SEAVER: BERMUDA FUNGI 503 



distinct in spore characters. Perhaps the most interesting fact in 

 regard to the discomycetes of the Bermudas was the collection of 

 several European species, which so far as the writer is able to learn 

 have not previously been known from North America. 



One of the most interesting of these is Detonia Planchonis Boud. 

 a small purple cup-fungus about i cm. in diameter. This species 

 was found on damp soil by roadsides and on bare soil in fields 

 throughout the Bermudas. While this is the commonest cup- 

 fungus in the islands and is large enough to be easily seen, there 

 is no record of the species having been previously collected either 

 in Bermuda or elsewhere in North America. 



Another species of equal interest is Sarcoscypha minusciila Boud. 

 On account of its small size this species might easily be overlooked. 

 The species was originally described from material collected in 

 Portugal on dead foliage of cedar. The species while not abundant 

 was frequently collected and there is no record of the species having 

 been previously collected in North America. Among the peculi- 

 arities of this species are the asci,, which are marked by an external 

 thickened ring near their apices. This gives to the ascus when 

 seen in profile the appearance of having two minute ears. This 

 structure of the ascus is very different from that of StreptotJieca, in 

 which genus the thickened ring about the ascus projects inward 

 instead of outward. 



Of the more common species of discomycetes, we were interested 

 in noting the occurrence of Pyronema omphalodes (Bull.) Fuckel on 

 burnt places. This species, which has proved to be of unusual in- 

 terest to morphologists, appears to have a very wide distribution. 

 The coprophilous discomycetes were found to be common and quite 

 abundant. A number of species of the Hysteriales and Phacidiales 

 were collected, five of which have received specific names. 



The Perisporiaceae or "sooty moulds, " which are essentially 

 tropical fungi occurring as parasites or epiphytes on the leaves and 

 stems of the higher plants, were found to be quite abundant. Since 

 in many cases the mycelium occurred without any trace of peri- 

 thecia, it was impossible in such cases to make specific determina- 

 tions. Four species have been definitely determined. 



Eight species of the HypocreaJes were collected, three of which 

 are described as new. One of the new species is Nectria Lantanae, 

 a minute species which was found to be common on the dead leaves
