Observations — This species and //. schulzeri are exceedingly simi- 

 lar to each other, but we believe they are distinct. We have a critical 



account of //. schulzeri from England (Orton, 1960, p. 264) which 

 agrees that //. schulzeri does not have a stipe 1 that becomes blackish 

 nor gills which become brownish drab ("hair brown"). There also ap- 

 pears to be a distinct difference in the hymenophoral brama, the hy- 

 phae being more parallel in H. schulzeri and more interwoven in //. 

 hymenocephalus. According to our studies both lack clamp connec- 

 tions. For the Trinidad collection having clamped hyphae and de- 

 scribed by Dennis (1953), see H. dennisianus. II. schulzeri sensu Jos- 

 serand we consider to be the same as H. decepiivus.
