MS7 (Pl. XXX, below)—M61 were from pale, fluffy, slow-growing 
sectors of M26. M61 eventually split up into many pale and dark sectors. 
M62. The colony grew faster than its origin, and bore but few conidia. 
M64 (Pl. XXVIII). The colony was entirely white and fluffy from 
much aerial mycelium. It originated as a pale sector in M15-1. 
M65 and M68. These were much like M62, and maintained character 
through many transfers. 
M70. This arose where two colonies of H. No. 1 had been implanted 
just outside the edge of a colony of H. No. 1 (Pl. XXX, upper fig.). Both 
these colonies were strikingly different from the original, with much white 
and fluffy aerial mycelium Transfer from one of them showed the char- 
acter permanent through several transfers (Pl. XXV), but whether this 
saltation was actually induced by the implanting or whether a saltant was 
unconsciously selected for implanting can not be told. 
M72. Origin a most striking, fluffy, white, sterile sector. Characters 
transmitted. 
M75. A non-clumpy sector from an original that bore many clumps. 
Grew faster than its original. 
M78. Very loosely growing, stringy, white, few conidia. Character 
maintained, but the saltant soon threw many strongly contrasting light 
and dark sectors, which, however, did not show permanence after several 
transfers. 
M79. Origin like M78, but character soon lost in transfers. 
M80. Very fluffy and white and rapid-growing. 
M81. Hada narrow (1 mm.) pink line parallel to the colony-edge and 
about 5mm. from it. This line advanced, remaining narrow, as the colony 
grew. 
M83. Originated on green-wheat agar as a black irregular sector of 
smooth surface, the remainder of the original having a fluffy surface. 
M85 and M86. Two very fluffy white sectors. One of these main- 
tained its individual character; the other did not. 
M87. Whitish in its origin, and in succeeding transfers this character 
Was intensified. 
M88. Very fluffy and white; permanent through many transfers. 
M88a. A pale sector, a transfer from which threw numerous variant 
sectors, some light, some dark. 
M92. Originated in thin, sterile sectors (strands) which produced 
sclerotia at their outer ends. In transfers the colony bore many sclerotia. 
M93. White and fluffy.
