Appears to be distinguishable from true fumigatus by larger 

 size, and less rufescent color on the upper surface. Although its 

 range can not be fully worked out from the scanty material avail- 

 able, this form probably represents fumigatus on the mainland of 

 Asia, thus restricting the latter to the islands of Japan.
