Hi Sherri,
If all of your hostas have came from the same plant, and this is the only one that has issues...I would probably dispose of it. Do not compost it, and sterilize your tools afterward with a 10-20% solution of bleach and water. Looks like it could be hosta virus x with the bleed through showing.
@ViolaAnn,
@Rose1656 and
@Hostamore may want to weigh in.
