 More hyphae then grow into the palisade tissue and continue on into other air chambers, eventually emerging through stomata in the streak that has developed.Further epiphytic growth occurs before the re-entry of the hypha into the leaf through another stoma repeats the process.Both conidia and ascospores are important for dispersal of M. musicola with the ascospores being involved in the movement of the pathogen over longer distances than the conidia.
