In Fragmente zur Mykologie, Mitt. XIV., p. 31 (368), von 

 Hohnel records for Ceylon Nectria flocculenta, which he found 

 in the type specimen of Nectria stenospora B. & Br. in Herb. 

 Kew, and suggests that it is identical with Nectria flavolanata 

 B. & Br. The specimens in Herb. Kew in the type of N. 

 stenospora which are marked N. flocculenta by von Hohnel are 

 identical in perithecial wall and hairs with N. flavolanata, but 

 their spores are oval, thin-walled, 9-10 X 3-5 [i. Elsewhere, 

 von Hohnel gives 9-10 X 3-4 [i. for the spores of N. luteopilosa 

 Zimm., which he regards as identical with N. flocculenta v. H. 



It would appear from the above that Nectria flocculenta 

 differs from Nectria flavolanata in its smaller spores, but 

 recent gatherings tend to show that the more correct inter- 

 pretation is that the spores are subject to considerable varia- 

 tion in size. In No. 2151 in Herb. Peradeniya the perithecia 

 are those of N. flavolanata, though the hairs are poorly deve- 

 loped, but the spores are thin-walled, obscurely striate, 10-13 

 X 3-3*5 \i.. In another gathering, No. 4279, in Herb. Pera- 

 deniya, the perithecia have a well-developed covering of hairs 

 agreeing exactly with N. flavolanata, but while one slide 

 shows oval, striate spores, 13-17 X 6-8 {x, another shows 

 thin-walled, narrow-oval, or oblong-oval, spores, 10-13 X 

 3-3*5 \x. These smaller, thin-walled spores appear to be 

 quite mature. 



It may be noted that the measurements of these thin-walled 

 spores agree with those given by Zimmermann for the conidial 

 [Leptotrichum) stage of N. luteopilosa. In the present case, 

 however, they are undoubtedly ascospores. 



Forms of Nectria flavolanata, in which the indumentum is 

 poorly developed, are of frequent occurrence. In some of 

 these a few short hyphse of the typical character are present ; 

 in others there is only a yellow incrustation on the wall of the 

 perithecium. 



Nectria coccinea Fr. 



This was recorded for Ceylon by Berkeley and Broome in 

 Fungi of Ceylon, No. 1009, from Thwaites 48. Both in Herb. 

 Kew and Herb. Peradeniya the specimens are Megalonectria 

 pseudotricha (Schw.) Speg.
