90 ENDOSPOREAE [TRICHAMPHORA 



1. T. pezizoidea Jungh. I.e. Plasmodium greyish-white. 

 Total height 1 to 2-5 mm. Sporangia gregarious, stalked, discoid 

 or saucer-shaped, erect or somewhat inclined, 0-8 to 1-3 mm. 

 broad, 02 to 03 mm. thick, greyish-white ; sporangium-wall 

 membranous, with thin included deposits of lime equally 

 distributed, breaking up at maturity into areolae and 

 remaining attached to the capillitium after the dispersion 

 of the spores. Stalk subulate, longitudinally striate, reddish- 

 brown, translucent. Capillitium very variable, consisting 

 either of branching anastomosing colourless threads with 

 broad expansions at the axils and at the attachment to the 

 sporangium-wall, and either with or without fusiform lime- 

 knots, or Badhamia-\ike and formed of membranous tubes 

 filled with lime throughout. Spores dark or pale purplish- 

 brown, spinose, spinuloseor nearly smooth, 9 to 17 fi diam. —

PI. 72. — a. sporangia (Brisbane) ; b. capillitium and spores with fragment of 

 sporangium-wall ; c. spore (Brisbane) ; d. spore (E. Africa). 



This species often forms large plasmodia, resulting in many hundred 

 sporangia. It displays in its various forms all the types of capillitium 

 characteristic of Badhamia, Physarum and, to some extent, of Didy- 

 mium, and has been published under different names in each of these 

 genera. A large number of gatherings have now been obtained from 

 many parts of the world, having the characteristic saucer-shaped 

 sporangia* and translucent red-brown stalks, but exhibiting great 

 variety both in the amount of lime in the capillitium, and in the size, 

 colour and roughness of the spores. Junghuhn's type from Java is the 

 form with no lime in the slender threads of the capillitium, as also are 

 the types of Physarum Muelleri Berk, from Queensland, Chondrioderma 

 Berkeleyanum Rost. from Tahite, Didymium zeylanicum Berk. & Br. 

 from Ceylon, and D. australe Mass. from Brisbane. In the type of 

 Badhamia Fuckeliana Rost., from Germany, the capillitium consists 

 of membranous tubes free from lime-granules. A specimen from 

 Togo, German East Africa (B.M. 2343), collected by Staudt in 1897 has 

 Badhamia-like capillitium and dark echinulate spores 15 yu. diam. 

 A large gathering made by Mr. Petch in the Peradeniya Gardens, 



* Discoid sporangia are met with also in Badhamia orbiculata, Physarum javanicnm, 

 P. viride var. rigidum and P. polycephalum var. ohrusseum.
