196 The North American Cup-Fungi 



Distribution: Ontario, Canada; also in Europe. 



Illustration: Schmidel, Ic. PI. 69,/. 1-13. 



On May 23, 1919 an excellent specimen of this species was 

 received from Prof. J. H. Faull of the University of Toronto, 

 Toronto, Canada. Although previously recorded from Ottawa, 

 this is the only fresh specimen of the species seen by the writer. 

 American specimens agree well with Schmidel's excellent illustra- 

 tions except that the hymenium in our specimen is much more 

 expanded which is probably due to a more advanced stage of 

 development. This is a part of the material reported in My- 

 cologia (11: 293. 1919) as Bulgaria platydiscus Casp. which is 

 said to differ from B. globosa in the size of the spores. The 

 writer has had no opportunity to study living material of either 

 species.

Apothecia gregarious or cespitose, sessile or more often short- 

 stipitate, attaining a diameter of 2-3 cm. at first closed, finally 

 opening and becoming shallow cup-shaped, with the margin 

 incurved, externally blackish-brown and covered over with 

 clusters of hairs, the substance tough, internally with a gelatinous 

 layer several mm. thick, giving to the fresh plants a rubbery 

 consistency, on drying becoming coriaceous and strongly wrinkled 

 as a result of the gelatinous tissue within; hymenium slightly 

 concave, pale-reddish or reddish-brown; stem reaching a length 

 of 1 cm. and a diameter of 4-5 mm., attached below by means 

 of a dense mass of black mycelium which reaches a diameter of 

 7-8 m; hairs blackish-brown, similar to the mycelium at the 

 base of the stem but shorter; asci cylindric above, gradually 

 tapering below into a long stem-like base, reaching a length of 

 275-300 /x and a diameter of 12-14 /x; spores 1-seriate, ellipsoid, 

 with the ends strongly narrowed, hyaline, granular within, 

 10 X 20 ^t; paraphyses filiform, scarcely enlarged above. 



On the ground in woods attached to sticks which are buried 

 under leaf-mould and soil.
