PROFESSOR ORESTE MATTIROLO 
It is a pleasure to add to our gallery of mycological por¬ 
traits that of Professor Oreste Mattirolo who is very prominent in the 
mycologival world in Italy. 
Professor Mattirolo was born December 7th, 1856, and is there¬ 
fore at present sixty-four years of age. 
He secured his Doctor's degree in Medicine and in Science 
from the University of Turin and later studied at the University of 
Strassburg for two years (1378-80, 1830-81 ) in the Laboratory of M. 
de Bary. For the past twenty years Dr, Mattirolo has been Director of 
the Botanical Garden and Professor of Botany of the University of Turin, 
having previously served in the same capacity in the University of 
Bologna and the Istituto di Studi Superior! of Florence, He is now 
President of the Royal Academy of Agriculture, 
Professor Mattirolo : s activities have covered a wide field 
from phaenogamic and agricultural botany to all branches of mycology, 
his specialty being the difficult section known as hypogeal fungi. He 
is perhaps the best informed man in Europe on this subject today. He 
has published a great deal on the hypogeal fungi o i Italy and has 
promised a paper oil our North American hypogeal fungi which has been 
delayed, he writes me, by the interruptions of the war. One who lives 
in Italy has special opportunities for studying hypogeal fungi, for 
Italy is really the birthplace of the study. The first mycologist who 
ever investigated this difficult branch was Vittadini whose work is 
still an authority on the subject and he is the father of the study of 
hypogeal fungi. Then it was taken up by Tulasne who issued, at Paris, 
a beautiful monograph. These two men and Professor Mattirolo have 
given us practically all that is known of tne subject. We presume 
there is not in Europe another collection of hypogeal fungi as exten¬ 
sive as that in the private herbarium of Prof. Mattirolo, and on our 
next trip to Europe it is our intention to make a special visit to 
Italy in order to see this collection. We have corresponded with Prof, 
Mattirolo. for a number of years and have always relied on him for what 
little knowledge of hypogeal fungi we have. I am sure Prof, Mattirolo 
would be glad to give critical advice to any one collecting hypogeal 
fungi and it would certainly aid in getting a correct idea of the 
subject if some of our students who are publishing on the subject 
would send their material to Prof, Mattirolo and really learn some¬ 
thing about it. He is still actively interested in the subject and 
I trust he will find time to publish a systematic resume of hypogeal 
fungi. 
0. P. FERNANDO THE IS ZEN, S. J. 
We are glad to present a photograph of Rev. Theiszen whose 
tragic death occurred a little more than a year ago, September 5th, 
1919. Rev, Theiszen was a member of the Society of Jesus and was
