r_~uth.Cortex of the nature of a sand case where it forms a persistent 
collar, separates, leaving the peridium smooth. Stem thick, pale 
slightly scaly, tapering to the base. Capillitium hyaline with 
swollen sepra. Spores 5-6 mic., almost smooth. The work we do with 
fungi constantly presents paradoxical situations. We had just finish¬ 
ed considering a TyTostoma from Geo. L. Moxlev, California, and 
explaining why we would reduce the species of Tylostoma, and th< 
package 'we open from Philip A. Munz, California, causes to explain 
why we have to increase them. Tjricstcma Mohavei was collected by 
Mr. Munz in the sands of the Mohave Desert. It is described in al¬ 
most the same words as Tylostoma McAlpinianum from Australia excepting 
size, and size does not count for much in puff balls. And yet to my 
mind they are entirely different species, different in habits and 
appearance, as we believe our figure will shew. The one on the left 
being Tylostoma Mohavei, that on the right, Tylostoma McAlpinianum. 
TYLOSTOMA MONTANUM FROM GEO. L. MOXLEY, CALIFORNIA (Fig, 
1778).- As named by Patcuillard from Tunis, if one wants a separate 
name for it, but for me it is only an obese form of Tylostoma squamo¬ 
sum as named by Persoon from Europe a hundred years ago. It was col¬ 
lected in the San Gabriel mountains by Mr. J. A. Perkins and this was 
the first time this obese form was found in the States. Wien I wrote 
my pamphlet on Tylostoma (1906) I had narrow views of species and 
recognized five 
in Groups 2 and 3 with scaly 
seems. 
If I were revis- 
.f the lot and that one 
the old. species of Persoon of Europe, where it is as rare as it is 
ing them now I should probably make one cut or 
with us. At the time 1 wrote the pamphlet an Italian had just come 
out with a paper claiming that species of Tylostoma. could be differen¬ 
tiated by 
stree 
pore and capillitium characters. I did not place much 
on it then and I do net place any on it now. For instance, 
thought our rare American species, Tylostoma verruccsum, could be dis¬ 
tinguished from the rare European Tylostoma squamosum by the persist¬ 
ent cortex and not swollen septa. But as to cortex I suspect it is 
only a condition of age and. as to septa, in examining Mr. Perkin's 
specimen (where the septa axe rare) I found two. One was exactly even 
and the other was strongly swollen. In "puff balls" as all other 
fungi the more specimens we receive the fewer the "species" we have. 
Since the above was written we have an additional specimen 
collected by 0. M, Ole: 
n 
at Los Angel 
23, California. 
XYLARIA LCJTEOSTROMATA (Fig, 1779 ).- Wien we published this 
(Myc. Notes page 893, fig,1572 ) we based it on a globose collection 
from the Philippines (Elmer 7217) which we illustrated. There was 
another collection sent us of entirely different shape, slender, club 
form (Merrill 10549) which we stated was probably the same species. 
At New York we found these same collections embracing both shapes and 
we are now convinced that Xylaria luteostromata takes both globose and 
club snapes. It develops that shape has not much to do with Xylaria 
species, 
Xylaria luteostromata is characterized by its yellow stroma, 
otherwise unknown to me in a Xylaria and its small spores, 4-5 X 8 X 9 
It is close to Xylaria oastorea and belongs to the same group 
(Polymerpha ) with solid stroma, and ncn-mcriferm surface.
