Polyporus umbellatus Fr. 
On the ground, in a wood on the north bank of River Hay 
on the N. side of footpath, a little to the E. of the gully oy of 
the Wittonstone field, Longwitton, 26 August, 1904. ; Tt wae 
also found by me, at the same place several years ago, when | 
failed to identify it. Although I have often looked for it since 
at the same place, I have never seen it again until last Auoyst 
These are the only two specimens I have ever met with, It 
grows in a cluster of roundish outline reminding one at the first 
glance of Sparassis crispa. It is very brittle, and very soon 
perishes. On each occasion I sent the specimen away by post, 
the day after 1 found it, and each time it arrived like a handfyl 
of wet sawdust. 
The pileoli are rather scaly, very much waved, and thin; the 
pores extend all down the stem, and are variable in form, here 
and there elongated. 
The spores have much the same outline as that of a grain of 
wheat.
