NICARAGUA^ MXYOMYCETES. 



By THOS. H. McBRIDE. 



The species here listed or described are all ^rom material 

 collected in January and February, 1893, by members of the 

 Nicaraguan Expedition, i. e., either by Mr. C. L. Smith or by 

 Mr. B. Shimek. The difficulties of collection and preserva- 

 tion, owing to climatic conditions, were very great. Many spe- 

 cies collected in good condition in the mountainous interior, 

 were more or less seriously affected with mould as soon as 

 they reached the humid atmosphere of Greytown. The speci- 

 mens as soon as taken were fastened by thick glue to the 

 bottoms of shallow but covered paper trays. But for this 

 precaution it is doubtful whether a single Slime-mould would 

 have made the journey from Nicaragua to Iowa. Many of 

 the species are represented by rather scanty quantities of ma- 

 terial but all herein described are in good condition for study, 

 as our figures in the case of the new species plainly show. 



Contrary to all expectation, the Nicaragua Slime-moulds, 

 so far at least as may be determined from material now at 

 hand, are strikingly hke those of our northern United Slates. 

 Of the twenty-five species collected nineteen are identical with 

 those found commonly in eastern Iowa. Six only are new and 

 these represent familiar genera. On the other hand, our most 

 common genus Trichia is wholly unrepresented. This can 

 hardly be an accident as the collection represents a wide area 

 as to habitat, and the most favorable period of the year as 

 regards season.
