Earle : Some Florida Fungi 123 



I note the following characters from the Florida specimens : 



Causing wart-like, often confluent distortions, I cm. in diam- 

 eter : perithecia densely gregarious, innate-erumpent, black, car- 

 bonaceous, often flexed or irregular from crowding, lips somewhat 

 widely open, about I x ^ mm.: conidia-bearing perithecia smaller 



and less distinctly hysteriform : conidia obovate, continuous, granu- 

 lar, hyaline to brownish, 28-30 x 12 fi : conidiophores about 

 20 x 4 //, straight and stiff: asci nearly sessile, broadly oval, thin 

 walled, 80-120 x 20-25 fi y paraphyses numerous, crowded, simple, 

 the tips forming a brownish epithecium, about 120 X 3 t l : asco- 

 spores inordinate or partially biserrate, oval, continuous, minutely 

 granular, light brown, closely packed in the ascus and often some-

Lembosia cam 



Epiphyllous : spots orbicular, nearly black with a narrow 

 brownish border, 3-5 mm., in diameter, rarely confluent : perithecia 

 thickly scattered over the central portion of the spot, often by 

 confluence forming considerable crusts, single perithecia elongate, 

 straight or slightly flexed, rather flat not prominent, lips somewhat 

 widely open, averaging about 500 x too }i, surrounded by a 

 rather scanty subiculum of slender occasionally septata, flexuous, 

 anastamosing, brown threads about 3 /*, in diameter, the subicu- 

 lum reaching 100 p $ in width : asci broadly oval, thin-walled, 8- 

 spored, about 25 x 20 p : ascospores inordinate, oval, slightly 

 curved, about equally uniseptate, conspicuously constricted, ends 

 subacute, faintly olivaceous, becoming light brown at full maturity,- 



about 18x6 p.

CampJiora officinalis, Florida. P. H. Rolfs, 



rium ? carbonaceum 



Amphigenous but mostly epiphyllous, not spotting or dis- 

 coloring the leaf: perithecia irregularly scattered, large, about 

 1 mm., black, shining, carbonaceous, not distinctly parenchyma- 

 tous, scutellate, central fertile portion strongly elevated, with a 

 minute, central papillate imperforate osteolum, bordered by a flat 

 sterile margin, often confluent, two or three together : sporules nu- 

 merous, irregularly oval, yellowish, continuous, rather thick-walled, 



6-20

On unknown living coriaceous leaf. Lemon City, Fla., Feb., 

 1898. P. H. Rolfs, no. 39. 



This conspicuous fungus is doubtless the immature stage of 

 some species of the Microthyriaceae. It has little in common with 

 the minute membranous species usually referred to Lcptothyrium.
