BURT—WOOD-DESTROYING FUNGI OF JAVA 41 
Protomerulius javensis Burt, n. sp. Plate 2, fig. 4. 
Type: in Mo. Bot. Gard. Herb. 
Fructifications resupinate, effused in elongated patches, 
coriaceous, separable when moist, drying tawny olive of Ridgway, 
and showing under the microscope an imperfectly porose surface 
with thin irregular folds and dissepiments somewhat lacerate; 
pores angular, sinuose, shallow, about 60 y deep, about 10 to a 
mm., sometimes elongated laterally and divided by cross parti- 
tions into smaller, equal, angular pits or pores; in structure about 
400 u thick, composed of densely interwoven, slightly colored, 
non-incrusted, thick-walled hyphae 2 y in diameter; basidia 
pyriform, longitudinally cruciately septate, 12-18 х 6-7 ш; spores 
simple, hyaline, even, curved, 15 X 4 u, but few found. 
Fructifications up to 5 em. long, 2-3 cm. wide, about 1% mm. 
thick. 
On dead, rotten limbs of Castanea argentea, 5000 ft. altitude, 
West Java, C. Hariley, type (in Mo. Bot. Gard. Herb., 59516). 
Other species of Protomerulius are P. brasiliensis A. Moller 
and P. Farlowii Burt—the first from Brazil and the second 
from New Hampshire. The occurrence of these 3 species at such 
great distances apart is remarkable. 
A mycelium causing a locally destructive root-rot of teak was 
also received, but I could detect no fructifications by which it 
might be identified. 
On roots of teak, Tectonia grandis, East Java, C. Hartley (in 
Mo. Bot. Gard. Herb., 59521).
