any perithecia. Fries, who was no doubt only guessing from Schwei- 

 nitz' figure, started the story that it is the conidial state of Xylaria 

 corniformis, and while there is not the slightest possibility of that 

 being true, it was accepted and published by Ellis in his N. A. Pyren- 

 omycetes as "an abortive form" of Xylaria corniformis. The plant 

 is not rare with us, and I have it also from Africa, but I do not know 

 it in Europe. There have been two other bulls made in connection 

 with it, both Peck and Montagne having discovered that it was a 

 "new species" of Thelephora (sic). Peck called it Thelephora rosella, 

 and Montagne (from South America), Thelephora liliputiana. 



That Isaria flabelliformis is the conidial state of a Xylaria is 

 possible, even probable, but the ascigerous form is not known, at least 

 as to specimens, and those who find it growing should mark the 

 place and leave it, and if it develops a later stage, I should be very 

 glad to receive specimens. 



SPORES OF CALVATIA VERSISPORA (Fig. 750). "With 

 regard to Calvatia versispora, the spores are very irregular, and 

 some of them are more or less fusiform, as I have drawn, but I

should not tall such "apiculate." None of the spores seem to have 

 a definite, regular, apiculus such as one gets in many Lycoperdons, 

 but some of them appear to have a blunt stalk, as I have indicated. 

 Are not the spores immature? They appear so to me, and distorted 

 by mutual pressure. The very large, irregular, yellowish cells, of 

 which 1 have drawn three (two apparently attached), are not spores 

 but seem to be detached, sterile cells." Letter from Miss E. M. 

 Wakefield. 



XT C fJ V xT ia versis P ra is a Japanese species. Compare Letter 

 No. 56, Note 247, Figure 707. The plant was published as Calvatia 

 versipora I presume Calvatia versispora would better indicate 

 the idea (though both are pidgin Latin), and if those nomenclatural 

 sts who so strenuously insist on the perpetuation of all original 

 blunders will kindly overlook it. I would wish to correct it.
