ニシムラエゾヒメヤバネゴケの胞子体について

抄録

The sporophyte of Hygrobiella nishimurae N. Kitag. is newly described as follows : seta up to 3-5 mm long, 190-220μm broad, consisting of 8 outer and 4 inner cells (Cephalozia type); capsule blackish-brown, broadly oblong-ovoid, 280-320 × 260-280μm, 4-valved to base, its wall 2-stratose, epidermal cells subquadrate to short-oblong, 12-24×26-32μm, with well-developed nodular thickenings, (0-) 1-2 (-3) per face of longitudinal and transverse walls, inner cells elongated narrower, 32-66×12-16μm, with semiannular bands which are often reduced to nodular thickenings. Elaters 100-160μm long, 5-8μm wide, with 2 spirals, the spirals reddish-brown, slender, 3-3.5μm broad ; spores reddish-brown, 18-22μm in diameter, finely papillose. It seems that there is no remarkable qualitative difference between the sporophyte of Hygrobiella nishimurae and that of H. laxifolia.
