26 FUNC.I PARASITIC UPON ALEYRODES CITRI. 



The ascus stage is described in Saccardo's Sylloge Fungorum 34 thus : 

 Sphacrostilbc coccophila Tul. Carp. III., 105. Peritheciis permultis supra et prope 

 stromata conidiophora nascentibus, minimis globosis, obtusis, brevissime papillatis, 

 glaberrimis, nitide rubris, saepe 4-5 sociatis, senio collabentibus; ascis linearibus, 

 60-80X6J/2; sporidiis oblique monostichis, ovatis, 10X5, 1-septatis, subhyalinis, leniter 

 constrictis. Stat. conid. Microccra coccophila Desm. Stromate e crusta coccornm 

 solitarie oriundo, crasse teretiusculo, obtuso. rnbro 2 mill, alt.; conidiis lineari- 

 lanceolatis 4-6 locularibus, 65X6 subhyalinis. 



In 1892, Ellis and Everhart-' 55 in "Xorth American Pyrenomycetes" gave 

 nearly the same description in English, and reported this fungus on a speci- 

 men of Alnus scrrulata collected in Pennsylvania, adding: 



The conidial stage (Microccra coccophila Dcsm.) which has been sent from 

 Florida by Dr. Martin and collected in Carolina by Ravenel (F. Am. 286), has stroma 

 arising from various species of dead bark-lice. It is red, obtuse and about 2 mm. 

 high. The conidia are linear lanceolate, 5-7 septate and 56-65X5-6 microns, nearly 

 hyaline. 



D. McAlpine 36 in describing the con- 

 /ft'''Vf\ idial stage of this species in Australia 



/i la 1ft gives the measurements of the conidia 



as 75103X5^8^ microns. Meas- 

 urements made of a number of Florida 

 specimens from different localities gave 



Fig. 15. Conidia. 



70112X3.56 microns. Measurements x 200. 

 of the perfect stage from Florida specimens were as 

 follows: Perithecia 350 390 long by 300 microns 

 thick. Divisions of perithecial wall 6 10 microns. 

 Asci, 7098X812 microns. Spores 1218X79 

 microns. 



HISTORY. 



!'!_'. 11. >i>orodochinm, or 



*2K2S2S^ f This fungus has been found in nearly every coun- 

 try in the world. In 1892, M. C. Cooke 37 spoke of it 

 as common in Europe and as a well-known parasite on dead Coccus. In 

 the same year it was reported from Jamaica by T. D. A. Cockerell. 38 In 

 1894, Henry Tryon 39 reported it on the long scale, the red scale and the 

 circular black scale in Queensland, Australia. In 1897, it was reported 

 by P. H. Rolfs 40 as a parasite of the San Jose Scale, Aspidiotns pcrniciosus 

 Comst In 1899, it was reported by I). McAlpine 41 on Aspidiotns anrantii
