Remarks (public):C. perennis in vitro possesses cottony brown colonies and a physiology similar to the Boletaceae and their gasteroid allies, thus potentially allowing confusion with Paxillus involutus or Pisolithus arhizus. However, these two latter species possess clamp connections, have non-pigmented hyphae, exude deep brown pigments into the agar (BAF and PDA) and are semi-tolerant to tolerant to sodium chloride. C. perennis lacks clamps, has lightly pigmented hyphae, exudes at most weak pigments into the agar, and is sensitive to sodium chloride.
Danielson (1984) reported the formation of a poroid hymenophore on the agar surface.

Description:Coltricia perennis (L. : Fr.) Murr.
MACROMORPHOLOGY: BAF: circular, 36-40 mm in diameter, sparsely cottony, brown (6E8), with a raised to ± appressed ± even margin. Reverse dark brown (6F8) surrounded by brown (6E8), with yellowish white (4A2) at the margin. PDA: circular, 30-32 as in diameter, sparsely cottony, brown (7E8), with a raised to ± appressed ± uneven margin. Reverse dark brown (6F8) with light brown (6D8) at the margin. Very slight pigment being released into the agar. MN: circular, 33-34 mm in diameter, sparsely cottony, brown (7EB), with a raised to ± appressed ± uneven margin. Reverse dark brown (7F8) surrounded by a thin band of greyish brown (7D3) then dark brown (6F8), with brown (6E8) at the margin. Hagem's: circular, 36-38 mm in diameter, sparsely cottony, brown (6E8) with a raised to ± appressed ±even reddish brown (8E8) margin. Reverse dark brown (7F8) with brown (7E8) at the margin.
