 Eemarhs. — This species is closely allied to S. coraloides, but I think is 

 distinct from it.

. S. strato expanso, tomentoso, atro ; trichomatibus ramossissimis, 

 arete intertextis ; ramulis abbreviatis vel elongatis, subrectis aut varie 

 cui'vatis, apicibus obtuse rotundatis vel subacuminatis ; trichomatum et 

 ramulorum cellulis uni vel biseriatis, plerumque pachydermaticis, dilute vel 

 saturate aerugineis, enormibus, plerumque homogeneis ; cellulis termi- 

 nalibus elongatis, cylindricis, saepius nonnihil oscillatorium modo articu- 

 latis, granulosis ; vaginis sat amplis, hand achrois, vel luteo-briuineis vel 

 fuscentibus vel ferrugineis. 



Occurring in an expanded, tomentose, black stratum ; filaments very 

 much branched, closely interwoven, branches abbreviate or elongate, 

 nearly straight or variously curved, their apices obtusely rounded or sub- 

 acuminate ; cells 1-2 seriate, mostly thick walled, light or deep aerugin- 

 ous, irregular, mostly homogeneous ; terminal cells elongate, cylindrical, 

 frequently articulate somewhat like an oscillatoria, granulate ; sheaths 

 somewhat ample, not transparent, light brown, fuscous or ferruginous.

S . immersus ; trichomatibus subsolitariis, longis usque ad liiieas quatuor , 

 cylindricis, ramossissimis ; ramulis singulis ; cytioplasmate interdum 

 aerugineo, plerumque aureo-brunneo ; cellulis uniseriatis rarissime bi- 

 seriatis, subglobosis, interdum sejunctis sed plerumque arete connectis 

 et moniliformibus, modo confluentibus, hand distincte pachydermaticis ; 

 cellulis termiualibus elongato-cylindricis, saepe nonnihil oscilatorium 

 modo articulatis ; cellulis interstitialibus nuUis ; vaginis achrois, inter-

S. immersed, subsolitary, attaining a length of 4 lines, cylindrical, very 

 much branched ; branches single ; cytioplasm aerugiuous, mostly yellow- 

 ish brown ; cells uniseriate, very rarely biseriate, subglobose, sometimes 

 separate but more frequently closely united and moniliform ; terminal cell 

 an elongated cylinder, often articulate somewhat like an oscillatoria; 

 interstitial cells wanting ; sheaths transjjarent, sometimes brown, mostly 

 colorless. 



Remarks. — This species is perhaps too close to S. crameri, but appears 

 to differ from it very markedly in habit and place of growth.
