BURT — THELEPHORACEAE OF NORTH AMERICA. V 743 



and with basidia and spores at base of the paraphyses ; basidia 

 longitudinally septate ; 11 X 7 n ; spores colorless, even, 7%- 



9 X 5-6 ix. 



Fructifications about 2 cm. long, about 2 mm. thick. 



In cane field. Porto Rico. 



T. simplex is noteworthy by the column composed of longi- 

 tudinally arranged, black hyphae, which extends the whole 

 length of fructification and constitutes the whole, upper, 

 sterile two-thirds of the fructification and is clothed by the 

 ochraceous hymenium on the lower third. The specimens are 

 broken off at the base, hence I cannot be sure that a stem was 

 not originally present, but if present it would doubtless have 

 been included in the packet. The general habit is that of a 

 small Geoglossum or cylindric Xylaria.

EICHLERIELLA 



Eichleriella Bresadola, Ann. Myc. 1 :115. 1903. — Hirneolina 

 as a section of Sebacina Patouillard, Essai Taxon. 24. 1900. 

 Hirneolina (Pat.) Saccardo, Syll. Fung. 17:208. 1905. 



Fructifications coriaceous, waxy or membranaceous, sub- 

 gelatinous, cup-shaped or plano-concave, rarely pendulous, 

 hymenium typically superior, discoid, inferior in pendulous 

 forms, even or somewhat rugulose; basidia globose-ovoid, 

 cruciately divided, with 2-4 sterigmata; spores hyaline, 

 cylindric, somewhat curved. It is a Stereum or Cyphella with 

 tremellaceous hymenium. 



The type species of the genus is Eichleriella incarnata Bres. 



The original definition of Eichleriella, which is translated 

 above, should be broadened to accurately describe our North 

 American species, which are as coriaceous as Stereum 

 spadiceum. All have the hymenium inferior. Eichleriella 

 gelatinosa is our only species with subgelatinous hymenium. 



But few species of this genus are known. Five species of 

 Eichleriella have been recognized up to the present time in 

 North America, three in Europe, and two in South America ;
