NEW OR NOTEWORTHY FUNGI 221 



terram, Birmingham, Martio, 1914, plagas pallide ochraceo- 

 luteas |-1 cm. lat. efformans. 



The resemblance of the spores, in outhne, to those of Coryneum 

 disciforme and its alHes is very striking. 



247. Eamularia sambucina Sacc. Syll. iv, 197. 



Spots roundish or elliptical, 3-6 mm. diam., palhd, with a 

 narrow dark fuscous border, showing on both sides of the leaf. 

 (Jonidiophores hypophyllous, fasciculate, crowded, short ; conidia 

 cylindrical, shghtly tapering at one end, mostly 1-septate, a few 

 ultimately 3-septate, 22-30 x 3-4 /x. 



On leaflets of Sambucits nigra, abundant, Studley Castle, July. 



248. Eamularia Ari Fautr. in Rev. Mycol. 1892, p. 176. Sacc. 

 Syll. xi, 605. 



Spots small, roundish, scattered or collected in groups, at first 

 orange, then ochreous, and often surrounded by concentric borders 

 of various shades. Conidiophores hypophyllous, conidia oblong, 

 shghtly curved, two or more guttulate, hyaline, at length 1-septate 

 at the middle, 10-17 X 2|-3 [i, more often 12-15 /x long. 



On leaves of Arum ^naculatum, near Conway, old Penmaen- 

 mawr Road (J. W. Elhs) ; Studley ; Berkswell ; Ledbury. March, 

 April. In the Studley specimens the greater part of the spots 

 were crowded into one patch, which when fresh gathered was 

 bright orange, and looked Hke those caused by certain Ure- 

 dines ; the parts of the leaf occupied by the hypha3 were sunken 

 above, swollen below, in that case, but not in the others, which 

 were less crowded. Fautrey's description differs somewhat, but 

 probably denotes the same species. 



249. Trichosporium calcigenum Sacc. Syll. iv. 295. Si^orotri- 

 chum calcigenum Link, Sp. PI. Fung, i, 18. 



Hyphae closely apphed to the substratum, effused, branched, 

 filiform, fuscous-grey. Conidia subglobose, very small, blackish 

 in mass, spreading over and staining the patches of hyphae, about 

 4 /x diam. and dark fuscous when mature. 



On damp white-washed walls, especially in hothouses. Ger- 

 many, Italy. This fungus, agreeing exactly with the characters 

 given, appeared in large quantity, so as to cover and disfigure the 

 whole of a freshly whitewashed damp wall, in a warm plant-house 

 at the Botanic Gardens, Edgbaston, Birmingham, January, 1915. 

 The spores were variable, being often lemon-shaped when pale 

 and immature.

On stems of Conium jjiacidatum at Hereford, in May, 1914, I 

 found this fungus again. The creeping hyphae and the base of the 

 erect ones have only a faint colour, and are narrow and some- 

 times almost without septa for a short distance ; the cells in that 

 part are barrel-shaped and longer than broad. The upper part is 

 branched like Horjiiiscium si)lendens. The cells of this part are 

 about as long as broad and globose-cuboid. When placed in water 

 the whole of this upper part breaks up into sections, each containing 

 4-10 cells (mostly 6 or 7). At first all the cells of each section
