Rysticium pulicare, Doy, on oak at Achna brook 7th April 1839 or arbustus at Dumfries 14th April 1839 Gen. Char. Perithecia elliptic or elongated, with a simple longitudinal fissure above. Sporidia cylindrical and with numerous filaments in a pale gelatinous or carmine substance, fixed at the base, slightly curved, free above. Sporidioles in one or two rows along the perithecia. If the superficial elliptic or oblong, longitudinally substituted, black, lips entire, disc circular. Scallded, and grey in different directions or nearly parallel and crowded. Sometimes a pale substitution in every thin layer is indicated but it may be merely the colour of the dead cuticle. Internally it is composed very like to an Ochyrophaea, but the cylindrical cells, decorated in carmine matter, are free and the Sporidioles (Sporidioles?) are 3-riptate. The large cylindrical cells seem to contain 2 series of cells (or Sporidioles). In a tubulus, the Perithecia were emergent, plainly raising up the cuticle previous to its rupture and they were more parallel and longer as well as more crowded. The cuticle thinner off the Perithecia's appeared rolled and lessile. Rysticium pinaster, (Schrad.), a branch of Pinus sylvestris, The Mountain 18th April 1839. Glophyllous, immutate-crowned, stalk elongated, black, opening with a linear orifice, disc black. The Sporidioles arise in each side a constricted ring off on the perithecia. The circumvallation at a little distance from the base by a singular black line. Area laminar oblong. Sporidia elliptic.
