Science-gossip . Badhamia utricularis PLASMODIUM. (From Nature,) they have crept up from tlie underlying decayedvegetation for the purposes of fruiting and th^ E 3 io6 SCIENCE-GOSSIF. subsequent dispersal of the spores. Even whenfound on \\\m\g bog moss they have passed thePlasmodium oi^ feeding stage on the lower anddecayed portions of these plants. Until the spring of 1897 the researches of Britishobservers were limited almost entirely to rottenwood and decayed leaves, but from that period tillnow considerable attention has been paid to thepossibilities of straw-heaps, especially those thathave lain undistm-bed for several months. These. are easily recognised by the appearance of thesurface, which resembles old thatch. The resultsof these investigations have been most gratify-ing to those who have pursued them, for upto the autumn of 1899 they have yieldedthe previously undescribed species :—Plttjsarumstraminipes List.; Didymium Troelins List.;the first known European record of Fuligo. Badhamia utricularis. Fruitixg stage ox decayed wood.(Plwtog-aphed from Nature.) ellipsogpora List. ; and the iirst known Britishrecords of Badhamia ovispora Kacib. ; P7ii/sarumdidermoides Rost., variety lividum, var. nov. Lister(the latter being recorded in the Journal ofBotany, vol. xxxvi. p. 161). Extended and frequentobservations of the denizens of straw-heaps suggestanother peculiarity in their occm-rence, which isthat certain species affect different strata of theaccumulated material. In illustration or confirma- .tion of this suggestion the following data areadvanced. The species usually found at or nearthe surface are Thysarum caUdris List. ; P. dider-,moides Rost.; P. didermoides, var. lividum List.;Fuligo septiea Gmel. ; Didymium nigripes Fr.;Spumaria alba DC. ; Badhamia ovispora Racib.;Physarum compressum Alb. and Schw.; P. stramini-pes List.; P. erateriachea List. ; Craterium pedun-cxdatum Trent.; C. leucocephalum Ditm.; C. mutahile. Fr.; Chondriodcrma S2}umaroides Ros
