about S iiiic. in thickness in the middle and narrower at each 

 end ; the basal segment hyaline and truncate, the apical ex- 

 tremity obtuse. (Fig. 9.) 



Growing on old pod of Tecovw radicans. The young spores 

 are hyaline and continuous, like their long, slender pedicel, 

 but septa soon appear, and the fully matured spore is brown 

 and uniformly 7-septate. 



b. Spores coiled / '2 litnes. 



2. Hei.icoma aivibikn.s, Morg., n. sp. Effused, forming a 

 brown hirsute stratum. Hyphse brown, creeping, septate, 



with ascending, 

 flexuous, fertile 

 branches, bearing 

 a few scattered 

 spores on minute 

 lateral teeth, 

 spores hyaline, <S- 

 septate, the septa 

 sometimes indis- 

 tinct; coiled about 

 I '.- times; the coil 

 14-17 mic. in di- 

 ameter; the 

 thread 50-60 mic. 

 in length ; about 

 6 mic. in thick- 

 ne.ss ; the inner extremity obtuse, the outer oblicjuely acute. 

 (Fig. 10.) 



Growing on the inner bark of .-^cer saccharinuni. The spore 

 is at first hyaline and continuous ; the septa appear one after 

 another until the fully grown spore is uniformly 8-septate. I 

 sometimes find t)ld specimens in which the spores are tinged 

 with brown and have added a few half septa, so as to appear 

 9-12 septate. This is a common species. 



3. Hhijcom.x POi,YspoRi':\i, Morg., n. sp. IvfTused, form- 

 ing a thin, rose-colored .stratum. Hypha' intricately nuich 

 branched ; the branches .short, thick, hyaline, covered every- 

 where ])y the dense layer of spores, which grow on minute 

 obtuse processes. Spores hyaline, i2-i5-.scptate, coiled about
