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 the collector's phtograph, molecular studies of Dr. Linas V. Kudzma and other original research of R. E. Tulloss. | ||||||||||||||||||||||||
pileus | grayish brown to dark brownish gray, convex; context ??; margin striate; universal veil in small, rather thin, rather small patches, scattered, rather pleniful. | ||||||||||||||||||||||||
lamellae | probably free, close to crowded, white in mass and in side view, with edges fimbriate or pulverulent; lamellulae truncate, plentiful, of diverse lengths, ??. | ||||||||||||||||||||||||
stipe | white, narrowing upward, sometime developing recurved and/or decurved scales; context white, becoming yellowish in larval tunnels; exannulate; unversal veil saccatae, white on both surfaces, often presistent at stipe base. | ||||||||||||||||||||||||
odor/taste | neither reported. | ||||||||||||||||||||||||
macrochemical tests |
none recorded. | ||||||||||||||||||||||||
basidia | ??, 4-sterigmate; clamps rare or absent. | ||||||||||||||||||||||||
lamella edge tissue | sterile. | ||||||||||||||||||||||||
basidiospores | [20/1/1] (8.3-) 9.5 - 12.2 (-13.5) × (7.5-) 8.6 - 11.0 (-12.5) μm, (L = 10.7 μm; W = 9.8 μm; Q = 1.06 - 1.14 (-1.17); Q = 1.10), colorless, hyaline, thin-walled, smooth, adaxially flattened, subglobose to broadly ellipsoid; apiculus sublateral, cylindric; contents multiguttulate; probably white in deposit. | ||||||||||||||||||||||||
ecology | Georgia: Gregarious. In sandy soil of grassy area with Pinus elliottii. Texas: At 21 m elev. Scattered to gregarious. In sandy soil, with Pinus taeda or among "upland pines." | ||||||||||||||||||||||||
