and they would not intentionally commit a breach of ethics. They will 
learn much yet about the genera and species of their specialty, and I 
rather feel that some of their published conclusions are premature. 
For instance, they announce a new species of MacOwanites from our West, 
While I have not seen the specimen on which this was 'based, I believe 
they have about the same chance of finding a species of MacOwanites 
in the United States that they have of finding a kangaroo. 
Professor Mattirolo is a man who has spent years on the study 
of hypogeal fungi. He has, without doubt, the largest collection of 
specimens of these plants and the largest experience with them, and 
with me his opinions on this subject have more weight than those of 
any one else. At the same time the limitations of genera.are matters 
of individual opinion, and Mr. Dodge, if he was right in considering 
the Mauritian species at all, was right in my view,, in including it in 
Rhiznpogon. I have always maintained it is better to stretch the 
limits of old genera than to erect new. ones on slight differences. 
The peridium of Anthrocophlous is black and of a different hyphal 
structure from that of all Rhizopogons as. Prof. Mattirolo demonstrates 
in his. article, but the gleba.and spores are exactly the same as those 
of Rhizopogon, and this, class of plants has in the past been classi¬ 
fied mostly on their spore and gleba characters. 
NOTE 1050 - XYLARIA GUEPINI.- A plate of this, rare plant is 
issued in the last fascicle of the ”Flora.Batava". While we have 
seen but one collection, which was distributed in the old Italian 
exsiccatae, we judge from Fries’ de&cription that this plant is correct¬ 
ly determined as illustrated in Flora Batava* It is a very exceptional 
Xylaria, not black as are most Xylerias but brown and is evidently 
very closely related to Xylaria rhizophila of Australia, considered 
page 936 Mycological Notes. Fries received this plant from Guepin, 
France and gave a description of it in Elenchus, Vol.2. Cesati found 
a plant in Italy that he referred to Fries' description and gave a 
figure. It is a very doubtful question as to whether the plant Cesati 
found and the plant Fries named are the same plant. I never could 
reconcile Cesati’s figure to Fries’ description and it is surely not 
the plant that has just been illustrated in Flora Batava. Notwith¬ 
standing, they write the name Xylaria. C-uepini (Fries) Cesati. It is 
stated in Flora Batava that Xylaria Guepini occurs in North Italy, 
France, Brazil, Ceylon and Borneo. As a matter of fact it is a very 
rare species, collected very few times and the only certain localities 
are France and Holland. The records in northern Italy, Ceylon and 
Borneo are all mis-determinations,
