  1. Best to see entire mushrooms photographed from different perspectives so that all readily observable traits are seen... cap surfaces, gills, entire stems. Also, any notable odor, staining or bruising (ie. color change of flesh or other part of the mushroom), spore print color. Even after all of this it's sometimes necessary to examine microscopic aspects. I *think* these mushrooms are examples of Megacollybia rodmanii, but not 100% sure. Never eat a mushroom that has not been confidently IDed.
  2. The second photo down is particularly useful in that it shows clearly that the gills are attached to the stalk. Otherwise the gills in early-maturity pink stage combined with the questionable presence of a partial veil may lead one to consider genus Pluteus. The 4th photo shows darker grayish gills that are more mature, which points away from Entoloma.
  3. My best guess for this is Picipes melanopus, an uncommon species in my experience. https://mushroomobserver.org/observer/show_observation/414233 https://mushroomobserver.org/379570?q=1nDDb . Formerly placed in genus Polyporus. Also, compare with Bresadolia craterells (formerly Polyporus craterellus). https://www.messiah.edu/Oakes/fungi_on_wood/poroid fungi/species pages/Bresadolia craterella.htm But, I like the first suggestion better, based upon what appear to be very small pores and cap surface lacking prominent scales.
  4. I think these are C. candolleanus... just rather small ones.
  5. Oh yeah... Here's a good one. Over the past maybe 30 years... Collybia luxurians ---> Gymnopus luxurians ---> Marasmiellus luxurians ---> Collybiopsis luxurians. These last three span less than 10 years. Often these changes are for good scientific reasons; for example when DNA mandates a taxonomic change of genus to accommodate the construction of phylogenetic trees, or the need for a new North American species name to replace an originally misapplied European name. But, sometimes a change is proposed for rather esoteric reasons like... Mycologist X originally proposed name X and then Mycologist Y proposed name Y to what they thought to be a novel species , but it was actually just X. Meanwhile DNA says there's a need for a new name for X, and so someone proposes a new name Z, writes it up, and Z is then adopted into the nomenclature. Then, someone else does some research and discovers that Mycologist Y had previously supplied what should now be the new name. So --according to the rules-- Z is then replaced by Y. Stuff kinda like that. Perhaps the craziest name-game change in recent history is what happened to the NA taxon formerly known as Suillus granulatus. It's now called Suillus weaverae. Because the new name is actually based upon an ID error some mushroom enthusiasts have taken a stand against using it. But, the name is legitimate. Long story. Some details found in the discussion under comments here https://mushroomobserver.org/318886 Look at the voting on the proposed names seen in this next linked MO observation https://mushroomobserver.org/242799?q=1nCz6 . BTW, the MO voter "else" is Else Vellinga, a prominent professional mycologist.
  6. I assume the location Manchester is the city in the United Kingdom. There's also a city called Manchester in the state of New Hampshire, USA. As for the mushrooms, we will have a much better chance to arrive at an ID if an entire fruit body is harvested and photographed from different perspectives... to show cap, underside (gills in this case), and the stipe including the base which may be buried. Often it is necessary to excavate to base of the stipe. Usually, it is sufficient to insert a knife blade into the ground and underneath the base in order to pop it out of the ground. Other ID features include spore print color and sometimes any notable odor. Also, it often helps to vertically section one mushroom so that the interior structure may be assessed. If in the UK, then Amanita rubescens look like a possibility. If in the USA then any of several similar species of Amanita --a few of which are currently unnamed.
  7. Correct! The new scientific name for "Common Psathyrella" is Candolleomyces candolleana.
  8. I received the sample yesterday. Dumped a bit of crushed material form a folded piece of wax paper, mounted in Melzers, and scoped. Spores are amyloid. Photo is taken through one eyepiece on my binocular scope. Viewed through my monocular scope --not as good but with reticle-- resolution was not quite good enough to tell the spores apart from the air bubbles. So --because I use photos through the mono scope to estimate measurements-- I don't have an update on dimensions. Amyloid spores eliminates the possibility of A. velatipes/subvelatipes. Assuming all three mushrooms represent the same species --I think so-- this says the section represented is either Phalloideae or Validae. (Sections Amidella and Lepidella feature much different morphology). The pigmented one is almost certainly not an example of any species in Phalloideae. Of the paler ones, the smaller shows some pigmentation on the cap. The only pigmented-capped Phalloideae I know from PA are A. phalloides and A. sturgeonii, and the mushrooms pictured do not look like either of these species. So, it looks like section Validae. The small size is wrong for A. brunnescens/aestivalis. So, I think this leaves two possibilities, A. solaniolens and A. lavendula group. Small size and early-season occurrence favors A. solaniolens. The darkest one is very likely an example of this species. The pale ones could psossibly be one of the species grouped under the heading A. lavendula group (formerly A. citrina). These types have globose/subglobose basal bulb similar to the ones seen in the photos. The basal bulb of A. solaniolens varies from specimen to specimen. Examples with roundish bulb are not uncommon. The basal bulb of A. lavendula is usually somewhat spongy/squishy, like a marshmallow. An interesting thing in genus Amanita is that at least some species occasionally occur in albino form. I think these are all A. solaniolens.
  9. Definitely Ganoderma tsugae. The stipe-like connection to the tree (hemlock) is typical for this species.
  10. My first guess when seeing these photos was "Lentinus levis". But the stem is not hairy and the gill edges appear to be somewhat jagged (sawtooth/serrated), which would be incorrect for L. levis (unless the appearance is due to something munching on it which looks like it may have been the case). The same things apply to the very similar Pleurotus dryinus. Other species of Pleurotus have softer flesh (this one looks kinda resilient). Neolentinus lepideus is similar and has serrated gills but grows on conifer wood, usually pine. .
  11. I think these are Cryptoporus volvatus, the "Veiled Polypore." If correct, then the underside of a given fruit body may be punctured and stripped away revealing a small chamber beneath a pore surface. https://www.mushroomexpert.com/cryptoporus_volvatus.html
  12. Species of mushrooms in the Coprinellus micaceus group are safe to cook and eat. In general, I don't know any Coprinellus species that are toxic. One thing to consider is that a beginner may misidentify a Coprinopsis mushroom as Coprinellus. At least some Coprinopsis species will cause illness if consumed before, during, or after alcohol is consumed. http://www.mushroomexpert.com/coprinopsis_atramentaria.html It is your decision whether or not to consume a given collection of wild mushrooms. My advise is to acquire a general knowledge of the wild mushrooms that are apt to occur in your area. There's a mushroom club in Colorado that would be helpful https://cmsweb.org/about/
  13. Species of Coprinellus, one of which is C. micaceus (Mica Caps). The one seen here nay be this species. Coprinellus mushrooms do not always turn into an inky substance. In dry weather they may just dehydrate and shrivel.
  14. I think this is a species of Neofavolus. The fairly large polygonal pores and consistently fan-shaped caps suggest this. Most field guides document Neofavolus alveolaris, which is usually orange-capped, at least at maturity. Recent research suggests the white ones may be a different species. I believe the name suggested is N. americanus. The ones seen here look to be very fresh/young. So, it may be that they will develop more pigment as they mature.
  15. We generally don't discuss psychoactive fungi on this website. For that type of information Shroomery is probably best. I don't know the species of the mushrooms pictured. Psilocybe cubensis is a common species in FL. But, the long thin stem and lack of partial veil seem wrong for this species.
  16. The large mushrooms appearing to be growing on the ground are actually growing from buried wood, probably roots. They are a type of polypore, ie. no gills on the underside. Rather the down surface is composed of pores, probably very small pores. So, the surface may just appear to be smooth. But with minor magnification you should see te very small poles (possibly only the size of pinpricks). These look like some species of Ganoderma, but not one that grows up here in PA. I did a little checking and here's what I found. https://blogs.ifas.ufl.edu/collierco/2018/07/10/ganoderma-butt-rot-is-fatal-to-palms-know-what-to-look-for/ https://edis.ifas.ufl.edu/pdf/PP/PP100/PP100-9167470.pdf Looks like Ganoderma zonatum is a good possibility. If it's growing on palm, then that's very likely what it is. The clusters of smaller mushrooms on/near the log look like a species of either Panus of Lentinus. Some species have been shuffled back and forth between these two genera (genuses). I think the ones seen here may be Lentinus crinitus. This type mushroom is generally hairy, as seen in the link below. Looks like the photos posted here by Shroomie show old specimens with the hairs all matted down onto the cap surfaces. If correct, the undersides of these will have gills. https://www.texasmushrooms.org/en/lentinus_crinitus.htm
  17. A. subvelatipes ( and the similar A. velatipes) has a "rolled sock" basal volva. This may also be described as a rim encircling the top of the basal bulb. Sometimes I describe it as an abrupt margin. The basal volval on these looks more uneven and membranous-limbate (meaning portions/patches reach up along the lower stipe. The bulbs look more globose than I'd expect for velatipes/subvelatipes. The spores of velatipes/subvelatipes are larger and closer to ellipsoid (larger Q) than the spores seen here. These cap are unexpanded, so it's difficult to tell if the expanded ones will have striate margins. Young caps of velatipes/subvelatipes are difficult to assess as striate/nonstriate. I'm guessing you are correct the three all represent the same species, based upon size/stature. Is that largest one as pale as it looks in the third photo down (first one showing the mushrooms)? Dos it have the same type of globose basal bulb? The very white appearance looks like a Destroying Angel. A. bisporigera can be small/slender (it's the smallest of the DAs). But, I suspect the one seen here is a pale version of the same species as the more pigmented ones. I think the first thing we would like to know is whether or not the spores are amyloid. It would be good to know this for each of the three, as it's not completely clear to me these all represent the same species. This would require the use of Melzer's reagent, which is very difficult to obtain. I think these may be either A, solaniolens or one of the A. lavendula species. The spore dimensions and small fruit bodies match A. solaniolens, although the pale caps would be unusual for this species. A. solaniolens/lavendula are housed in section Validae, amyloid spores. Also, DAs --section Phalloideae-- have amyloid spores. A. velatipes/subvelatipes are from section Amanita, inamyloid spores. These look like healthy specimens. A harvested amanita fruit body will often continue to expand, even if just left indoors atop a table. Seeing expanded caps would be helpful. Also, as the caps expand spores should be dropping. If you collect spores on a piece of wax paper you can fold the pieces of wax paper and mail them to me. I could test spores for amyloidity. A substantial spore deposit is best for doing this. Send me a PM via WMH if interested.
  18. Megacollybia. The most common such species is M. rodmanii. Older field guides use the name Tricholomonpsis platyphylla. Common name is "Platterful Mushroom". Although listed as edible in some guides, most people who try eating it are --at best-- unimpressed. Neither flavor nor texture is rated as being good. And some people are sickened by it. The fibrous stems are likely indigestible.
  19. I don't think this is Ipex lacteus, but I don't have a confident proposal. http://www.mushroomexpert.com/irpex_lacteus.html https://www.mycoquebec.org/bas.php?trie=I&l=l&nom=Irpex lacteus / Irpex laiteux&tag=Irpex lacteus&gro=121 Here's a species I ran across on the internet https://www.first-nature.com/fungi/postia-placenta.php . Doesn't quite look right, though. Stumped by this one.
  20. Do these two photos show the same fungi?
  21. Candolleomyces candolleanus, formerly Psathyrella candolleana.
  22. Not Armillaria. These are likely Neolentinus lepideus. http://www.mushroomexpert.com/neolentinus_lepideus.html
  23. I agree with Cajun. Some of the telling traits are... large fronds (larger than for Maitake), black/gray bruising/staining, and perhaps most telling is time of year. Grifola frondosa (Maitake) is rarely seen earlier than mid August.
  24. Best to create a new discussion when the topic is changed. I don't have a confident ID proposal for this. But, I don't think it's a species of Pleurotus (ie. it's not an Oyster Mushroom). Maybe compare with species of Hohenbuehelia? If it's a species from this genus then microscopic analysis would be useful.
  25. I think these are Gymnopus semihirtipes http://www.mushroomexpert.com/gymnopus_semihirtipes.html . Usually, mushrooms of this species have stalk base that's hairy.
