insufficent descriptions, they must be considered merely as synony- 

 mous with urticce L. 



The antennae of O. Signoreti are frequently deformed, 2 joints 

 often coalescing to form a single joint. 



The other species that I wish to notice just now are some un- 

 described fungi, which I found in Glen Tilt in July and August last. 

 For the elaboration of these I am very greatly indebted to the 

 Rev. M. J. Berkeley. 



Daotylium spirale B. and B. White, sp. n. 



D. candidum e macula tosta oriundum ; floccis simplicibus 

 spiralibus ; sporis magnis uniseptatis medio constrictis utrinque 

 obtusissimis. 



On living leaves of Polygonum vlvlpannn. Glen Tilt, reaching 

 an altitude of 1800 feet. 



Flocci .004 inch long ; spores .0009-.0012, half as much wide. 

 (PI. II. fig. 3.) 



Dactylium modestum B. and B. White, sp. n. 



D. candidum e macula tosta oriundum ; floccis subrectis vel leviter 

 flexuosis ; sporis magnis uniseptatis elongatis medio constrictis. 



On the underside of fading leaves Qi Alchcuiilla alpina. Glen 

 Tilt (alt. about 1300 feet) ; Loch Killein, Inverness-shire (alt. about 

 1000 feet). 



Closely allied to the last, and distinguished not only by the 

 flexuous threads but by the very different spores. 



Flocci .004 inch long ; spores much narrower than in D. spirale. 

 (PI. II. fig. 2). 



Bactridium acutum B. and B. White, sp. n. 



B. candidum parasiticum ; sporis deorsum attenuatis, apice 

 acutis, 1-3-septatis, articulo penultimo tumido. 



On the hymenium of Pezi^a cochlcata. Glen Tilt. 



Distinguished from Bactridium helvclloc by its constantly very 

 acute apex and attenuated base. (PI. II. fig. 4.) 



Milesia B. White, g. n. 



Peridium endophyllum reticulatum, basi inter cellulas matricis 

 radicante ; spora; obovata: cchinulatae ex ostiolo minuto dcmum 

 ejecta). 



Allied to Endophyllum Ldv. Peridium minute, reticulated, im-
