 exposed. 



Hy'mcnophore: the portion which bears the hymenium. 



Hy'pha (pi. hyphae) : one of the elongated cells or filaments of which the

Hyste'rioid: elongate boat-shaped, like one of the group of Hysteriaceae. 



Ini'bricate: overlapping like shingles. 



Imperfect fungi: those fruiting stages of fungi which precede the form 

 that represents the final stage in the life-cycle of the species.
