1888-89.] Fungi collected in Hardanger in 1887. 491 



Hypoxylon fuscum, Fr., on dead branch of Corylus Avellana. 

 Vik. 



Sphaerella recutita (Fr.), C. and De Not., on dead leaves of 

 Deschampsia ccesjntosa. Jordal. 



S. Asplenii, Awd., in dead fronds of Asplenium septentrionale. 

 Graven. 



Venturia Alchemillae (Grev.), B. and Br., on leaves of Alchemilla 

 vulgaris. Jordal. 



Leptospheeria Dumetorum, Niessl, var. Galii-borealis. On 

 dead stems of Galium, horeale, at Vik. This differs from 

 Niessl's type chiefly in its smaller size. Perithecia about 1 40 /x 

 in diameter ; asci 40-50 by 6-8 /x, clavate, or cylindrical with 

 a short stalk ; sporidia 2- or 3-rowed, each measuring 12-15 

 by 2|-3 yu,, pale brown, 3-septate, second cell slightly or not at 

 all larger than the neighbouring cells. In other respects this 

 agrees with the type. 



L. quadriseptata, sp. n. On dead stems of Thalidrum minus, 

 Valeriana officinalis, Lactuca muralis, and Rumex Acetosa. 

 Jordal and Vik. Perithecia scattered, covered by the epiderm, 

 globose \-\ mm. in diameter, ostiole short ; asci 8-spored, sub- 

 clavate, stalked, 60-80 /a by 8-9 /^ ; sporidia distichous or 

 tristichous, fusiform, often inequilateral and curved, always 

 4-septate, second cell protuberant, 23-32 ix by 4-5 yu., pale brown ; 

 sometimes each cell is guttulate ; paraphyses numerous, slender, 

 hyaline, pluriguttulate, longer than the asci. Seems to approach 

 nearest to L. fcenicidacea, Fabre ; but is remarkably constant 

 in its characters on all the above food plants. 



L. dolioloides (Awd.), Karst., on dead stems of Achillea Mille- 

 folium. Vik. 



L. Silenes-acaulis, De Not., on Silene acaidis. Simodal. 



L. CTilmicola (Fr.), Karst., on a dead grass. Vik. 



L. culmifraga (Fr.), Ces. and De Not., on Deschampsia ccespitosa. 

 Jordal. 



Sphserulina intermixta (B. and Br.), Sacc, on twigs of Rosa 

 canina. Jordal. 



Metasphseria Empetri (Fr.), Sacc, on Empetrum nigrum. Odde 

 and Vik. 



Pleospora Andropogonis, Niessl, var. Actaese, an sp. nova. On 

 dead stems of Aetata spicata, in Jordal, I found a Pleospora, 

 which comes so near P. Andropogonis, Niessl, that, despite the 

 difference of host plants, I can find no sufficient specific dis- 

 tinction ; though, as both asci and sporidia are smaller, it may 

 deserve a varietal name as above. It differs from Niessl's 

 description thus : — Perithecia x 220 yu. ; asci 75-85 x 14-15 /i,
