≡Amarrendia oleosa Bougher & T. Lebel. 2002. Austral. Syst. Bot. 15: 514. 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 is derived from the protolog of the present species. The present species of Amanita has an hypogeous habit and was originally described in the genus Amarrendia. | ||||||||||||||||||||||||

basidiospores | from protolog: [n=30] 12.5 - 15 (-16) × (8.5-) 9 - 11 (-11.5) μm., (L' = 13.9 μm; W' = 10.0 μm; Q' = 1.39), hyaline, inamyloid, not dextrinoid, broadly ellipsoid to ellipsoid, mainly axially symmetric, with few very slightly asymmetric; apiculus apparently slightly sublateral to apical and truncate conic (per figure); contents guttulate ("oil drop" type). [Note: Without a range of Q values a sporograph cannot be generated. These spore length measurements (and consequently the Q values) are also incomparable with those of other species treated on this site because the length of the apiculus is included in the length measurements. It appears that not all spore data from paratypes were merged to create the summary prevented above. For example, spores from the atypical collections CSIRO H7627, MEL 2063336, and Syme 1085/00 are dealt with separately in the notes section of the protolog.—ed.] | ||||||||||||||||||||||||
ecology | from protolog: In 7-year-old rehabilitated forest of Eucalyptus marginata, Acacia sp. or in open woodland with E. accedens and Gastrolobium microcarpus (sometimes under the latter) or near sheet rock in open stand of Allocasuarina campestris, Acacia lasiocalyx, and Borya nitida. | ||||||||||||||||||||||||

discussion |
t.b.d. Unfortunately, the specimen from which extant nrITS and nrLSU sequences were derived was the most atypical of the paratypes according to the protolog. Material not singled out as atypical should be sequenced to gain confidence that this taxon is accurately represented by sequence data associated with its name. | ||||||||||||||||||||||||

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.
