Corrected spelling: The epithet "fibrilosa" was incorrectly spelled in its protolog except in the caption of a figure.  The correct spelling is adopted on this site.  We find no reason supportive of the idea that A. fibrillosa is based on an aged specimen of A. strobilaceovolvata as proposed by Gilbert (1941) and move A. fibrillosa from listing in sect. Caesareae to listing in sect. Vaginatae.

Taxon moved: Amanita robusta Beeli was misplaced in sect. Caesareae.  Its protolog includes an illustration showing a stipe that is not totally elongating and describes the partial veil as cortina-like.  It has been moved to Amanita [section Amanita subsection Amanita] series Pudicae because of its morphological similarity to A. pudica, which also bears a saccate volva.

November 10 2011

Data field name change for Limacella techtabs: We have proposed that the gluten layer in Limacella is the evolutionary predecessor to the universal veil in Amanita.  We continue to think that this is probably the case; however, the gluten layer has its own unique characters and describing it in the "universal veil" data field of this site has begun to seem inappropriate...sort of forcing a triangular peg into a round hole.  Hence, we have introduced a new data field that will appear on techtabs for taxa in Limacella—"gluten layer"—which will replace the appearance of the "universal veil" data field on those techtabs.  We now have to edit out references to the "universal veil" in existing descriptions of the pileus and stipe and replace the phrase with "gluten layer."  Sometimes, more complex editing is required.  This will take a little time.  We have completed preliminary edits for the brief and technical tabs of the species of sect. Amanitellae.

Updated techtabs: Amanita cokeri, Limacella delicata, L. myxodictyon, and L. roseola.

Early this morning (eastern U.S. time) the number of visits to this site surpassed 18,000 for the present year.  At the same time the total content downloaded to our users in 2011 surpassed 12.62 GB.  We thank all our users for the value they obviously place on "Studies in the Amanitaceae."

Citation of pages has been facilitated by a "cite this page" function that was added in the last week.  Material from this site represents the work of numerous authors and much, otherwise unbpublished, original work of RET.  We have seen cases of this work being used in print and on the web without mention of the source.  This is inappropriate and not in the scientific tradition.  We ask that our users, cite these pages when they use them in support of their own publications.  This is now facilitated by the "cite this page" function which appears on every page in the lower right corner of the blue "page name box" at the top of the page.

Many, many thanks to the attendees at the COMA C. T. Rogerson Memorial Foray over the last weekend.  We still don't know with any certainty the number of Amanita species collected during the foray, but the count is presently well over 40 and expected to get close to 50.  A goodly number of the collections represent undescribed taxa, and several are completely new to us.  Hooray for all the hard-collecting participants.

We extend our thanks to Dr. Elaine Davison who generously sent us images of the fascinating Australian species A. basiorubra and A. fibrillopes.

Updated brief tabs: Amanita basiorubra and A. fibrillopes.

September 2 2011

Today the U.S. team heads to Hebron, Connecticut for the annual COMA (Connecticut-Westchester Mycol. Assoc.) foray weekend.  Over recent days, efforts were made to improve site coverage of provisional taxa that have been collected in eastern Connecticut.  This effort should support a better selection process for retention of samples of both well-known and apparently undescribed taxa during the foray.  The foray area (extending over several Connecticut counties) provides interesting fungal diversity in a region that mixes sites with Canadian Hemlock (Tsuga canadensis) and hardwood forest with forests more typical of the sandy Atlantic Coastal Plain.  Hence, at one foray, one may find "southeastern" species such as A. cylindrispora, A. subolitaria, and A. recutita sensu Coker as well as the beginnings of the great diversity of undescribed taxa in section Vaginatae typical of the boreal and subboreal forests in northeastern North America.

September 1 2011

Over the last few days, we noticed what we thought was a general tendency of spore widths to be (on average) larger in (Grgurinovic 1997) than in other works concerning the same (largely Australian) species.  The apparent problem appeared significant enough so that it affected the range of spore width, the mean spore width, the range of Q, and mean Q.  We have confirmed that there is a problem with this data (sometimes amounting to differences of as much as 2 μm in the value that we would normally take to be the "c" value in a typical range of the "(a-) b - c (-d)"; and we found that spore length data in the same work also is similarly problematic.  As a consequence, we have decided not to supply estimated Q value ranges (which are not present in the volume of concern) in the cases of spore data from that work.  The reason for this is that absence of a range for Q prevents automated generation of a sporograph.  On this site, in every case in which data is available from the work in question, it will be presented without estimated values for a Q range; and a note explaining the action will follow the presentation of that data.  At present, this impacts the techtabs of the following taxa: Amanita angustispora, A. austrobulbosa, A. clelandii, A. kammala, A. luteofusca, A. subalbida, and A. variabilis.

The current form of the note is as follows: "Note: We have not estimated a range for Q based on the (Grgurinovic 1997) spore data for this species in order to prevent automatic generation of a sporograph that we believe would be misleading.  We evaluated the Amanita spore length and width ranges from (Grgurinovic 1997) in comparison to comparable data published by other authors and often based on revision of the same specimens.  This experiment involved a total of 19 descriptions of a total of 13 species from the work of 3 authors.  In a range of the form "x - y" of spore length (width) from (Grgurinovic 1997) compared to a range of the form (a-) b - c (-d) of spore length (width) in the other works, the value of "y" was compared to the value of "c" as a ratio.  In the case of spore length ranges, on average (per author), the ratio y/c ranged from 1.06 - 1.10 (possibly due to the non-segregation of a "d" value in the ranges of concern).  In the case of spore width ranges, on average (per author), the ratio ranged from 1.14 - 1.23 (indicating the probability of compounding causes at play—possibly, the absence of the "d" value in the ranges of concern and failure to restrict spore measurement to spores strictly presenting in lateral view).  When sporographs were attempted from the Grgurinovic data, the utility of the tool was significantly degraded in its usefulness.—ed."

22 June 2011

Updated techtabs: Amanita angustispora (extensive revision and revision of proposed placement to stirps Grossa) and A. subalbida.

Updated brief tabs: Amanita aurea and A. cruzii

Updated techtabs: Amanita aurea, A. aureofloccosa, A. cruzii, A. occidentalis, A. punctata, and A. subvaginata.

17-18 June 2011

Reassignment of provisional taxon: Re-examination of the single collection given the temporary code name Amanita sp-WY01 reveals that its spores are not "weakly amyloid" as previously described, but inamyloid.  This requires the movement of the entity to Amanita stirps muscaria.  The material may prove to be a very weakly pigmented variant of A. muscaria subsp. flavivolvata.

Updated brief tabs: Limacella lenticularis var. fischeri and L. mcmurphyi.

Updated techtabs: Amanita pelioma, A. roseolamellata, A. spreta, and Limacella mcmurphyi.

12-16 June 2011

New topic link on taxon pages: A new link appears with educational topics on the left side of taxon pages. The new topic explains the lamella edge tissue in Amanita and why the inflated cells of this tissue do not fit the definition of cystidia.

Name change: Limacella guttata var. fischeri turns out to be invalid.  We therefore must revert to an available name: L. lenticularis var. fischeri.

Updated techtabs: Amanita albifimbriata, A. brunneiphylla, A. carneiphylla, A. hiltonii, A. ochrophylloides, A. pagetodes, A. parvipantherina, A. peltigera, A. populiphila, A. pyramidifera, A. rosea, and Limacella lenticularis var. fischeri.

Updated techtabs: Amanita cinereoconia, A. protecta, and A. subcokeri.

6 April 2011

In recent days many collections have been added to the material examined data fields of many taxon pages.  We have had the opportunity to catalog dozens of collections that have been recently added to RET's herbarium.  At the same time, we added the material to the website. Over 620 collections now have lat./long. information sufficient to have them represented on automatically generated maps that have been under development in the last month or so. Still a long way to go with regard to mapping all the material we cite.

2-4 April 2011

BUG resolved: The display problem has been resolved. Please report broken links and any other site errors.

Updated techtabs: Amanita bisporigera.

12 February 2011

Revised and illustrated compilation of notes on mushroom poisoning: This document is especially focused on a user audience in the states of the central eastern portion of the U.S.; however, with different species examples, the document is generally applicable.  the added content and, especially, the added illustrations bring the document to over 1.5 MBytes as a PDF using Acrobat vers. 9 compatible compression.

New name: Amanita volvarielloides was described as new in 2009.  The authors of the name were not familiar with Amanita taxonomy and related morphological methodologies; nor did they have uptodate knowledge of molecular work in Amanita.  The resulting description is idiosyncratic and requires a thorough revision of the holotype.  The argument for novelty is not adequate; hence, the status of the species, one it is better known should be reviewed.

11 February 2011

Techtab update: The erroneous spore data from Jenkins' type study of Amanita suballiacea was on-line for a couple of months before RET caught it today.  The spore data from RET's revision of Murrill's type has replaced the erroneous data.  Jenkins' error appears to have been the substitution of a complete set of data for a different species for the data of A. suballiacea.

1-8 February 2011

Mapping data trials: Costa Rican data for Amanita conara, A. costaricensis, A. garabitoana, A. muscaria subsp. flavivolvata, A. sp-CR01, A. sp-CR02, A. sp-CR04, A. sp-CRO5, A. sp-CR09, A. sp-CR13, A. sp-CR16, A. sp-CR18, A. sp-HON02, and A. sp-M15.  These trials led to some reconception and redesign of the hidden "Materials" tab that will play a major role in mapping and the related projects such as regional checklists and regional pseudomonographs or field guides.  Further steps in automating the editing process for the requisite data should result.

Updated techtabs: Amanita atkinsoniana, A. aurantiobrunnea, A. calochroa, A. campinaranae, A. coacta, A. costaricensis, A. crebresulcata, A. cyanopus, A. lanivolva, A. onusta, A. perphaea, A. phaea, and A. xerocybe.

Error corrected: An error in the PDF file describing the drawing of a sporograph has been corrected. Thank you to Dr. Elaine Davison who detected the error and reported it to us.

30-31 January 2011

Updated techtab: Amanita dulciarii.

Additional or replaced illustrations: Amanita gayana.

27 January 2011

Bug: A bug that caused images to be removed from six taxon pages was identified.  Manual elimination of the bug now results in all the images being displayed once more.

Glossaries: Improvements have been made to the current Glossary page and interactions with site users will bring more improvements.  We are not interested in duplicating the glossary at the Agriculture Canada site to which we provide a link on the Glossary page.  We would like to focus on developing a site glossary that is useful to our users interested in the Amanitaceae.  To that latter end, we will distinguish annotations of glossary items from word definitions, and continue to add annotations.

22 January 2011

This morning received it 1,000th visit of the 2011.

At present we are working on a revision of the mushroom poisoning compendium PDF that is located on our our Mushroom Poisoning page.  This effort is a part of creating an initial program for Emergency Medical Services teams dealing with first response in cases of mushroom poisoning.
