 262 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



48. 1892, but not Bonia Balansa). — Grandinioides Banker,

Thelephoraceous fungi having the hymenium bristling with 

 short cylindric fascicles of hyaline hyphae which arise from the 

 subhymenial tissue. 



The type species is Mycohonia flava. 



Patouillard intended at first that this genus should include 

 both resupinate and pileate species, but he soon transferred the 

 known resupinate species to Heterochaete on account of the 

 longitudinally septate basidia. A few years later he introduced 

 Epiihele in connection with resupinate species, having hyphal 

 fascicles like those of Mycohonia fiava.

Fructification coriaceous, convex, somewhat orbicular to reni- 

 form, sessile, attached by a point on one side, even, glabrous, 

 drying ochraceous buff to cinnamon; hymenium ochraceous 

 buff, with numerous short hyphal fascicles suggesting the
