8. Rhinotrichum subalutaceum Peck, Ann. Rep. N. Y. State 



Mus. 34:51. 1881 



Stratum thin, effused, yellow-brown, alutaceous, paler on the 

 margin ; hyphae branched, intricately interwoven, smooth, septate, 

 8 — 12 jj, thick; fertile branches generally short, sometimes elongate, 

 non-septate, usually abruptly narrowed at the apex, which bears 

 the minute spicules ; spores concolorous or lighter, globose, under 

 high power of the microscope slightly roughened or echinulate, 

 8-10/x. 



On decayed wood. 



Specimens examined: Iowa, Holway 295; New York, Peck 

 (type). 



The type was collected in the Helderberg Mountains, N. Y. 

 The species is readily distinguished by the short fertile branches. 



9. Rhinotrichum repens Preuss; Sturm, Deutsch. Fl. 6: 43. 



1862 



Stratum thin, effused, white to cinereous ; hyphae creeping, sep- 

 tate, branched, 6-8 fi thick ; fertile branches erect, septate, simple, 

 equal or slightly attenuate upwards ; spores ovoid-ellipsoid, smooth, 

 12-16/x, occasionally with nucleus or with granular appearance. 



On decayed wood. 



Specimens examined: Massachusetts, Farlow (in the herbar- 

 ium of Dr. Fairman 1086). 



10. Rhinotrichum sulfureum Ellis & Ev. Bull Torrey Club 11: 



18. 1884 



Stratum effused, thin, pale sulfur-colored, nearly white at first ; 

 hyphae branched, septate, 7-8 fi thick; fertile branches erect, sim- 

 ple, septate, some gradually attenuate above, others equal or some- 

 what enlarged, several divisions bearing spicules ; spores obovoid- 

 ellipsoid, granular, 9-10 X n-15 fi- 



On decayed wood. 



Specimens examined: Iowa, Holway 296 (possibly part of 

 the type) ; New Jersey, Ellis 1662; New York, Fairman 1088. 



The New Jersey specimen is very thin, brownish-yellow, spores 

 11 X 16 fi. The color may be due to age. 



11. Rhinotrichum bicolor sp. nov. 



Stratum effused, thin, light-brown to alutaceous, dirty-white 

 on the margin ; hyphae branched, septate, hyaline or slightly col-
