FIG. 3. — Spores photographed under scanning electron microscopy to reveal the anisosporic condition observed in individual capsules of two Homalothecium Schimp. species (H. sericeum (Hedw.) Schimp. s.s. and H. meridionale (M. Fleisch. & Warnst.) Hedenäs) from herbarium samples: A, B, from capsules of H. sericeum s.s. (LISU 262054 and LISU 264096); C, D, from capsules of H. meridionale (LISU 265335 and LISU 266570). Scale bars: 10 µm.
