=Armillaria floridana Murrill |
intro | This description is based on that of H. V. Smith (1945 ). |
cap | The cap of Limacella floridana is 45± mm wide, uniformly reddish-brownisn tan or slightly darker in the center, convex to plane, becoming slightly depressed, not umbonate,and somewhat viscid. The cap's flesh is white and unchanging. The gluten layer was not described explicitly. |
gills | The gills of this species barely touch the stem and are white and "fragile." Short gills were not described. |
stem | The stem is 50± × 7 – 9 mm, white, broadest in the mid-height region, smooth, dry and glabrous above, and viscid with fibrous scales below a "ring." No bulb was described, and neither was the stem's flesh described. There is said to be a ring at about mid-height of the stem; and this ring is said to be small, white, and persistent. Apparently, the gluten layer on the stem is present below the stem's ring. |
odor/taste | The odor of this species was described as faint and pleasant. The taste has not been reported. |
spores |
The available data on spores and basidial clamps is quite inadequate. The spores are said to measure "3.8 – 4.2 µm." However, they are unlikely to be globose as implied by the data provided. They are inamyloid and said to be minutely stippled. |
discussion | As is the case for most of the taxa in this genus, the available data is sparse; and a type study is necessary in order to begin to fill in the gaps. The description is strongly reminiscent of L. glischra.—R. E. Tulloss |

≡Armillaria floridana Murrill, 1943. Mycologia 35: 422. 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. | ||||||||
etymology |
Florida + -ana, suffix indicating possession; hence, "of Florida" Honoring the U.S. state of Florida. | ||||||||

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 based on that by H. V. Smith (1945 ). | ||||||||
pileus | Smith (1945): 45± mm wide, uniformly umbrinous isabelline or slightly darker on disc, convex to planar, becoming slightly depressed, not umbonate, uneven, somewhat viscid; context white, unchanging; margin undulate-even; gluten layer not described. | ||||||||
lamellae | Smith (1945): deeply emarginate, barely touching stipe, white, broad, ventricose, entire, inserted, fragile; lamellulae not described. | ||||||||
stipe | Smith (1945): 50± × 7 – 9 mm, white, subfusiform, smooth, dry and glabrous above, viscid and floccose-squamulose below partial veil; bulb ??; context ??; partial veil median, small, white, persistent; gluten layer as floccose-squamulose material supporting? gluten on stipe below partial veil. | ||||||||
odor/taste | Smith (1945): Odor faint, pleasant. Taste not recorded. | ||||||||
macrochemical tests |
none recorded. | ||||||||
pileipellis | absent. | ||||||||
pileus context | Smith (1945): "loosely floccose"; filamentous hyphae not described; acrophysalides not described; vascular hyphae scattered, “mostly” 2.1 – 4.2 µm wide. | ||||||||
lamella trama | Smith (1945): bilateral, but not easily observed in exsiccata; central stratum apparently lacking. | ||||||||
subhymenium | not described. | ||||||||
basidia | Smith (1945): 16.8 – 25 × 4.2 – 6.3 µm, 4-sterigmate; clamps not mentioned. | ||||||||
gluten layer | Smith (1945): On pileus: hyphae supporting volval gluten erect to "appressed," with terminal cells attenuated. | ||||||||

basidiospores | Smith (1945): "3.8 – 4.2 µm" [unlikely to be globose as implied by the single measurement given], inamyloid, minutely stippled; apiculus not described; contents not described; color in deposit not recorded. | ||||||||
ecology | Smith (1945): Solitary. In humus under Quercus. | ||||||||

discussion |
For some confusing Murrill names that are neither taxonomic nor nomenclatural synonyms of L. floridana, see (Volk and Burdsall 1995: 56). See also, L. oblita, which H.V. Smith suggests might be synonymous with the present taxon. However, the spores differ in both size and shape, according to Smith’s data; and she describes the partial veils in different terms. | ||||||||

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.
