Fig. 1.— Germinating basidiosporcs of Lenzites trabea on malt agar. Fig. 2. — Oidia of Lerizites 
trabea from secondary aerial mycelium on malt agar. Fig. 3.— Stages in formation of 
chlamydospores upon 'submerged mycelium of Lenzites trabea in malt agar. Fig . 4. — Chlamy- 
dospores and chlamydosporelike bodies of Lenzites trabea upon submerged mycelium in malt 
agar, one of them germinating. Fig. 5.— Germinating basidiosporcs of Tramestcs scrialis on 
malt agar. Fig. 6.— Stages in formation of chlamydospores of Trametis serialis on malt agar. 
Note contraction of protoplasm and formation of walls. Fig. 7. — Chlamydospores of Trametes 
serialis from submerged mycelium in malt agar. Fig. S.— Chlamydospo're of Trametis scrialis 
on aerial mycelium in malt agar tube, showing old walls. Fig. '9. — Germinating chlamydo- 
spores of Trametes scrialis on malt agar. Fig. 10.— Irregular hypha from tertiary mycelium of 
Trametes scrialis at top of agar slant culture. Fig. 11. — Sprouting of clamp of Trametes serialis. 
Fig. 12. — Clamps, anastomosing of hypha. 1 , and other irregularities from agar slant cultures of
