34 ENDOSPORE^. [bADHAMIA. 



brown OapUlitium white, an irregular network formed of broad 

 branching lime-knots, with narrower connecting strands, chargea 

 throughout with granules of lime. Spores dark purp e-browii 

 minutely and closely spinulose all over, not clustered, 11 to IS

 Kabenh. Fungi Eur., 1968 (1854) ; in Flora (1855) p 271. Bad-

Plate IV. A.— a. stalked sporangia, x 20 (Berlin) ; J. sessile sporangia, 

 X 20 (Warsaw : Bostafinski's type) ; c. capillitium and spores of the same, 

 X 280 ; d. spore, x 600 ; ». sporangia, x 20 (England). 



The American specimens of this species from Prof. Farlow and 

 Dr. Rex are, as a rule, smaller than the European gatherings, and the 

 stalks, when present, are more slender. 



B. orbiculata Rex appears to be a variety difEering iu the shape of 

 the orbicular or discoidal, depressed sporangia. 



Hab. On dead wood.— Luton, Beds. (L:B.M.7) ; Sutton Coldfleld, 

 Stafford (L:B.M.7) ; Cambridge (L:B.M.7) ; Holland (Leyd. Herb.) ;

7. B. panicea. Eost., in Fuckel Symb. Myc, Nachtr. 2, p. 71 

 (1873). Plasmodium white. Sporangia sessile, subglobose, 04 to 

 1-2 mm. diam., scattered, or closely aggregated and angled by 

 mutual pressure, white or cinereous ; sporangium- wall membranous, 

 with innate deposits of lime-granules in dense clusters forming 

 raised warts or veins. Capillitium white, a profuse network of 

 broad or narrow bands, everywhere charged with granules of 

 lime, often densely confluent at the base, forming an ivory-white 

 columella. Spores violet-brown, very minutely warted, not 

 clustered, 11 /* diam. — Mon., p. 144, figs. 114, 116; Mass:, Mon., 

 p. 318. Physarum paniceum, Fr., Syst. Myc, iii., p. 141 (1829).

Plate IV., B.— a. sporangia, x 20 (England) ;. J. capillitium and spore?, 

 x 280 ; c. spore, x 600 ; d. sporangia broken, showing pseudo-columella, 

 X 20 ; c. sporangia of a form without columella and with a closer network 

 of capillitium, x 20. 



Badhamia verna Eost. appears to be a form of B. paxiicea ; the 

 Bpecimens in Strassb. Herb, differ from the type of the latter species 

 only in the more scanty deposits of lime, and in the narrow bands of 

 the capillitium contracting here and there into hyaline threads. These 

 characters frequently occur in normal British gatherings of B. panicea. 



Hab. Between the bark and wood of felled elm-trees, etc. Maturing 

 on the outer bark and surrounding herbage. — Batheaston, Somerset 

 (B. M. 77); Lyme Regis, Dorset (L:B.M.8) ; France (B. M. 425); 

 Germany (B. M. 424). 



8. B. lilacina Eost., Versuch., p. 10 (1873). Plasmodium 

 bright yellow. Sporangia subglobose, about 0-5 mm. diam. 

 sessile, rarely shortly stalked, gregarious or crowded and angled 

 by mutual pressure, flesh colour or whitish ; sporanginm-lvall 

 opaque from innate deposits' of lime. Capillitium flesh coloured 

 or nearly white ; a. rugged network with^large knots of irregular
