    It's not typical for Oyster Mushrooms (Pleurotus species) to be found seemingly growing on the ground, although I have seen this a few times. What appears to be a terrestrial growth habit is due to the mushrooms growing from buried wood. But... The gills seen here appear to be tightly-spaced and quite shallow. I think these mushrooms may be a young cluster of Hohenbuehelia petaloides. Mushrooms of this species often have a shoe-horn shape when mature. H. petaloides has (finely) fringed gill edges. This species often grows from buried wood. Pleurotus mushrooms have gills that are broader, with even edges, and not so tightly spaced. A close examination of the gills may be a key here; or a photo that zooms in a little closer to the gills. Also, Oyster Mushrooms generally have a pleasant odor; some people describe it as anise-like, some describe it as like an ocean breeze. The odor of Hohenbuehelia petaloides is either indistinct or slightly mealy. If these are Oyster Mushrooms, then they are likely the species Pleurotus ostreatus (based upon the grayish cap color). Spore print color for some species of Pleurotus is white, but P. ostreatus has a pale grayish/lilac spore print. This subtle color is best seen by taking the spore print on a non-porous white surface. H. petaloides has a white spore print. It would be interesting to see if additional information provides a more definitive ID for these. I'd bet on the Hohenbuehelia proposal. Lentinellus cochleatus is also somewhat similar, bur usually with thinner flesh that has an unpleasant peppery taste and noticeably serrated/toothed gill edges.

    My first guess would be these are a species of genus Gymnopilus. Knowing the spore print color would be potentially useful. Here's something I found online that looks like the mushrooms seen in this thread http://australianfungi.blogspot.com/2007/03/5-gymnopilus-junonius.html. The author of this blog is calling the mushrooms Gymnopilus junonius. This is a species name often applied to North American collections. The name may or may not apply to a type found in Australia. I see online there are other sources that claim G. junonius occurs in Australia. Here's the Mushroom Expert account of Gymopilus junonius as it is understood in North America http://www.mushroomexpert.com/gymnopilus_junonius.html.
  3. Morels?

    The largest of the morels seen in the photo appears to have some mold on it. I would not eat this one... or at least I'd trim away the damaged parts.

    Length of day may be a factor, as this affects how much solar energy is available. Also, in an area like FL where there isn't any actual ground-freezing temps, times of year when mushrooms flush may be more-or-less a function of mycelium/fruit-body growth cycles that are at least similar from year to year. But, I think the idea of it getting too cold in your area has merit. It may be that fungal species in FL are not adapted to sub-40 degree temps. I'm guessing that some of the typical cold weather species I find up here in PA are absent in FL. For example, species of Hygrophorus (especially the slimy-capped ones), species of Tricholoma, Hericium. Do you get Blewits (Lepista/Clitocybe nuda) down your way?

    Desarmillaria tabescens is the new name for Armillaria tabescens. Apparently, DNA analysis has placed this species onto a branch of the phylogenetic tree that does not include species from genus Armillaria. What this means is, if you want to consult a source like Mushroom Observer to see "Ringless Honey Mushroom" observations then you need to use the current name, Desarmillaria tabescens. Sometimes it takes awhile before a new genus or species name shows up in the field guides. I've seen examples on Mushroom Observer where a given species gets kicked back and forth between two different genera. Fungal taxonomy is currently in a state of --occasionally fickle-- flux. Consider the species currently named Oudemansiella furfuracea (Rooting Collybia). The Audubon guide lists this mushroom as Oudemansiella radicata and mentions that a former name is Collybia radicata. After publication of Audubon, genus Xerula was erected and the name was changed to Xerula furfuracea. (In NA, the European species concept "radicata" does not apply, and subsequent research resulted in splitting the NA concept into several similar taxa.) A few years ago the genus Hymenopellis was erected to house the "Rooters", after which this mushroom was Hymenopellis furfuracea for awhile. Then, molecular data suggested that the species actually belonged in genus Oudemansiella... where it had been in the Audubon... except under a different species name. I *think* this historical perspective is at least close to being accurate. Finding this type mushroom when the temperatures are peaking in the high 90s seems --to me-- even weirder than finding them now! What sorts of nighttime lows are typical when the fall versions are found?
  6. Hello from Lake Winola, NEPA

    Hi Carole. Lake Winola is not very far from my neck 'o the woods. I may try my early morel spot tomorrow. Not any real high expectations, just a hunch. Black Morels start up around here as early as April 1. (Actually, I found a few March 21, 2012.) It's been consistently chilly around here... until today. Ground's been thawed for awhile, except for maybe the top inch or so on a cold night. During the first 2-3 weeks of May I have collected Yellow Morels in old apple orchards. But, VERY IMPORTANTLY some old apple orchards --perhaps mainly large cash crop operations-- were annually treated with the pesticide lead-arsenate during the period 1860-1960. I continue to harvest morels from a few local old/dying orchards. But, I have tested the soil for lead content. (Testing for arsenic requires sending out to a lab.) Results for the soil in small 2-4 acre overgrown local orchards I tested for lead came up showing no reason for concern in any of these particular locations. If you start a discussion under "General M D", I'll jump in. Morels are uncommon around here. But, I can offer a few tips on where they may be found.

    Okay, thanks Diana. Photos are now seen. Looks like Armillaria tabescens to me. I have seen other reports of early season A. tabescens from areas of SE NA, but not quite this early. However, mushroom seasons in FL are markedly different from what is expected further north. There a few available field guides specific to SE NA. I don't own any of these. I'm pretty sure that both the Bessettes and Bill Roody are very familiar with the mushrooms of FL. Do you have their SE NA field guide? If so, I'd be interested in seeing what they have to say about the fruiting season for A. tabescens. I assume you have observed a white spore print for these. There's a new genus for tabescens... Desarmillaria. Here's the MO section for observations of Desarmillaria tabescens http://mushroomobserver.org/observer/observation_search?page=1&pattern=Desarmillaria+tabescens. There's three pages of observations and some of them are from March/April. Here's an example from Texas http://mushroomobserver.org/274016?q=J6XU . Note that the ID proposal was made by Walt Sturgeon, a highly respected identifier of eastern NA mushrooms. Walt submitted his ID proposal at a modest level of confidence ("Could Be"), indicating that he was surprised by an occurrence of this species in early spring . Should be interesting getting into the woods after all that rain.

    Diana, for some reason I am unable to view your photos. Instead of pics, there's just a lot of code.
  9. Identification of wild mushrooms

    Need to see a few undersides of the caps as well as the entire stalks before a reasonable ID may be proposed.
  10. Two Stinkhorns in Japan

    Interesting. Thanks. Pseudocolus is a genus I had not known about. These look similar to Clathrus, and a few species appear to have been shuffled back and forth between Clathrus and Pseudocolus. http://www.speciesfungorum.org/Names/names.asp?strGenus=Pseudocolus
  11. ID help please

    I believe these are young specimens of Hypholoma lateritium (H. sublateritium in older field guides, aka. "Brick Cap Mushroom"). The gills are very pale as seen in the photos. But, if my ID is correct, then as the mushrooms matured the gills would have turned gray, and then eventually very dark gray. http://www.mushroomexpert.com/hypholoma_sublateritium.html The ones seen here are probably growing from buried wood.
  12. ID assistance please

    These latest ones are a species of Lactarius, one of the types with colorful latex. These types generally exude liquid/latex in very small amounts. To observe the latex, gently press either your finger or a piece of white paper against the cut flesh and then look for signs of color on the finger/paper. These types of Lactarius are mainly pine associates.
  13. Growing on logs in Hawaii

    This is a tough one. Maybe Xeromphalina? Maybe Omphalina? Panellus? I'm guessing this will have a white spore print. But even if this is correct... tough call for genus. Small wood-inhabiting mushrooms can be the among the most difficult to ID. Are the undersides of the caps true gills, or are they poroid?
  14. Two Stinkhorns in Japan

    I think they are each species of Clathrus, but maybe not the same species. Red one looks like C. archeri. http://www.mushroomexpert.com/clathrus_archeri.html Yellow one looks like something close to C columnatus. http://www.mushroomexpert.com/clathrus_columnatus.html
  15. ID assistance please

    Looks like possibly two different species in the photos. First four photos look like the European Boletus pinophilus, except the species similar to pinophilus grow under pine. Could there be one or two pines in the area? If not, it's not a major surprise to find species of King Boletes under oak... just not B. pinophilus. So, I'd guess these are a hardwood-associating species similar to B. edulis. Last two photos may show something different than the first four... or they may just be young versions of the others. It would be helpful to see the pore surface (underside of cap) as well as a view of a mushroom vertically sliced to show the cross section. If you cut/scratch the flesh, take note of any staining.
