EXIDIA . GLANDULOSA FROM DR. JAMES R. WEIR, IDEHO (Fig. 1932 ).- 
The common Exidia glandulosa takes two different forms or species I 
think, but they are not separated in our books. The widely distri¬ 
buted plant, the one we have in America and the plant I found in 
Sweden, is not the same consistency at least, as the plant around 
Paris that Bulliard figured. But the name is taken from Bulliard, 
hence if we hold them as different we would have to invent a name 
for the common form. We might continue to call the common plant as 
generally called, Exidia glandulosa, and the local form around Paris, 
Exidia. arborea as named by Hoffman, but if one did that Otto Kuntxe 
would turn over in his grave and the Kuntzeites would have a. spasm. 
Or we might take the view of the Brussels conspirators and call the 
common plant Exidia.glandulosa on the ground that Fries did not know 
any better and what Fries did not know no one has any business learn¬ 
ing. Neither view is satisfactory to me, so I shall continue to call 
them both Exidia glandulosa merely designating the one I found around 
Paris as the Parisian form, and labeling it Exidia arborea in the 
collection and on our figures. 
Exidia glandulosa begins as erumpent tubercles attached to 
the host by appoint but it soon becomes confluent and cerebriform and 
resembles a Trdmella, Our figure 1930 well represents it in the 
usual form. The color is dark brown, almost black one might say, and 
the surface is covered with little projecting papillae. These 
papillae are multicellular, about 50 X 100 mic. and are on the surfac 
as shorn in Tulasne 1 s figure, not imbedded in the tissue as some¬ 
times inaccurately figured. The basidia are ovoid, 15 X 20 when 
young, brown becoming paler when old. Spores 4 X 16, hyaline, 
cylindrical, curved. 
The usual form (Fig. 1'930 ) is very common everywhere and 
favors beech willow and alder. In very wet weather it absorbs mois¬ 
ture and becomes so soft that it "runs". It dries to a thin, black 
film and the dried specimen (Fif. 1931) hardly suggests the soaked 
plant. Mr. Weir finds on willow in the West a.form with much larger 
lobes and fewer papillae (Fig. 1932). We show in the figure the 
under surface also, showing the small point by which it is attached. 
EXIDIA GLANDULOSA (PARISIAN) (Fig. 1933).- I collected 
around; Paris and have seen it from no where else a form of Exidia 
glandulosa., which was the original of Bulliard and of Tulasne as 
shown in their figures and preserved in Tulasne's herbarium. This is 
much more firm and discoid (Fig. 1S33 ) than the usual plant and re¬ 
tains its shape when dried (Fig. 1934). In fact it is for me closer 
to Exidia.truncata than it is to Exidia glandulosa, but it is the 
original of Exidia. glandulosa, and of course as Fries did not know 
it, it can not be changed now. That is the "law". I have however, 
labeled it in my herbarium, and the figures, Exidia arborea. 
CLAVARIA LACINIATA FROM H. C. BEARDSLEE, CANADA (Fig. 1935) 
as illustrated by Schaeffer. Perhaps a form of Clavaria.. rugosa, but 
much more branched than the type figure of Bulliard. Or it mignt be 
held as a. form of Clavaria cristata, with the branches all above. 
Spores globose, 8-10 mic., smooth. We present a figure 1935 from 
photograph from Professor Beardslee, We have this same plant from 
Overholts, and Fig. 1936 is made from his photograph. We referred 
it when received to Krombholtzii.
