Faniii\ 3. Geoglossaceae. 



Order PEZIZALES (conlinucd) 

 (For diagnosis see North American ("up-fungi. Operculates) 



Asci inoperculate (opening by a simple pore at 

 the apex). 

 Ascophores stipitate, clavate, spathulate, 

 or piieate, rarely discoid or turbinate, 

 on the ground or more rareh' on plant 

 tissues. 

 Ascophores typically cup-shaped or dis- 

 coid, not as above, usualh' on living 

 or dead plant tissues, never or rarely 

 on the ground. 

 Apothecia for the most part soft and 

 fleshy or wax}', superficial from the 

 first, or erumpent on herbaceous 

 plant tissues. 

 Apothecia soft or more often hard, 

 leather} , or horny, erumpent through 

 the substratum, often cespitose, usu-

 plant tissues. Famil\ 5. Cenangiacear. 



Famih' 4. Helotiaceae. 



Family 3. GEOGLOSSACEAE 



Ascophores mostly club-shaped, or clavate, more rarely dis- 

 coid or turbinate, the hymenium arising directly from the surface 

 of the clavula and forming a uniform stratum over it, usually 

 covering only a part of the ascophore but in some cases extend- 

 ing over the whole of it, or piieate, the hymenium occupying the 

 upper surface only; consistency fleshy but usually elastic or 

 fibrous rather than brittle, a few leathery, others distinctly 

 gelatinous; asci usualh" 8-spored; spores varying from ellipsoid 

 to fusiform, h\aline, or colored. 



Ascophore stipitate, clavate, or spathulate, the as- 

 cigerous portion usualh' more or less compressed, 

 rareh' subglobose. 

 ("lavate, the ascigerous portion not or only slightly 

 decurrent on opposite sides of the stem. 

 Spores small, ellipsoid, cylindric, or fusiform,
