172 ; MYCOLOGICAL NOTES FOR 1920 
of the parasite. They are not produced in chains but formed 
singly as the termini of small hyphae deeply staining with eosin. 
This fungus has been under careful observation for sev- 
eral years, but only the chlamydospore condition was known 
until 1920. A well-developed pileus is never present. In some 
respects the species shows resemblance to P. Ellisianus Murrill, 
which however is found on coniferous wood and has entirely 
different spores. The cushion-shaped or nodular type of sporo- 
phore, bearing only the chlamydospore condition, has the context 
more or less zoned and with a disagreeable odor as of strong lard. 
11. Fomes BAKERI Murrill 
I found this species to be quite common, by far the most 
common species of Fomes, in the vicinity of Kingston, New Jersey, 
where I observed it in company with Mr. E. West in August, 1920. 
Its only host in that locality is the river birch, Betula nigra, 
which is its host also in the Mississippi Valley. The species 
was described and illustrated in my notes for 1919, where 
reference was made to a collection said to have been taken from 
Betula lutea near Philadelphia in 1915 by Rhoads. In all prob- 
ability the host for this collection was B. nigra, as B. lutea is 
not found in that locality, according to Dr. Rhoads. 
In connection with this species it was of interest to find 
recently in the Schweinitz Herbarium at Philadelphia a specimen 
of Fomes under the name of Polyporus annosus Fr. (Syn. N. Am. 
Fungi No. 401) that is undoubtedly F. Bakeri, although it seems 
not to have been recognized by those who have worked over 
the Schweinitzian material in recent years. Lloyd once referred 
this specimen to F. rimosus, noting, however, its similarity to 
F. robustus Karst., which he has subsequently regarded as identical 
with F. Bakeri. This Schweinitzian collection bears no date but 
was made certainly prior to 1831 and was listed by Schweinitz 
as occurring on Betula. 
12. PHALLOGASTER SACCATUS Morgan 
A rare plant, placed in the Phallaceae by some largely on the 
foetid nature of the internal deliquescent gleba, but in appearance 
more allied to the Lycoperdaceae. Two specimens were collect- 
ed at Westport, Pennsylvania, August 11, 1920. Excellent 
illustrations, by which the plant may readily be known, have 
been published by Lloyd.
