Hemitrichia karstenii (Rostaf.) Lister (Fig. 4)

Samples B.M. 1489 [ BM001247518 ] and B.M. 2008 [ BM001247519 ]: the material conserved in BM is very scarce and no preparations have been made for the light microscope. We collected a small portion of the capillitium and spores and analyzed them under the SEM only. The capillitium is branched and with few free ends, filaments are 3–5 µm diam., with 3–5 tight smooth spirals bands, and irregular swellings, the latter being globose to oval up to 10 µm diam., with the same ornamentation or sometimes less marked than in the elaters. Spores are globose to subglobose, 10–14 µm diam., yellowish in mass. Under the SEM, the ornamentation is of baculate type, with abundant bacula of different sizes and irregular distribution .
