Hylocomium buds

    Hi folks:


    A student of mine noticed these buds growing along the branches of Hylocomium splendens. I've rarely observed sporophytes on H. splendens so I was wondering if these "buds" would develop into sporophytes or new branches? Inside some of the buds were these little brown structures with a netted pattern. See attached photos.

    So if these buds have the ability to grow new plants are they Gemmae?

    They are probably antheridia -  the male structures. Look inside and there should be sacs of sperm. If not male structures, they are the female structures called archegonia, that will grow into capsules. Another moss where they are quite evident is Orthotrichum lyellii, which has separate male and female plants.
