respects : (1) they were on bare ground, not on Juncus ; (2) they 

 formed large patches, 6-8 inches broad, looking to the naked eye 

 exactly like Trichothecmm roseiim ; (3) the conidia were more 

 granular, not hyaline, and thus presented a more decided rosy 

 tinge when viewed singly under the microscope. 



The conidia were in long chains, gradually growing shorter 

 towards the end of each chain, but retaining the same breadth ; 

 they measured 12-30 x 9-10 /x, the terminal ones being almost 

 cuboid. The cells of the hyphae were similar but more closely 

 connected, so that they did not fall away, as the conidia easily 

 did, on the addition of water.

Mycelium widely creeping, intricate, with numerous septa ; 

 conidiophores erect, 250-300 fx high, 10 /x thick, tapering very 

 slightly upwards, remotely septate, terminating in a subgiobose 

 or oblong vesicle which is covered with numerous papillae ; hyphse 

 often densely granular, pink ; vesicle nearly colourless or faintly 

 yellow. Conidia of all sizes, at first roundish or ovate, then 

 oblong-obovate, finally 26-30 x 12 /x, smooth, granular, distinctly 

 pink, forming a rather crowded spherical head, 70-80 /x diam.

Forming widely effused, woolly-looking, clear rosy tracts, of 

 the colour of Trichothecmm roseum, on mosses grov»'ing under a 

 bell-glass, and spreading thence to the wet blotting-paper on 

 which they were placed, Edgbaston, November. CE. roseum Cooke 

 is only the early state of this species, as was manifest on watching 

 the various stages of growth under the bell-glass. 



144. Penicillium ovoideum Pr. Fung. Hoy. no. 272 ; Sacc. 

 Syll. Fung. iv. 81. 



Forming a thin white crust; fertile hyphse fasciculate, 0-2 mm. 

 high ; fascicles branched, composed of many delicate hyphae, 3-4 /x 

 diam., ending in a cluster of more or less penicillate ramuli, each 

 bearing a chain of 20-30 conidia. Conidia hyaline, smooth, ovoid 

 or ovoid-oblong, averaging 8 x 4 /x. (Tab. 515, fig. 3.) 



On size. Lower Edmonton, Mr. James Scott, March. Preuss 

 found his specimens on damp fish-glue. 



145. Sporotrichum chrysospermum Harz. Hyphom. p. 19, 

 t. 5, f. 3 ; Sacc. Syll. Fung. iv. 104. 



Effused ; mycelium white, vaguely branched, tortuous and 

 intricate, becoming yellow, septate and denticulate towards the 

 ends, 4 /x diam. Conidia broadly oval, rounded above, subacute 

 below, perfectly smooth, bright golden-yellow, 7-10 x 5-6 /x. 

 (Tab. 515, fig. 4.) 



On a dead stick, Sutton Park (Wk.), August. The conidia are 

 either borne on the denticules or sessile ; in the former case the 

 denticule often falls off with them. Differs from S. Iceticolor 

 C. et M. (Grev. xx. 38) in the form of the conidia, but evidently 

 closely allied.
