other forms of the clusters and pileoli, the covering of the upper 
surface, and the spore characters there is no difference between 
those fructifications produced without woody food and those 
having it. There is no sharp color separation between these 
color extremes. 
Specimens growing on the ground usually have a short stem- 
like base, while those growing on wood are reflexed; the same col- 
lection may show both these conditions, as, for example, that 
from Skagway, Alaska, if some of the fructifications start from 
sticks and others directly from the ground. Persoon regarded 
the stem in T. terrestris as the chief character separating that 
species from his T. laciniata, as may be seen from his own de- 
scriptions contrasting the two in his ‘Synopsis Fungorum, pp. 
566 and 5067, as follows: 
“3. THEL. TERRESTRIS: subimbricata obscure fusca, pileo applanato 
fibroso-strigoso.”’ 
"Hab. in arenosis ad terram. Stipes breuis, lateralis omnino adest. 
Substantia submollis, non ita coriacea sicca, vti in ceteris speciebus." 
“4. THEL, LACINIATA: imbricata obscure fusca, pileo tenui laciniato 
crispo subtus papillis congestis scabro.” 
“Hab. ad radices truncorum. Cespitem difformem efformat, 2 упс. 
lata, tenuis. Stip. vix adest distinctus." 
These descriptions supplement each other as a description 
for one species; each has special application to fructifications 
growing side by side under such conditions as to show that they 
аге from а common mycelium. Persoon never claimed that his 
species differed from 7. terrestris in color. Fries gave a different 
description of T. laciniata in his works cited—to the injury of 
T. intybacea—, but the characters he gives are not satisfactory. 
European mycologists with a wide knowledge of the Thele- 
phoracee as they grow are unable to distinguish these two species. 
In letters to me, Bresadola regards Т. laciniata as a synonym 
of T. terrestris; and Romell does not know T. terrestris if it is 
distinct from T. laciniata.
