NEW OR NOTEWORTHY FUNGI. 131 



(Ecidium on Hieracmm which is sometimes assigned to CE. pren- 

 anthis differs from that, according to my specimens, in the 

 possession of a peridium, but whether that is true of Cooke's 

 specimens (/. c.) I do not know. The (Ecidium on Lactuca has a 

 small unbordered opening; as Persoon says — "ore connivente, 

 integro." 



MORTIERELLA Coemans (1863). 



Mucorine. Mycelium slender, dichotomous and anastomosing. 

 Fertile hyphfe erect, pellucid, simple, or branched above or below ; 

 branches terminated in a single spherical sporangium, which has 

 a very diffluent non-incrusted membrane, and is without columella, 

 Endospores oval or roundish, occasionally angular or fusiform. In 

 some species chlamydospores (of two kinds) and zygospores are 

 also known. 



34. Morlierella Candelabrum Van Tiegh. Eech. sur les Muc. 

 p. 94, pi. 54, figs. 99—102 (1873) ; Bainier, Etude sur les Muc. 

 p. 104 (1882). Var. minor mihi. Fertile stem branched from 

 near the base with long ascending subulate branches after the 

 fashion of a candelabrum. Spores perfectly round, smooth, hyaline, 

 10-12 fi diam. (Tab. 256, fig. 1). 



On rotten wood, Sutton (Wk.), September. Height l-5th to 

 l-3rd mm. Bainier describes the species as reaching 2 mm. in 

 height, and the spores as oval, 6-3 //. x 2-1 i^^. ; his specimens were 

 on dead flies and on agarics. Van Tieghem describes it as 1 mm. 

 high ; spores 4-10 i^t. (average 6 |M,), round ; on excrement. The 

 form here described differs in its much smaller size and much 

 larger spores. 



35. Eutypa velutina (Wall.) Sacc. Fung. Ven. iv. 16 (1875); 

 Fung. Ital. 472 (1878); Syll. Pyr. i. 176 (1882); Phill. et Plow. 

 Grevillea, xiii. 75 (1885). — SpJucria velutina Wallr. Fl. Crypt, iv. 

 844 (1833). 



On Acer campestre, Marston Green (Wk.), May. Whether my 

 specimens are those referred to by Messrs. Phillips and Plowright 

 [1. c.) I do not know. 



86. Ceratostoniella vestita, Sacc, Mich. i. 870 (1878); Fung. 

 Ital. 344 (1878); Syll. Pyr. i. 408 (1882) Var. varvicensis mihi. 



Perithecia scattered, often two more or less connate, sub- 

 superficial, black, globular, ^-^ mm. diam ; loosely clothed with 

 long brownish septate hairs, 200-300 /x x 4-5 ^a ; extended into 

 a naked black shining curved cylindrical ostiolum, which equals or 

 often exceeds the perithecium, and is conical and longitudinally 

 quadrisulcate at the apex ; asci cylindrical 50-55 /x x 4 )x, obtuse, 

 shortly stipitate, 8-spored; sporidia obliquely uniseriate, ellipsoidal, 

 8-9 f/. X 8^-4 fjL, hyaline. 



On decayed wood, Sutton (Wk.), October, in company with 

 Diplococcium spicatum [q. v.). Differs from the type in the longer 

 quadrisulcate ostiolum and the larger sporidia ; the perithecium 

 is at first semi-immersed, but at last becomes completely super- 

 ficial.
