(4–12 μm), thick-walled bodies, with a black or dark brown pigment (sclerotic bodies) (Fig. 31-4). They multiply by cross-wall formation or splitting rather than by budding. These structures are also demonstrable in histopathologic sections. A hypha consists of one or more cells surrounded by a tubular cell wall. In most fungi, hyphae are divided into cells by internal cross-walls called "septa" (singular septum). Septa are usually perforated by pores large enough for ribosomes, mitochondria, and sometimes nuclei to flow between cells. The major structural polymer in fungal cell walls is typically chitin, in contrast to plants and oomycetes that have cellulosic cell walls. Some fungi have aseptate hyphae, meanin…
