Hypoxylon Malleolus was named from Carolina by Berkeley and 
specimens were distributed both in Ellis' and Ravenel's exsiccatae. 
It is a large Hypoxylon and the carbonous stroma is sub-zonate, hence 
has been called Daldinia. The surface is very characteristically 
marked with little, circular depressions around the papillate ostiole, 
as shown in Pig* 1591. enlarged. The spores as we measured them 
are 6 X 20. The species is southern only and we have specimens from 
Florida from N. L. T. Nelson and of our own collecting* In Fig. 
1550 the conidial state, from Mr. Baker, is on the left, the ripe 
specimens on the right. Fig. 1591, surface of mature plant enlarged, 
shows the very characteristic os tides. 
HYPOXYLON THOUARSIANUH• This is the same as Ellis named from 
California, Hypoxylon occidental©. It was named by Leveille from 
Galapagos as Daldinia Thouarsiana but it was never a Daldinia. I 
have always thought it the same as Hypoxylon Malleolus, but on com¬ 
parison I now think they are different but they are very close. Hy¬ 
poxylon Thouarsianum has paler stroma and more prominent perithecia. 
The general nature and size of the plants, spores (5 X 16-20) and 
peculiar depressions around the ostioles are the same. Our enlarge¬ 
ment of the surface (Fig. 1592) will show the most prominent differ¬ 
ence, in contrast with Fig. 1591. 
Specimen from S. C. Edwards, California, which we referred 
to Hypoxylon Malleolus should have been referred to Hypoxylon 
T ho uar s i anum. 
AURICULARIA DISCENSA FROM REV. J. RICK, BRAZIL (Fig.1593).- 
Since it has become the fashion to base a genus of tremellaceous 
plants on each type of basidia found, the genera have increased at 
an alarming rate. The genus Auricularia, based on the common "Jew's 
ear 1 ' has cylindrical basidia with several septa and a sterigma at 
each septum. So it is said and so shown in the familiar figure. 
But we have never seen them as shown. This plant, however, appears 
to us to have different basidia. They are cylindrical and rarely 
septate, but we find no aterigmata except the terminal one. In 
addition the general nature of the plant is not that of any known 
Auricularia but is cerebriform, gelatinous and simulates a Tremella 
rather than an Auricularia* The color is pale brown. The spores 
are 8 X 10, unilateral, with granular contents and are shorter than 
the usual auricular spores. 
EXIDIA DUTHIEI FROM MISS A. V. DUTHIS, SOUTH AFRICA (Fig. 
1594)- There are evidently several tremellaceous species in South 
Africa that do not occur in Europe, We considered two from Miss 
Duthie on page 536. There is a third one in the consignment. 
Exidia Duthiei (Fig. 1594),- Subapplanate with gyrose lobes. 
Color when soaked almost white, with pale pinkish cast. Papillae 
numerous but not easily seen being of the same pale color* I do not 
know another Exidia with subhyaline papillae* In addition to the 
papillae the surface under the microscope is scurfy. Basidia are 
globose, hyaline, deeply imbedded and when mature deeply four- 
parted. The slender sterigmata have a broken effect under the 
&lass. Spores hyaline, 8 X 16, cylindrical, curved with granular 
contents. Its nearest relation is Exidia albida of Europe.
