under the same name in Fung. Gall. No. 1090 only Stachybotrys 
lobulata could be obtained. Тһе specimen under the name 
Ch. Fieberi Cda. in Herb. Myc. No. 165 and Myc. Ital. No. 1288 
is in part Ch. globosum Kze., and in part Ch. elatum Kze. Only 
Ch. murorum Cda. could be obtained from mounts of Ch. Kunse- 
anum Zopf, in Fung. Gall. No. 4436, while the specimens under 
the name CZ. lanosum Peck, in Fung. Gall. No. 4437 consist for 
the most part of Chaetomidium fimeti (Fckl.) Zopf, with a con- 
siderable number of perithecia of Ch. elatum Kze. intermingled. 
Ch. olivaceum C. & E. in Fung. Columb. No. 512 is found to 
consist partly of Ch. globosum Kze., of Ch. elatum Kze., and in 
part of Chaetomidium fimeti (Fckl.) Zopf.
