Lachnopsis sp. "branched dark" P.R. Johnst.
Lachnopsis sp. "branched dark"
Small apothecia develop in groups from a branched stipe, dark hairs on a pale receptacle, forming on Dicksonia, on dead pinnae on otherwise living fronds, or in pale patches of dead fronds.
Apothecial cups less than 0.5 mm diam., forming in groups on branched stipes, with up to 15 cups arising from a common base. Hymenium and surface of receptacle pale, off-white, with stiff, black hairs on receptacle and stipe. When dry, hairs cover the hymenium. Excipulum of hyaline, short-cylindric cells with slightly thickened, agglutinated walls. Hairs 60-90 x 3-5 µm, straight, tapering to pointed apex, dark brown, roughened all over. Paraphyses 2 µm diam., taper to small rounded apex apex, about same length as asci. Asci about 30-40 x 5 µm, cylindric, apex broadly rounded, wall slightly thickened, J+ reaction faint and diffuse, extending right through the wall. Ascospores 12-18 x 1-1.5 µm, fusoid, tapering uniformly to both acute ends, radially symmetrical, straight, 0-septate.
