shown in previously published papers. In a recent experiment 
the speaker was able to show that the spores of this fungus which 
had been kept nearly three years in the herbarium germinated 
readily in hanging-drop culture. This last point should be of 
general interest to teachers of botany since it means that the 
plant can be grown and studied from living material and the old 
plants then placed in an envelope and kept until the next year 
when they can be planted and grown again. No complicated 
technique is necessary for the growing of Pyronema. A pot of 
garden soil should be heated. Heating can be carried on in an 
autoclav or sterilizing oven. If these are not to be had bake 
in an ordinary oven. Saturate the soil with tap water after 
heating and plant the spores. Growth of mycelium should be 
abundant in two or three days, sex organs should appear in 
about a week and mature ascocarps a few days later. А more 
detailed account of this subject will appear in the BULLETIN of 
the Club. 
Dr. Marshall A. Howe spoke briefly on “Some Marine Algae 
from the Stomach of a Peruvian Green Turtle" and exhibited 
specimens from the source indicated, collected in Peru by Dr. 
Robert E. Coker. The fragments were in a good state of preser- 
vation and two of the species concerned are readily determinable, 
the most abundant being Rhodyminia flabellifolia, a common 
Peruvian and Chilean species and a close relative of the edible 
“dulse.” The alga coming next in point of abundance is 
Caulerpa flagelliformis ligulata, a species occurring elsewhere in 
Dr. Coker’s Peruvian collections but not before reported from 
the shores of the American continent. Fragments of a species 
of Gelidium not so certainly determinable also occur. 
Dr. W. A. Murrill gave a short account of the progress of his 
studies on the Agaricaceae of tropical North America and also 
read some mycological notes relating to the Washington meeting. 
Meeting adjourned.
