The further development of Cucurbitaria platani was not followed 
out. Secondary pycnidia began to develop on the slide in extraor¬ 
dinarily large numbers. The mycelium gradually became transformed 
into a stroma, the hyphrn continually growing darker, more closely 
interwoven and smaller celled. A stroma of this kind was placed with 
the pycnidia upon a fresh Platanus branch upon a place where the 
bark was injured. The stroma soon became completely covered with 
pycnidia. The peripheral hyphse penetrated the bark, from which 
only a few pycnidia followed. After a long time perithecia could also 
be seen; but they were so few that any investigations were not to be 
thought of. 
The ascospores of Cucurbitaria platani were sown upon another 
branch. It remained intact for a long time, but after it was apparently 
dead and had begun to decay pycnidia broke out upon the cut surfaces 
and leaf scars, in short, wherever the bark was injured. It may be 
concluded from this that Cucurbitaria platani is not a parasite but 
merely a saprophyte. Cultures upon leaves gave no reliable results.

(Plate XIV.) 
1. Tremella. tremelloides, (Berk.) Mass. (Fig. 1). Tremelloid; 
lobes fasciculate, elongated , suberect , almost free to the base or variously 
united, compressed , springing from a small contracted base, surface 
scabrid , dull orange; spores elliptic-oblong with a minute oblique api- 
culus at the base, 11-12 by 5 p. 
tSparassis tremelloides , Berk., Grev. Vol. II, p. 6; Sacc. Syll., Vol. 
No. 7926. 
On wood, Lower Carolina. (Type in Herb. Berk., Kew, No. 4088). 
Forming large tremelloid tufts, always springing from a very small 
basal portion, which penetrates the matrix; lobes suberect, 3-4 inches 
high in well grown specimens, sometimes smaller, in some specimens 
variously plicate and almost free to the base; in others the lobes are 
united laterally and form a gyrose tuft, always much compressed. 
The distinctly scabrid surface is very characteristic, and is due to 
thickly scattered papillae, which give a very harsh feel to dry specimens. 
Basidia large, sterigmata developed in succession. 
STELLA, Mass. (nov. gen.). 
(Fig. 2.) 
Peridium consisting of two distinct layers united at the base only; 
outer layer thick, splitting in a stellate manner from the apex, inner 
layer thin, indehiscent; gleba traversed by numerous anastomosing 
thin trainal plates, which are continuous with the inner wall; columella 
and capillitium absent; spores forming a powdery mass at maturity.
