The new material now available illustrates more fully than w formerly possible the ran# «>i v a rift- 
tion in the primary appendages. The simplest type, a two-celled sterile promin e, is seen in female 
individuals ot Dtoicomyces, and in other types nuiv become complicated by further divisions, as Well ii 
by the production of sterile branches; and may remain wholly sterile, or be concerned in the form; ion 
of antheridia, or autheridial branches. The latter condition is that which is usually, though nol alwav 
found in monoecious types; in which the primary receptacle is directly concerned in tin production of 
procarps. Thus in Stigmaiomyces, or in Eucantharomy . Plate XXXVIII, the primary ap|>cndage i

Corethromyces Cryptolrii, Plate LI, fig- 3, may be taken as illustr ion ; while many members of tb 
genus Laboidbmia, in which the stalk of the perithedum is combined with that of the append :•• to 
form a pseudo-receptacle, indicate perhaps the highest development of a primary ap|>endage. This is 
especially well illustrated, for example, by L. Wcomw, Plate LXY1I, fig. 1, or 1. I. .v/*</-,/„7,>. Plat.

function is other than that formerly suggested, namely one primarily for protection, when' they an effi-

Haplemyce*, for example, inhabits a host, BUdiu*, that liv, in moist burro,, in mud or v,,t .and, and
