the most universally distributed form that occurs on QtUerita in the western hemisphen . r Y\\v antlie- 
ridia, instead of arising terminally from special branches, occur one to three together Mow the septa of 
branchlets borne on the branches of the inner appendage. The typical form of this speck . which <>< purs 
only in Mexico and Central America, is stout and large, sometimes more than a millimeter in length 
usually amber-brown throughout; although in a few instances the perith ium Incomes smoky brown, 
a condition well marked in material from Columbia and Costa Kica (Merlin Museum No. %7 and British 
Museum No. 521). These forms, as is pointed out below, approach perhaps too cln.lv to /,. mrlatw- 
tkeca, which is otherwise very clearly distinguished, even when it occurs in company With the present 
species on the same host. South of the Isthmus of Panama, however, material from Venezuela, Peru, 
Brazil and the Argentine, shows a distinct variation from the type; the individuals approaching the 
"flagellata" type more closely; usually smaller, sometimes not over MOO " in length, pale strav colored, 
with a contrasting black perithecial tip, and more or 1< ! strongly marked olive-brown suffusions; never, 
as far as I have seen, assuming the typical amber-brown tint. The appendaj of the- molt southern 
types are also usually more slender and tapering, and sometimes exceed the re ptaele in length. Th 
specimens from Peru with their dark perithelia and numerous divergent branches are i specially char- 
spe 
acteristic.
