≡Venenarius margaritus Murrill. 1945a. Mycologia 37: 270. The editors of this site owe a great debt to Dr. Cornelis Bas whose famous cigar box files of Amanita nomenclatural information gathered over three or more decades were made available to RET for computerization and make up the lion's share of the nomenclatural information presented on this site. | ||||||||||||||||||||

| intro |
The following text may make multiple use of each data field. The field may contain magenta text presenting data from a type study and/or revision of other original material cited in the protolog of the present taxon. Macroscopic descriptions in magenta are a combination of data from the protolog and additional observations made on the exiccata during revision of the cited original material. The same field may also contain black text, which is data from a revision of the present taxon (including non-type material and/or material not cited in the protolog). Paragraphs of black text will be labeled if further subdivision of this text is appropriate. Olive text indicates a specimen that has not been thoroughly examined (for example, for microscopic details) and marks other places in the text where data is missing or uncertain. The following material not directly from the protolog of the present taxon and not cited as the work of another author is based on original research of R. E. Tulloss. | ||||||||||||||||||||

| discussion |
The following general observations were made by RET (vi.1990): The two specimens in the type collection are in very bad condition and have been extensively attacked by insects. The lamella trama of both specimens appears to be thoroughly collapsed. The following sporograph comparisons are presented to compare the spore size and shape of the presents with spore size and shape of other white or whitish taxa having cylindric to bacilliform spores and having been considered at one time to be assignable to section Phalloideae. Given the comparison of sporographs, the present taxon appears most similar in spore size and shape to A. virosiformis (presently thought to belong in sect. Phalloideae), while A. cylindrisporiformis has spores more similar to those A. cylindrispora (sect. Lepidella). | ||||||||||||||||||||

Spore data sets and their composite
Each spore data set is intended to comprise a set of measurements from a single specimen made by a single observer; and explanations prepared for this site talk about specimen-observer pairs associated with each data set. Combining more data into a single data set is non-optimal because it obscures observer differences (which may be valuable for instructional purposes, for example) and may obscure instances in which a single collection inadvertently contains a mixture of taxa.
