lifercr, this crnstifoi-m production must bo arranpfed either with the Pahndkm or 

 the Protocnccccc. The former comprehends the couimou Palmella criienta, or 

 " Gory Dew, " so called from its sanguine aspect, and also the Protococcus niva- 

 lis or red snow of the Alps or Polar regions. But these productions have their 

 globules enclosed in an envelope of gelatine, while the object here dilated upon 

 would seem to belong to the division Protococccw, forming a friable stratum of 

 globules not immersed in gelatine, and readily separable. 



Agardh has given the generic name of Chroulcpus to certain minute byssora 

 structures, which UrifEths and Henfrey in their Microtjraphic Dictionarij say have 

 been regarded "sometimes as Fungi and sometimes as ^/.f/fc," but they indicate 

 the Protococccce and name the genus Chroulcpus, but take no notice, nor give any 

 description of the individuals presumed to rank under it. The well-known learn- 

 ed and observant fungologist Mr. Berkeley has somewhat doubtfully placed this 

 persistent production under the genus Chroolepus, but in his English Flora ex- 

 presses a hope that he "shall not be accused of mischievously adding to the 

 already numerous synonyms of this little plant." He has, however, placed it as a 

 member of the Byssoidece, which he defines as "Plants of doubtful affinity, related 

 to the Fungi." Notwithstanding this intimation, I have in my Botany of Malvern 

 Hills, placed the little plant mentioned in this paper under the Protococcecc, and 

 have had the temerity not only to give it generic rank, but a specific title also, as 

 under. 



Jolithus. — Forming a friable stratum of globules not immersed in gelatine, 

 the filaments crowded together, and enclosing concatenated coloured globules. 



Jolithus lichcnoideus (Lichen Jolithus, Linn.) Filaments tufted, erect, very 

 short, orange red, dichotomous, the enclosed globules longer than broad. 



Appearing like a red crust or powder, on rocks and stones, and when lubbed 

 or moistened emitting a fragrant violet-like scent. It colours rocks and stones 

 in Switzerland in damp and shady places with a gorgeous colour, but in England 

 it is most abundant on the walls of old churches near the coast, or on tombstones 

 of great age in churchyards. Where it has once fixed itself the Jolithus remains 

 as permanent as the rock or building on which it grows and extends. 



I have noticed this Algal in great abundance in a rocky ascent between the 

 Rhone valley and the next village on the road to Zermatt ; and as it also reddens 

 the rooks to a considerable extent at the base of Monte Rosa also in Switzerland, 

 I am inclined to think that the name applied to the mountain was given to it 

 from this circumstance rather than to the transient effect produced by the reflect- 

 ed rays of the setting sun. 



The walls of the churches of Wyke near Weymouth, and of Portishead in 

 Somersetshire, have portions conspicuously coloured by the extended crust of this 

 alyal. 



It must be admitted that the red globules when mature have a considerable 

 resemblance to those of Hcematococcus, which some botanists regard the same as 

 Palmella, but I have never seen them duplicated as those of Hwmatococcus are, 

 and the latter is an inhabitant of water. In fact the globules differ but little 

 from those of the famed " red snow," which has been placed in different genera as
