III. Veltjtina. 
The IIyphoeoma Lacrimabundum Group. 
Hypholoma lacrimabundum Fr. PL LXXYIIB C and LXXVIIL 
Typical Hypholoma lacrimabundum is shown in Pl. 
LXXYII C. compare Atkinson’s fig. 28. The pileus is covered 
with tawny fuscous scales composed of tufted fibers on a whit¬ 
ish background. The flesh is whitish and also the fibers of the 
annulus. The plants are umber rather than tawny when dry. 
The plants in PI. LXXVIII differ somewhat. They are 
very large and dull tawny yellow with concolorous flesh and veil. 
The gills are very white floeoulose on the edges and the spores are 
smaller 3—5x7-—8/*. The plants appear to be what Atkinson 
has described as Hypholoma echinieeps, Ann. My col. 1909 p. 
371. They agree in the large size, Atkinson gives the dimen¬ 
sions 12 — 14 cm. high, 3—7 cm. across the pileus and the stem 
8—12 mm. thick, in the densely scaly pileus of the young plants, 
in the ochraceous brown colors, in the ample veil which in our 
plants soon disappears and in the size of the spores and basidia. 
Spores 3.5—5x7 —9a. Basidia 7x28 — 30/a. We did not ex¬ 
amine fresh plants for cystidia which Atkinson says are in clus¬ 
ters of 2—8 and 10 — 1 2/a thick, extending 30—40/a above the hy¬ 
men! um . Atkinson says the plants are similar to Hypholoma 
pyrotrichum but have smaller spores and more dense scales in 
the center of the pileus. The spores are not only smaller but 
entirely different in character from those of Hypholoma py¬ 
rotrichum which belongs to the Hypholoma velutinum group. 
Our plants are very close to Hypholoma lacrimabundum. Pl. 
LXXYII B shows an intermediate form which cannot be dis¬ 
tinguished in the photograph from LXXYII C except by the 
thinner stem. 
The plants grow in damp grassy places and in pastures and 
about stumps and logs in woods. The collection from which Pl. 
LXXYII 0 was taken was found by an oak stump in a pasture 
at Glencoe, Ill. The photograph has been published already by 
Hr. W. S. Moffatt in Bull. VII, Pl. XI of the Chicago Acad, of 
Sciences.
