses, and they are the other reason that calling Basidiomycete hymenial cells paraphyses is a bad idea.
