adhere by their summits being apparently held together 

 by a brownish " gelatina hymenia," and at intervals 

 occur some which are brown throughout their whole 

 length, and non-septate. These deserve more careful

 to convey from the subhymenial tissue the brown 

 " gelatina hymenia " alluded to above.
