Fr. Bul. 15: 194. pl. 9, f. 4. 1899; басс. Syll. Fung. 16: 50. 1902. 
Plate 1, fig. 5. 
Craterellus pulverulentus Berkeley & Curtis, Linn. Soc. Bot. 
Jour. 10: 328. 1868; басе. Syll. Fung. 6: 520. 1888. 
Type: in Kew Herb. and Curtis Herb. 
Fructification pallid ferruginous; pileus orbicular, pulverulent, 
the margin inflexed; stem thickened towards the base, black; 
hymenium sparingly venose, colored like the pileus. 
Pileus 2 mm. broad; stem 216 mm. long. 
On bark of sticks. Cuba and Porto Rico. May and July. 
A collection of a dozen or so fructifications from Porto Rico by 
Professor Stevens, taken in connection with specimens of the 
type collection in Curtis Herb., shows that while the original 
description of C. pulverulenta by Berkeley & Curtis, literally 
translated above, is correct as far as it goes it does not give details 
enough for critical comparison with C. minima. The specimens 
of C. pulverulenta are plano-convex rather than campanulate 
as stated by Patouillard, and the margin only slightly inflexed, 
entire but slightly notched behind near point of attachment of 
the stem which is sometimes nearly central but usually distinctly 
eccentric. The spores are hyaline, even, 314 x 2 y in the type, 
3-6 x 2-214 y in more copious occurrence in the Porto Rican 
gathering, and the hyphae slightly colored, 3-4 y in diameter. 
The dry specimens in Curtis Herbarium now have the upper 
surface of the pileus Natal brown of Ridgway and the hymenium 
and the stem bone-brown. 
Specimens examined: 
Cuba: C. Wright, 564, type (in Curtis Herb.). 
Porto Rico: Monte Alegullo, F. L. Sievens, 1358 (in Mo. Bot. 
Gard. Herb., 55402, and Stevens Herb.). 
3. C. marasmioides (Berk. & Curtis) Patouillard, Soc. Myc.

Jour. 10: 328. 1868; Басс. Syll. Fung. 6: 520. 1888.
