320 THAXTER. 



I have collected this species in abundance in the Maraval Valley 

 near Port of Spain, Trinidad, growing subgregariously along the 

 Maraval brook in moist bamboo trash, fruiting within this material 

 and running out to produce its fructifications on the surrounding sand 

 and pebbles. A single specimen was also found under the leaf cover 

 in the forest about the Grand Etang, Grenada; and I obtained 

 several typical specimens growing exposed on rotten logs in Boggs' 

 Hammock, a short distance south of Cocoanut Grove, Florida. 



Dr. Lindau has been so kind as to send me a fragment of the type of 

 E. Moelleri, described by Hennings from Brazil. This material is, as 

 above indicated, identical with the Trinidad form, which has been 

 submitted to M. Patouillard and is pronounced by him in all respects 

 the same as his E. lignicola. The spores of the Brazilian form have 

 the darker color which seems to be more characteristic of individuals 

 which have developed in humus, without exposure to the light and air, 

 and are, as in the Grenada gathering, sometimes almost opaque when 

 first mounted. 



Mr. Lloyd has also been so kind as to send me a portion of the 

 Jamaica material figured by him (1. c.) as E. pidvinata Hennings, as 

 well as a second specimen collected by Mr. Brace in the Bahamas. 

 These gatherings also correspond in all respects to the Trinidad form, 

 and must be regarded as typical E. fulva. I have further received from 

 Professor Mattirolo for examination, a specimen collected by Rick in 

 Brazil, which also has all the essential characters of the present spe- 

 cies, although the spores are not turgescent: and from Professor 

 Spegazzini a gathering from La Boca, Buenos Aires, doubtfully de- 

 termined as A. argentina, which seems quite typical of this species, 

 although not in very good condition. 



The spore-masses of E. fulva vary from 1^ cm. to a few mm. in 

 diameter when dry, and are usually umbilicate below, subspherical to 

 flattened and irregularly lobed; and even in the same gathering there 

 may be great variation in color. The peridium, which is usually well 

 developed, although in some specimens it may be absent to a greater 

 or less extent, exposing the naked spore-mass, is at first pure white and 

 floccose in young fresh individuals, turning brownish with age, or 

 when handled, the color deepening from ochraceous tawny to chestnut 

 brown. 



The hyphae are of the usual type, rather stout, 8-12 (x in diameter, 

 more or less, often nodulose or irregular, showing occasional septa, 

 which are more frequent than in most other species, and are in some 

 cases quite loosely interwoven.
