On the same piece of rock occur minute apothecia of Blastema 
ferruginea festiva (Nyl.) ?, the thallus absent. 
Caloplaca Rosei spec. nov. 
Thallus crustaceous, adnate, sordid, pale yellowish, minutely areolate, 
surrounded by a closely adnate, delicately linear-laced to almost smooth, 
fan shaped spreading, pale yellow hypothallus. Thallus with KHO 
crimson ; hypothallus with KHO pale orange, neither stained with Ca 
(Cl 0 ) 3 ; apothecia sessile, 0 5 to 1 mm wide, the flat to slightly con- 
vex disk vittelline yellow with an entire margin of a somewhat paler 
color. Epithecium granulose, rich yellow ; thecium colorless, 68 /><• to 
72 high ; paraphyses loosely coherent, furcate and septate beneath 
the subglobular pale yellow heads ; hypothecium colorless ; asci 8- 
spored, clavate, 50 to 60 /a long, 12 ft to 14 ft thick ; spores oblong- 
ellipsoid, some polari-locular with connecting tube, others having the 
cells approximate, 12 to 16 long, 4 ^ to 8 ft thick ; hymenial gela- 
tine with iodine blue ; epithecium with KHO carmine, the other 
hymenial structures a light pink, or mostly, without reaction. The 
distinctive hypothallus and chemical reactions have induced the recog- 
nition of this species as new, and it is named forks collector, Dr, J. N. 
Rose of the Smithsonian Institution. 
On quartzose rock, San Roque, Lower California, March 15th, 
1911, (Rose 928) 
Associated with it are Buellia stellulata (Tayl.) Mudd. (Rose 927), 
and a sterile Xanthoria, probably X. lychnea pigmaea (Bor.) Th. Fr. 
Dirina Catalinariae spec. nov. 
Thallus determinate, thick, areolate-rimose, white, reaction with 
KHO yellowish, with Ca (CIO Is pinkish-red, the algae are 
Apothecia 1.5 to 2 mm wide, substipitate upon a short thick thalline 
elevation ; disk round or slightly angular, dark but covered by a dense 
white pruina, proper margin thin, hidden by a turgid thalline one, 
which later becomes thinner. Epithecium granulose, sordid, pallid 
yellowish ; thecium colorless, 120 f«- to 140 fi high ; paraphyses loosely 
coherent, with fine granular interior, not well defined ; hypothecium 
thick, dark brown, on section appearing black to the unaided eye, 
its upper surface concave, the lower projecting downward with an 
acuminate central point into the medulla of the stipular elevation ; 
asci clavate, 72 p long, 16 thick, the membrane thick throughout ; 
spores fusiform, their ends rounded, straight or lightly curved, epi- 
spore distinct, 24 fi to 30 long, 6 to 8 thick ; hymenial gelatine 
gradually vinous red with lod., KHO — ; the asci are numerous, but 
spores are rare and but few are seen with spores. In place of apothecia 
many of the substipular elevations are capped by isidiose heads. 
Spermatia were not found. 
Type locality, Catalina Island on beach boulders near Avalon, 
May, 1911. Type in herb. Hasse. 
An interesting addition to the two corticular species of Southern 
California and the one saxicolar species of the northern coast.
