Excluded Genera and Species 



Cudoniella fructigena Rostrup. Med. Gr0nl. 3: 605. I89L According to 

 Durand this belongs with the Helotiaceae. He states further that he believes 

 the genus Cudoniella to be ill founded since the species thus far referred to it 

 might better be placed elsewhere. 



Helotium aciculare (Bull.) Pers. Syn. Fung. 677. 1801 ; Helvella acicularis 

 Bull. Hist. Champ. Fr. 296. 1791; Peziza acicularis Fries, Syst. Myc. 2: 156. 

 1822; Cudoniella acicularis Schrot. in E. & P. Nat. Pfl. P: 166. 1897. 



Roesleria hypogaea Thiim. & Pass. Durand states: "I have seen this species 

 growing on buried grape canes in New York and Missouri. Schroter placed 

 it in the Geoglossaceae, while Rehm and others regard it as synonymous with 

 Coniocybe pallida (Pers.) Korb., and refer it to the Calicieae. Judging from 

 the specimens seen its affinities do not seem to be at all close to the Geoglos- 

 saceae, so that I exclude it from that family." 



Family 4. HELOTIACEAE 



Apothecia extremely- variable, ranging in size from a fraction 

 of a millimeter to 2 or 3 centimeters in diameter, sessile to long-

 rarely erumpent on herbaceous stems, colors varying from white, 

 bright-yellow, or red to green, olive, blue, brown, or nearly 

 black, smooth, or hairy; asci cylindric to broad-clavate; spores 

 simple or compound, globose to long-filiform, hyaline or more 

 rarely colored; paraphyses hyaline or more rarely colored, fili- 

 form, or rarely with lanceolate, pyriform, or subglobose ends. 



Apothecia not distinctly hairy. 



Apothecia arising from a sclerotium or scle- 



rotium-like substratum.
