Description:Lentinus striatulus Lév.
Wholly white, then cream, subochraceous with age; stem often fuscous.
Pileus -14 cm wide, at first convexo-umbilicate, then infundibuliform, wholly finely and thinly villous (-250 µm thick), scabrousvillous towards the fimbriate edge, becoming nearly smooth and innately streaked; margin finely villous to subspiculose or fimbriate with hyphal fascicles 0.3-1.5 mm long. Stem 1-3 cm x 4-9 mm, central becoming excentric, occasionally lateral, relatively short, cylindric, finely villous, becoming fuscous at the base and often with small appressed fuscous squamules upwards to the smooth white apex. Gills decurrent, crowded, 30-40 primaries 1-3.5 mm wide, 4-6 ranks, not furcate, edge entire to minutely denticulate, without or with sparse hyphal pegs. Flesh 2-4 mm.thick at the base of the pileus, tough, pliant. Smell strong, pleasant, rather of Marasmius oreades.
On logs and stumps in the forest and in the open, tropical America. Spores 5.5-8 x 1.5-3 µm subcylindric. Cystidia none, the gill-edge with sterile collapsing basidia. Pleurocystidia none.
Hyphae dimitic with skeleto-binding cells; generative hyphae clamped, 1.5-4 µm wide; skeletal cell-body 100-800(-1200) x 5-10 µm elongate fusiform, 3-5 µm wide at the ends, intercalary and terminal, becoming very thick-walled with linear lumen; binding processes -350 µm long, 0-3 times furcate, a distal forward process, a basal
backward process, and mostly 1-2 lateral processes, tapered to filiform tips, some with irregular branched to subcoralloid tips. Gill-trama with radiate construction, then interwoven. Squamules on the stem composed of clusters of short hyphal ends, 1-2 septate, the cells 10-35 x 4-6 jm, with dark brown and slightly thickened walls, clamped. Surface of the pileus with a lax pile (100250 µm thick) of generative and skeletal hyphal ends in fascicles 30100 gm wide, the skeletal hyphal ends with short and scattered processes.
I have described this species from living specimens which I collected in South America, because it needs comparison with L. squarrosulus of the Old World; L. striatulus differs in the smoother pileus and the paucity or absence of hyphal pegs. Panus calvescens Berk is synonymous. According to Singer the earliest name for this species is L. fockei Miq. (1852). L. hirtus Fr. is said to be close but with wider spores -8 x 4 µm (Dennis 1970).
