120 MYCETOZOA OF ANTIGUA AND DOMINICA. 



36. Lamproderma arcyrionema Eost. On decayed leaves of 

 cocoanut palm, Antigua. Two gatherings with stalks 1-8 mm. 

 long; the capillitiiun is dark and much crisped. "It was quite 

 lustrous," Mr. Cran writes, "when first seen, though almost black 

 wath perhaps a slightly yellowish tinge ; under the microscope the 

 enclosing membrane looked like polished silver." 



37. Lamproderma irideum Mass. On dead leaves, Antigua. 

 Two very typical specimens, though the dark branches of the 

 capillitium are less pale than usual at their point of attachment to 

 the apex of the columella ; the spores measure 7 /^, and are marked 

 with the normal number of about eight warts across the hemisphere. 



38. Cribraria tenella Schrad. There are two specimens from 

 Antigua on dead wood, andone from Dominica. Inall,the sporangium- 

 net is regular, with scarcely the rudiments of a cup ; the nodes of the 

 net are round, seldom triangular, and without free rays. 



39. Cribraria languescens Eex. Antigua. " The Plasmodium 

 is dark reddish-brown, rising out of rotten wood in little cushions, as 

 in Dictijdium umhilicatuw.'' We have three fine gatherings of this 

 graceful species, which Mr. Cran finds is abundant in the island. 

 They are similar to the types from Dr. Rex. Judgiug from the 

 examples we have seen, its character appears to be, for a Cribraria, 

 remarkably constant. We have no record of the species having before 

 been obtained, except from three of the States of North America. 



40. Cribraria violacea Rex. There are two gatherings on dead 

 wood from Antigua of this delicate and beautiful species. The 

 sporangia measure O'Ol mm. diam. I may mention that a frag- 

 ment of ash-stick was sent by me from Lyme Regis to Miss A. L. 

 Smith at the British Museum for the examination of a small fungus 

 growing on it. The stick was kept moist under a glass shade for 

 some weeks, when a fine grow^th of Cribraria violacea was found to 

 have developed ; the sporangia are larger than those from Antigua, 

 measuring 0-025 mm., but similar to those collected by Mr. Saunders 

 in Buckinghamshire and by Dr. Rex from near Philadelphia. 



41. DicTYDiuM umbilicatum Schrad. On dead wood, Antigua. 

 This is the common form received from all parts of the world, and 

 always singularly constant in character. The brown variety with 

 a symmetrical cup (referred to in the Brit. Mus. Cat. Myc. p. 148), 

 though less frequent, is also cosmopolitan, and is so little subject 

 to variation that it deserves a varietal, if not a specific, distinction. 

 I mark it as Ya,v. fuscum. 



42. TuBULiNA sTiPiTATA Rost. On dead wood, Antigua. A single 

 specimen of three shortly stipitate clusters. The spores measure 

 4 fjL diam. 



48. HEMiTRicmA CLAVATA Rost. Two gatherings from Antigua 

 on dead wood. The sporangia are of the usual form and colour ; 

 the spores are exceptionally small, measuring 6 /x in one specimen, 

 and 7 /x in the other. 



44. Hemitrichia Serpula Rost, On dead wood, Antigua. The 

 gatherings received of this species are interesting as illustrating the
