MYCOLOGICAL NOTES FOR 1920 169 
istic features of the species, which are the oblong-ellipsoidal to 
subglobose spores and the large conspicuously incrusted hyphae 
of the subhymenium next the substratum. These hyphae are 
4—6 vy. in diameter and possess both cross walls and clamps. The 
spores under the microscope are all but hyaline, although the 
species is included among the Leptospori by Dr. Burt, who 
states that they sometimes appear slightly yellowish. No 
cystidia are present. 
Merulius subaurantiacus Peck is recorded as a synonym by 
Dr. Burt, and my sections of the type of that species show struc- 
tures identical with those of M. fugax, except that no incrusted 
hyphae are present next the substratum. Apparently no other 
species described from America has similar spores. 
8. SOLENIA FASCICULATA (Pers.) Fr. 
Plants rather crowded on eigen wood, Spoppen 
of isolated cylinders not more 
thick, whitish or slightly mens externally compactly tomen- 
tose; hymenium lining the hollow ae of clavate basidia 
without cystidia; spores not seen attached to basidia but free 
floating, hyaline, thin-walled, and 5-7 wu in diameter. 
On coniferous wood. Reitz Gap, ee County, Pennsyl- 
vania, September 20, 1920, J. F. 
According to C. G. Lloyd, who pete the determination, 
S. villosa Fr. is probably the same species. These specimens 
depart from the available descriptions of S. fasciculata, which 
call for a plant 2-7 mm. high. The plants under the hand lens 
(PLATE 9, FIG. 3), resemble a simple Mucronella in which genus, 
however, the basidia are external. 
g. POLYPORUS CAERULOPORUS Peck 
Collected on the banks of Stone Creek, Huntingdon County, 
Pennsylvania, July 9, 1920. 
A rare species, listed by Murrill as occurring in New England 
and New York. The uniform pale indigv-blue color of cap, 
tubes, and stem is unique among the pore fungi. A single
