- While the Lycopodiaceae are homosporous, the Selaginellaceae are heterosporous, producing two types of spores, microspores and megaspores. The strobili of Selaginella. consist of microsporophylls and megasporophylls, bearing microsporangia with microspores and megasporangia with megaspores, respectively. Examine the prepared slide of a mature Selaginella strobilus and identify the two spore types (see text Figure 17-19, pages 406 and 407). 4. Label the microspores and megaspores in Figure 3 below. Figure 3. Selaginella strobilus l.s. Photo by Carolyn Alling 5. What type of gametophyte does the microspore give rise to?
