Caldesiella Duemmeri, Wakefield. 
Fungus late effusus, tenuissimus, tomentosus, fusco-ferrugino- 
i 
sus, margina indeterminato concoiore. Aculei minuti, nudo 
ae 
textae, septato-nodosae, 2-5 x 3 u (basales ad 5 #) diametro. 
Tropica Arrica. Uganda: Kipayo; on a rotten log in 
forest, May, 1914, Diimmer 635. 
Distinguished from known species of Caldesiella by the very 
small spores. The general colour of the hyménium matches 
Ridgway’s ‘‘ Raw Umber ”’ (17 m).

The receipt from Uganda of material of this species in an 
older stage has led to the establishment of the above haw 
whic i 
castanea was founded, is in a young state, and more brightly 
provect above the brown setae, forming a compact, waxy 
ymenium, which is cracked into small areas when dry. In this

the peculiar structure of this species. rom» the description 
it seems probable that D. velutina is identical with the present 
ant. D. Raimundoi is said to be more brightly coloured, but 
48 spores were not found it is possible that this is again a 
question of age, as in the case of H. custanea. Duportella is 
ymenium above the setae, but it seems preferable on the whole 
to retain it in Hymenochaete.
