Mycologia 



This last collection was made in 1891, but Ellis makes no refer- 

 ence to it in North American Pyrenomycetes or in subsequent 

 papers. In this material the stromata are broader than in the 

 Suksdorf collection and the Jjerithecia of a single cluster are 

 consequently more numerous. The cespitose habit is present in 

 both cases though in the Suksdorf material a single perithecium 

 may sometimes occur alone on a small stroma. It is probable 

 that the Suksdorf material is somewhat younger, especially since 

 the ascospores are slightly smaller and lighter colored. In the 

 material distributed by Ravenel the perithecia seem somewhat 

 more slender than in the Suksdorf collection. The relatively 

 small number of collections of material available for study 

 renders these minor differences especially noticeable and in the 

 present state of our knowledge there seems to be no better 

 course than to incorporate the known material under the one 

 species. 



The species differs from C. subcorticalis especially in its 

 stouter, more rigid perithecia and in its larger ascospores. 



Ellis obtained the specific name for this species from the older 

 binomial, Sporocybe calicioides Fries (13) which he cites as a 

 synonym. The description published by Fries is, however, 

 clearly based on a hyphomycetous fungus, and there seems to be 

 no reason for assuming the two fungi to be the same. The 

 original material of Fries is, according to Juel, not now present 

 in the herbarium at Upsala, and has probably been lost. Since 

 Ravenel 2 distributed material of the fungus of Ellis under the 

 name Sporocybe calicioides Fries, this name is cited in the syn- 

 onomy above with an interrogation mark. 



Material Examined 



Ravenel's Fungi Caroliniani 1 : 83 (specimen in herbarium 

 Harvard Univ.) ; specimen collected by Suksdorf (No. 256) in 

 Washington territory and sent to Ellis by C. G. Sprague, Dec, 

 1883. (Ellis Herb. N. Y. Bot. Gard.) ; specimen in Ellis' her- 

 barium labeled in his handwriting Hypsotheca calicioides (Fr.) 

 var. caespitosa n. var. (No. 71, March, 1891, on decaying poplar 

 log).
