BADHAMIA. 



BANGIA. 



JBactridium can- 



didum. 



Magnified 200 

 diameters. 



scopic plants of tufted habit, growing upon 

 decaying wood, old bark, &c. ; 

 white at first, but coloured Fig. 51. 

 subsequently by the condensa- 

 tion of the grumous contents 

 of the spores. Three species 

 are recorded as British : 



B. Jlavunij Kze. On elm 

 stumps. 



B. Helvellte, B. and Br. 

 On Peziza testacea. 



B. atrovirens, B. On dead 

 stumps.

BADHA'MIA, Berk. A genus of Myxo- 

 gastres (Gasteromycetous Fungi), consisting 

 of little variously-coloured sacs growing in 

 patches on decayed oak-branches, &c. ; allied 

 to Physarum, but remarkable for the spores, 

 at first enclosed in a common sac, adhering 

 in clusters. Filaments of the capillitium 

 broad.

B^EOMY'CES, Pers. A genus of Li- 

 chenaceous Lichens. 



The four species are found on the earth 

 and stones.

BAIRDIA, M'Coy. A marine genus of 

 Bivalved Entomostraca, belonging to the 

 Ostracoda and related to the Cypridae. 

 First known by its valves alone, winch are 

 subtriangular. Abundant, both recent and 

 fossil ; found also in the Palaeozoic rocks.

BALANI'NUS, Germ. A genus of Co- 

 leoptera, of the family Curculionidse. 



B. nucum is well known as depositing its 

 eggs in nuts, upon which the larva lives, and 

 from which it escapes, leaving a hole. 



The beetle is 1-3" long, with a rostrum 

 nearly as long as the body. Larva white, 

 with a brown head and strong jaws.

BALANTID'IUM, 01. & L. A genus 

 of Infusoria, fain. Bursarina. 



Like Kondylostoma, but the body dilated 

 behind and narrowed in front. 



B. entozoon. In the human intestines, 

 and those of frogs. 



BIBL. 01. & Lachm. In/us, p. 227. 



BALSAM (Canada). The liquid resin of 

 the Pinus Balsamea. This is the ordinarily 

 used and best medium for the preservation 

 of dry transparent objects. The more co- 

 lourless it is, the better. It should be kept 

 in a wide-mouthed bottle, covered by a large 

 cap, fitted by grinding. A piece of iron- wire 

 should be kept in the bottle, so that the 

 desired quantity can be easily removed. It 

 becomes thicker by keeping, but may be 

 rendered thinner by mixture with oil of tur- 

 pentine and digestion at a gentle heat, or 

 with benzole. If too thin, it should be ex- 

 posed to a gentle heat in a bottle covered 

 with paper, to exclude dust. See PRESER- 

 VATION. 



BALSA'MIA, Vittadini. A genus of 

 Tuberacei (Ascomycetous Fungi), character- 

 ized by the hollows which are lined by the 

 fructifying cells not leading to the surface, 

 and its cylindrical or oblongo-elliptic even 

 sporidia. 



Balsamia platyspora occurs in different 

 parts of England, and is eagerly scratched 

 up by squirrels attracted by its strong scent.

BANG'IA, Lyngb. A genus of Porphy- 

 rese (Florideous Algae), placed among the 

 Ulveae by most authors, but stated by M. 

 Thuret to be Florideous. Species marine, 

 forming purplish, brownish-green, or red 

 tufts of filaments, upon rocks and stones or 

 on the fronds of other Algae, from 1 to 4 

 inches long, or in B. ciliaris, only half a 

 line long. Harvey admits five, three of 

 them, however, as doubtful : 



B. fusco-purpurea, Dillw. Brownish 

 green or purple glossy, several inches long ; 

 near highwater mark. Phyc. Brit. t. 96 ; 

 Brit. Algce, t. 25 ; Eng. Bot., t. 2055 & 2085. 



B. ciliaris, Carm. Forming a minute 

 pink fringe on Zostera marina. 



B. ? ceramicola, Lyngbye. Purplish rose. 

 On small Algae ; abo'ut 1" long. 



B. ? carnea, Dillw. Pale red tufts on 

 Confervae. 



B. ? elegans, Chauv. Minute tufts 1'" or 

 2'" long, rose-red, parasitic on small Algae, 

 rare. Harv. Phyc. Brit. t. 246.
