The Fern Leaf Sorus is rather opaque and so not a good subject for substage lighting. The superstage technique used here doesn't give good colors but it does render a remarkable amount of detail. A sorus is a cluster of sporangia, which are organs that produce spores.

This slide was purchased on Ebay and is part of 100 prepared slides " set B" I hope you enjoy the microscopic pictures of Fern Leaf Sorus found on this page. I believe you'll find these images of Fern Leaf Sorus to be superior to those found elsewhere!
