4. TULASNELLA VIOLAE (Quél.) Boud. & Gal. 
The genus Tuwlasnella, recently monographed for this 
country by Burt, is an anomalous genus, Corticiwm-like in 
appearance, but hardly so in structure. It is characterized by 
the presence of large sterigmate-like processes, four in number 
(usually), that are produced on a basidium-like organ, and that 
in turn bear each a hyaline spore. Only three species are list- 
ed by Burt, all of narrow geographical range and none hitherto 
reported from Pennsylvania. 
Asmall collection of T. Violae was made in the mountains of 
Center County, Pennsylvania, on January 29, 1921, on the inside 
of a gum (Nyssa sylvatica) log by the writer’s mycology class while 
on a collecting trip. The discovery of the specimens is credited 
to Mr. Kuntz 
The color of these specimens was flesh pink or livid pink 
(Ridgway) when collected, but it is not probable that they will 
long retain these colors in the herbarium. In aspect the plants 
resemble very much a thin species of Corticium, and casual ob- 
servations of free hand sections show nothing very different 
from sections of species of that genus. Spores were abundant 
in the collection, however, and it was only when the usual 
attempt was made to substantiate their connections to basidia 
that the real nature of the hymenium became apparent. With 
some difficulty the large clavate or elongate sterigmata were 
made out, sometimes four in number and sometimes apparently 
but three. After the development of the sterigmata the basidia 
appear to collapse, or at least in a spore-bearing condition the 
group of sterigmata is so large as to give this impression. The 
spores are broadly ellipsoid to globose, and in these specimens 
have two or three large conspicuous guttulae The spores 
measure 5.5-7.5 X 5 u. No cystidia are present. 
5. DACRYOMYCES HYALINA Quél. 
The species of the genus Dacryomyces are not well known in 
this country, partly because, in spite of their usually bright 
colors, they dry down and are rather inconspicuous in dry 
weather, when collectors are most likely to be in the field. D. 
hyalina, as determined for me by C. G. Lloyd in 1919, was
