to flabelliform pileus, covered on the upper surface with a dense, 

 spongy t omentum. The hymenial folds on the under surface of 

 the pileus are broad and warted. 



8. Pleurotus applicatus, Batsch. 



A small sessile agaric is at times not uncommonly met with 

 in the bush around Durban growing on wood lying on the ground 

 and is referred to Pleurotus applicatus, Batsch. It has not pre- 

 viously been recorded from South Africa, and the following brief 

 description is given to aid in its recognition. 



Cap sessile, imbricate, shell shaped, 0.4 cm. to 1.2 cm. across, 

 gray to bluish-gray or blackish, glabrous to pruinose or finely 

 hairy; gills gray, radiating, distant, broad in proportion to size 

 of plant. The upper layer of the pileus is gelatinous, and dried 

 plants readily revive if placed in water. 



THE FLORA OF ISIPINGO.

Isipingo is a well-known seaside resort about one hour's 

 journey from Durban. Isipingo Beach is over a mile distant from 

 the village at the station. 



The greater part of the shore, especially on the right-hand 

 side of the Lagoon, is very rocky. Large and small pools abound 

 among the rocks, and their sides are covered with brightly coloured 

 sea-weeds and sea-anemones. The rocks, which are only partially 

 exposed during very low tides, are completely covered with bril- 

 liantly coloured sea-weeds. Delicately hued sea-anemones in 

 crevices, pools and on ledges, and large and small sea-urchins, 

 whose shells are covered with long stiff black bristles, are to be 

 found all over the rocks. 



The sea-weeds noted have been identified as far as possible 

 by the aid of Miss Frank's collection in the Natal Herbarium. 

 Over seventy different kinds were collected, and less than half 

 have been identified : these latter are given in the following list. 

 Amphiroa anceps, Apjohnia rugulosa, Brack i/claria marginata, 

 Bryopsis flanagani, B. setacea, Caulerpa ligulata, Chaetomorpha
