1 86 Massee and Crossland : New British Discomycetes. 



matous ; asci cylindric-clavate, about 60x7-8 /x, 8-spored, plug 

 blue with iodine ; spores 2-seriate, cylindrical or eylindric-fusoid, 

 usually very slightly curved, hyaline, continuous, 2-4-guttulate, 

 1 1 -14 x 3*5-4 f* ' paraphyses slender, cylindrical.

Pseudohelotium vitreolum Sacc, Syll. VIII. , n. 12 17 (1889). 



On dead blackberry stems ; Queen's Cottage Grounds, Kew 

 Gardens (G. Nicholson). 



Allied to Dasyscypha hyalina, but readily distinguished by 

 the larger spores. Karsten's specific name is very apt, as when 

 quite fresh the cups present the appearance of being made of 

 glass, and are almost transparent. 

 Dasyscypha Richonii (Bond.) Massee. 



Gregarious, entirely rose-pink or with the disc darker and 

 dingy, sessile, closed at first, then expanding until almost plane, 

 rather fleshy, about V3 mm. across; hairs at the margin thin- 

 walled, acute, septate, tinged rose-colour, 50-120x3-4 /x, those 

 on the outside of the ascophore smaller ; asci subcylindrical, 

 apex slightly narrowed, 8-spored, 40-45 x 5-6 \x ; spores hyaline, 

 continuous, elliptical, minutely 2-guttulate, 6-7 x 2-2*5 /* > para- 

 physes filiform, tips not thickened ; cortex parenchymatous, 

 cells small, elongated in the direction from base to margin.

On rotten wood, Mulgrave Woods, Whitby ; Y.N. U. Foray, 

 September 1900 (J. Needham). 



This beautiful little fungus has only, previous to its discovery 

 near Whitby, been recorded from France, where it was found 

 growing on rotten poplar wood. Readily distinguished by its 

 rosy colour. The wood on which it is growing is also tinged 

 pink when the fungus is developed in abundance, and more or 

 less crowded. 



Dasyscypha ci tricolor B. & Br. 



Gregarious, sessile, base slightly narrowed, finely tomentose, 

 marginal hairs best developed, 40-50 x 2*5-3 /x, citron yellow, or 

 with just a tinge of green, up to 0*5 mm. across ; asci sub- 

 cylindrical, 80-90 x 10 [j., apex thickened, plug blue with iodine, 

 8-spored ; spores cylindrical, ends rather pointed, 2-4-guttulate, 

 17-21 x 4-4*5 /x ; paraphyses filiform, sometimes branched.
