Hypocreaceae. A few species each of Phallaceae, Lycoperda- 

 ceae, Nidulariaceae, Sphaeriaceae, and Pezizaceae are reported. 

 Other groups are represented in the list by only one or two 

 species. Four Laboulbeniaceae have been reported from the 

 island. Up to the present time only one species of Meliola had 

 been recorded from Borneo. 



In examining the data in reference to the number of fungi 

 reported from Borneo it is to be noted that most of the species 

 belong to groups in which the plants are relatively large and 

 conspicuous. Comparatively few representatives of the smaller 

 leaf parasites appear in the list. In listing the fungi reported 

 from Borneo, I have made no attempt to adjust the synonomy 

 and so the actual number of distinct forms is probably consider- 

 ably less than the figures as given above would indicate. The 

 extent of our knowledge of Bornean fungi appears to be at 

 least no greater than that possessed of Philippine fungi previous 

 to 1906 when Ricker's 8 compilation showed less than two hun- 

 dred species to be known from the Archipelago. While no exact 

 data is available at the present time, it is probable that the 

 known Philippine fungi number between 2,000 and 2,500 species. 

 In fact it seems likely that our knowledge of Bornean fungi 

 at the present time is comparatively less than was our knowledge 

 of the Philippine forms in 1906, since in 1906 a proportionately 

 far larger number of inconspicuous forms of Philippine fungi 

 were known than is the case regarding the smaller forms in 

 Borneo. 



The present paper gives the results of a study of a small 

 collection of fungi secured by the writer during a recent visit 

 to British North Borneo. The fungi were collected incidental 

 to other work and were mostly secured in the lowlands along 

 the coast as no time was available for excursions into the forests 

 of the interior. As is to be expected a large proportion of the 

 specimens secured are referable to well known and widely dis- 

 tributed species. Five apparently new species are described and 

 a number previously unknown from Borneo are recorded.
