I was riding my bicycle around the neighborhood, when I saw a pile of ferns, lying on the grass. I picked one up, and on the underside of many pinnules, it was covered with many tiny black dots. There were around 6 to 10 tiny black dots, on many of the pinnules. One tiny black dot, is called a "Sorus". Two or more tiny black dots ( plural ), is called a "Sori". The tiny black dots, were in two rows, and one tiny black dot, was right across, from the other tiny black dot. The tiny black dots, were "leaf spores". "Individual spores are encased in structures called "sporangia", which are the dots that appear, on the underside of fern fronds". A "sorus" (pl. sori ), is a cluster of "sporangia" ( structures producing and containing spores ), in ferns and fungi. Fern: A fern, is a member of a group of about 10,560 extant species of vascular plants, that reproduce via spores, and have neither seeds nor flowers. Kingdom: Plantae.
I found a pile of ferns, lying in the grass, in a neighbor's yard.
