Mycological Notes and new Species 
By C. L. SHEAR 
FusIcLADIUM FASCICULATUM C. & E. Grevillea,.6: 88. Mr. 1878 
A careful study and comparison of authentic specimens of 
this species, issued by Ellis in North American Fungi no. 545, 
with Scolecotrichum euphorbiae Tracy & Earle, Bull. Torrey Club, 
23: 209. May 1896, as represented in the herbarium of the De- 
partment of Agriculture by specimens marked “ type material” 
and sent by Tracy and Earle shows that they are the same species. 
Both are on stems and leaves of Euphorbia. The form on stems, 
NOA. Fi s45, appears more effuse than that on leaves, Fungi Col. 
380, which is identical with the Tracy & Earle material. The 
conidia vary considerably in size. The effuse form, N. A. F. 545, 
has conidia 9-16 x 5-7 2. Tracy & Earle’s specimen has some- 
what larger conidia, varying from 13-22 x 6~—8 4. As pointed out 
by Tracy & Earle this is not a typical Scolecotrichum in the sense in 
which the genus is defined by Saccardo. What the typical Sco/e- 
cotrichum of Kunze & Schmit, Myc. Heft 1: pl. 7. f. 5. 1817, is 
does not, however, seem very clear. It is amonotypic genus, the 
authors having referred to it only one species, S. virescens, which 
is rather indefinitely described and poorly figured. Unless speci- 
Mens of the type are extant it is doubtful whether the genus can 
stand. 
The plant under discussion belongs however, to the group to 
which this generic name is at present applied rather, than to Fusi- 
cladium and unless there is an older tenable name should be des- 
- nated Scolecotrichum fasciculatum (C. & E.). 
Lacunum Encetmanni Tracy & Earle, Pl. Bak. 11: 25. 1901 
An examination of this species as represented by type material 
(No. 1058 Baker, Earle & Tracy on Picea Engelmannt, La Plata 
Mts., Colo.) seems to indicate that it is identical with /eziza 
(Dasyschyphae) arida Phill. Grevillea, 5: 117. pl. 89.f. 73. 1877. 
We have had no opportunity to examine type material of 
Phillips’ species, which was collected by Harkness & Moore on 
449
