366 FUNGUS-FLOKA. 



Echinobotryum atrum, Corda, Ic. Fung., iii. f. 6 ; Sacc., Syll., 

 iv. n. 1297. 



EeMnobotryum leve. Sacc. 



Loosely gregarious, effused, black ; hyphae short, simple 

 or with very short branchlets, sparingly septate, hyaline, 

 conidia in loose racemose heads towards tip of hyphae, ovate 

 or somewhat fusoid, 12 X 6-7 p., attenuated and more or less 

 apiculate at the apex, base subtruncate, smooth, sooty, paler 

 above, with a very short hyaline pedicil. 



Echinobotryum leve, Sacc., Mich., i. p. 82 ; Sacc., Syll., iv. 

 n. 1298. 



On rotten wood, paper, dung, &c. 



Specimens agreed exactly with the description, in regard 

 to the spores, but the hyaline hyphae belonged, I fear, to a 

 fungus upon which the Echinobotryum was parasitic. I do 

 not think that E. leve is distinct from E. atrum, Ca., being 

 in fact merely " status junior" (Grove.) 



TKICHOSPOBIUM. Fr. (fig. 25, p. 358.) 



Hyphae creeping, brown or pale, vaguely branched ; 

 conidia globose or elliptical, smooth, or minutely asperulose, 

 brown, rarely almost colourless, terminal or lateral on short 

 branchlets. 



Trichosporium, Fr., Summa Veg. Scand., p. 492: Sacc., 

 Syll., iv. p. 288. 



A somewhat doubtful genus, at least so far as British 

 species are concerned, and resembling a weft of broadly 

 effused felt-like mycelium, but here and there producing 

 conidia. 



Trichosporium umbrinum. Sacc. 



Hyphae septate, brown, forming a broadly effused, inter- 

 laced stratum ; conidia rare, terminal on the branches, 

 globose, smooth, brown, 12-14 p. diameter. 



Trichosporium umbrinum, Sacc., Syll., iv. n. 1413. 



Colletosoporium umbrinum, Link., sp. pi. Fungi, i. p. 25. 



Forming a dense felt overrunning plant-pot's in a stove. 

 Also inside bark on rotten trunks.
