North .liiicrictiii I Iclicosporcr. 



47 



times; the coil 16-19 mic. in diameter; the thread 60-70 



mic. in length, about 5 mic. 

 in lliickness ; the inner ex- 

 tremity obtuse, the outer ac- 

 uminate. (Fig. II.) 



Growing on the inner bark 

 of Acer sacr/iaiiiiuni. The 

 rose-colored stratum is a con- 

 tinuous mass of .spores; the 

 *" t^ - 1 .spore IS quite regular in 



shape and very beautiful. 



c. Spores coiled 2-^ times. 



4. Hklicom.\ repens, Morg., n. sp. EfFu.sed, forming a 

 minutely flocculose, pinkish stratum. Hyplue creeping, sep- 

 tate, hyaline, with very short ascending branches, which are 

 covered by the abundant 

 spores. Spores hyaline, multi 

 guttulate, coiled nearly 2)- 

 times; the coil 18-21 mic. in 

 diameter; the thread 80-100 

 mic. in length, about 4 mic. 

 thick; the inner extremity ob 



tuse, the outer long and taper- ^^/ v^^^ fil- 



ing. (Fig. 12.) 



Growing on the inner bark 

 oi Acer saccharimim. The hyph^e are very fine and creep on 

 or beneath the surface so clo.sely as to be distinguished with 

 difficulty; the colored stratum is formed entirely by the 

 abundant spores. The guttuke sometimes give the spore the 

 appearance of being faintly septate. 



5. Hemcoma eimpidum, Morg., n. sp. Effused, forming 

 a minutely flocculose, pale stratum. Hyphae creeping, sep- 

 tate, brownish-hyaline, the spores borne at the apex of short 

 lateral branches. Spores hyaline, multiseptate (15-20); the 

 septa sometimes indistinct ; coiled 2-3 times ; the coil 

 20-25 mic. in diameter; the thread 80-110 mic. in length, 

 about 4 mic. thick; the inner extremity acute, the outer 

 obtuse. (Fig. 13.)
