The general features of the sexual organs of Eurotium herbariorum weredescribed by de Bary in his classical researches of 1870. He distinguisheda coiled, septate archicarp, and saw that its tip fused with a comparativelystraight antheridial hypha, the membranes between breaking down, and herecognized that from it the asci are ultimately derived. More recently it has been shown that the archicarp of Eurotium ismade up of three parts: a multicellular stalk, a unicellular oogonium, anda unicellular trichogyne. In E. herbariorum these parts may be clearlydistinguished (fig. 30^), but they are not always equally definite
