23 
On the ground. 
Type locality: Cuba. 
Distribution : Known only from the type locality. 
Illustrations: Cooke, Mycogr. pi. 69, f. 265. 
A cotype specimen of this species has been studied. The 
species is well-marked by its size and by the peculiar markings 
of the spores, which are not mentioned in the original description. 
23. Lamprospora polytrichina (Rehm) 
Detonia polytrichina Rehm, Krypt. FI. i 3 : 1269. 1896. 
Plants gregarious, sessile, expanding, becoming nearly plane 
or shallow cup-shaped, margin entire and often wavy, reaching a 
diameter of 5 mm., hymenium bright orange, externally lighter, 
whitish and more or less pruinose; asci cylindric or subcylindric, 
gradually tapering near the base, reaching a length of 200-225 
and about 17 thick near the apex; spores i-seriate, entirely 
globose, with one or sometimes several oil-drops, smooth, hyaline, 
1 5—1 7 yu. in diameter; paraphyses slender, slightly enlarged above, 
straight or slightly curved. 
On soil among moss, especially Poly trichum. 
Type locality: Europe. 
Distribution : Minnesota ; also in Europe. 
Illustrations: Cooke, Mycogr. pi. 13, f. 50. 
The only specimens of this species examined from America 
were those collected by Miss Hone in Minnesota (No. 938 ). 
The species has been confused with Peziza Polytrichi Schum. 
Doubtful Species 
Peziza cxasperata Berk. & Curt. Grevillea 3: 152. 1874. 
The plants are described as one-half inch across, externally 
warted and with the margin indexed, spores rough and about 
12 fi in diameter. 
The species was collected in Alabama by Peters. 
Peziza globifera Berk. & Curt. Jour. Linn. Soc. 10: 366. 1869. 
A Cuban species with smooth spores. My only knowledge of 
this and the preceding species is based on the examination of 
microscopic slide of the spores.
