On decaying fungi. Extremely common. Frequently penetrating 

 the whole fungus and converting it into yellow dust. — Sporidia globose^ 

 certainly echinulate, at least when dry, as observed by Klotzsch in 

 Hook. Herb.

 "white, sporidia red appendiculated. Fr. St/st. Myc. v. 3. p. 438.

On decaying fungi. On Agariciis vellercus. Appin, Captain Car- 

 michael. Inverary, Klotzsch in Hook. Herb. — More superficial than 

 the last. Sporidia larger, globose, with a broad pellucid border and a 

 thick blunt appendage. This should perhaps form a distinct genus, the 

 sporidia in the young state being apparently attached by the peduncle 

 to ihe flocci. I have however only seen dry specimens.

 on the matrix. Septa none or evanescent. — Name, fusus, a 

 spindle, and a-o^^og, seed. 



1. jp. atrovhens, Berk, {darh-grecn Fusisporiuni) ; flocci 

 efi'used white, sporidia at first greyish-green then green-black 

 strongly curved. 



On onions. Summer. King's Cliffe, Norths. Rev. M. J. Berkeley. 

 ^—Sporidia forming about the third of a circle. Originating in little 

 dot-like spots v»'ith radiating flocci crowned with a gelatinous greyish 

 mass ; these at length unite and the whole of the centre is occupied 

 by the sporidia, the border still increasing and quite fleecy if meeting 

 with any impediment ; at length the whole is green-black and the 

 border obliterated. This is at least one cause of the mildew which is 

 so destructive to onions, just before they arrive at perfection.

On decayed cucumbers, gourds, Sec. Ajiethorpc, Norths. Rev. M. 

 J. Berkeley. — At first clothed with fleecy white branched. //orr/, which 

 spread beyond the mass of the sporidia, and at length vaniah, leaving a 

 treinelloid stratum. Sjjoridia septate, se^du evanescent. It does not 

 always commence in downy patches, but sometimes in little dot-like 

 gelatinous masses, which at length become confluent, without any 

 mycelium.
