306 FUNGUS-FLOEA. 



Echinella senecionis. Mass. 



Gregarious, sessile, suberumpent, closed at first, then 

 becoming almost plane, entirely black, closed when dry, up 

 to ^ mm. across, externally, and the margin clothed with 

 rigid, blackish-brown, smooth, almost opaque spines, these 

 are longest and most numerous at the margin, where they are 

 1-2-septate, rather abruptly acuminate, 40-50 X 6-7 /x, ; 

 cortex parenchymatous, cells brownish, 6-8 /i, diameter ; asci 

 oylindrio-clavate, apex slightly narrowed, base stout, 8- 

 spored ; spores 2-seriate, hyaline, narrowly cylindrical, 

 sometimes with a tendency to become clavate, usually 

 2-guttulate, for a long time continuous, finally septate, 

 8-14 X 2 /i ; paraphj'ses slender, slightly thickened 

 upwards.

On dead herbaceous stems. 



Peziza senecionis, Cke. & Phil., Grev. V. G., p. 104. 



Distinguished among allies by the short spores. In the 

 original description the spores are said to be continuous, but 

 in a specimen in Kew herbarium, communicated by Spegaz- 

 zini, I find some of the spores 1-septate, and the same is the 

 case in the specimens contained in Speg., Dec. Myc. Ital. 

 n, 19, also in the type of Cke. & Phil. 



Echinella Crosslandi. Mass. 



Gregarious or sometimes almost crowded, sessile, base 

 narrowed, closed at first then expanded, but the margin 

 remaining more or less erect, about 1 mm. across ; disc 

 pallid, externally pale brown, becoming buff or pale drab 

 when dry, densely villose, hairs thin-walled, cylindrical, 

 obtuse, minutely rough 70-125 X 4-5 yii, straight, sparingly 

 or not at all septate, yellow-brown, tips paler ; cortex paren- 

 chymatous, cells irregularly polygonal, 5-6 m diameter ; asci 

 cylindric-clavate, apex slightly narrowed, 8-spored ; spores 

 irregularly 2-seriate, smooth, hyaline, elliptical, multiguttu- 

 late then 3-septate, 12-15 X 4/*; paraphyses slender, hyaline, 

 cylindrical. 



On decorticated wood.
