They are generally terete but sometimes a little flattened or com- 

 pressed. The central filaments tend to hold the spores in mass so 

 that they do not fall away as readily as in other species, and their 

 attachment to the apex of the peridium appears to interfere with its 

 rupturing at that point. Two other species, viz: Peridium Pint 

 Lev. and Peridium Harknessii Moore, have been reported as inhab- 

 itants of Pinus ponderosa. 



Dothidea Dasylirii. — Stroma amphigenous, small, narrowly el- 

 liptical, oblong or linear, black, for a long time covered by the epi- 

 dermis which is at length ruptured longitudinally; cells few, white 

 within; asci oblong or subcylindrical; spores crowded or biseriate, 

 oblong, often a little broader toward one end, colorless, .0012-.OOP7 

 of an inch long, .00065-00075 broad.

 Arizona. May. Pringle. 



Dothidea Pringlei. — Stroma irregular in shape, variable in 

 size, two to twelve lines long, penetrating the matrix deeply, am- 

 phigenous, black, surface uneven, coarsely papillose by the scattered 

 slightty prominent ostiola, cells unequal, deeply seated; asci cylin- 

 drical; spores oblong-elliptical, smooth, uniseriate, colored, .0012- 

 .0016 of an inch long, .0008 broad, often containing two or more 

 nuclei.

 May. Pringle. 



Sometimes the surface of the stroma is shining, but usually it 

 is opaque. 



Teichospora aridophila. — Perithecia minute, .01-.012 of an 

 inch in diameter, scattered, hemispherical or depressed, black, ostio- 

 lum minute, papilliform; asci subcylindrical, .0015-0018 of an inch 

 long, .0011-. 0012 broad; spores crowded or biseriate, oblong or obo- 

 vate, slightly constricted in the middle, muriform, colored, .0011- 

 .0011 of an inch long, .0005-0006 broad. 



Bleached surface of dry wood. Arizona. May. Pringle. 

 This species is closely related to T. obducens, but differs so 

 much in habit, that it seems best to separate it. 



Seleilia aurea.. — Growing with the normal form of this species, 

 having golden yellow petals, is a variety with the petals pale canary 

 yellow. 



This species has fragrant flowers. The pleasant oder is wafted 

 with the wind to a considerable distance from a large patch. 



The golden yellow of the petals is so intense that it is painful 

 to the eyes to look for any length of time at a large patch in the 

 bright sunshine. 



The flowers are so conspicuous they would make a striking ap- 

 pearance in a flower garden planted in bunches. — F. L. Harvey.
