HOIIC: PEZIZALES, PHACIDIALES AND TUBERALES OF MINN. 99 



The above description is taken from Arthur's Report Bull. No. 

 3. p. 35. 1887. The herbarium material (Hohvay 264) does not 

 contain any spores and the external characters harmonize with 

 Sheldon 4194. which is Lachnella caiicscens (Cooke) Phill., as de- 

 determined by Dr. Durand and the writer, but the spores as de- 

 scribed above are too large for Lachnella cancsccjis (Cooke) Phill. 



4. LACHNELLA FRIES. 



Cups gregarious or solitary, fleshy-waxy, minute, sessile, hemi- 

 spherical, becoming cupulate ; exterior villose with yellowish-brown 

 hairs ; spores narrowly fusiform, smooth, hyaline, continuous or 

 two-celled. 



I. Lachnella canescens (Cooke) Phill. Man. Brit. Discom. 259. 1887. 



Pccica cajicscois Cooke, in litt. 



Gregarious or scattered, sessile, globose and closed becoming 

 cupulate but never disk-like, when dry nearly globose ; scarcely i 

 mm. wide or high ; hymenium dark brownish ; exterior densely vil- 

 lose with yellowish brown hairs, septate, blunt to 3 mic. wide, 

 woolly balls with a dark centre ; spores narrowly fusiform some 

 slightly clavate. mainly straight, hyaline, continuous (?), 9-12x2- 

 3 mic. : paraphyses filiform, slightly exceeding ascus. 



On old naked oak log; Hennepin, April 1891, Sheldon 4194. 



The specimens are dried and some, before soaking in water, were 

 nearly white tomentose balls ; after being soaked in water, they 

 turned yellow to brown with very dark centres. Some of the hairs 

 appear pale yellow with a colorless tip. Lachnella corticalis (Pers.) 

 Fr. is very closely related, differing mainly by growing on bark. 

 (Thiimen, Mycoth. univ. 280.) Lachnea hicolor (Krieger, Fung. 

 Sax. 1485) also is a close ally but the acute paraphyses are uncom- 

 mon in the Minnesota specimens and the tendency toward a pseudo- 

 septate condition places the latter under Lachnella canescens (Cooke) 

 Phill. Durand has seen some of the specimens and agrees with 

 this determination. 



5. SCLEROTINIA FUCKEL. 



Cups gregarious, springing from an under-ground sclerotium, 

 fleshy-waxy, stipitate, cupulate or funnel-shaped, large or small ; 

 stipe very long, slender, terete , immersed, tomentose near base ; ex- 

 terior glabrous and smooth ; spores elliptical, hyaline, smooth, con- 

 tinuous.
