THELEPHORA 
Thelephora Ehrhart [Crypt. Exsic. No. 178. 1785) Fries, 
Syst. Мус. 1: 428. 1821 (in part).-Persoon, Myc. Eur. 1: 
110. 1822 (in part).-Saecardo, Syll. Fung. 6: 521. 1888 (in

The type species of the genus is Thelephora terrestris Ehrh. 
ex Fries. 
Fructifieations pileate or clavate, coriaceous; hymenium con- 
tinuous with the hymenophore and similar to it, inferior, or 
amphigenous in a few species, even or faintly ribbed or papillose; 
basidia simple, 4-spored; spores colored, typically muricate but 
even, or rough-walled in a few species. 
As more broadly defined by Fries and the other authors cited, 
Thelephora has been heterogeneous, consisting chiefly of the 
natural and homogeneous group of species defined above but 
also of some pileate species with simple basidia and hyaline 
spores, transferred to Stereum; also of some species with globose, 
longitudinally septate basidia, transferred to Tremellodendron, 
if with erect fructifications, or to Sebacina, if resupinate; and 
also of some resupinate species having simple basidia, of which 
those with muricate and colored spores may be found in Hypoch- 
nus, those with colored and even spores, in Coniophora, and 
those with hyaline spores, in Corticium and Peniophora. It is 
probable that the species of Patouillard’s section Dendrocladium 
of the genus Lachnocladium as understood by Patouillard ! 
might be transferred to Thelephora with advantage both to 
Thelephora and Lachnocladium, but these species are not within 
the geographical limits of my work.
