' Some Notes upon the Cryptogamic Portion of the Plants collected 

 in Portugal, 1842 — 50. By Dr. Fried. Welwitsch ; the 

 Fungi by the Rev. M. J. Berkeley, M.A., F.L.S., &c., &c., &c. 

 London : William Pamplin, 45, Frith Street, Soho Square. 

 1853.' 



This little hroghure is printed for the use of the subscribers to the 

 collections of Portuguese plants made by Dr. Welwitsch. It contains 

 a list of seventy-three species of Fungi ; each species being accompa- 

 nied by a note as to the habitat, plant on which it is parasitic, &c. 

 Twelve of the species are new to science, and we have therefore 

 extracted their characters, thinking they would be useful to the cryp- 

 togamic botanists of this country. 



" Phyllosticta h(Ematocycla, Welw. No. 4. Maculis latissirais pal- 

 lidis rufo-cinctis ; peritheciis parcis submarginalibus ; sporis oblongo 

 subclavatis ; sporophoris amplis. On the leaves of Phormium tenax; 

 Lisbon, Jan. 1843. Obs. — Spots irregular, several inches long, occu- 

 pying almost the whole breadth of the leaf, surrounded by a rich 

 rufous toothed or entire border. Perithecia rare, mostly marginal. 

 Spores hyaline oblongo-subclavate. Sporophores clavate, 



" Dothidea durissima. Pustulis elevatis compactis; ostiolis cellu- 

 larum exasperatis ; sporidiis fusiformibus uni-triseptatis. Welw. No. 

 12. On branches of Qiiercus pseudococcifer, Webb ; near Piedale, 

 on the left bank of the Tagus. Ois.— Pustules raised very hard and 

 compact about a line broad, rough with the prominent ostiola. Asci 

 clavate ; sporidia fusiform, at first uniseptate, but eventually a septum 

 is formed in either of the divisions ; each endochrome contains a large 

 nucleus. I have seen only two sporidia in each ascus. 



" Gymnosporium inqiiinans. Soris elongatis aterrimis ; sporis lae- 

 vibus obscuris ovatis vel subellipticis. Welw. No. 20. On dead stems 

 of Arundo Donax, near Lumiar. Obs. — Forming linear elongated at 

 length confluent sori, consisting of dark even ovate or subelliptic 

 spores, which spring from short, sometimes forked threads. This 

 species is common, but I believe it is undescribed. 



" Phyllosticta Ceratoniee. Maculis nigro limitatis irregularibus ; 

 sporis minutis anguste ellipticis hyalinis. Welw. No. 37. On leaves 

 of Ceratonia siliqua, in the Serra of Arrabida. Obs. — Spots very 

 irregular, often marginal, surrounded by a raised dark line, gray or 

 dusky. Spores minute elliptic narrow hyaline.
