longer than the asci, tips not thickened but agglutinated

Sticiis lecanora (Schum.), var. pyri, B. & Br., Ann. Nat. 

 Hist., n. 1624, t. 11, fig. 7. 



Propolis pyri, Phil., Brit. Disc, p. 375. 



On bark of pear tree. 



Type specimen examined, also specimen in Phil., Elv. Brit., 

 n. 148. 



A distinct species, characterised by the purple-black disc 

 and purple mucilage at the tips of the paraphyses. Hypo- 

 thecium pale brown. 



Phillips says the spores are " slightly tinted brown." I 

 have not observed this coloration in the specimens examined, 

 nevertheless this may be the condition at maturity. The 

 present species departs from the usual type in having an 

 obscure disc, yet it agrees with the genus in all essential 

 morphological points.

Spores fusiform. 



Ocellaria punctiformis. Sacc, Syll., n. 2700. 



Gregarious, immersed, urceolate, mostly orbicular, margin 

 more or less irregularly torn, raised, up to \ mm. across, 

 hymenium dingy reddish-brown (when dry and old) ; asci 

 cylindric-clavate, apex obtuse, 8-spored; spores narrowly 

 fusiform, hyaline, continuous, 7-9 x 2 fx; paraphyses slender, 

 tips clavate. 



Stictis punctiformis, Pers., Syn., p. 674 ; Phil., Brit. Disc, 

 p. 386. 



On dead willow wood. 



Specimen in Herb. Kew, named by Persoon, examined. 



Gregarious, disc depressed and surrounded by a raised 

 margin, formed in the first instance by the excipulum proper 

 to which the bark is connate ; very frequently the bark 

 falls away, leaving only the proper margin of the fungus, 

 which then resembles a Stictis, from which the present differs 

 in the short spores. 



Ocellaria chrysophaea. Quel. 

 Scattered, erumpent, orbicular ; hymenium concave, reddish; 

 border rather thickened, golden-yellow ; asci cylindraceo-cla-
