There is certainly nothing here to justify the wholesale 

 transference of this and others of von Schweinitz's species 

 to Sporocybe as is done by Saccardo in Sylloge Fungorum. 



The species is near P. byssotdes, but may be distinguished 

 by the scattered and shorter, less tapering, conidiophores and 

 by the fact that the substratum is not blackened. 



6. Periconia Palmeri sp. nov. 



Substratum not blackened ; conidiophores few, scattered, 

 rather short and stout, dark brown, opake, continuous or 

 once or twice obscurely septate, slightly tapering upwards, 

 150-300 /j. high, 18 ;jl wide at the base; capitulum large, ob- 

 lately flattened, 60-70 x 80-100//. Conidia globose, brown, 

 tuberculate, 16-18//. 



On dead hanging twigs and leaves of Junipcrus Virgini- 

 ana, Stanford, Conn., October 27, 1901, Mr. L. M. Palmer. 



A very distinct species well characterized by its large tub- 

 erculate (not echinulate) conidia and short, thick, scattered 

 conidiophores. It is probably a saprophyte but it occurs in 

 connection with a peculiar dying of the twigs of the common 

 red cedar. 



7. Periconia opaca Cooke, Grevillea, 16: 79. 1888. 



Conidiophores gregarious, erect, 3-4-septate, simple, dark 

 brown, opake; capitulum subglobose, composed of 5 or 6 

 conidia; conidia globose, dark brown, opake, smooth with a 

 minute apiculus below, 12-15 I 1 - 



On leaves of carices, So. Car., Ravenel, no. 3140. Not 

 seen by me. 



8. Periconia Langloisii sp. nov. 



Blackening the substratum over larger areas ; conidiophores 

 densely gregarious, cespitose, several from a common base, 

 very slender, almost thread-like, occasionally septate, sub- 

 pellucid, light brown, about 100 x 2]/ 2 fi. Capitulum small, 

 globose, yellowish-brown, deciduous, composed of densely 

 agglutinated conidia that are not readily separable, about 

 12-20 // ; conidia globose, smooth, light brown, translucent, 

 about 2 fi. 



On dead stems of Androfogon, Louisiana, Langlois, no.
