exsiccati No. 106 a & b). This gives also the explanation of Mr. Rostrur's 
finding Trochila juncicola in many places, where other investigators did 
not find it, and on the other hand, Mr. Rostrur's never finding Naevia 
pusilla. 
This species is for the first time found by Md. Liserr on Juncus 
conglomeratus at Malmedy in Belgium and placed in her herbarium as 
Stictis pusilla, but she has never published that name. After her death 
her collection was distributed both by Thümen in Mycotheca universalis 
No. 1662 and by ROUMEGUÈRE in Fungi Gallici No. 663 and described as 
well as Trochila pusilla (Lis.) by SPEGAZZINI and ROUMEGUERE (80, pag. 20) 
as by CookE (80, pag. 85) as Mollisia perpusilla (Li8.) Cooke. Rerum has 
found it in Bavaria and distributed the same in his Exsiccat: Ascomycetes 
No. 608 and described it in Hedwigia 1882, pag. 67 as Mollisia aberrans. 
KRIEGER found it in Sachsen (Fungi saxonici No. 40) and Jaap in 
Thürmsıa on Juncus effusus and in Mecklenburg on Juncus balticus 
besides on the island Rome; VESTERGREN found it also on Juncus balticus 
on Oesel (Russia) (Micromycetes rariores select. No. 221) and STARBÄCK 
(89, pag. 20) on Juncus effusus on Øland (Sweden). Warming (Rosrrup 
86) found it at Kaafjord in Finmark on Juncus compressus; it is further 
noticed from Norway (BLytr 91 & Rostr. Asc.) on Juncus arcticus and 
trifidus and Luzula arctica, parviflora and pilosa; from Iceland (Rostrur 
03) on Juncus balticus and filiformis and Luzula multiflora; from Greenland 
(Rostrup 88) on Juncus trifidus and triglumis and Luzula arctica, arcuata, 
confusa, multiflora and spicata, and finally in Ellesmereland (Rostrup 06) 
on Luzula nivalis, and on Jan-Mayen (OSTENF. 97). 
It will be seen, that this little fungus has a very great propagation 
and is found on many different host plants; it is easy distinguished by its 
wide spread, at first globular and immersed apothecia, which later break 
out through the epidermis, cutting in this a circular opening of the size of 
the discus, the cut-off cover is often attached to one side as a flap 
or gets loose and drops off. It is found at summer time on withered 
leaves and stems of the above mentioned Juncaceae.
