NOTES ON THE DISCOMYCETE FLORA OF IOWA. 
BY FEED JAY SEAVEE. 
The following is a list of a number of species of Discomycetes (includ- 
ing Hysterineae) collected during the last year, which have not been 
reported in previous papers, also a few notes on other species. This paper 
is a continuation of the one published in the last volume of the Proceed- 
ings of the Iowa Academy of Science, and txie number preceding each 
description is the herbarium number of the species described. 
Sphaerosoma echinulatum Seaver was described in the Journal of 
Mycology from material collected near Iowa City in June, 19^4. In June,' 
1905, the same species was collected in Germany, issued by Dr. Rehm' 
in his As'^omycetes, No. 1601, and described in Annales Mycologici, 3: 
409. A specimen of the German material has been examined by the 
author and as stated by Dr. Rehm in his description the German speci-”" 
men corresponds almost exactly with the American except for a few slight 
differences in measurements of spores, asci, etc. The long spines on 
the outer surface of the spores which is characteristic of the species are 
common alike to the American and foreign specimens. That this species 
should occur in two such widely separated localities is interesting. 
105. Trichopeziza sulphurea (Pers.) Fckl. Plants small, about 1 mm, 
in diameter, gregarious, sessile, hemispherical, clothed externally wnth a 
dense covering of delicate hairs which are filled with yellow coloring 
matter so that the whole plant when fresh has a sulphur-yellow color, 
color fading in dried specimens; hairs variable in length, as long as 75 
mic., 8-spored; sporidia fusiform, nearly straight or curved, with several 
near their ends, blunt; hymenium concave, whitish; asci 65 to 75 by S 
mic„ 8-spored; speridia fusiform, nearly straight or curved, with several 
guttulae, 16 to 20 by 2 mic.; paraphyses 2 to 4 mic. broad at their spices. 
On dead stems of herbaceous plants. August, 1905. Mt. Pleasant, 
Iowa. Two collections were made both in the same locality. 
106. MolUsia atrata (Pers.) Fckl. Plants gregarious, at first nearly 
rounded, becoming expanded, externally black, hymenium concave, cin- 
erous, often quite dark; asci about 25 by 5 to 6 mic.; sporidia 5 to 6 by 
2 mic.; paraphyses slender. 
On dead herbaceous stems (Am'brosia trifida) August 3, 1905. Mt. 
Pleasant, Iowa. 
The plants described here under this name are larger than is usually 
indicated for this species but other characters seem to conform closely. 
107. Cihoria sulphurella (E. & E.) Plants gregarious, stipitate; stem 
variable Tn length, sometimes as much as an inch long and slender, hut 
»ftea very short; cup 2 to 5 mm. in diameter, a little concave; plants very
