VII. — Some New Microscopic Fungi.

 Plate III. 



Entomophthora Pooreana sp. n., plate III. fig. 1. 



Hyphae abundant, interwoven, breaking up into short lengths, 

 varying in width from 5 /m upwards, septate ; resting-spores formed 

 in an intercalary manner on anastomosing hyphae, globose, varying 

 from 25 //, to 40 /i in diameter, with a thick yellowish epispore and 

 granular contents. 



Found in the tissue of a rabbit that had been buried in a garden 

 at Isleworth, about 3 in. beneath the surface of the soil, until almost 

 disintegrated. 



The hyphae of this species formed a large part of a waxy-looking 

 white mass of " adipocere " * ; with here and there little clumps of 

 yellow resting-spores. I did not succeed in germinating these spores ; 

 but from the hyphae I got a culture of anastomosing filaments and 

 intercalary resting-spores, which were equal in size to the smallest 

 spores, and otherwise exactly similar to those in the " adipocere " ; 

 the spores produced by culture do not measure above 25 /a in diameter.
