Gregarious in. across. 
Lycoperdon perlatum, Pers. Syn. 145 ; Mass., l.c., p. 10. 
Lycoperdon gemmatum, Batsch. Elen, p. 147 ; Mass., l.c., p. 10. 
These two species should be kept distinct. 
Puccinia Bupleuri, Bud. in Linncea iv., 514. 
Epiphyllous and caulicolous. Sori oblong, gregarious, soon 
fissured, and surrounded by remains of the epidermis, dark brown, 
rather small. Telentospores elliptical, uniseptate, brown, 
26-40 X 18-30 p. — Corda Icon. iv.,/. 50. 
Puccinia Bupleuri falcata, Winter in Rabh. Krypt. FI. i., 212. 
On Bupleurum. tenuissimum. Walton on the Naze. Aug., 1887. 
(R. Paulson.) 
Valsa (Calospora) alnicola, C. fy Mass. 
Perithecia few, circinating, nestling beneath the elevated bark, 
which is at length pierced by the short ostiola. Asci clavate, 
octosporous. Sporidia cylindrical, obtuse, slightly curved, tri- 
septate, hyaline, 25 X 8 p. 
On branches of Alnus autumnalis. Kew. 
2661. Chsetosphseria pileo-ferruginea, Cronan. Sacc. Syll. 3216. 
Sporidia lanceolate, uniseptate, 4-6, nucleate, hyaline, 
45-50 x 8 p. 
On roots of Calluna. Near Carlisle. (Dr. Carlyle.) 
The perithecia being smooth, and the sporidia with scarcely any 
tinge of colour, this species should have been placed in Byssosphceria 
in our “ Synopsis Pyrenomycetum.” There are faint indications 
that the sporidia may become 3-5 septate, but the specimens were 
clearly not fully mature. 
Cucurbitaria Aspegrenii, Ces. Not. Sac. Syll, 3987. 
Sporidia 7 septate, muriform, brown, 48-53 X 12-14 p.

No. 5715. 
Sporidia 100 x 35 p, tips pale or colourless. 
On pine wood. Scarboro’. (G. Massee.) 
Also found on Fries’ specimens of Lophium mytilinum , in Scler. 
Suec. No. 10. Not hitherto recorded as European. We cannot 
accept Saccardo’s alteration of the generic name of Ostreichnion to 
Ostreion , however vicious the former may be, after it has been ac- 
cepted and adopted for so many years. Note, for example, the 
Cinchona v. Chinchona discussion in 1866. “ In these kinds of 
questions it must be borne in mind, first, that the fixity of names 
is of superior importance ; secondly, that a botanist has the right 
to construct a name in any way he pleases, something in the form 
of a man’s name, for instance.” See Commentary on Laws of 
Nomenclature , 1868.
