Remarks (internal):Dring (1964) referred to this a collection from southern Nigeria, Old Calabar, on soil, 10 June 1910, known to him only from eggs and a water colour sketch by the collector. The type from Sao Thome is also represented at Kew only by a dried egg.
Though nothing is said of the structure of the arms their very narrowness surely points to a regularly tubular structure so that, if a Clathrus, the species would fall with the Clathrella series, where its red colour and apparent lack of glebifers are out of place. There was no indication of a stipe but a short one could be concealed in the volva and the possibility cannot be excluded. Inevitably the colour and stature remind one of Co/us and it may be no accident that other material referred to C. hirudinosus was forwarded by the same collector from the same locality at Old Calabar. An affinity with C. pusillus seems therefore likely for C. parvulus. Fig. 27B-C.
