An intercelhdar mycelinm has been fonnd, and roundish dry spots with reddish margins are formed. Thereon tufts of short conidiophores are developed, bearing cylindrical, thick-walled, pluricellular conidia. CI. glomerulosum Sacc. {Sporidcsmium glom. Sacc, 1878, and P/eospo/v roivjhitiaaia Goebel, 1879). Cloel»eP tirst described this species as a parasite on Junipems communis. A colourless intercellular mycelium is present, and in conseciuence the needles turn brown, die, and fall oil' prematurely. On the upper side of the needle the mycelium emerges through the stomata, and forms dark-grey coils from which the grey, ovoid, pluricellular conidia are given off. Ceratophorum.
