96 MINNESOTA liOTANICAL STUDIES. 



Spores of Hone No. 419.5 run very large and are of same char- 

 acter as in S. protracta (Fries) Sacc, but not as large as the aver- 

 age of this species. The shape of the cup and very tomentose 

 character of the specimens agree with that given for 6". iioccosa Cke. 

 Freeman's specimens contain both acute-fusiform spores and obtuse 

 elliptical in same hymenium, tlie elliptical ones being smaller. The 

 shape of the cup and tomentose character place it in 6". Hoccosa Cke.

3. Sarccscypha occidentalis (Schw.) Cooke, Mycogr. 55. fig. 96. 1879. 

 Pcziza occidentalis Schwein. Syn. I'ung. 171. no. 781. 1834. 

 Gregarious or solitary, stipitate, fleshy, cupulate ; margin entire, 



incurved ; hymenium bright scarlet, even, to i cm. in diameter ; ex- 

 terior paler scarlet to white, almost glabrous, with very short white 

 hairs, small and inconspicuous, sometimes absent altogether; stipe 

 white, tapering, 1-4 cm. long; spores elliptical, obtuse, smooth, hya-

 form, septate. 



On dead twigs, buried in the ground; Waseca, June 1891, Shel- 

 don 580; Cook, Aug. 1901, Lyon, Brand & Mac^NIillan 84; Henne- 

 pin, June 1903, Butters; Hennepin, June 1904, Lyon 838; Ram- 

 sey, July 1904, Freeman. 



The specimens were found in one collection, growing with S. 

 Hoccosa Cke. from which it differs in the almost glabrous exterior. 

 The hairs are either inconspicuous or absent. Length of stem de- 

 pends upon the depth to which the sticks upon which it grows are 

 buried. 



On wood on the ground; Cook, Aug. 1903, Freeman & Ballard 42.

Solitary, stipitate, pear-like, becoming funnel-shaped and then 

 cupulate ; 2.5 cm. high, fleshy, fragile ; margin crenulate, incised, 

 thin, erect, or revolute ; hymenium even, bright scarlet, to i cm. 

 diameter ; exterior and stipe white and tomentose ; stipe slender, 

 tr^pering downward ; spores fusiform, acute, large, smooth, hyaline, 

 eguttulate, thick-walled, 32-40x10-14 mic; paraphyses scarce, fili- 

 form and only very slightly enlarged upward, straight, to 6 mic. 

 at apex.
