Site news 2014

[ back to "Site news" ]

28-31 December 2014

New site not yet accessible by public.  Changes reported do not yet show on public site.

Taxon page name change: Amanita amerivirosa, a provisional name, replaces the temporary code A. sp-bisporigera04.

Updated brief tab: Amanita texasorora.

Updated techtab: Amanita cylindrispora and A. texasorora.


Some time in the early hours of 27 December 2014, the content of this site will be frozen prior to a change of provider for cloud services. Our database, non-database content, software, etc. will be ported during the following hours/days.  At the time when switchover to the new server occurs, we and our users may see some unpredictable behavior at first due to new operational parameters on the new server.  If you experience problems with the site in the last days of 2015 or the early days of 2014, we would appreciate it if you would contact us and inform us of the problems you may be seeing.

23-24 December 2014

Change of section: Amanita lippiae has been discovered to belong in section Vaginatae, and that species' placement in the site hierarchy has been changed to reflect that knowledge.

Updated techtabs: Amanita frostiana, A. pahasapaensis, A. parcivolvata, A. texasorora, A. wellsii, and Limacella subillinita.

22 December 2014

Updated techtab: Amanita sp-C21.

18-21 December 2014

New taxon page: Amanita sp-C21 is apparently a species of section Amanita with clamps found at the bases of basidia.  From the evidence of sequences deposited in GenBank, this species has been mistaken for both A. gemmata and A. pantherina in a range extending at least from British Columbia to the San Francisco Bay Area.

Change of taxon name: Amanita sp-C13 reverts to A. macerisolum.  The temporary code, A. sp-T01, is now represented by many collections with a wide geographic distribution and with a "proposed barcode gene" sequence that has been repeatedly derived from material throughout the range; hence, it is time for it to get a provisional name—Amanita texasorora.

Updated brief tab: Amanita sp-C21.

Updated techtabs: Amanita brunnescens, A. cremeosorora, A. inodora, A. macerisolum, A. mutabilis, A. pantherinoides, A. rhacopus, A. roanokensis, A. sp-C21, A. sp-N61, A. sp-QUE03, A. sp-V01, A. stranella, A. texasorora, and Limacella sp-CMP0152.

Updated techtabs: Amanita albocreata, A. dulciarii, A. flavescens, A. phalloides, A. populiphila, A. porphyria, A. rhacopus, A. roseolamellata, A. sp-C20, A. sp-lavendula02, A. sp-Litten_L-715, A. sp-MN03, A. sp-MN04, A. sp-NM10, A. sp-T01, A. xanthomitra, Limacella illinita var. argillacea, L. myxodictyon, L. sp-L-OR01, and L. sp-L-WA01.

9-15 November 2014

Name changes: The long temporary codes for species of Limacella have become a problem especially when one author's collection numbers become assigned to a temporary code named after another collection number of the same author.  In addition, code numbers were being generated without any consistency of format.  For Limacella we will move to "sp-L-" followed by a geographic code followed by consecutive numbering.  The insertion of "L-" will differentiate such numbers from those used for Amanita temporary codes.  Limacella sp-Kuo-08290201 has become L. sp-L-IL01Amanita sp-N59 is apparently genetically identical with A. xanthomitra; and A. sp-N59 has been merged with the latter page and no longer has a separate existence.

New taxon pages: Amanita sp-OR02 is based on a morphologically and genetically unique specimen of section Vaginatae contributed by Britney Ramsey of Linn County, Oregon.  Two collections originally believed assigned to A. rhacopus and A. populiphila in the field have proven to be genetically distinct.  Data will be accumulated on page with temporary codes A. sp-MN04 and A. sp-MNO3 recpectively.

Updated brief tabs: Amanita sp-OR02, Limacella agricola, and L sp-CMP0152.

Updated techtabs: Amanita cochiseana, A. frostiana, A. homolae, A. muscaria, A. muscaria var. guessowii, A. sp-OR02, A. wellsii, A. xanthomitra, Limacella agricola, L. sp-CMP0152, and L. subillinita.

4-6 November 2014

Merger of taxon pages: The taxon page of Limacella sp-Kuo-08290201 has absorbed the contents of the taxon pages for L. sp-Kuo-07220705 and L. sp-Russell-MO107737; the latter two pages have been deleted.  Taxon pages for L. sp-Kuo-08260501 and L. sp-Kuo-07020702 have been found to be based on material of L. glischra; the data on these two pages has been merged with the existing data on the page for L. glischra.

Updated brief tab: Limacella glischra, L. sp-Burnett-5-xi-1994 and L. sp-Kuo-08290201.

Updated techtabs: Amanita cochiseana, Limacella glischra, L. guttata, L. sp-CMP0152, L. sp-Kuo-08290201, L. sp-L-PAN01, L. sp-Russell-MO107737, L. sp-Tulloss-8-31-94-E, and L. subillinita.

31 October 2014

Duplicate taxon page removed: The temporary code Limacella sp-Williams-10-x-1995 has been deleted.  Morphological and molecular data support the placement of the material formerly treated under the temporary code in L. subillinita.  The page for the temporary code has been deleted.

Updated brief page: Limacella subillinita.

Updated techtabs: Limacella illinita sensu H. V. Sm., L. sp-CMP0152, L. sp-Tulloss-8-31-94-E, and L. subillinita.

Updated techtabs: Amanita rhacopus, A. solitaria, A. sp-N61, and A. variicolor.

20-23 October 2014

New taxon page: New taxon pages has been created for Amanita elongatior, A. magna, and A. pseudofulva, some of Yves Lamoureux's provisional names.  The species are assigned to section Vaginatae in Yves' illustrated description (Lamoureux 2006).

Change of section: Amanita vulpecula is unquestionably a species of section Vaginatae.  In fact it is extremely close to Amanita dulciarii.  The distinctly different spore shape is the only distinguishing character found to date.

Updated techtabs: Amanita albiceps, A. elongatior, A. magna, and A. pseudofulva.

Updated techtabs: Amanita basiana and A. whetstoneae.

28-30 July 2014

Changes in sectional placement: Several taxa that appeared to Dr. Bas and RET to have a basal bulb on the stipe have to be moved from section Amanita to section Vaginatae because the nrLSU sequences from these taxa include the indel typical of section Vaginatae alone in the genus Amanita.  For the moment, we conclude that there is a significant volval cup at the stipe base, which should be researched.

The first of the species to be moved is Amanita basiana, Dr. L. V. Kudzma derived nrLSU from an isotype collection; and there was the tell-tale indel.

Updated brief tab: Amanita basiana and A. sp-57.

23 April 2014

Browser changes disrupt sites: Among things that were not useful to our site, many of the leading browsers have ceased to support a function called "innerhtml" in their most recent releases.  The "innerhtml" function was a means of passing data to a subfunction.  The impact on our site has been noticeable with regard to pages that provide a function other than straightforward presentation of data. For example, the filter on the sequences collection page, stopped displaying little pie charts that showed how much of the data for column in the table was selected for a given filtering. The summary of data on the collection page's statistics tab stopped displaying the numbers of items in the list, etc. It is not difficult to find all locations of the use of "innerhtml" in our code; so our site designer/programmer/master, David Tulloss, is progressing through the necessary corrections.

Updated techtab: Amanita pubescens sensu Coker.

18-22 April 2014

Renaming of taxon page: The taxon formerly called Amanita sp-SD01 has been renamed to honor the region using one of the Native American language names for the the Black Hills.l  The new provisional name is pahasapaensis.

Updated techtabs: Amanita annulalbida, A. austropulchella f. mcalpiniana, and A. sp-SD01.

12 April 2014

Page name change: Because RET is inclined to believe that A. xanthocephala is a Western Australian taxon while A. austropulchella may be a distinct eastern Australian taxon, the name xanthocephala f. mcalpiniana has been replaced with austropulchella f. mcalpiniana.  Further change, such as raising the latter name to species rank is possible.

Updated techtab: Amanita austropulchella f. mcalpiniana.

9-11 April 2014

31 March 2014

New and reintroduced pages: Amanita sp-N59 will be dedicated to another apparently distinct taxon morphologically similar to A. rhacopus.  Continuing studies on the DNA of such taxa also reveals that the original collection on which the temporary code A. sp-V03 was based indeed represents a taxon distinct from A. rhacopus; therefore, this page is reintroduced supported by two collections.

Updated brief tabs: Amanita sp-QUE03 and A. sp-V03.

Updated techtabs: Amanita sp-N59, A. sp-QUE03, and A. sp-V03.
