SUPPLEMENT TO WELWITSCH's AFRICAN FUNGI. 177 



Hill (some of these specimens are not quite characteristic) ; identical 

 with the plants of Fries, Herb. Normale, at Kew and British 

 Museum, except in being smaller; it does not seem to us to be a 

 very good variety. C. capillaris is luxuriant on wet slopes at 

 Ardsgionaich Point ; even last summer, which was exceptionally 

 dry, it often reached a height of 12-14 in. We cannot think such 

 states worthy of varietal distinction ; no doubt the same objection 

 may apply to several recognized dwarf "varieties," such as the 

 following. — C. externa Good. var. pumila Andersson. 107.''' Damp 

 pastures by Loch Fleet.— C. Oederi Eetz. 107. Near Loch Fleet. 

 108. S. side of the Kyle of Tongue. 109. Holburn Head, in moist 

 hollows ; a very reduced state. 



Milium effusum L. 107. Dunrobin Glen. 



Agrostis palustris Hudson. Both var. maritima Meyer and var. 

 coarctata (Hoffmann) were noticed between Edderton and Tain. 



Deschampsia discolor Roemer & Schultes. 108. Marshy ground 

 bordering on Loch Naver, Altnaharra. 



Holcus mollis L. 107.''' Near Golspie. Avena pratensis L.''' was 

 also seen here. 



Poa nemoralis L. var. Paniellii Hooker & Arnott. 95. Shaded 

 rocks above the Divie, nearly opposite Relugas House, Dunphail. 

 Festuca sijlvatica Vill. grows hard by. 



Glyceria maritima Mert. & Koch. 107.* Muddy shores, Loch Fleet. 



Bromus ramosus Hudson. 107. Dunrobin Glen. 



Ehjmus arenarius L. 108. Melness Sands ; locally abundant. 



Asplenium marimun L. 107. Cliffs between Brora and Golspie; 

 scarce. 108. Coast of Tongue Bay, both on the E. and W. sides, 

 but rarely. 



Equisetum arvense L. var. nemorosum Braun. 107. Fir-woods 

 above Golspie. 



Isoetes echinospora Durieu. 108.* Loch Mer, Betty Hill ; Loch 

 Fhasgaidh, W. of Talmin, near Tongue. 



Charafragilis Desvaux, var. delicatula Braun. 108. Loch Craisg

SUPPLEMENT TO WELWITSCH'S AFRICAN FUNGI. 



By Annie Lorrain Smith. 



In preparing the enumeration of Welwitsch's African Fungi 

 for the Catalogue of his plants now in course of publication, I have 

 found a few new species not included in the paper, " Fungi Ango- 

 lenses " by Welwitsch and Currey, published in Trans. Linn. Soc. 

 xxvi. pp. 270-294 (1868). These I now propose to describe. I 

 have added notes on three species described in the paper. 



Hexagonia Welwitschii, u. sp. Pileus dimidiate or adnate 

 at the back and circular or oval in form, about 6 x 9 cm., edge 

 rather acute. Tissue bright brown, floccose, firm, 1 to 2 mm. 

 thick, the surface of the pileus golden brown, velvety, zoned with
