    Notes: [Auszug] Nuclei of fungal hyphae being extremely small, Unna staining will be of additional help in distinguishing the haploid from the diploid states by the respective sizes of the nuclei. DNA in the nuclei is rather of a transitory nature, hence all the nuclei in a mycelium do not take the same prominent ...
