STUDIES ON THE TREMELLINEAE OF WISCONSIN. 
E. M. Gilbert. 
The Tremellineae have so far been little studied in any of the 
Mississippi Valley States. In the following list I have brought 
together the material collected by myself and others in Wiscon¬ 
sin as a preliminary contribution to our knowledge of the species 
of this region. The list is of course far from complete and 
without a doubt many additions to it may be expected in the 
near future. The identification of the species is especially diffi¬ 
cult, but it is a necessary preliminary to a further physiological 
and cytological study of the group. The classification used is 
based upon that of Eries as somewhat rearranged by Winter. 
Fries’s technical description of the group is as follows: “En¬ 
tire fungus homogenous, gelatinous, collapsing when dry, re¬ 
gaining its form when moistened, traversed internally by 
branched hyphae which terminate in basidia at the periphery; 
basidia variable in form, elongate or fusoid; transversely septate 
or continuous, undivided or with the apex forked, or sub-globose 
and cruciately divided and bearing two or four sterigmata; 
spores hyaline, globose, ovoid or kidney shaped, continuous or 
septate, often becoming variously septate on germination and 
producing sporidiola (conidia) of various forms. 
The basidia which of course are the characteristic feature of 
the group, are, as is well known, of several quite distinct types. 
In Auricularia, the basidia are essentially like the promy¬ 
celium of a rust. They are transversely septate, each cell 
producing near or at its apex a single sterigma. A second type 
occurs in Dacrymces and Guepinia where the basidium is more
