the exoperidium reflexed, the fleshy layer gone, so as to give the endoperidium 

 a subpedicellate effect. Geaster quadrifidus is Geaster coronatus, a large speci- 

 men, and a rare plant in the United States. Geaster minimus is the type of tliis 

 well-known species; Geaster rufescens is as we now know it. Geaster hygro- 

 metricus and Geaster fibrillosus are both the former. 



Bovista gigantea is wrong. It has lilac spores, and is Calvatia lilacina. 

 Bovista craniiforrnis is Calvatia craniiformis, as now known. Professor Morgan 

 told me that before adopting the specific name he tent a plant to Philadelphia 

 and had it compared with Schweinitz's type. Bovista uigrescens is Bovista Pila. 

 Schweinitz could hardly have been expected to distinguish between these two 

 species, as it is solely a microscopic spore difference. Bovista nigrescens is not 

 known to occur in the United States. Bovista plumbea has the general, external 

 appearance of being correct, and I think I so passed it on my previous visit. 

 The microscope shows, however, that it has entirely different capillitium and 

 spores, and is an immature Catastoma, the same species as the next. Bovista 

 Candida is Catastoma circumscissum, as now known. This plant, and its larger- 

 spored form, have been taken to be a new species at least a dozen limes, and in- 

 cluding the juggled ones, has probably twenty different names. Schweinitz's 

 name, Candida, is the earliest one I have thus far succeeded in unearthing. 1 



Lycoperdon pratense is not in good condition, but is, I think, old decorti- 

 cated specimen of Lycoperdon cruciatum. Lycoperdon echinatum, from its white 

 spines, is Lycoperdon pulcherrimum. Lycoperdon piriforme is correct, and also 

 Lycoperdon quercinum is a form of it. Lycoperdon excipuliforme and Lycoper- 

 don perlatum are both Lycoperdou gemmatum. L^operdon utriforme is too 

 fragmentary to name. 



Tylostoma brumale and Tylostoma squamosum. It would be hazardous to 

 pass an opinion on such specimens as these. The former is too large to be typi- 

 cal of the European plant (mammosum). 



The remainder of Schweinitz's Gastromycetes are all Myxomycetes, hence 

 do not fall in my line of work. 



DO YOU KNOW A FETID PUFF BALL? I am told by Rev. J. Rick 

 (now in Brazil) that he once collected in Holland a Lycoperdon that was 

 truly fetid when fresh. We know that Bonorden described a Lycoperdon 

 foetidum, but he found so many new species that no one else ever found that 

 we have not placed much stress on any of his "finds." Rev. Rick's observations, 

 however, can be relied upon, and I hope mycologists in Europe will be on 

 the lookout for a fetid puff ball. 



LATIN TERMS. In our work on the Nidulariaceae we used several Latin 

 words where the English would have been better. Thus, "funiciiliis" for 

 funicule, "tunica" for tunic. We did not do this to show the little Latin we 

 may know, as we do not question that we show how little that is quite fre- 

 quently without intention. We wrote the article at Paris, out of touch with 

 English dictionaries and our reference works (Tulasne and Saccardo) were 

 in Latin. We did not know what the corresponding English words were for 

 these terms, nor in fact if there were any. 



THE "CAPILLITIUM" OF NIDULARIACEAE.- None of the Nidulariaceae 

 have capillitium, although it has been a tradition of the subject ever since De 

 Toni mis-read Tulasne's account and defined Cyathus as having "sporae filamen- 

 tis nnmixtae". Dr. H611os on Plate 28 shows spores and "capillitium" of several 

 species. What he takes for capillitium is the hyaline, nodular strands of the 

 fumculus, and have the same relation to capillitium that a kite string has to the 

 frame work of a kite. You must not believe everything you see in print, nor 

 all the pictures, even if they are put forth as "science".
