Where forming towards the margin, the tubes are very shal- 
low, as stated by the authors of the species, but truly porose 
there and so greatly elongated in the older portion of the 
fructification that this species is certainly a Poria. Collectors 
should look for it among their collections which have been 
roughly classified as Poria, as a fleshy Poria becoming black 
where bruised and drying nearly black, having large colored 
spores, tubes 3 mm. long and 1-3 toa mm. The paler color 
of the surface of the type is probably due to a mould which 
is present. The description of M. spissus and collector’s 
reference to it, published in ‘Grevillea,’ were not sufficient for 
positive location of the cotype in Curtis Herb.; I am indebted 
to Miss Wakefield for critical notes and to the Director of 
Kew Herbarium for a fragment of the type, which have made 
confirmation of the беген possible.
