GENERA HYPOCRELLA AND ASCHERSONIA. 533 



beneath the Hypocrella stroma. There is, in fact, a more 

 or less circular gap in the rind, and the inner, radial 

 hyphae grow through this to form the supposed Hypo- 

 crella. The specimens are certainly not Hypocrella 

 parasitic on a scale insect on the Munkia, and it appears 

 to me that the suggestion already made is the only one 

 which fits the case. 



" Hypocrella ruhiginosa " differs from other species 

 in the character of its hyphae, and in the fact that it is 

 not parasitic on a scale insect. If the spores are perma- 

 nently continuous and multiseptate, as they appear to be, 

 it differs from Hypocrella in that respect also. If the 

 " Hypocrella " is reaUy the ascigerous stage of Munkia, 

 the difference in the conidial stages is extreme.

Myriosporium rufum B. & Br., Jour. Linn. Soc, XIV., 

 p. 88. This is not Asehersonia ; it appeai-s to be a 

 Hyphomycete. 



Asehersonia mellea B. & Br., Jour. Linn. Soc, XIV., p. 89. 



This is a small Crepidotus (not Pleurotus, as suggested in 



Ann. Perad., IV., p. 63), pressed flat on the substratum. 



Spores 5-6 X 3-4[i,.

I have not seen this species, but from the description it 

 is quite evidently not an Asehersonia.

 p. 213. 



It is evident from Koordeis' figure that this species, 

 which has multiseptate spores, is not Asehersonia. Only 

 a minute fragment of the fungus now remains on the tjrpe 

 specimen, but it is clear from the remnant that it is the 

 Microcera very commonly found on Aonidia in the 

 Eastern Tropics. This species has since been named 

 Microcera Fujikuroi by Miyabe and Sawada ; presumably 

 the name Avill now stand as Microcera Henningsii.
