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 protolog of the present species unless otherwise noted. | ||||||||
pileus | from protolog: 60 - 130 mm wide, white, convex, slightly viscid; context white, 4 - 8 mm thick above stipe, rapidly thinning near margin; margin not described; universal veil absent or as few large patches. | ||||||||
lamellae | from protolog: free, density not reported, pale, ca. Cartridge Buff, 5 - 10 mm broad; lamellulae not described. | ||||||||
stipe | from protolog: 10 - 20 × 12 - 25 mm, white, barely attenuate near apex; context solid, becoming hollow with age; bulb 25 - 40 mm wide; partial veil fugacious; universal veil as limbate volva on upper bulb and as covering of small adpressed scales on stipe (these detersile and rapidly lost). | ||||||||
odor/taste | not recorded. | ||||||||
macrochemical tests |
none recorded. | ||||||||
pileipellis | not described. | ||||||||
pileus context | not described. | ||||||||
lamella trama | not described. | ||||||||
subhymenium | not described. | ||||||||
basidia | from protolog: 40 - 48 × 8 - 9.5 μm, 4-sterigmate. | ||||||||
universal veil | not described. | ||||||||
stipe context | not described. | ||||||||
partial veil | not described. | ||||||||
lamella edge tissue | from protolog: inflated cells globose to subglobose, 12 - 39 μm long. | ||||||||
basidiospores | from protolog: [-/-/-] 6 - 9 × 6 - 9 μm, (est. Q = 1.0 - 1.10), globose to subglobose, most common dimensions 7 - 8 μm long. [Note: Reaction to Melzer's Reagent not reported. With only one dimension, a sporograph cannot be generated. Hence, we made a conservative approximation of the range of Q and assumed identical ranges for width and length in order to generate an approximation of a sporograph.—ed.] | ||||||||
ecology | not recorded. | ||||||||
material examined | from protolog: INDONESIA: JAVA—Tjibodas, n.d. Bruggeman s.n. (syntype, ?BO, not found in BO per ZLY on 1996 visit), 13.vi.1940 Toxopeus s.n. (syntype, ?BO, not found in BO per ZLY on 1996 visit). | ||||||||
discussion |
No discussion was provided in the protolog. The proper placement of this taxon seems open to question. If the stipe is truly exannulate, then placement in sect. Phalloideae seems unusual. The inability to locate either of the potential syntypes leads us to treat the species as insufficiently known. This situation could be rectified if the syntypes are found and/or if the species were to be recollected and recognized with confidence. | ||||||||

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.
