| intro |
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 collectors' notes on the fresh material and original research of R. E. Tulloss. |
| pileus |
70 - 80 mm wide, more or less uniformly reddish (6B-C7), with yellow showing between ridges of sulcate margin, convex to planoconvex; context dominantly white, unchanging, with yellow region immediately below pileipellis; margin striate; universal veil absent.
[Note: This can be extended from photograph.—ed.] |
| lamellae |
adnate, crowded, whitish with yellow tint in side view, with yellow fimbriate edge; lamellulae truncate.
[Note: This can be extended from photograph.—ed.] |
| stipe |
80 - 85 × 9 - 11 mm, orange (6A8) above partial veil, subcylindric, dry, with yellow ground, decorated with scattered orange (6A8) patches; context hollow, white, unchanging; partial veil orange (6A8), membranous; universal veil as saccate volva, white, membranous.
[Note: This can be extended from photograph.—ed.] |
| odor/taste |
Odor mild. Taste not recorded. |
macrochemical
tests |
none recorded. |
| lamella trama |
bilateral, divergent: ??. |
| subhymenium |
pseudoparenchymatous (cellular); inflated cells subglobose to broadly ellipsoid to ellispoid (e.g., 10.7 - 15.3 × 10.2 - 11.2 μm), in 2 (-3) layers below bases of longest basida. |
| basidia |
35- - 45+ × 8.3- - 8.5+, ??; clamps common. |
| basidiospores |
[40/2/1] (8.4-) 8.5 - 10.2 (-11.3) × (4.3-) 5.6 - 6.5 (-7.4) μm, (L = 9.3 - 9.6 μm; L' = 9.4 μm; W = 6.1 - 6.3 μm; W' = 6.2 μm; Q = (1.31-) 1.40 - 1.68 (-1.95); Q = 1.53 - 1.54; Q' = 1.54), hyaline, colorless or sometimes faintly yellow, smooth, thin-walled, ellipsoid to elongate, rarely expanded at one end, adaxially flattened; apiculus sublateral, cylindric; contents mono- or multiguttulate, with or without additional small granules; color in deposit not recorded. |
| ecology |
Paired. Associated with Allocasuarina littoralis and Eucalyptus intermedia. |
| material examined |
AUSTRALIA: QUEENSLAND—?? - N of Little Crystal Creek, Paluma Rd., 18.ii.1992 P. Reddell & M. Castellano s.n. [R. E. Halling 6815] [E No. 4682] (PERTH??; NY). |
| discussion |
The habit of the fruiting body of this species is more like that of the bright-colored central African taxa than like that of the southeast Asian taxa and A. sp-AUS02—in the present species the fruiting body has a proportionately shorter stipe than A. sp-AUS02 and a pileus with little or no umbo.
A sporograph comparison of the present species and A. sp-AUS02 follows:
