7. PARMELIA MOLLIUSCULA, 
BY HENRY WILLEY. 
In the report issued May 28, 1892,* Mr. T. A. Williams 
described and figured a fruiting specimen of Parmelia mol- 
“iuscula from the Black Hills region. I have in my posses- 
sion a specimen, or rather a fragment of one, collected by 
Mr. Brandegee on Soda Springs Lodge, Colorado, alt. 
5,500 feet, in 1877, which is fertile, and which, so far as 
it goes, resembles the figure given by Mr. Williams. It 
presents a number of apothecia, crowded together, with a 
brown and at length blackening disk, and an incurved, more 
or less crenate margin. «The spores are ellipsoid, measuring 
.011-.013 mm. long by .005-.006 mm. broad, thus agreeing 
well with the imperfect spores seen by Mr. Williams. The 
spermatia are staff-shaped, .007-.009 mm. long. 
Dr. Nylander, to whom I sent a bit, suggested that it 
might be P. subconspersa, Nyl.; but the reaction with 
potash,— medulla blood red,— agrees with that given for 
P. molliuscula, and not with that of P. subconspersa, and 
I know of no better place for my fragment than with the 
former. It would be interesting to obtain further fertile 
specimens of this lichen, which was unknown in fruit 
before Mr. Williams’ observation.
