REVISIONS OF CEYLON FUNGI. 4l35 



F. Theisseji, in "Novitates Riograndensis," Annales Myco- 

 logici, Vol. VI., p. 350, records Rosellinia Desmazierii (B. & 

 Br.) Sacc. var. acutispora Theiss., which is said to differ from 

 Ros. bunodes (B. & Br.) Sacc. in having the perithecia not 

 verrucose ; it evidently differs also in the size of the spores, 

 which are only 42-50 X 6-7 /^. 



F. V. Hohnel, in ." Ergebnisse der Bot. Exped. d. k. Acad. d. 

 Wissensch. nach Sud Brasilien, 1901 ; Eumycetes et Myxoniy- 

 cetes," p. 25, notes the relationship of Rosellinia goliath (Speg.) 

 V. Hohnel to Rosellinia bunodes (B. & Br.) Sacc. The latter 

 species apparently differs in its smaller perithecia, which are 

 only warted, not spinous, and in its smaller spores wliich, 

 although they have the same tapering points, are only two- 

 thirds the size of those of the former. The bases of the warts 

 of Rosellinia bunodes are more or less lozenge-shaped, 0*2 to 

 0"4 mm. across, and the warts are not more than 0"1 mm. high. 

 Rosellinia echinata Massee is apparently closely allied to 

 Rosellinia bunodes. 



66. — Rosellinia emergens (B. & Br.) Sacc. 



Sphceria {Byssisedce) emergens B. ^ Br., Fungi of Ceylon, 

 No. 1089. Jo urn. Linn. Soc, XIV., p. 125. 



Perithecia gregarious, embedded to about half their height 

 in closely interwoven purple-brown hyphse, conoid, about 0*8 

 mm. diameter at the base, 0"9 mm. high, with an abruptly 

 conical ostiolum, 0"1 mm. high, black, smooth, carbonaceous. 



Asci clavate, eight-spored, sporiferous part 160 X 30 M, 

 shortly pedicellate, apex abruptly cylindrical and thickened ; 

 spores obhquely biseriate. Spores f usoid or broadly cymbiform , 

 straight or slightly curved, ends subacute, contents granular, 

 blackish-brown, covered with a thin hyaline film which is 

 most evident as a small cap at each end, 60-70 x 10-13 /*. 

 Paraphyses not seen. 



Rosellinia emergens var bambusicola Theiss. (Ann. Myc. , VI. , 

 p. 351) appears to have perithecia of a different shape, 

 " depresse globosis," and much broader spores (15-22 H-). The 

 above description is drawn up from Berkeley and Broome's 

 type specimen in Herb. Peradeniya.
