Pycnidiospores

a spore formed in the pycnidia of certain imperfect fungi; it results in asexual sporogenesis of mycobiontic fungi of lichens. Pycnidiospores vary in shape and coloration and consist of single or multiple cells. They have longitudinal or transverse membranes; appendages may be present or absent. Pycnidiospores form on growths on the basal layer of the pycnidium covering (on the conidium stem). They may result from the disintegration of the contents of pycnidia into separate cells.
