ASGOMYCETES AND LOWER FUNGI. 



GUY WEST WILSON AND FRED. JAY SEAVER. 



It is the intention of the writers to issue, as material accu- 

 miulates, exsiccati of fungi under the above title, the scope of 

 the work being limited to Ascomycetes, Deuteromycetes and 

 Phycomycetes. This material will be issued in unbound fasci- 

 cles of twenty-five numbers each. The following is an annotated 

 list of the contents of the first fascicle : 



1. Chlorosplenium chlora (Schw.) Massee. 



Pesi.za chlora Schweinitz, Syn. Fung. Car. Sup., 



96. 1822. 

 Chlorosplenium schzveinitzii Fries, Summa Veg. 



Scand., 356. 1849. 

 Chlorosplenium chlora (Schw.) Massee, Jour. Linn. 



Soc, 35:116. 1901. 



Plants externally bright yellow ; hymenium dull becoming 

 green. The genus Chlorosplenium was founded by Fries on C. 

 schweinitzii which is synonymous with this species. 



2, Dermatea olivascens Rehm, Ascomycetes, 1686. 



The material issued under this number is a part of the type 

 collection. The species is close to Dermatea crataegicola Durand. 

 On branches of Crataegus sp. apparently dead but still on the 

 tree.
