DASYSCYPHA. :331 



clavate, apex obtuse, pedicel short, stout, 8 spored ; spores 

 irregularly 2-seriate, smooth, hyaline, elliptical, ends acute, 

 straight, 1 -septate at maturity, 9-11 X 3 //.; paraphyses 

 lanceolate, apex acute, 3-5-septate, often slightly constricted 

 at the septa, half as long again as the asci, 5-6 p at the 

 broadest part. 



On dead, fallen oak leaves. 



The present species, found by Mr. H. T. Soppitt, near 

 Bradford, Yorks, is amongst the most beautiful and distinct 

 of the white species of Dasyscypha, distinguished by the 

 large, quadrate cortical cells, septate paraphyses, and fusi- 

 form, 1 -septate spores. 



Dasyscypha filicea. Sacc., SylL, viii. n. 1879.

 slightly thickened at the tips, minutely rough, 40-70 X 5 /A; 

 cortex parenchymatous, cells elongated in the direction from 

 base to margin, 6-8 x 3-4 p.; asci narrowly clavate, tip 

 narrowed, 8-spored; spores 2-seriate, distinctly fusiform, 

 ends acute, 1-septate, hyaline, 15-18 X 3 /x; paraphyses

Lachnella filicea, Phil., Brit. Disc., p. 254. 



On the under surface of the frond, and on the rachis of 

 ferns. 



Distinguished among the white species by the large, 

 1-septate, fusiform spores having sharp ends, and the more 

 or less capitate, external hairs. 



Type specimen examined. 



In giving localities for this species, Phillips says, " Dunedin, 

 N.B. ! in Herb., Kew "; on turning to this species, I find that 

 the specimen is from Dunedin, New Zealand, Dr. Berggren, 

 n. 400. As Phillips also gives Chedder, collected by 

 C. Bucknall, it is included here. 



Dasyscypha crucifera. Sacc., Syll., n. 1833. 

 Gregarious, stipitate, snow-white or with a very slight 

 tinge of yellow on the stem ; clavate, often hemispherical ; 

 excipulum composed of more or less parallel, elongated cells,
