A longitudinal section of a wax embedded excision from an asexually sporulating culture of S. nodorum SN15 -stained with toluidine blue. Pictured are pycnidiospores being released from a mature pycnidium. Arrows point to the masses of enlarged cells producing the ostiole, formed in the development of the mature pycnidium, from which the pycnidiospores are released from the pycnidial cavity as a cirrus. Cv, pycnidial cavity; W, pycnidial wall; Ch, cirrus.
