Ectostroma developed beneath the epidermis, particularly on 

 the leaves, the young succulent shoots and fruits forming as ash- 

 gray coating of the conidial fructification, commonly on the upper 

 surface of the midrib of the leaf and the surface of the fruits; 

 conidia limoniform, simple, hyaline, 8.5-19 X 5.5-14.5 borne on 

 long di- and trichotomously branched chains, disjunctors com- 

 monly present between the conidia; microconidia not observed; 

 pseudosclerotia developing in the infested capsules, at maturity 

 filling the loculi of the immature fruit with a solid mass of thick- 

 walled, hyaline hyphae, falling to the ground and overwintering. 



Apothecia one or two arising as small fundaments from the 

 outer surface of the pseudosclerotia, reaching a height of .8-3.5 

 cm., cyathoid to patelliform, .2-1.4 cm. in diameter, stipitate; 

 stem smooth, slender, cylindric, tapering downward, reaching a 

 length of .4-3 cm. and a diameter of .5-2 mm.; asci cylindric- 

 clavate, reaching a length of 178-258 m and a diameter of 11- 

 16.5 ;u, 8-spored; spores obliquely 1-seriate, or occasionally ir- 

 regularly arranged, ellipsoid, 5-14 X 9-20 ju; paraphyses filiform 

 slightly swollen above. 



Apothecia in May on overwintering fruits of Rhododendron
