SCLEROTINIA. 281 



Specimens examined in Madame Libert's Crypt. Ard., n. 326, 

 also Berkeley's specimens of P. postuma. 



Sclerotinia Candolleana. Fckl., Symb. Myc., p. 330 ; 

 Rehm, Krypt.-Flora, Disc., p. 810 ; Sacc., Syll., viii.n. p. 807. 



Ascophores 1-4 springing from a small, externally black 

 sclerotium 3-4 mm. across ; ascophore thin, glabrous, closed 

 at first, soon plane, reddish or yellowish brown, 1-6 mm. 

 broad ; excipulum and hypothecium formed of interwoven 

 hyphae; stem very slender, 5-10 mm. long, straight or 

 crooked, deep red-brown, sometimes with white down at the 

 base; asci narrowly cylindrical, 8-spored; spores 1-seriate, 

 hyaline, smooth, continuous, elliptical, ends obtuse, 7-9 X 

 3-4 p. ; parapbjses slender, slightly thickened upwards. 



Peziza De Candolleana, Lev^ Ann. Sci. Nat., ser. ii., 

 vol. xx. p. 223, pi. 7, fioj. 4 (1843). 



Hymenoscypha Candolleana, Phil., Brit. Disc., p. 114. 



On fallen leaves of sweet chestnut and oak. 



Specimen in Fuckel, Fung. Ehen., n. 2915, examined. 



Sclerotinia filipes. Sacc., Syll., viii. n. 806. 



Thin, fragile, concave, becoming plane, at length convex, 

 glabrous, white ; stem long, filiform, flexuous, same colour, 

 arising from a black, subglobose sclerotium ; spores 8, oblong- 

 fnsiform, 8 X 1 /* ; paraphyses slenderly filiform. 



Hymenoscypha filipes, Phil., Brit. Disc., p. 116. 



Growing from a wrinkled, black, nearly globose sclero- 

 tium amongst vegetable fragments in a damp situation. 



Cup about l lines broad ; stem 7| lines long. This is 

 much smaller than P. Candolleana, and the spores are alto- 

 gether diiferent. Phialea capillipes (Quelet) is grey-bistre 

 colour, and grows from a fusiform sclerotium, otherwise 

 there is a very near resemblance. 



Unknown to me. The above description copied entirely 

 from Phillips, Brit. Disc., p. 116. 



Sclerotinia fructigena. Rehm, Krypt.-Flor. Disc, 

 p.. 67. 



"Sclerctium up to 3 mm. thick, black, wrinkled, mostly 

 concentrically arranged. 

 Ascophore unknown.
