186 Tracy and Earle : Some new Fungi 



numerous parallel, simple, fuscous threads about 10-20 x 2-3 ft ; 

 asci oval, about 20 x 16 /i ; ascospores eight, inordinate, oblong, 

 ends obtuse, nearly equally uniseptate, subhyaline (young) about 



8-10 x 4 p. 



On living leaves of Ilex sp., Longboat Key, Fla., April 27, 1900, 



S. M. Tracy, no. 6570. 



This differs from any of the described species on Ilex in the 



numerous very short ascomata and especially in the character of 



the subiculum. 



Lembosia cactorum sp. nov. 



Scattered without definite spots ; ascomata black, shining, 

 straight, distinct not anastamosing or forking, rather thick or sub- 

 elevated, with the aspect of a small Hysterium, 200-500 x 100- 

 150/4, ends obtuse, lips connivent or slightly parted, subiculum of 

 agglutinated and anastomosing threads 2-4 /j. in diameter, and usu- 

 ally extending to 20-40 a or more, epithecium well developed ; 

 asci oval, 25-30 x 16-20 fi : ascospores eight, narrowly ovate, in- 

 ordinate, unequally uniseptate, ends obtuse, hyaline (?) about 

 12 x 4 fJt. 







On Opuntia vulgaris, Palma Sola, Fla., May 2, 1900, S. M. 

 Tracy, no. 6592. 



This species departs somewhat widely from the usual lembosia 

 type. The ascoma is better developed and firmer. This with the 

 presence of an epithecium points to a relationship with the true 

 Hysteriaceae. 



The color of the spores is not a reliable character in this group. 

 They are usually long hyaline or faintly tinted, only becoming dark 

 (usually brownish) with age. 



Acanthostigma conocarpi sp. nov. 



Amphigenous but mostly hypophyllous, scattered, without 

 spots ; perithecia minute, subconic, brown, of thin, delicate, ob- 

 scurely cellular parenchyma, 75-90//, clothed with scattered, erect, 

 rigid, entire, dark fuscous, opake bristles 40-50 p long, base about 

 4 fA wide, tapering upward to an acute point ; asci oblong or slightly 

 obovate, short-pedicillate, about 40 x 10//; paraphyses thread- 

 like, slightly exceeding the asci ; ascospores distichous, cylindric- 

 clavate, anterior end obtuse, posterior subacute, twice septate, not 

 constricted, hyaline, about 12x3/*.
