78 HARPER: TWO REMARKABLE DISCOMYCETES 
hymenium and in dried plants the hymenium becomes reddish 
brown where the asci are numerous, while the stem remains 
whitish. The base of the plant is rounded like the base of species 
of Morchella. No thick mycelial root or sclerotium of any kind 
was found. 
Sometimes the clubs are simple as shown on PLATE 2 and’ in 
Peck’s illustration but they usually divide into fingers. The 
plant on PLATE 1 was divided near the middle. The halves 
have split and sprung apart as shown in B. The left branch 
shown at A is forked near the apex.’ The right branch was nearly 
destroyed by insects but appeared to have been more deeply 
divided. Other plants in the collections were divided a little 
below the middle. PLATE 2 shows two plants, one of which has 
been sectioned, closely caespitose and apparently connected at 
the base. In the cluster of small plants first discovered there were 
at least three connected at the base. 
The whole interior of the plant—bulbous base, stem and as-. 
coma—is perforated by irregular longitudinal cavities, as shown in 
the section on PLATE 2,A. The walls of the cavities are of nearly 
uniform thickness. The interior of the walls is composed of a 
mesh of septate hyphae 6—-8u in diameter. The cavities are lined 
with a palisade layer of regular, septate hyphae about 6y in diam- 
eter. The layer is about 50u thick and there are three or four 
septa in each hypha. The appearance of a cross section of one 
of the walls is like that shown in Hesse’s Hypogaeen Deutsch- 
lands, pl. 18, f. 12 (1894), except that the interior is composed 
entirely of septate hyphae. | 
The outside walls are covered with the hymenium on the outside 
and the palisade layer on the inside. The surface of the hymenium 
is wrinkled and corrugated, PLATE 2, C, but there appears to be no 
definite relation in position between the wrinkles of the hymenium 
and the internal cavities. The interior of the walls is composed 
of hyphae, and there appears to be no definite subhymenial layer. 
A palisade layer like that on the walls of the interior cavities 
covers the stem and base of the plant. 
easci, PLATE 2, B, are club-shaped, 10-12 X 160-200n. They 
open by a lid as far as I can make out but I have not been able to 
find empty asci, which Boudier says must be examined to deter-
