Characteristics:

No spores printing.

Cap: (Fig1) Convex, smooth but not shiny, dry cap surface with inhomogeneous yellow in young to dark brown-red when old (B. badius is homogeneous brown in cup surface and only slightly turns blue after cut). Cap size is 1.5-2.5 cm in thickness and 4-10cm diameter.

Hymenia: Yellow pores layer directly attach stem and flat (Fig2). It presents a reddish tissue layer between mature pores and immature hyphae locating 1-1.5cm under cap surface (Fig3).

Stem (Fig1-3): Thick wine bottle-like, with brown-red not sure reticular surface with yellow base color (B. badius is reticular), nearly no swelling but turning lightly tapering and brown towards the base close to the stem bottom, 2-4cm diameter and 8-12cm in length.

Color turn significantly blue when hurt (Figure 3-5).

Live associate with tree so most living close to trees as macrrhizal.

6 7Characteristics:

Spore: Dark chocolate brown spore print (Fig3, 6). Subglobose, smooth (Other similar appearance species except A. bernardii and A.devoniensis are ovoid or ellipsoidal shaped), hyaline spores, ~5µm diameter (Fig7 in 40x).

Gills: Free connect to stem, pink in young to brown after old and dry (Fig2, 4). Gill hide under cap when young (Fig 2) but bulge out as convex (Fig 4) and cap becomes relative flatter (Fig5).

Cap: White convex dry cap with litter white peal on surface but totally is smooth (Fig1) (A. bernardii is covered by coarse brown scales). Surface become crack after dry. Cap margin slightly in rolled when young and turns flat

after mature with a thin double ring (Fig4, 5) (A.devoniensis doesn’t have ring). 5-15cm diameter with 3-6cm thick in size of cap.

Stem: ~2cm diameter with 10cm in length of stem. Partial veil (ring) with thick white mycelia sheathing near the base of stem. Fibrillose to woolly below the ring zone.

4 5Characteristics:

Spore: Light brown (Fig4). Ellipsoidal, smooth, hyaline. ~7 X 10-12 µm. Thick-walled, with a broad apical germ pore (black dot on the polar of spore) (Fig5).

Gill: Free gill (C. tenera is adnexed gills with brown cap) with light yellow-pink (same as the cap) in young and cinnamon when old.

Cap: Conical cap is pale cream but turns flatten out with yellow coloration towards the central as radial striate. Thin small cap (2-3cm diameter) and broken in the edge. Surface is not viscid.

Stem: Bare fragile stem is 2-3mm diameter (C. pubescens is thin in 2mm diameter) and 5-8cm in long with the same color (creamy tint pink) as cap.

5 6Characteristics:

Spores: Green spore printing (Fig4, 5) (Other Chlorophyllum species are white or brown spores). Smooth; ovoid to elliptical; size in 5-7 x 9-12µm (Fig6).

Gill (Fig4): Free gill; after dry, gills turn green since the green spore coloration.

Cap (Fig1-5): Cap size in 5cm-15cm diameter and only about 1cm in thickness. Convex cup with central swelling like the umbrella. Light brown relative rough scales may present but the central is covered all by rough darken scale. Cap surface is smooth and white to lightly yellow on both cap and gill sides.

Stem (Fig2, 3): Smooth, firm with partial veil, white in young and turn brown with age and dry; 1-2cm diameter and 8-12cm long depending on the size of whole body.

4 5 6Characteristics:

Spore (Fig5, 6): White, cylindric, slightly curved, hyaline, smooth (Oxyporus populinus is subglobose); 2-3 x 5-6µm.

Growth (Fig1): alone or large imbricate clusters around dead tree stump.

Stem/hymenia (Fig2, 4): No stem with tiny white concolorous tube pores (not pores maze-like or slot-like, as Trametes. gibbosa) in density of 1-2 pores/mm with 1cm in depth (Trametes. suaveolens is 0.5-1mm spaced).

Cap (Fig1-4): Often imbricate and laterally fused; size in 5-10cm radius but is semi-circle. Relatively irregularly top-shaped; upper surface pale cream colored to buff or darkening with age, with unclear pinkish buff to cinnamon or clay color azonate on the surface ( darken with the age) (most other white-yellow, no-stem American polypore are with clear zones on cap and not cylindric spores). The central of the fruit root in 2cm radius is darker; a clear 2mm dark yellow-brown thinner border on cap without folding. Sponge-like relative soft fruit body with sterile surface (T. caesius, T. fragilis and other spp. in Trametes genus are downy).
