GEASTER COLIFORMIS IN NORFOLK. 
before me, as I write, the inner coat or peridium shines as if it 
were covered by a very tliin coating of silver leaf, totally unlike 
any other Geaster. It has no less than 40 distinct openings 
upon it. Another character, not noticed in the text-book, is that 
the inner peridium is minutely tuberculated. Neither of these 
points struck me when I examined the specimen in the British 
Museum herbarium some years ago ; but they are both observable 
on careful observation in a specimen my friend. Prof. C. A. J. A. 
Oudemans, of Amsterdam, sent me from Haarlem, gathered by 
him in January, 1877. 
As showing the rarity of this species generally, it is worthy of 
note that Persoon, when he wrote the Synopsis in 1801, had seen 
no specimen, neither had Fries, when he wrote the Systema, in 
1829. In this country it has been found (1) by Doody, “ in the 
lane from Crayford to Bexley Common” (Ray, Synop., ed. iii., 
p. 27, 1724); (2), by Mr. Merrett, at Hampton Court; (3), on 
sandy banks at Mettingham, Suffolk, and at (Jillingham and Ears- 
ham, Norfolk, by Messrs. Stone and Woodward (Linnean Trans., 
vol. ii., p. 59) ; (4), at Hanley Castle, Worcestershire, by Messrs. 
Ballard and Rufford (Withering, ed. ii,, vol. iv., p. 460, 1792 ; 
Purton, Midland Flora, vol. ii., p. 702 ; No. 1075, 1817). On 
the Continent it has been found at Haarlem and near Darmstadt 
(Fuckel, Symb. Myc., p. 37). The figure given (in vol. ii., plate 
XV.) by Mr. Worthington G. Smith, after Sowerby, t. 313, 
conveys a very accurate idea of the general appearance and habit 
of this fine Geaster. — Charles B. Plowright, in “ Gardener’s 
Chronicle,” Oct. 2, 1880. 
Geaster coliforinis. — I have read Mr. Plowright’s communica- 
tion, at p. 439, as to Geaster coliforinis, in which he suggests that 
the plant has not been found in England since 1810. 1 am not 
aware of any published notice of it, but knowing that my friend, 
Mr. G. B. Wollaston, had found it long since that time, I made 
enquiry of him. He tells me he found it in 1830, at Westwood, 
near Southfleet, in Kent, and again between 1836 and 1840 at 
Bridgen, near Bexley, in Kent ; also that in 1840 he saw a 
specimen found by a lady at East Wickham, near Plumstead, in 
Kent ; and he adds, “ I have since foutid it recently, but when and 
where I do not recollect.” I have thought that these facts might 
be of interest to your mycological readers. — Fredk. Cdrrey,

BRITISH SPECIES OF SPIRULINA. 
Some difficulty having arisen through lack of figures of Spinilina 
whereby one species has been confounded with another, we have 
given the figures of three species on Plate 139. Of these fig. 1 
represents Spirulina tenuissima, Kutz, found in brackish ditches at 
Northfleet, Kent, of which the portion marked b is still more
