Hemitrichia leiotricha (Lister) G. Lister (Fig. 5)

Box B.M. 2978 [BM001247147]: scarce material, sporocarps sessile or with a short, blackish stalk. Sporotheca globose or subglobose, 0.5–1 mm diam., brown to grey-brown. Peridium yellowish and covered with dark brown amorphous granules in L.M. Capillitium yellowish with branched filaments of 4–5 µm diam., ornamentated with smooth and low, poorly emerging spiral bands (4–5), with few short, rounded or tapering free ends, up 5 µm in length. Under the SEM the spirals of the filaments of the capillitium are thick, tight, without visible ornamentation. Spores globose to subglobose, 9.5‒13 × 9.5‒13.4 µm, av. 11.2 × 11.4 µm, Qav = 1.02 (n = 25), slightly yellowish in L.M., with faint warts of irregular distribution. Under the SEM, the spore ornamentation is baculate type (Rammeloo 1974), formed by bacula of irregular distribution.

Box BM 2979 [BM001247520]: this sample contains little material. Its characteristics in L.M. are very similar to BM 2978, except for the free ends of the filaments of the capillitium, which are frequently subglobose or rounded, similar to plate 172 by Lister (1925). The capillitium is scarcely branched, 3–4 µm in diam. Under the SEM acute to blunt ends of the capillitium become visible. Spores are globose to subglobose, 7.9‒11.7(‒12) × 8.3‒11.9 µm, av. 9.8 × 10.1 µm, Qav = 1.03 (n = 20), slightly yellowish with warts in L.M. Under the SEM however, the spore ornamentation is confirmed to be similar to the type.
