decorticated branches of Ilex Aquifoliu^n, near Sheldon Hall 

 (Wk.), April, 1913. The pycnidia were subglobose, scattered or 

 gregarious, about 250 /x diam., black, composed of rather loose 

 parenchymatous dark-olive tissue, soon becoming torn at the 

 summit, and at length excipuliform. Spores clavate-cylindrical or 

 subfusoid, usually obtuse above, hyaline, straight or curvulous, 

 25-35 X 3|-4 [X, very distinctly 3-7 septate, each loculus usually 

 containing a large guttule. Having examined Cooke's original 

 specimens, on decorticated branches of Acer, I find them to be 

 exactly similar (the spores being distinctly septate).

 figs. 30-33. Sacc. Syll. iv, 73. 



Fertile hyphae erect, |-1 mm. high, simple, non-septate, about 

 8-9 /x broad, rather thick-walled ; vesicle globose, 16-18 fj. diam. ; 

 sterile hyphte creeping ; all pale sulphureous or nearly colourless. 

 Capitula about 60 /x diam., sulphur-yellow ; sporophores about 8/x 

 long, clavate, each bearing 2-5 sterigmata, which are lanceolate 

 and of about the same length ; conidia nearly spherical, 2-3 /x 

 diam., yellow in mass. 



Forming effused roundish patches on a rotting fabric, Scar- 

 borough (T. B. Roe), July, 1913. The sterigmata were occasion- 

 ally in twos, but most frequently in threes. I have received 

 exactly the same fungus from West Australia, on mummified 

 pears. 



DIPLOOSPORA gen. nov. 



Conidia uniseptata, catenulata, plus minus ovalia, subhyalina, 

 hyphis erectis brevibus ex mycelio repente oriundis suffulta. 



215. Diploospora rosea sp. n. Mycelio repente, tenuissimo, 

 achroo. Hyphis fertihbus brevissimis, fasciculatis ; conidiis in 

 catenas longiusculas ramosas digestis, oblongis, utrinque apicu- 

 latis, 1-septatis, leniter constrictis, 5-6 x lf-2 /x, roseis. (Tab. 

 512, fig. 8.)

 Koe leg.). 



The tufts of hyplioe were not confluent, but arranged more or 

 less in concentric rings or scattered. They were of a dull pink 

 colour and not above \ mm. high. When seen dry, the chains 

 looked as if the spores were united by isthmuses, but this was due 

 to the apiculate ends. Singly the spores appeared colourless, but 

 they formed masses which had a distinct rosy tint. 



216. Dactylella plumicola sp. n. 



Hyphis sterilibus hyalinis, repentibus, ramosis, laxe intricatis, 

 2-2^ /x cr., ramulos conidiiferos brevissimos hinc inde sparsos 

 gerentibus. Conidiis copiosis, clavulato-ellipticis, 4-10-septatis 

 (septis saopius senis v. septenis), apice obtuse rotundatis, basin 

 versus attenuatis, crasse tunicatis, stipitellatis, loculis gleba oleosa 

 farctis, singulis achrois v. pallidis, coacorvatis dilute melleis, 

 40-60 X 9-10 /x, rarissime 100 /x long. (Tab. 543, fig. 7.)
