Art. VII. A brief Notice of several Species of Epiphyllous Fungi 

 •which have been observed in the Neighbourhood of Oxford^ and 

 have not been hitherto generally knoxvn to occur in Britain, By 

 Mr. William Baxter, A.L.S., Curator of the Botanic Garden 

 at Oxford. 



Amongst many epiphyllous fungi, which I have observed 

 in the neighbourhood of Oxford, the following are, I believe, 

 new to the British cryptogamic flora. 



Dothidea Heraclhi, Fries Syst. Mycol. v. 2. pt. 2. p. 556. 

 Parasitical on the under side of the leaves of i/eracl^w??i 

 S'phondylium L. — D. Geranii, Fries Syst. Mycol. v. 2. pt. 2. 

 p. 558. ; Loudon's Hort. Brit. p. 458. On the upper surface 

 of the leaves of Geranium rotundifolium L, Summer and 

 autumn, common. — D. i^raxini. Fries Syst. Mycol. v. 2. 

 pt. 2. p. 561. On the under surface of the leaves of JPraxinus 

 excelsior L. In the autumn, not common. Shotover plant- 

 ations. Oct. 2. 1826. — D. Potentillae, Fries Syst. Mycol. v. 2. 

 pt. 2. p. 563. On the leaves of Potentilla reptans Z. 



Asteroma Prunellce, Purton's MSS. Baxter's Stirpes 

 Cryptogamse Oxonienses, fasc. 2. n. 79. ; Loudon's Hortus 

 Britannicus, p. 459. On the leaves and stems of Prunella 

 vulgaris L. in the spring and summer. In damp shady 

 places in Bagley Wood, and on Shotover Hill. This very dis- 

 tinct and beautiful species of Asteroma was first discovered by 

 Mr. John Haines, of the RadclifFe Library, who pointed it 

 out to me in February, 1824. 



[** My much lamented friend, the late Thomas Purton, Esq., 

 of Alcester, Warwickshire, an excellent botanist, and author 

 of the Midland Flora, so often referred to in this work, named 

 it A. PrwiMcc. It is by no means uncommon in Bagley 

 Wood, principally upon such plants of the Prunella as grow 

 in moist places, or on the margins of rills, &c.." (Mr. Baxter, 

 in No. xvii., for December, 1833, of his Illustrations of British 

 Flowering Plants, in the text appertaining to Prunella vul- 

 garis Z/. — See a communication on British plants by the late 

 Mr. Purton in this Magazine (VI. 57.). J- ^0
