234 FUXGUS-FLOEA. 



up to 4 mm. across ; entirely clear egg-yellow, glabrous ; 

 excipulum consisting of densely packed parallel, septate 

 hypliae that become clavate towards the exterior, 8-10 /x 

 thick at the apex, hyaline ; numerous slender, hyaline, sep- 

 tate, branched hyphae spring from the lower part of the ex- 

 cipulum and fix the fungus to the matrix; asci cylindrical, 

 apex rounded, 8-spored ; spores obliquely 1 -seriate, ellip- 

 tical, ends obtuse, hyaline, continuous, 21-23 x 11-12 /x; 

 paraphyses slender, septate, apex clavate, 4-5 jx thick, filled 

 with orange granules.

On old trunks. 



Type specimen examined. 



The cups were grouped on a spot five or six inches in 

 length and two or three inches broad, on a decorticated 

 trunk saturated with water. (Cooke.) 



Helotium scoparium. Cooke, Grev., vi. p. Ill ; 

 Phil., Brit. Disc, p. 168 ; Sacc, Syll., viii. n. 974. 



Scattered or gregarious, sessile, fleshy, globose at first, 

 then expanding until nearly or quite plane, glabrous, pallid, 

 about 1 mm. across ; excipulum parenchymatous, hyaline, 

 cells irregularly polygonal, 6-9 x 6 jx ; asci cylindric-clavate, 

 pedicel short, stout, 8-spored; spores irregularly 2-seriate, 

 hyaline, continuous, cylindric-fusoid, ends obtuse, usually 

 slightly curved, 22-25 X 5 /x; paraphyses hyaline, slender, 

 becoming slightly clavate upwards. 



On dead twigs of broom. 



Type specimen examined. 



The plants have a peculiar silvery grey stem when dry. 

 Cooke says the spores are " binucleate, at length with the 

 endochrome divided." I have observed some of the spores 

 2-guttulate, but there is no evidence of a true septum. 



Helotium badium. Phil., Brit. Disc, p. 167 ; Sacc, 

 Syll., viii. n. 1013. 



Gregarious, sessile and attached by a central point, at first 

 clavate or piriform and closed, then becoming concave, and 

 finally plane or slightly convex and discoid, rather fleshy,
