After Sachs. Brefeld. The first beginnings of the compound sporophores are small spherical bodies produced by the interweaving of copiously branched mycelial hyphae. The weft of primordial hyphae thus formed is at first close and colourless and contains air ; but the branches at the periphery soon develope into stout hairs with tooth-like branches and brown membranes, which cover the surface as a brown felt. With this covering the small sphere grows by constant formation of new elements in the interior of the hyphal weft into a thick cylindrical or obconical body about 6 mm. in height. The differentiation into the parts which are found at maturity begins before the body has reached half its ultimate size and advances with the general growth. The first separation is seen in the internal primordial tissue which is originally uniformly white in consequence of the air contained in it, in other words in the opaque primordial tissue, and the result is that a zone between the periphery and the middle becomes a gelatinous felted tissue free from air and therefore transparent. The differentiation of this zone begins above the base of the body; the z
