eupulate pileus here and there lacunose-pervious, and the inner 
are distinct, erowded, erect, narrow; hymenium inferior, uneven, 
whitish ; basidia simple; spores slightly colored, becoming uneven, 
ovoid, 5-6 x 4-5 y. 
On the ground. Costa Rica and Brazil. January. 
“Тп substance, texture, color, etc., this species agrees exactly 
with Thel. cornucopioides and Thel. angustata but in form it ex- 
hibits a type unique in the Hymenomycetes. The clusters are 
regularly rounded, very dense, divided all the way to the base 
into innumerable lobes, of which the interior are free and erect, 
the exterior regularly ascendant, broader, compressed, clothed 
underneath by the hymenium and grown together into a cup 
here and there lacunose-pervious, undulate-crisped at the apex 
and fimbriate."—' Translation of the original comment on this 
species. 
In 1899, I found the type in Herb. Fries to be cinereo-pallid 
with a slight fuscous tinge and with basidia and spores as stated 
above but many of the spores even. Romell describes the spores 
of his specimens from Brazil as “hyaline, laeves, ellips., 5-7 
x 3-4 mmm.,” and as agreeing with the type. I have reéxam- 
ined my sections from the type; the spores are certainly colored 
and many of them rough-walled. 
Specimens examined: 
Costa Rica: San José, Oersted (in Herb. Fries, Univ. Upsal.),

Type: not known to be in existence; not in Herb. Fries, at 
Upsala, nor in Kew Herb. 
Pileus pliant becoming rigid, deeply infundibuliform, 5-71 
cm. broad, radiately rugose, glabrous, fuscous; stem solid, 
rather glabrous, pallid; hymenium inferior, somewhat rugose, 
gray. 
On the ground. Near San José, Costa Rica. 
This species bears so singular a resemblance to Craterellus 
cornucopioides that from pictures they are scarcely to be dis- 
tinguished. The present species has the stem truly solid and 
the substance fleshy pliant when living, nearly stony-woody 
when dry; stem 5-73 cm. long, 4-6 mm. thick, equal or attenu-
