longer. Yet it is not attractive for Club members to visit, nor is it 
altogether safe for the Club property, which is exposed to dust, to the 
ravages of rats and mice, and to danger from fire. 
In regard to this matter attention is called to the accompanying circular. 
Among the tough, coriaceous fungi so numerous on fallen branches, 
two kinds, Schizophyllum and Trogia, are of interest because of the 
peculiar appearance of the hymenium. Of the two, the former is much 
more common and conspicuous, and after a little attention is usually 
recognizable on sight; the latter is less often found, partly because it is 
apt to be overlooked on account of its small size and resemblance at first 
sight to the very common species of Stereum. These two genera are 
among those to be recommended for study by those who are taking up 
the forms of tough tree fungi for the first time. 
In collecting fungi that grow on trees it is interesting and important 
to note whether the parasite is limited to one host plant, or is at home 
on several. A list, with specimens, should be kept of the hosts by those 
who like to make a complete record. 
Schizophyllum Fr. 
Dry, coriaceous. Gills fan-wise branched, united above by a tomentose 
pellicle, bifid , split longitudinally at the edge. Spores somewhat round, 
white. On wood. 
A. commune Fr. Very dry, with a stem-like base, pendulous, or hori¬ 
zontal, entire or lobed, covered with whitish gray down. Gills fuscous 
gray, then purplish, more or less villous, revolute at the edge. Spores 
very small. Very common. 
The branched structure of the gills is evident on removal of the pellicle. 
Trogia Fr. 
Gills like folds, channeled or crisped; stem wanting. Soft, flaccid, but 
arid and persistent, texture fibrillose. Reviving when wet. Spores 
white. 
T. crista Fr.— Sessile or nearly so, light yellow-rufescent behind, 
whitish at the margin, minutely cup-shaped at first, then reflexed hori¬ 
zontal, often very irregular and lobed, delicately villous. Gills in the 
form of veins, dichotomous, narrow, crisped, swollen when moist and 
obtuse, but not channeled, whitish or bluish gray. 
On branches, twigs, etc., often on the under side of those lying on the 
ground, or gregarious on logs ; frequently imbricated. Rather common. 
To the variety, which shows bluish or greenish tints on the pileus or 
hymenium, Peck has given the varietal name of variegata. 
In the dried condition the pileus curls under and often conceals the 
hymenium, so that the plant is likely to be passed by as a species of 
Stereum. With moisture the characters appear unmistakably. 
T. Alni Peck. — Thin, coriaceous, resupinate-reflexed, generally imbri¬ 
cated, silky-tomentulose, brownish tawny, the margin sterile; folds of 
the hymenium narrow, irregular, interrupted, wavy or crisped, angular, 
white. Pileus S" to 12" broad. Spores minute, narrow, cylindrical, 
slightly curved, colorless, 5 to 6 -f- p. long. Somewhat resembles T. 
crisp a. The folds disappear to some extent on drying, but reappear with 
moisture. Growing on trunks of alders.
