ters that they can readily be kept in the order ol classifi¬ 
cation. I am in hopes sufficient interest will be awakened 
so that I will feel justified in gradually issuing these photo¬ 
graphs and descriptions, until the field is fairly well covered. 
Recognizing the growing interest in “edible fungi” I shall 
give preference in illustrating to those of economic value. 
Since I have been working with the fungi it has been 
my custom to photograph those I have found and the result 
is that I have now over 450 6^x8^ plates of our native fungi. 
I have received many compliments regarding my photographs 
that I feel, should, with greater justice, have been given to 
the lens. Photography I consider to be largely mechanical, 
and anyone with a good lens and suitable apparatus ought 
with practice to succeed. In photographing fungi, it is ne¬ 
cessary to have a ‘‘long focus” lens capable of covering, nat¬ 
ural size of the object, a 6Jx8J plate and with perfect achro¬ 
matic properties and what is known as “depth of focus”. 
Such a lens with camera will cost about $150.00. Every 
mycological club, and all students who can afford it should 
be equipped with this outfit, and I will be pleased to give 
further information in detail to those requesting it. 
2—HYDNUM TINCTORIUM. 
A Hydnum Analagous to Fomes. 
Description .—Pileus dimidiate, sessile, hard, woody. 
Upper surface dark, almost black, concentrically zoned, (each 
zone I think, represents an annual growth) the outer (more 
recent) zone is brown. 
Interior substance bright dark red color, hard. 
Teeth numerous, about a cm. long, 2 mm. thick, acute, 
firm, light brown color, the interior dark red, under the mi¬ 
croscope covered with spines as in Prof. Ellis’ genus, Mu- 
cronoporus. 
Spores hyaline, broadly elliptical, 4x6 me. 
Specimen received was 18 cm. long, 9 cm. wide, and 7 
cm. deep. It is evidently of several years’ growth. Traces 
of the teeth structure can be observed for 3 cm. into the sub¬ 
stance of the pileus and it is evident that as the teeth grow 
each year, the substance of the pileus fills in between them 
at the base.
