BERKELEY’S TYPES OF FUNGI. 503 
PEZIZA LACHNODERMA, Berk. in Hook. f. Fl. Tasm. ii. p. 274 
(1860). 
Gregarious or scattered, shortly but distinctly stipitate; stem 
black, especially at the base ; margin at first incurved and almost 
closed, then expanding until nearly plane, but the margin per- 
sistently more or less upraised ; externally pure white, densely 
downy, hairs thin-walled, cylindrical, obtuse, septate, hyaline, 
often very minutely rough with particles of lime, 70-100 x 5-6 u, 
often slightly curved; sometimes the hairs disappear, except at 
the margin, leaving the exterior of the ascophore bald; dise 
yellow to deep orange-red ; laterally compressed and elosed when 
dry, 3-4 mm. diameter; asci clavate, apex slightly narrowed, 
blue with iodine, 60-70 x 6-8 u ; spores 8, irregularly 2-seriate, 
hyaline, smooth, continuous at first, then 1-septate (possibly 3- 
septate at maturity), linear-fusiform, usually slightly curved, 
ends acuminate, 23-30 x 2 p; paraphyses slender, very slightly 
thickened at the tip and the point narrowed, delicately septate ; 
hypothecium and excipulum formed of slender interwoven hyphe 
which become converted into small, elongated hexagonal cells 
radiating from base to margin at the periphery. 
Dasyscypha lachnoderma, Sace. Syll. viii. n. 1804 (in part.). 
Peziza melanopus, Berk. & Curt. Cuban Fungi, n. 674, in 
Journ. Linn. Soe. vol. x. (1869) p. 367. 
Sarcoscypha melanopus, Sace. Syll. viii. n. 634. 
The type of P. lachnoderma is from Tasmania, on bark and 
branches (Archer). Other specimens in the herbarium are from 
Brisbane (Batley, nn. 572 and 1804); Natal (MacOwan, nn. 
156, 194, 1126). The type of P. melanopus, Berk. & Curt., from 
Cuba (Wright, n. 368), proves to be identical with P. lachno- 
derma. Not any of the specimens mentioned above are growing 
on bark or wood of conifers. 
Dr. Rehm described in Grevillea, vol. iv. (1876) p. 169, under 
the name of Peziza Ellisiana, a minute Peziza growing on pine- 
bark, collected by J. B. Ellis at Newfield, New Jersey, U.S.A. 
This species was afterwards issued in Rehm’s Ascom. n. 303 
as Dasyscypha Ellisiana, Rehm. Some time afterwards Rehm 
sent out a new label for his Ascom. n. 303, in which he substi- 
tuted the name Dasyscypha lachnoderma (Berk.), Rehm. This 
was unfortunate, as the American plant is quite distinct, differing 
from P. lachnoderma, Berk., more especially in the following 
points :—Ascophore smaller, not so distinctly stipitate; stem
