 in the centre of a tuft of Bryum pallens). G. C. Druce, " Cerastium Holo-

Grevillea — December: — "New British Fungi," by Dr. M. C. Cooke, in- 

 cludes only one Scottish species, viz., Lacterius capsicum Schulz., sent from 

 Dumfries by Rev. J. Stevenson. 



Dr. Cooke has commenced a revised edition of his well-known "Hand- 

 book of British Fungi" in the form of an appendix to " Grevillea," but 

 paged separately, so as to allow of the work when completed being bound 

 separately. In the December number 38 species of the Leucosporous 

 Agarici are described. The advertisement states that "Comments on 

 the several species have not been attempted, since these will be provided 

 for in another work now in course of preparation by the Rev. Jno. Stevenson." 



"British Fresh-water Algae," by Dr. M. C. Cooke, has now reached its 

 sixth part ; in this are included the Ulotrichacece and the Clicetophoracea', 

 illustrated with twelve plates. 



Science Gossip, December, 1882, p. 277, Chelifer De°eerii C. Koch, new to 

 Britain, found in September on the rocks near North Berwick, among loose 

 earth in the fissures, by Mr. Henry Crowther ; verified by Mr. Cambridge. 

 On the British Bramble Phragmidia, by Mr. C. B. Plowright (1883, pp. 

 1 1 -13, with figures); records the occurrence of two species commonly con- 

 founded under the name Phr. bidbosum ; these are Phr. Rubi Pers. and Phr. 

 violaceum Schultz ; the former has the uredo-spores in small roundish sori with 

 pale yellow delicately echinulate spores, and its teleuto-spores are 3 to 8-celled 

 (usually 5 to 6-celled), with moderately long apical papilla ; the latter species 

 has the uredo-spores in rather large roundish sori, with yellow round coarsely 

 echinulate spores, and its teleuto-spores show 3 to 5 cells (4 being the usual 

 number), and the apical papilla is shorter. New British Species of Mucorini. 

 by W. B. Grove, B. A. (1. c. , p. 68), records the occurrence of Pilobolus ocdipus 

 Mont., (stem short and thickish ; swelling turbinate; columella very obtuse, 

 piercing the sporangium nearly to the summit ; spores spherical, granular, un- 

 equal in the same sporangium, 10.5-1.48., with a distinct epispore, germinating 

 easily in water ; on cow's or pig's dung) ; P. Kleinii Van T. (stem slender and 

 elongated ; swelling ovoid ; superior hemisphere of the sporangium not reti- 

 culated ; columella conical ; spores oval-oblong, variable, averaging 15 by 8., 

 not germinating in pure water ; on horse and cow dung) ; these species have 

 been confounded by observers with P. crystallinus Tode ; Pilaira Cesatii Van 

 T. — Pilobolus anomalies Cesati (resembles Pilobolus in structure of sporange, 

 ■differing in not projecting the latter explosively, and also in being much taller, 

 reaching above an inch in height as contrasted with 1 inch) ; its columella is 

 hemispherical, the lower half forming an apophysis below the sporange ; stem 

 cylindrical, not septate at base ; among Mucor on horse dung ; Chaelocladium 

 Brefeldii parasitic on Thamnidium elegans ; Piptocephalis Freseniana De B. 

 and W. parasitic on Mucor : The Flora of Ben Laoigh by P. Ewing, (I.e. , pp. 

 I 5 2_ 54) gives an enumeration of the flowering plants, vascular cryptogams, mosses 

 and Hepaticae found by Mr. Ewing on Ben Laoigh in Perthshire in the course 

 of about a fortnight in the summer of 18S2. The record will be found of interest 

 by botanists in general, and more especially by the botanists of Perthshire. 

 The Aecidium of Ranunculus Ficaria, by C. B. Plowright, (I.e., p. 160), 

 notes the occurrence at King's Lynn of uredo, and teleuto-spores of Uromyces 

 Poae Rbh. on Poa trivialis as the result of a search on the grass in the neigh-
