NEW OR CRITICAL FUNGI. 147 



with potassium hydrate, 70-120 x 5-7 /*, sometimes arranged in 

 fascicles; asci clavate, apex narrowed and blue with iodine; pedicel 

 elongated, often crooked, 100 x 8-9 fj.; spores 8, irregularly 2- 

 seriate, straight or slightly curved, hyaline, smooth, for a long time 

 continuous, finally 1-septate, 12-20 x 3 /a (averaging 15 /x long); 

 paraphyses hyaline, 2-3 /x thick, almost cylindrical. 



Peziza Rupatorii Schw. Syn. Fung. 174 (1834). 



Trichopeziza Eupatorii Sacc. Syll. no. 1758. 



On dead stems of Eupatorium purpureum, Bethlehem, U.S.A. 

 {Schweinitz). 



The above diagnosis is drawn up from a specimen named by 

 Schweinitz, and now in Herb. Berk., Kew. The clear purple colour 

 assumed by the external hairs when treated with potassic hydrate 

 is very striking. Tliere is not a single point of specific relationship 

 between the present species and Peziza soienia Peck. (= Solenopezia 

 solenia Sacc. Syll. no. 1981), as has been suggested. 



Barlaea subaurantiaca Mass. Ascophore subsessile, con- 

 tracted into a very short, stem-like base ; at first convex and 

 closed, then expanding and becoming plane, the entire margin 

 frequently drooping ; disc umbilicate and usually furnished with 

 a few radiating shallow furrows, tan-colour with a tinge of orange ; 

 externally whitish, very minutely scurfy, about 1 cm. across ; 

 excipulum formed of densely interwoven, septate hyph« about 

 6-7 p. thick, cortex pseudo-parenchymatous, and running out into 

 minute, irregular groups of cells that give the scurfy appearance to 

 the outside; asci cylindrical, apex subtruncate, base narrowed into a 

 long pedicel, 8-spored; spores obliquely 1-seriate, hyaline, 1-guttu- 

 late, rather coarsely warted, globose or subglobose, 14 p. diameter; 

 paraphyses septate, the clavate tip 7-8 /x thick. 



On the ground. Hamilton, Victoria. 



Allied in size and habit to BarUen recurva Berk., from Tas- 

 mania, but distinguished by the smaller spore- and the orange-yellow 

 disc. 



Erinella Novae-Zelandiae Mass. Gregarious, narrowed below 

 into a short stem like base, clavate and closed at fir--t, then 

 expanding and becoming pear-shaped, 2-3 mm. across; disc con- 

 cave, pale yellow, externally tawny, densely clothed with septate, 

 obtuse, cylindrical, brown, thin-walled hairs, 60-80 x 4-5 p., 

 usually rough with minute particles of lime ; hairs forming the 

 margin longer and pale, except at the tip ; excipulum parenchy- 

 matous, cells 6-9 p. diameter; asci clavate; apex broad and very 

 obtuse, tapering below into a slender, usually crooked pedicel, wall 

 thick except at the apex, 8-spored ; spores arranged in a parallel 

 bundle, very long and narrowly clavate, apex 5 /x thick, rounded, 

 and gradually tapering to the pointed base, multiseptate, hyaline, 

 smooth, straight or slightly curved, 85-95 p- long ; paraphyses 

 septate, hyaline, not thickened at the tip, 2^-3 p thick. 



On dead wood and bark. New Zealand. 



A very beautiful species, superficially resembling Lachnella 

 'pulvendenta, but rather larger, and with very different spores,
