 8-11 fjL. On decaying capsules of Liquidambar, Naamans Creek, Delaware.

13. STROMATINIA Boud. Hist. Class. Discom. Eu. 108. 1907. 



Stroma of two types, a thin, black, subcuticular sclerotium 

 covering or manteling the affected portion of the host from which 

 the apothecia are produced and small, black sphaerules borne 

 free on the mycelium and not producing apothecia; spermatia 

 globose. 



Apothecia as in Sclerotinia; spores hyaline, simple.

1. Stromatinia Smilacinae (Durand) Whetzcl, Mycologia 37: 



674. 1945. (Plate 96.) 

 Sclerotinia Smilacinae Durand, Bull. Torrey Club 29: 462. 1902. 



Sclerotia small, not exceeding 1-2 mm. in diameter, irregu- 

 larly globose, aggregated and sometimes coalesced into a thin, 

 crust-like mass 1-2 cm. in diameter. 



Apothecia scattered, or gregarious, long-stipitate, fleshy- 

 leathery, closed and subglobose at first, expanding to cup- 

 shaped, finally becoming campanulate, usually with a depression 

 in the center, sometimes contorted or irregular, reaching a 

 diameter of 1-3 cm., bright cinnamon-brown, externally smooth; 

 stem reaching a length of 2-6 cm. and a thickness of 2-3 mm., 

 tapering downward, sometimes tomentose below; asci narrowly 

 cylindric, apex rounded, reaching a length of 120-140 /x and a 

 diameter of 6-8 m, 8-spored; spores obliquely 1 -seriate, hyaline, 

 simple, smooth, narrowly ellipsoid, often with two oil-drops, 

 4-5 X 12-15 m; paraphyses filiform, scarcely thickened above. 



On dead rhizomes of Smilacina racemosa buried in rich humus.
