Trichia intermedia L.F. Celak (Fig. 10)

Box B.M. 2907 [ BM001247525 ] (type): the material on two pieces of bark is scarce. From the few sporocarps (sessile or with short stalk) a small sample of capillitium and spores was taken for study by LM and SEM. The capillitium is formed by yellowish elaters 4–5 µm in diam. Under SEM elaters show 3–4 smooth and not very tight spiral bands, with pointed free ends (up to 20 µm in length). Sometimes before the apex a globose broadening is visible. Spores are globose, (10‒)10.1‒13.6 × (10‒)10.1‒13.6 µm, av. 11.8 × 11.8 µm, Qav = 1 (n = 25), yellowish in transmitted light and densely warted. Under SEM the spore ornamentation is of the pilate type and tight. Sometimes interconnected at the top of pila forming small reticulae .
